When making a blind area, first of all, it is necessary to remove the Turn and tamp the soil around the house. After that, fall asleep into the formed niche with layers of clay, sand and crushed stone to the required level. When installing the blind area, it is necessary to observe the slope angle away from the house. It should be at least 8-10 mm per half a meter of width. The dimensions of the coating are determined according to the size of the cornice of the roof and should be at least 20 cm wider than it. The next important touch is the creation of a compensation seam. It will preserve the base and blind area in the case of various deformations from destruction. For this day, they make a gap up to 1.5 cm wide and fill it with bitumen, a mixture of sand and gravel, or two layers of roofing material. A cement screed is laid on the prepared “pie”, making additional deformation seams every 2-3 meters, or another coating. Swigs must be made around the perimeter.
