FIELD: construction.
SUBSTANCE: invention relates to the field of construction, namely, to a rough floor cover assembled from finished assembled elements, having adhesive elements and elements for control, designed for levelling of the cover relative to the covered area. The rough raised floor cover comprises a panel made of a polymer sand composite containing quarry sand, secondary ground polymer, a reinforcing fibre, a dye, a lightweight filler at a certain ratio of components. The panel may be made in the form of a polygon with a flat upper surface and a lower one, having a meshed structure, control elements. Ends of the polygon of the panel are equipped at all sides by stepped edges. Stiffening ribs on the inner surface are made in the form of polygons equipped with diagonals. At the same time in crossing points there are holes drilled, in which there is an inner thread cut.
EFFECT: higher strength characteristics of a coating.
