Self-leveling roof

Self-leveling roof is very popular in roofing industrial enterprises and economic structures. Let it not differ in special beauty, but practical and reliable. Device bulk roof has significantly more advantages than disadvantages.

The essence of technology

Bulk roof is a coating without seams. The structure of such a roof includes layers that are characterized by reinforcing and waterproofing properties. The reinforcement layer consists of materials that include fiberglass. The waterproofing component includes polymer and mastic materials based on bitumen. In this regard, the liquid roof have another name - mastic.

• Mastics are applied on reinforced concrete plates, cement-sand screed, wood, metal, flat slate and other surfaces. A layer of paint is applied on top of the roofing surface, which increases the reflectivity of the surface.
• Fill the roof satisfied by pouring a liquid mixture consisting of different amounts of components. After that, waiting for some time so that the surface becomes uniform and takes on the appearance of rubber. This protective material is not affected by aggressive media, ultraviolet radiation and temperature surges. In addition, the mastic roof is characterized by vapor permeability and good performance characteristics in different climatic zones.
• The bulk roof after curing becomes elastic, acquires excellent waterproofing properties that do not change with large temperature differences - from -50 to +120? C. Finished roof has high strength and wear resistance.
• Mastic roofs are widely used in roofing industrial plants. This is due to the high degree of mechanization of work. In turn, this leads to low labor costs, which are reduced by an order of magnitude compared to other technologies.
• The significant advantages of the bulk roof include the absence of seams on the surface. On the other hand, when covering a large area of ​​the roof, it is difficult to achieve the formation of a roofing layer of the same thickness. If necessary, you can reinforce the mastic waterproofing layer with a special mesh, which is usually made of fiberglass.

Note! Works on the construction of the bulk roof can not be carried out if the base of the roof is damp.

Applicable materials

Depending on the value of the slope of the roof, the technology of the self-leveling roof device has differences that can be divided into groups. Polymer roof or mastic differ in this case by the components that complement the materials of the layers.

• If the roof is almost flat and the slope does not exceed 2.5 ?, labor costs are significantly reduced during the work. This can be explained by the fact that hot mastic does not flow down an inclined plane - it means that there is no need to reinforce the bulk roof.
• When the slope of the slope to 25? to arrange this roof without reinforcement is no longer possible. Reinforced material in this case is needed to create a barrier that will prevent the free flow of hot mastic in one direction.
• If the slope of the slope on the roof exceeds 25 ?, then there is no point in carrying out work to create a mastic roof - the final result will not be a high-quality coating.

Depending on a design, a bulk roof happens with reinforcing, without reinforcing or in combined. All technological varieties are similar in one — first, a hot layer is applied onto the prepared substrate by spraying, which is protective. After an elastic film with waterproof characteristics is formed on the surface, the further construction of the roof continues, depending on the production technology.

• To increase the life of the roof with reinforcement, the inner layers of the compositions of polymers and bitumen are fastened with materials that include fiberglass, it can be fiberglass or glass fiber.
• At the device of a bulk roof, which is not reinforced, continuous waterproofing of the roof is obtained by applying EGIK emulsion to the surface. Then several mastic moisture-proof interlayers are applied, giving a total layer up to 1 cm thick. Then the coating on top is sprinkled with a crumb of stone or small gravel fraction.
• If a self-leveling roof is created by the combined technology, rolled waterproofing materials and mastic layers are superimposed on the surface in turn. The layers below are made of inexpensive, practical materials, and the top is passed with mastic, over which gravel reinforcement of the small fraction is carried out or water-resistant paint is painted.

Features of the device

Self-leveling roofs are most often arranged on roofs made of reinforced concrete plates, which have a smooth surface. Sometimes masters prefer to primed the surface with a cement-sand mortar. To improve adhesion, bitumen is dissolved in kerosene before being applied to the finished substrate. Then they pass over the surface with hot mastic, a layer of which is supplemented with fine gravel or crumb. Before you apply the next layer, you need to wait for the previous one to harden. Mastic layers are obtained with a thickness of approximately 2 mm and, depending on which technology is chosen, they are reinforced or left without a surface.

Coating materials are made on the basis of bitumen mastic, which may include different components. For example, they can be with or without coagulators. In addition, asbestos may be part of the bitumen mastic. Work on the installation of the bulk roof should be started from the gouge and the installation sites of the water receiving funnels.
