FIELD: construction.
SUBSTANCE: invention relates to the construction, in particular to a multi-layer protective panel and a system for basement walls, intended for thermal insulation, drainage, protection against water and ventilation on the outer surface of the walls in contact with the ground. Multi-layer protective panel for basement walls, which is a composite panel, combines various functions, such as thermal insulation and drainage from the outside, and contains the following layers, which are previously connected to each other as an element for subsequent assembly. First layer of insulation type in accordance with the back surface, namely, facing the wall, consists of a rigid XPS plate, having a thickness of between 20 mm and 200 mm, with a side tongue for alignment between adjacent panels. Second layer of drainage type consists of a waterproof embossed membrane made of HDPE, characterized by a small thickness, which is attached to the first layer mentioned by means of protrusions or hillocks facing the ground. Third layer of the filtering type consists of permeable geotextile, which is attached in front, namely to the heads of the above-mentioned tubercles, to form a drainage space in accordance with the front surface, namely facing the ground, the said third layer borders as a edge a rigid insulating layer for its partial overlap during continuous filtration. First layer of XPS material is characterized by a back surface, provided with a plurality of ventilation ducts parallel to each other and arranged vertically along the entire height, namely from the lower edge to the upper edge, to be located in direct contact with the outer surface of said wall, namely on the outer surface, creating a space for transpiration. Second and third layers attached to each other with the same dimensions as a drainage and flexible membrane, characterized by a width (L) equal to the width of the first layer mentioned, namely, they are aligned in the lateral direction and, on the other hand, are characterized by a greater length relative to it, fringing the top and bottom to form the upper edge and lower edge, respectively, so as to move the water down in a continuous vertical drainage over the entire height, namely from the height near the ground level and to the base of the wall, where the placement of perforated longitudinal drainage pipe is provided. Mentioned upper edge protrudes at least for 15 cm from the top edge of the first layer and to the prescribed level of the ground to connect and protect the front from backfilling and from water. Lower edge is extended downwards by at least 20 cm from the lower edge of the first layer and to the prescribed drainage depth to allow for partial reversing of the said perforated pipe to the rear, by directly moving all the water vertically drained from the panel into the perforated pipe, while also integrating a geotextile filter pocket for the said perforated pipe from the front, open bottom and partially superimposed on said third layer in accordance with said lower edge, welded to the upper edge and protruding from below to enable partial wrap in front of said perforated pipe and for connection to the bottom in combination with said lower edge, draining overlying soil in the gravel location. First XPS insulating layer is characterized by a continuous tongue-and-groove dowel on two opposite vertical sides for high lateral waterproofing between adjacent panels. Protective panel is made with the possibility at the same time: insulation, drainage, protection from water and mechanical loads, as well as providing the possibility of ventilation mentioned wall on the outer surface.
EFFECT: technical result consists in providing effective and simultaneous thermal insulation, waterproofing and ventilation of the basement wall, reducing the material intensity and labor-intensiveness of the construction.
