What material is used for road waterproofing. Materials for waterproofing road surfaces: buy, catalog, units, prices. Other waterproofing materials for roads and bridges

On device pavement use bitumen roll materials, bitumen-polymer sealants and mastics, polymer membranes. Their main difference from waterproofing roofing materials and materials for waterproofing foundations - this is a higher requirement for the quality of the material, and the difference is in the type of dressing.

Rolled bituminous materials for road waterproofing:

Type - 1 (SBS modified, cold styling) - these are bituminous materials with the addition of SBS (styrene-butadiene-styrene) modifier, these materials when laying in pavement require an additional concrete protective layer or are used when laying cold asphalt concrete mix. This type includes materials of the type Technoelastmost B, Mostoizol 100.

Type - 2 (APS modified, hot laying)- these are bituminous roll materials with the addition of APO (alpha polyolefins) modifier, which allows you to lay the asphalt concrete mixture directly on the hydro insulating material. This type includes the following materials: Technoelastmost C, Mostoplast, Mostoizol 130, Mostoizol 140.

Other materials for waterproofing roads and bridges:

Bentonite mats are also widely used in sealing road surfaces and airfields. This material consists of bentonite granules located between geotextile sheets. The main advantage of this material over others waterproofing materials in that, when punctured, the bentonite mat is self-healing. This is due to the properties of bentonite clay, which expands when water hits the clay and forms a waterproof gel. Bentonite mats are laid between layers of pavement under weight.

Road waterproofing is one of the most important measures in the laying of roads. new road or laying an asphalt layer on a repaired one. Waterproofing is used for:
1. Ensuring a long period of operation of the road surface.
2. Increasing the strength and elasticity of reinforced concrete pavement.
3. Increase the wear resistance of concrete slabs, reduce their crumbling under the influence harmful conditions environment.
Since roads are one of the busiest transport lines, the requirements for their quality should be as high as possible. A bunch of transport companies, for example, the freight dispatcher of PKF Agro-Naberezhnye Chelny LLC, which is professionally engaged in the transportation of goods on the roads of our country, knows firsthand that moisture is one of the main enemies of modern asphalt. At the same time, road waterproofing can significantly improve the quality of the roadway, reduce the risk of its destruction in the most loaded places.

Road waterproofing technology.

1. Concrete slabs are laid on the prepared base.
2. Shed the slabs with bituminous or bitumen-polymer waterproofing materials. The latter method is preferable, as it allows you to capture large area with less material consumption.
3. Lay the asphalt layer.
The apparent simplicity of this technology is deceptive. In fact, it is necessary to take into account the thickness of the welded or sprayed waterproofing, its ability to penetrate into the joints of concrete slabs. In addition to waterproofing the asphalt layer, it is additionally possible to carry out waterproofing of concrete slabs. First of all, it will protect the road from the damaging effects ground water. In combination with drainage systems, concrete waterproofing gives a noticeable increase in the service life of a reinforced concrete road.

Types of road waterproofing and their scope.

1. Bulk. Most often, bituminous compositions are used as a material for pouring. A fairly common method of waterproofing roads in the recent past. Its main advantage is relatively low cost and good penetrating power. The disadvantages are expressed in the need for constant heating, the use of a digester. This significantly slows down waterproofing roads, leads to excessive consumption of electricity and additional labor costs.
2. Built-up waterproofing of roads. Its basis is rolls of waterproofing solid material stacked overlapping each other. Sometimes rolls are equipped with special coupling edges, for greater ease of installation. After roll material laid on the required area it is melted with a jet of an open flame high temperature. As a result, the joints and seams are firmly fused to each other, forming the so-called membrane. This membrane protects the roadway from water, solutions of alkalis and acids of medium concentration.
3. Sprayable waterproofing of roads. Recently, it is becoming more and more widespread as a high-tech means of waterproofing. The basis of such insulation is a bitumen-latex emulsion mixed with air in a special apparatus. Under high pressure, this mixture is sprayed onto the surface of the roadway. Unlike pouring with bitumen, this method is much more environmentally friendly and safer - the use of road waterproofing does not require its heating. As a result, the cost of electricity and expensive equipment is reduced. The use of sprayed waterproofing of roads allows you to create the most uniform and durable membrane. Its thickness is maintained within 4-6 mm, depending on the operating conditions of the roadway. Unlike bituminous insulation, this waterproofing of roads allows you to fully protect both vertical and horizontal surfaces with high efficiency. Waterproofing material does not run off vertical surfaces, thanks to the latex base, almost instantly hardening in the air. Thus, the process of drying the roadway is simplified, the time of this process is reduced.
4. Penetrating waterproofing of roads. Often, along with welded or sprayed waterproofing, waterproofing is used that penetrates into the structure. concrete base. The principle of its action is based on special components that expand and harden when water enters. As a rule, manufacturing companies hide the "recipe" of such compounds. Such waterproofing of roads can not only fully protect concrete slab from moisture penetration, but also to increase its strength by filling the voids that certainly occur when pouring concrete. Such protection is well suited for the average amount of groundwater or additional load on the road from the side of the roadway.
In Russian conditions, penetrating waterproofing is expensively used on roads of high importance, as well as in areas with difficult climatic conditions. Road waterproofing must be carried out using quality materials, since the resistance to loads of the entire roadway depends on its strength.

The problem of road waterproofing is acute in most of Russia. Roads must be built in accordance with all technical requirements. The stages of road construction include the application of a leveling layer, such as gravel, the waterproofing of the layers, and the direct surface of the road, usually asphalt. All steps are important, but special role plays road waterproofing.

Road waterproofing

Proper waterproofing of roads will ensure long-term operation of the roadway. Optimal material for waterproofing is a geomembrane. It meets all the requirements that road waterproofing puts forward. This is a roll material that has very high strength and elasticity.

In the absence of a waterproofing layer, freezing water leads to soil pressure on the surface layer of the roadway, destroys it, falling into small cracks. Even in the absence of frost, the accumulated volumes of water have a strong impact on the surface and other layers of the road. If good road waterproofing is installed, then water will not be able to penetrate through the geomembrane to the pavement. Thus, the construction of roads in areas with an unfavorable climate will not lead to their destruction.

The strength of the geomembrane allows it to withstand very strong loads. When elongated by 6-8 times, the geomembrane does not become unusable. Temperatures below 60 degrees are not terrible for her. So waterproofing roads with a geomembrane gives excellent results. In this case, it is necessary to observe the technology of laying this material.

Road waterproofing welding

Individual pieces of geomembrane are welded together. For this, special welders, allowing to achieve a perfect seam that will not let water through even under significant loads. Doing this work is very important, otherwise all the costs may not be justified. Our site presents the most modern devices for welding films. When using them, you can always get excellent result when waterproofing the road and it will last a long time.

Currently, sprayed waterproofing is gaining great popularity. This method of protecting buildings and structures from moisture has many positive qualities and does not require the dismantling of the old coating.

The composition of the sprayed waterproofing includes two components: a filler and a catalyst. Interacting with each other, they turn into a strong, seamless membrane. Such insulation is applied by cold spraying.

Most often, as a sprayed layer, " liquid rubber”, which is a bitumen-polymer or polyurethane composition.

Advantages and disadvantages of the method

The popularity of sprayed waterproofing is explained by its clear advantages over other types of building protection from moisture:

• ready waterproofing compound packaged in barrels that are easy to use and transport;
• the composition is applied by cold spraying, i.e. excludes the use of open fire, which is very important from the point of view of fire safety;
• when using "liquid rubber" there is no need to dismantle the old waterproofing. Besides given material has excellent adhesion to most building structures;
• "liquid rubber" forms an even, seamless film, regardless of the coverage area and object configuration;
• the insulation created by spraying retains its performance in any climatic conditions;
• sprayed protection layer is very durable, elastic, 100% waterproof. It is resistant to active water flows, does not exfoliate from the base, and is environmentally friendly. "Liquid rubber" can also be used as anti-corrosion protection metal elements building structures. Creation of a 2 mm layer of sprayed insulation replaces the 4th layer of traditional roll coating;
• the material does not age from temperature fluctuations, vibration and solar ultraviolet;
• there are no solvents in "liquid rubber". Therefore, it is completely environmentally friendly. Only water evaporates from it;
• it is economically profitable to organize the repair of a defective area by spraying, since this method does not require the dismantling of the damaged layer;
• the insulating material, when applied to the surface, fills all cracks and pores. Therefore, it is guaranteed to protect building structures from moisture, steam and gases.

When creating waterproofing by spraying, there is no need to use fixing material, nails, dowels, etc. This allows you to maintain the original integrity of the entire coating.

However, "liquid rubber" also has a number of negative qualities that must be taken into account when organizing protective waterproofing works:

1. The material may lose its performance under the influence of an aggressive environment (solvents, petroleum products, etc.).
2. It is possible to remove "liquid rubber" from the surface of the building material only mechanically.
3. The cost of the method is quite high. In addition, only experienced specialists can work with it, using specialized equipment.
4. Separate types sprayed waterproofing can lose their protective qualities under the influence of UV rays. Therefore, they require additional protection, for example, by painting.

Where is "liquid rubber" used?

The main scope of sprayed waterproofing is protection against moisture of foundations and roofs, load-bearing structures buildings and structures, as well as reservoirs. In addition, it is used:

• in shipbuilding, automotive and mechanical engineering to protect metals from corrosion;
• V civil engineering to protect against destruction concrete structures;
• during the construction of bridges, tunnels, strengthening of bulk slopes, etc.;
• for isolation of pipelines, capacities of water-pressure constructions, strengthening of irrigation canals.

Varieties of sprayed material

"Liquid rubber" can be of two types: single-component and multi-component. A single-component composition is already ready for direct use, and a multi-component composition is prepared before starting work and consists of a base and a catalyst.

"Liquid rubber" according to the method of application can be divided into:

• bulk;
• painting;
• for cold spraying.

It is the last group that is most in demand when creating waterproofing.

Technology of application of "liquid rubber"

Waterproofing works using sprayed materials are organized in the following order:

1. The protective composition is applied in strips no more than 1.5 meters wide. The material must be applied evenly. The presence of untreated areas is not allowed. There is absolutely no need to flat surface. The main thing is that there are no foreign inclusions and defects in the resulting film. For spraying, it is best to use devices operating under high pressure.
2. Before processing sharp corners, reinforcing material is laid on them. For example, non-woven geotextiles.
3. If a multicomponent composition is used, then it must be borne in mind that it almost instantly hardens on the surface.
4. If spraying is carried out on a concrete roof, then the thickness of the protective layer must be at least 2 mm, on metal surface- not less than 1 mm, on brickwork- 1.5 mm.

Protection of building structures from moisture by spraying a waterproofing layer is new way organization of such work, which requires a special approach.
