The reinforced concrete floor slab with a slope -forming screed, a layer of insulation and waterproofing is a standard element of the structure of the operated roof. It is necessary to pay attention to the exact device of the drainage in any device of the operated roofs. To do this, on the surface of the roof, a screed with a slope along the top of the bearing plate is laid. The main waterproofing is installed according to the leveled sloping screed: polymer membrane, bitumen membrane, PVC membrane. Each and the listed materials have their own positive and negative qualities. General requirements include high elasticity. Above the average, there should be the level of resistance of mechanical influences, the ability to withstand offensive environments, as well as preserve their useful features of at least a quarter of a century. If you rent apartments for a long time in Donetsk, then you should first take care of their roofs so that they are strong and can withstand any weather.
The composition should not contain substances that include organic solvents in their composition: oil toluene, acetone and other other substances that contribute to the deformation of extruded polystyrene foam. Then you should approach the thermal insulation and waterproofing layers with all responsibility, it will be extremely important to calculate exactly the thickness of the layer. The temperature, as well as the formation of condensate on the ceiling, will depend on this, which in this case no one needs. For this reason, it is important to entrust the work of this kind to the designer with experience, the master of his business. The insulation in inversion roofs has contact with water constantly, this suggests that heater with a low percentage of waterwork should be used, less than half a percent in volume. The best of all is suitable for foamed glass or estrian polystyrene (EPPS). In these materials, the cellular structure is closed, so the moisture will not be absorbed, but the heat engineering qualities will remain throughout the entire period of operation of the roof.
