FIELD: construction. ^ SUBSTANCE: sliding support for concrete slab, preferably for foundation slab; sliding support contains the first and the second films at that the first film contacts base of foundation concrete slab and the second film contacts concrete at lower part of foundation slab and both films are in tight contact with each other. Between films there is at least one layer of permeable gas or liquid and/or flat textile, fabric or knitted material. ^ EFFECT: strength improvement, reduction of friction forces between slab and base, reduction in specific consumption of materials. ^ 26 cl, 3 dwg |
