Belgium Material

It is needed when working in the winter on the new concrete cover, humidity which bring to the regulatory parameters is impossible. In applying the 'breathing' roof in mass construction necessary for the project of roof design scheme of the device roofs showing layout of the layers and structures of nodes and adjacencies. Partial attaching the roof to the ground can be achieved by applying the lower layer: the perforated material, the usual material, pasted mastic as a uniformly distributed spots, continuous or broken bands mastics surfaced material that has surfaced bottom layer applied to the canvas by broken bands of 'breathable roof' has been successfully applied in Scandinavia, Germany, Belgium and other countries. When laying the material by or to meet technology needs to pay attention to the fact that he had a sufficient thickness of the lower cladding layer. The minimum thickness shall conform to the size of the irregularities (roughness) screed base.

Very tech devices from the roof membrane materials with an adhesive layer. Such a method may apply to both new roofs and repair old ones, but the base should be prepared with great care. To date, these materials are rather a rarity in the Russian market and apply is very limited. Roofing mastic of bitumen-polymer and polymer mastic can be applied to various surfaces (steel, concrete, asphalt) of any, even the most complex configuration (pitch, which laid mastic are not limited to, down to the domes and steeples). But there is one important condition: the surface must be perfectly flat, otherwise it will be impossible to achieve the same thickness mastic cover. This The biggest drawback mastics. Mastic is applied to the base in liquid form. After solvent evaporation, it solidifies, forming a continuous seamless waterproof film.

Thickness of the film depends on the number of solids in the mastic. In mastics, whose composition does not include a solvent, curing occurs without reducing the thickness of the deposited composition. Pay attention to the fact that the roof slopes more than 12% and temperature Outside air above 25 C in the mastic is necessary to introduce special fillers, which increase the viscosity (thickening agents, cement, etc.) Modern types of cements do not require a protective layer, as dyed they have necessary decorative properties, and the material itself rather resistant to weathering. If you need to protect the roof from mechanical damage (traffic areas, installation of engineering equipment, etc.) a protective layer of gravel (10-20 mm), coarse sand (2-5 mm), small-sized asbestos or bitumen sheets, etc. The ideal protective layer is a river pebble. And yet. Do not trust the installation of a roof at random people. Trying to save money on the project, as the material and pay workers wrapped triple costs. This applies to any type of roofing. Criteria for selection of firms tend to: availability of licenses, warranties, contracts with timelines, readiness to conduct a preliminary study designs and in writing inform the customer about possible problems, a willingness to intermediate inspections and a high level of communication culture.
