Business plan waterproofing with liquid rubber. Liquid rubber waterproofing business

Example 1 There is a foundation of a cottage under construction with a perimeter of 150 meters and a height of 3 meters.

The design is characterized by a complex perimeter geometry. Also, shells with a depth of more than 1 cm are noted on the foundation (they are formed during poor-quality formwork pouring of concrete). The total area of the sinks is 10 m2. Also, the presence of four joints of the foundation slabs along the vertical and complete adjoining of the junction of the foundation walls to the foundation lens. The foundation also has 8 corners at 90 degrees (i.e. sharp corners).

Foundations of any type, especially of complex geometry (and there are now the majority of such foundations, because projects often include wine cellars, billiard rooms, swimming pools, etc.) - this is the work that can be done efficiently and quickly only with the help of seamless spraying technology waterproofing liquid rubber.

Scope of work for this object:

The total area of the foundation is 450 m2, of which 150 m2 is at a depth of more than 2 meters;
The total area of shells with an average depth of 1 cm is 10 m2;
The total area of joints, corners and junctions is 4x3m (linear footage of joints of foundation slabs vertically) + 150m (linear footage of junctions at the junction of foundation walls to the foundation lens) + 8x3m (linear footage of 8 corners of the "type" 90 degrees) = 12 + 150 + 24 = 186 m2.

Applied equipment (prices as of autumn 2015):

RX-28/220V installation (the choice is due to the lack of 380V power supply on the site). Cost - 168,500 rubles;
Overalls, electric stirrer, working tools - according to the list of additional equipment and accessories for the RX-28/220V unit. The cost is about 11,500 rubles.

TOTAL equipment - 180,000 rubles.

Raw materials and consumption of materials (prices as of autumn 2015):

Two-component waterproofing system "Liquid Rubber for underground structures" - 300m2 x 3l/m2 (foundation waterproofing at a depth of up to 2 meters) + 150m2 x 4l/m2 (foundation waterproofing at a depth of more than 2 meters) + 450m2 x 0.5l/m2 (preliminary priming waterproofing surface) = 900l + 600l + 225l = 1775 liters. Cost 1775l x 125 rubles / l = 221875 rubles;
Calcium chloride, 2 bags of 25 kg (based on 1 bag per 1000 liters of "Liquid Rubber"). The cost of 2 bags x 1000 rubles / bag = 2000 rubles;
Geotextile substrate - 0.2m (width of the reinforcing strip) x 186m2 (total area of "dangerous" places) = 37.2m2. Cost 37.2m2 x 20 rubles / m2 = 744 rubles;

TOTAL for raw materials and materials - 224619 rubles.

Time required to apply liquid rubber:

Embedding and waterproofing sinks 10 m2 - 2 hours.
Preliminary priming of the waterproofed surface 450m2 x 0.5l/m2 = 225l - 30…45 minutes (taking into account possible stops).
Rolling of geotextiles in "dangerous" places of joints, corners and junctions: 0.2m (width of the reinforcing strip) x 186m2 - 3 hours (slowly and efficiently).
Application of liquid rubber 1500 l. - 3.5 ... 4 hours.

TOTAL for the time spent: 9 ... 10 hours.

Economic evaluation of roof waterproofing with liquid rubber.

The reliability and durability of flat roofs is guaranteed by the use of modern building technologies and materials, such as liquid rubber. Such roofs are distinguished by: water resistance, incombustibility, ease of installation and maintenance, and long service life.

With regard to soft roofs, there are 2 types of work:

1. Overhaul of the roof - includes a complete removal of the old waterproofing (usually: ruberoid) coating, repair of the screed, laying a new roofing carpet.
2. Current repair of the roof - consists in replacing defective sections of the old roofing material, sealing holes and cracks and laying new material.

Example 2 Capital repairs of a flat roof.

Number of aerators 1-2 pcs. for 50-100 sq. m. The cost of one standard roof aerator is 700 rubles per piece. The cost of its installation is 350-400 rubles per piece.

In places of swelling, a cross-shaped incision should be made (opening with an "envelope"), bend the panel, thoroughly clean the base, dry it with a gas burner flame and apply mastic both to the base and to the carpet panel. Then the bent edges of the carpet are returned to their place and pressed. For this operation, it is advisable to use ready-made cold mastics.

The cost of one-component mastic is 250 rubles / kg, consumption is 1.5-2.0 kg / sq. m.

Places where the roll material is completely rotted must be cut out. Thoroughly clean the resulting recess, fill with cement-sand mortar.

The more accurate the cutting will be, the less it will be necessary to repair the screed. To repair a cement-sand screed, a solution of a grade of at least 150 is used. After 8-10 days after laying, the screed is primed. Bituminous polymer mastic (liquid rubber, without hardener) is used as a primer.
Consumption 0.5 kg per 1 sq. m, the price is 125 rubles / kg.

Reinforcement increases the strength, but reduces the elasticity of the mastic coating, so it is necessary to understand what is preferable for a given roof. Reinforcement can be performed only in individual nodes (usually adjunctions and mates).

Reinforcement is done as follows. A thin layer of liquid rubber is applied by spraying (without hardener), with a consumption of 0.3-0.5 kg geotextile is laid and rolled to ensure a snug fit to the base over the entire surface, then a thin layer of liquid rubber is applied on top - consumption of 0.5 kg / sq m for impregnation of geotextiles, exposure to complete drying 2-5 hours.

After carrying out all the above works, the installation of the main waterproofing coating (liquid rubber) is carried out.

Bitumen-polymer mastic is applied by spraying, for this work, equipment of the RX series for liquid rubber is used.

The consumption of bitumen-polymer mastic is 3.0 kg per 1 sq.m to provide a waterproofing layer of at least 2 mm.

The cost of 1 kg is 155 rubles.

Example 3 Repair of a flat crawl of an industrial building 20x30 m.

The total coverage area is 600 sq. m.
Old roofing material. There are swellings on the roof with a total area of 100 sq m.
When removing (cutting out) swellings, depressions 30 mm deep were formed.

Approximate cost estimate for materials:

Name of materials	Unit measurements	Price	Qty	Material consumption	Total, rub.
sand cement	Bag (50 kg)	250 rub/mesh		1.2 mesh/sq m (screed thickness 30 mm)
Geotextile		20 rub/sq m
aerator				1 piece/100 sqm
Primer and impregnation of geotextiles (Daklar)
Basic waterproofing layer (Daklar)

Liquid rubber- a relatively new waterproofing material with a wide range of applications in the construction of any objects. It is a polymer-bitumen water emulsion, which is brought to the state of mastic in a special apparatus.

Liquid rubber has excellent performance in its main purpose - sealing and insulating joints, seams, any types of joints and surfaces, vertically, horizontally located, provides excellent adhesion, is not affected by high temperatures, does not crack, does not peel off. This is a universal building material that does not contain harmful and toxic components. The product is just entering the market, so the number of companies providing sealing and waterproofing services with liquid rubber is very small, and in some regions there is even zero competition. Therefore, this can be used to create a successful and profitable business based on this innovative and safe surface treatment method.

Consider the main cost items for bringing a business project to life.

Registration of activities - $ 625. The IP form is ideal.

Purchase of equipment - 3750 c.u. for a Russian-made apparatus, $5625 - for imported installations for working with polymer-bitumen water emulsion. The raw materials used in the devices may vary depending on the manufacturer, as a rule, the manufacturer adapts the spray machine to its type of raw material or can recommend a supplier of liquid rubber of the desired brand. When choosing equipment, you should pay attention to the type of power supply; mobile units operating on liquid fuel are convenient.

Rubber is supplied in the form of a liquid or in a solid state (granules). Material consumption - 2.5 l (or 3 kg) per 1 sq.m. of the treated area, with such indicators, the insulation layer will be 2 mm, an increase in thickness leads to a proportional increase in consumption. The price of 1 kg of polymer-bitumen mastic is $4. It is necessary to spend about 3,000 USD on the first batch of raw materials.

The process of applying sprayed seamless waterproofing itself is not complicated, but it is still desirable that the performers - the business owner himself (when working alone) or hired personnel - have at least minimal knowledge in the field of construction and waterproofing processes. Once again, we note that liquid rubber is a universal material, applied to any type of surface, various objects - from roofs, ceilings to foundations, pools, artificial reservoirs. The geometry of the location (tilt, vertical) does not matter, the only condition is that outdoor work should not be carried out in rainy weather, at sub-zero temperatures.

At the initial stages of activity, while there are few orders, one specialist can handle the work. It must be provided with passenger cars for trips to customers, for the transportation of consumables (liquid rubber has a considerable weight) and spray installations.
As a result, it will be difficult for one person to cope with the entire front of work, so the staff can be expanded to several workers, a construction specialty or with experience in interior decoration. They need a small truck. The cost of such transport will be about 9500-10000 USD. (for a supported car).

Personnel must be provided with protective waterproof suits, rubber gloves, boots, and respirators. The cost of uniforming one employee is $ 300.
The presence of an office is not necessary, many entrepreneurs make do with their own website, taking orders through it or by phone, calling a team as orders come in.

Initial investment to implement a business idea:

Total $11270. Monthly expenses - 1700 c.u.

You can significantly reduce monthly expenses and the amount of start-up capital by refusing to rent premises for an office and a warehouse (by switching to home or garage storage), by doing all the work yourself, by reducing the volume of purchased raw materials.
The cost of waterproofing with liquid rubber is about 20 USD. per 1 sq.m. The cost of the service is $4.2.

Business profitability - 75%.

To assess the economic efficiency of waterproofing with liquid rubber, we consider 2 types of the most typical works. On this page of the site, we will analyze the waterproofing of the foundation, and then we will calculate the repair of a flat roof.

The task of waterproofing the foundation

Construction of a cottage with a basement. Dimensions 15x11. To simplify the calculations, we assume that the cottage has a rectangular shape. In fact, the perimeter line can be of any shape. One of the advantages of liquid rubber is that it is convenient and quick to apply waterproofing to walls of any configuration.

Because building with a basement, the cottage is built on a monolithic slab. What is it and why should it be so for a house with a basement. Height of foundation walls, incl. plinth, from the top point of the foundation slab is 2.5 m.

Thus, the task involves 2 stages, separated by time.

First, waterproofing the base of the foundation slab. By the way, the video of such work is for a multi-storey building, and the video is for a cottage under construction.
Secondly, the waterproofing of the foundation walls.

When waterproofing the base of the foundation slab, waterproofing is carried out on lean concrete. When waterproofing walls, the vertical waterproofing is joined with a strip of horizontal waterproofing protruding along the perimeter.

Evaluation of the scope of work and the cost of the order

Thus, the task is to first apply waterproofing on a horizontal concrete base on an area of 165 m2, and then, after pouring the slab and walls, perform vertical waterproofing on the area: 2x(15+11)x2.5=130m2.

With a waterproofing thickness of 3 mm (corresponding to the consumption of liquid rubber 4.3 kg / m2), the average price for 1 m2 of coating along the horizon (labor + material) is 830 rubles.

Note that this is the "maximum" price in Moscow and the Moscow region in the summer season of 2014, which allows a discount for the customer up to 100 rubles per square. If you declare a price of more than 830 rubles, then it will be higher than the average value for the market, so there is a possibility that the Customer will not contact you.

Thus, up to 136,950 rubles should be received from the customer for waterproofing the foundation slab.

Similar prices for applying liquid rubber to walls are slightly higher, because. factor is taken into account. Service price (work + material) per 1 sq.m. for walls is 850 rubles. Thus, for this example, the market value of treating the foundation with liquid rubber is: 130 x 850 = 110,500 rubles.

Foundation preparation work

It is important to understand here that before laying waterproofing (any) the base must be prepared. It must be strong, smooth (fill in sinks, cavities, cut or knock down protruding stones, etc.) and clean. Be sure to install fillets at the junctions. These aspects are described in detail in the Liquid Rubber Leaflet,.

Most objects require foundation preparation. It will take time and additional labor. For a small business, it is preferable that this stage of work be carried out by others, but with the obligatory acceptance of the foundation by you. If it concerns a construction company that has both hands and resources, then it is more profitable, of course, to take on this stage of work as well.

Here, for the business plan of a small business for the provision of liquid rubber services, the preparation of the base is not taken into account.

The advantage of the liquid rubber business lies in mobility and responsiveness. On the appointed day, bring barrels with raw materials to the object by truck, bring the installation, quickly turn around, complete the application in 2-3-4-5-6 hours, roll up, pick up the installation and leave.

Be sure, before bringing barrels and equipment to the site, you should leave, inspect and make sure that everything is ready. On the word, “like we have everything ready, come tomorrow” - you should not believe the customer.

Works on the application of liquid rubber and related

In the presence of all necessary equipment and devices, the minimum speed of laying liquid rubber is 120m2 per hour, at a flow rate of 4.3kg/m2 of bituminous emulsion, which corresponds to a coating thickness of 3mm.

However, it should be borne in mind that there are always stops, breaks, etc. Therefore, in order to realistically estimate the time for the direct application of liquid rubber, a correction factor should be used. When working on the horizon, this is 0.7, and along the walls - 0.5.

Therefore, it will take 165 / 120 / 0.7 = 1.96 hours directly to spray liquid rubber on 165m2 of footings, i.e. 2 hours.

Therefore, directly spraying liquid rubber on 130 m2 of walls requires 130/120/0.5 = 2.17 hours, i.e. 2 hours and 10 minutes.

The time to deploy to the site averages 2 hours.

It is required to unload the barrels, spread them around the perimeter. Then download the installation. Solve the issue with the connection point if an electrical installation is used. In this regard, it should be noted that gasoline equipment is more convenient, because. autonomous and does not depend on anything on the object. In addition, hoses (from the installation to the place of application) can be up to 100 m, which allows you to work from one point, without moving equipment and drums.

Emulsion barrels should be opened. Prepare a solution of calcium chloride. The equipment must be depreserved, if necessary - adjusted, make sure that the coating will be obtained correctly.

In a word, if you know how and understand everything, then in 2 hours you can prepare for the start of work.

Prior to the two-component liquid rubber application, the substrate to be insulated must be primed. The emulsion itself is used as a primer, without an activator solution.

After the application of waterproofing is completed, time is required for “clotting”. It's easier here: flush the hoses and pumps, preserve the plant, roll up the hoses, wrap them in foil if necessary. Immerse the installation, tools, working containers into the machine.

On average, it takes at least 1 hour to roll up at the facility.

We recommend discussing with the Customer in advance the issue of empty barrels that will remain after applying liquid rubber. In order not to spend money on a truck for their removal, agree in advance that empty containers remain at the construction site.

Consumption of raw materials and other materials

The main cost item for the seamless waterproofing business is the liquid rubber itself, i.e. bitumen-polymer emulsion.

Liquid rubber consumption is determined by the requirement (and wallet) of the customer. Wants to get a better (thick) coating - you need more liquid per 1m2. Need cheaper and no warranty requirements? You can reduce the consumption and up to 3kg/m2.

For this example, we assume that the consumption of liquid rubber is 4.3 kg/m2 to obtain a coating with a thickness of 3 mm. This is a good value. But, unfortunately, only 20% of firms in Russia work this way.

For horizontal waterproofing of 165m2, 165 x 4.3 = 709.5 kg is required. You should also take into account the consumption of the emulsion for priming the base. On average, 0.2 kg/m2, i.e. 33kg. Total, 742.5 kg. Practice shows that the calculated value should be increased by 5%. We get 780kg.

Powder consumption is, on average, 4 kg per barrel. Thus, in the first case, 16 kg of CaCl2 is required, and in the second, 12 kg.

Diesel fuel consumption

Another cost item is diesel fuel for washing the plant. How equipment is flushed and preserved, how often it should be done, etc. - all this is described in detail in the technical data sheet that is sent along with the installation.

The consumption rate of diesel fuel is 40 liters with a hose length of 20 m. But these 40 liters are divided into "20 liters of clean" and "20 liters of dirty" diesel fuel. In fact, every 20 liters of diesel fuel are used twice: for a final flush today and a rough (first) flush tomorrow. Thus, the real consumption of pure diesel fuel is 20 liters.

If you build up pipelines from pumps to a fishing rod, and for a gasoline installation the maximum extension is 80m, then the diesel fuel consumption rate increases. Every 20m of hose extension requires an additional 20l of flushing fluid. For example, if the length of the hoses is 60m, then 40+20+20 diesel fuel is required, i.e. 80l, of which 40l is “dirty” and 40l is clean solarium.

For the problem under consideration, we assume that the hoses were not built up, i.e. the basic delivery set is used, where from the pump to the fishing rod 20m.

Transport costs and more

Transport costs should also be included in the cost. For our example, 4 barrels should be delivered to the construction site the first time, and three barrels the second time. The best option is the Gazelle, which will need to be hired.

In the case of Moscow and the Moscow region, the price consists of hourly payment and payment for each km of run from the Moscow Ring Road around the region. For example, in the summer of 2014, the tariffs were as follows:

The cost of 1 hour = 400 rubles.
The cost of 1 km from the Moscow Ring Road = 12 rubles.

If it is required to deliver the barrels to Klin (95 km from Moscow Ring Road along the Leningradskoye Highway), this will take approximately 4 hours, because the starting point is located in the south of Moscow, at the intersection of the Moscow Ring Road and Kashirskoye Highway, where the main warehouse of Technoprok is located.

The total costs will be 400x4 + 95x12 = 1600 + 1140 = 2740 rubles.

In other regions of Russia, prices may be different, but, on average for the country, 3,000 rubles should be planned for this section of transport costs.

Transportation costs should also include the cost of gasoline, which will be spent to get to the site in your car. You will need to visit at least three times:

For the first time, to inspect the object, agree on a price and explain what and how to prepare before applying waterproofing.
For the second time, to make sure that the base is ready for applying liquid rubber (you should not believe a word - only a personal visual and organoleptic examination).
For the third time, to come along with the installation for applying liquid rubber (barrels, as a rule, go separately by hired Gazelle).

On average, the cost of fuel for your car for 1 object is 2000 rubles.

Unforeseen expenses may also arise: pay someone, buy something, etc. Fund for contingencies 5000 rubles.

Business plan costing

So, let's bring together the items of expenditure listed above, in relation to the example under consideration.

Item of expenses	unit of measurement	Unit price	165m2 horizontally		130m2 on walls
			Consumption	Amount, rub.	Consumption	Amount, rub.
Liquid rubber	1 barrel	24000 rub.	4	96.000	3	72.000
Calcium chloride	1 kg	75 rub.	16	1.200	12	900
diesel fuel	1l	35 rub.	20	700	20	700
Delivery of barrels to the object	1 Gazelle walker	3000 rub.	1	3.000	1	3.000
Fuel for your car	1 trip	650 rub.	3	1.950	3	1.950
Unexpected expenses		5000 rub.		5.000		5.000
		Total expenses		107.850		83.550
		Paid by customer		136.950		110.500
		Profit		29.100		26.950
		Profit per square		177		207

At first glance, not so much, but the scope of work is small. There will be more square meters - there will be more profit. In total, we get earnings (or savings, if done for ourselves) on one house 56,050 rubles.

Each time it will take approximately 5 hours to deploy and prepare the equipment, apply liquid rubber, roll up the equipment, load it into the car.

Thus, 1 sq.m., on average, allows you to make a profit of 56050 / 295 = 190 rubles.

Now you can estimate how many square meters are required to pay for the installation.

* From 01-04-2014 to 31-03-2015

After the price of the equipment is "recaptured", you begin to receive a net profit in the amount of 190 rubles from each sq.m. You will make 1000m2, therefore you will earn 190,000 rubles.

Is it possible to increase profit from the square?

It is important to understand that in this example, the profit per square meter for waterproofing walls is higher, because. the actual consumption per square is less than when applying liquid rubber on the horizon. In this case, it is 4.6 kg versus 4.85 kg, which gives 30 rubles. additionally on each square.

Profit increases if the consumption of liquid rubber is reduced, and hence the thickness, and hence the reliability and durability.

For example, if in the first case, not 4 barrels, but 3 are brought to the facility, then the return from the square becomes not 190, but 335 rubles. On each of the 165 squares, we will receive an additional profit of 145 rubles, due to an unused barrel, which costs 24,000 rubles. Consumption per 1 m2 in this case will be 3.6 kg, which corresponds to a coating thickness of 2.5 mm. In principle, this is acceptable, but already on the verge.

The payback period of equipment with such profitability is significantly reduced. It will turn out to zero for an electrical installation at 220V after 106200/335 = 317m2.

106200/354 \u003d 300 rubles / m2, the amount that should remain from each square.

For the example under consideration, the profitability per 1 m2 along the horizon is 177 rubles. Then you can calculate how much emulsion you need to "not put" in order to get an additional 123 rubles / m2. One kilogram, i.e. the actual consumption should not be 4.85 kg, but 3.85 kg, which is quite acceptable.

Therefore, in order to recoup the installation of Technoprok E-22 in 354 m2, the consumption of liquid rubber should be 3.85 kg/m2, at a price of 830 rubles per 1 m2 of finished coating.

Entrepreneurs are attracted to brand new liquid rubber waterproofing business low initial investment and high profitability. Despite the fact that the direction is new and still little mastered, today more and more entrepreneurs are interested in this business.

It consists in the offer of waterproofing with liquid rubber of various construction projects. True, in Russia today small business has some difficulties with implementation. There are several reasons for this:

1. High level of competition.
2. Serious starting investments.
3. Intricacy, complexity and imperfection of the legislative system, which is designed to regulate the sphere of small business in the country
4. High taxes.

Taxes and legislation is an issue that only state bodies can decide. Therefore, changes in this area should not be expected, at least in the next couple of years. The entrepreneur will have to adapt his business idea to existing requirements. It can only affect start-up capital and the level of competition. But how to do this, let's try to discuss further.

Waterproofing with liquid rubber

The business idea is attractive because this highly profitable business does not have high competition. To start a business on waterproofing with liquid rubber, investments will require approximately 150 thousand rubles. And the services consist in carrying out waterproofing with liquid rubber of various buildings and premises for legal entities and individuals.

What is the uniqueness of the phenomenon

This newest material is based on bituminous material, which is suitable for construction work. It can be used in waterproofing almost any material. Waterproofing with liquid rubber applied in the following areas:

Roofs and other building structures;
pools;
cellars;
artificial reservoirs;
foundations of residential buildings.

Before the previously popular insulating materials (rizolin, roofing felt, etc.), waterproofing with liquid rubber is much more attractive in price. In addition, it allows for seamless insulation. In the case of roof waterproofing with liquid rubber, this is a guarantee of reliable protection against water and leaks.

Such rubber can be used on any material. It adheres well to materials of any texture, age, geometric shape, hardening stage. As a rule, joints and seams are connected, a monolithic membrane is created, which creates an ideal waterproofing.

The main advantages of the material

Serves up to 25 years.
Repairable.
Environmentally friendly technology, no solvents are used.
Resistant to large and sudden temperature changes.
The elasticity index is 1000%.
Excellent soundproof properties.
There are no air cushions between the rubber and the coating surface.
The application is cold, fast, seamless.
Can be used on wet surfaces.
Hardens within 5-30 seconds.
A layer of 0.25-4 mm thick is applied in one pass.

Equipment for waterproofing with liquid rubber

To create a liquid rubber waterproofing business, you need to purchase special liquid rubber waterproofing equipment.

1. Special protective equipment for each employee: to protect shoes, skin, respiratory tract.

2. Spray guns are the main equipment used to spray liquid rubber.

Installations for waterproofing with liquid rubber on the market are presented in a rich assortment. The difference between the installations lies in the power, the manufacturer. This also affects the price of the equipment. For example, an imported unit will cost more than a domestic one by about 80-100 thousand rubles.

However, if you want to purchase an imported installation, you must be ready to constantly purchase imported consumables. Such units will not work on domestic rubber. Therefore, it will be cheaper and more reliable option when waterproofing of roofs with liquid rubber will be carried out on domestic equipment.

Business Economic Calculation

Waterproofing roofs with liquid rubber requires certain costs. These include:

1. Starting capital at the first stage:

Purchase of components and raw materials, that is, directly liquid rubber and coagulant. For 200 kg of liquid rubber, 25 kg of coagulant is required. This purchase will require 20 thousand rubles from you.
Working inventory, which includes fluids for flushing equipment, as well as various solution storage tanks. This will require about a thousand rubles.
Remedies. For a thousand rubles, you can buy a light set of protection for shoes, skin and respiratory tract.
Purchase, delivery, installation and debugging of the line will result in 100 thousand rubles.

2. Additional costs:

Registration of activities in the tax and other authorities usually costs at least 12 thousand rubles.
Delivery of raw materials costs an average of 8 thousand rubles.

In total, to start such a business, you will need at least 14 thousand rubles. initial investment.

Business Profitability

Now we propose to calculate what profitability of roof waterproofing with liquid rubber. If we sum up all related expenses, as well as the estimated income from activities, it turns out that you can get 70 thousand rubles per month. Two orders is about 500 square meters of finished surface. With such a workload and income, investments will return in about two months. That's why liquid rubber waterproofing business is considered a profitable and highly profitable business.

About what liquid rubber is, what it consists of and where it is used, you can watch the video:

Water, where it should be - in a bath, bathhouse, river or sea, not only pleases the eye, but invigorates and amuses any person. But water, where it should not be, can become a source of a big problem. We are talking about metal corrosion, a leaking lid or a wet basement. And then the water turns into an enemy, which must be stopped at any cost. Therefore, the waterproofing business will always be in demand.

There are many waterproofing products on the market with various unique properties, designed for self-use or professional use. Household waterproofing products do not withstand any comparative competition with professional ones, so there is only one way to make money on them - by selling these products. If you are planning to start a professional waterproofing business, then you need the appropriate funds. Today, the leaders in this market of services are - liquid rubber and polyurea. Let's consider each method separately.

Features of the liquid rubber waterproofing business

Liquid rubber, polymer material based on bitumen. In fact, the material is not rubber in chemical composition, however, performance properties similar to rubber underlie the name.

"Liquid rubber" or CBS mastic is a one- or two-component bitumen-latex water emulsion modified with various polymers.

Liquid rubber is used for external waterproofing of roofs, basements, metal structures, swimming pools and other facilities where waterproofing is required. Such a composition is applied using conventional hand tools - a roller, brush, spatula. Or with the help of special spray equipment, in this case, CBS mastic is supplied with a coagulant (an aqueous solution of calcium chloride) from a two-nozzle sprayer. The coagulant flows off the surface, and the mastic polymerizes almost instantly. You can use this coating 2 hours after application.

The disadvantages of this material are: instability under UV radiation, low mechanical wear resistance, subject to destruction in aggressive environments (solvents, gasoline, brake fluid). Therefore, "liquid rubber" is additionally protected with a second layer, for example, paint from UV rays.

Key advantages of the material and equipment features- low cost (compared to polyurea). Spraying equipment and raw materials are produced by various enterprises in Russia, so starting in this type of business costs no more than 150 thousand rubles. Of these, a special installation costs 50-100 thousand, and 50 thousand will be spent on business registration and the purchase of raw materials (at the rate of 100 rubles per 1 kg of mastic). You can also reduce costs and apply liquid rubber manually, which will affect the timing of the work, but entry into such a business will cost only 30-50 thousand rubles.

The cost of waterproofing with liquid rubber is from 700 rubles per square meter. A team of 2 people can cope with the work. So, equipment manufacturers claim that rubber can be sprayed on 1000 square meters in 8 hours, that is, in 1 working day. Mostly, this service is used by private clients.

Polyurea waterproofing business

Polyurea (polyuria, polyurea)- a synthetic material created using chemical reactions based on natural elements. When applied, it forms an extremely durable and highly elastic seamless layer. The tensile strength of such a film is more than 35 MPa. The strength of the material is not inferior to ceramic tiles.

The key feature of this material- high waterproofing properties, chemical and mechanical resistance, under ultraviolet rays the mixture only changes color. The material is practically indifferent to the temperature of the treated surface, since the polymerization is carried out by means of a special catalyst. Also, the material acts as an excellent dielectric. When properly applied, the service life of the coating reaches 20 years.

To work with this material, special equipment is required - equipment (reactor) for polyurea and polyurethane foam, as well as the so-called components - “liquid A and B”. The reactor is responsible for heating, dosing and injection, and the mixtures are mixed immediately before spraying.

Disadvantages of Polyurea Business- high cost of components and equipment, and application of the material is impossible without equipment. Since, as a rule, all the production of the most installations or components in this business area is concentrated abroad (Europe, USA, China). Therefore, the initial cost of equipment is quite high - from 250 thousand for the initial set. The raw materials are also expensive. The total cost of entering the business can reach up to 1 million rubles.

Additionally, with the help of this equipment it is possible to spray polyurethane foam (PPU) insulation.

However, the superiority of polyurea as a waterproofing material makes such a business very popular, even compared to liquid rubber. The cost of application per 1 square meter is from 1500 rubles. The high cost of such a roof is offset by a long overhaul period, so, already in the third year of operation of the roof without repair, the cost of applying (taking into account the savings on repairs) is reduced to 1000 rubles. Ease of installation also ensures high productivity - up to 500 square meters per working day. Mostly, this service is used by large clients - management companies (flat roofs of houses, waterproofing of basements and ceilings), enterprises (roofing of workshops, electromechanical protection of equipment) and so on.
