Sprayed waterproofing is used for installation of traditional and inverted types of roofs. Applications include repairing old coatings, protecting against rust concrete structures and metal structures of any complexity.

Spray-on liquid waterproofing provides maximum protection against UV rays. Even if the previous coating is coarse or aged, the substance binds to its base at the molecular level, forming a kind of welding with the material. No other analog can boast of such special qualities.

Building material advantages

The application of waterproofing using the cold spray method can significantly speed up the process. Other benefits include:

1. High level of adhesion to the surface.
2. Fast polymerization.
3. The elasticity of the building material.
4. Moisture resistance, ultraviolet radiation and low temperatures - up to 50 degrees below zero.
5. The ability to reflect UV rays without heating the roof.

We offer to buy liquid sprayed waterproofing in any volume. The manufacturer's warranty is valid.

Subtleties of roofing

Applying liquid insulation speeds up work - an area of ​​up to 1,000 m 2 can be treated per day. The process is carried out in several stages:

1. The surface is prepared, primed.
2. The actual application of liquid rubber takes place.

To put waterproofing, use an ordinary roller. For large volumes, it is recommended to use devices with high pressure that work like sprayers. This method is often used for old roofs that are impossible or expensive to dismantle.

The cost of building materials

The price of liquid sprayed waterproofing depends on the following factors:

• properties (resistance to temperature changes, level of elasticity);
• method of application;
• manufacturer.

Types of roadway waterproofing

For waterproofing the road surface, you can use different materials... All of them have their own advantages and disadvantages, as well as limitations in their use. The choice must be guided not only by favorable price, but also by the peculiarities of working with certain compositions, ease of installation, and so on.

Among the most commonly used waterproofing:

• Bulk is the most old way isolation. New types of bitumen are capable of forming an impermeable film that will not let water into the asphalt. It is also one of the cheapest methods.
• Fusion-bonded - roll membranes and other materials are used here. They provide a continuous water-repellent layer. However, they are quite difficult to install.
• Sprayed is the most technologically advanced way to protect the canvas. Usually, mixtures of latex and bitumen are used for this.
• Penetrating - asphalt treatment special composition, which penetrates into its thickness and fills the pores. Above usually requires an additional device of sprayed or welded film

They are united by practicality, durability and excellent performance.

Technologies for waterproofing the roadway of pavements and road surfaces changed a lot for last years... Increased requirements for the quality of waterproofing road pavement and its durability, served as a serious impetus towards use.

To fill expansion joints of concrete pavements under construction, depending on the category of the road and the road-climatic zone, it is recommended to use polymer-bitumen sealants. In each case, the properties of these materials must be checked before use. Polymer sealants are also recommended for filling seams in concrete surfaces of airfields.

DIRECTIONS FOR USE

• Sealing works should be carried out at an air temperature of at least 5 ° C and in the absence of atmospheric precipitation.
• Before sealing, expansion joints must be cleaned of old sealing material, dirt, dust. Sand, rubble, foreign objects, products compressed air and dried.
• For creating good contact between the sealants and the end surfaces of the joint, it is necessary to treat with a primer. The primer is applied in one layer using a spray gun or brush.
• When applying the primer, care must be taken to keep the bottom of the expansion joint and the surface of the coating along the joint clean.
• Sealing of expansion joints MBR-G90, MBP-G90 is carried out after the primer has dried.
• Heating up of sealants should be carried out in a special boiler (melting plant) with a jacket filled with a heat carrier with a high boiling point and equipped with forced mixing and thermal control systems.
• Heating temperature of sealants (operating temperature) (180-200) ° С.
• The residence time of the sealants at operating temperature after melting should not exceed 2 hours.
• Heating the sealants to a temperature of more than 200 ° C and reheating leads to the loss of the sealants of their operational properties.
• Expansion joints should be sealed with a special joint filler.
• It is allowed to use non-serial devices for sealing joints, provided for by the technical and technological documentation of the manufacturer of sealing expansion joints.
• The temperature of the sealant in the boiler of the filling unit must be constantly monitored.
• Sealing of expansion joints should be carried out in such a way that it is not necessary to remove excess sealant that has gone beyond the seam, since when removed, the adhesion of the sealant to the walls of the joint may be broken.
• To ensure this, the sealing of the seams MBR-G90, MBP-G90 should be carried out flush with the edges of the expansion joint of the coating.
• If the level of the sealant in the expansion joint after cooling and shrinkage is exceeded, the sealant must be cut off with a sharp heated scraper or other similar device the excess sealant protruding above the joint, as well as the sealant that has got on the coating, without breaking the adhesion of the sealant to the end surfaces of the seam.
• Spreading of sealed expansion joints with fractionated sand or mineral powder is allowed.
• During the production of works on sealing expansion joints, movement is unacceptable Vehicle on prepared for sealing and freshly sealed expansion joints.

Sealing of expansion joints must be carried out in strict compliance with safety requirements.

Waterproofing of roads is made to increase the wear resistance of the roadway, prolong operational period, before renovation works... When laying as the base of a roadbed reinforced concrete slabs, the waterproofing coating increases the elasticity, wear resistance of the concrete roadbed, and also prevents crumbling of concrete and reinforced concrete slabs under the influence of atmospheric precipitation (snow, water).

Also, waterproofing reduces the destructive effect of mechanical stress, the effects of chemical liquids and reagents on concrete plates roadbed.

The process technology is simple. A bituminous or bitumen-polymer composition is poured onto a prepared and cleaned concrete bed. Due to its fluidity, it penetrates well into all joints, cracks, creating a waterproofing layer. Bituminous - polymer compositions are preferable, as they allow you to process large area with less material consumption.

There are several types of roadway waterproofing.

Bulk method the most simple and in the recent past the most common. Its main advantage is the low cost of the work carried out. At the same time, the good fluidity of bitumen grades B4 and B5 made it possible to obtain good quality waterproofing. The disadvantage of this method is that to warm up the bitumen composition, special boilers, which had to be constantly kept under high temperature. To this can be added the high flammability of the work carried out and low speed road construction.

Fusion bonded waterproofing method(membrane fusion) consists in the fact that a roll of solid material prepared on the basis of bitumen is laid on a concrete surface. In some types, the edges of the rolls have a bonding composition, for better connection and ease of styling. The material is overlapped. Then the flooring is treated with a directed high-temperature jet. open flame... A single waterproofing membrane is formed.

Sprayable waterproofing of roads Is the most advanced technology to date. Under high pressure, a bitumen-latex composition, 4-6 mm thick, is sprayed onto concrete slabs. Latex does not allow the emulsion to spread over the web. In air, the bitumen-latex emulsion quickly solidifies, forming a uniform coating. The advantage of this method is that it does not require the use of high temperatures... The most homogeneous waterproofing membrane is formed. This method the most environmentally friendly, safe, economical in energy consumption.

Penetrating waterproofing they are used, as a rule, for the welded and sprayed waterproofing method. Its essence is in the use of synthetic compounds that fill all the cracks and voids in concrete pavement roads. When water enters, the composition expands, filling all the voids. Then the membrane is fused or sprayed on. Today it is the most reliable and durable waterproofing. Manufacturers, as a rule, keep the composition secret. The composition itself also gives additional strength. concrete base roads. Such compositions are used for roads with a strategic direction, routes with increased load and requiring high degree security.
