Of all the variants of the landscaped roof roofs with herbal cover is the most simple and operation. Plants for her are selected the most unpretentious, for example, the devils that do not need fertilizers, watering and mowing. From the cereals recommended a field thin, mintalist meadow, oatmeal field and red.
For flat roofs with a lawn, a bias is optimal in 4-6, providing the natural flow of excess water. With a bias of more than 10, cellular lattices are used to disembark grass, in which plants root in the ground. We also use vegetable mats, or mats, well-retaining moisture and containing nutrients.
No matter how easy it was roofing with herbal cover, an additional load on the bearing elements of the structure it will create a lot. Therefore, first of all it is necessary to determine if your home will withstand. In calculations, not only the structural layers of the roof, but also the weight of the accumulated water, as well as the snow cover.
A lot of technologies for creating green roofs are invented abroad. Similarities are well known such systems from iOMREVL (Belgium), Index (Italy), Soprema (France) IDR. They are built on one principle. The roof is prepared as a multilayer pie consisting of a concrete base of a thickness of at least 50mm, waterproofing, insulation, geotextile, drainage layer, as well as fertile soil or substrate. A serious problem for green roofing is water, or rather, its lack or excess. Therefore, it is necessary to take care of a reliable drain-accumulative system, for the device of which gravel is most often used.
Let's try to figure out how the lawn is arranged on the upper terrace of our country house. The roof has a small bias for water drain. To form it, wooden substrates of different thicknesses were placed on the bearing antiseptic pine beams. The insulation of insulation was used polystyrene foam (100mm), preventing moisture condensation. Covering it with a polyethylene film, installed formwork from boards and cast a thin (70mm) concrete membrane, reinforced with a metal mesh, and a supernumbering screed; Three layers of waterproof and geocan were put on top. Then poured a layer of fertile soil (50mm) and a rolled lawn was mounted from the company "RusskiGazone". The drains were organized with a natural tumor, which laid the edges of the roof, putting on the bitumen mastic. On the gaps left between the plates, water flows into the gutter and further into the drainage Pipe.
