Lightweight radon- and moisture-proof building foundation comprises a finely profiled thin plate (C) whose upper side is provided with an upper sealing layer (A) of elastic, gas-tight polymer concrete or the like, by means of an intermediate bonding layer (B) of moisture-proof, self-adhesive material such as polymerised bitumen, asphalt or the like. The underside (C) is provided with a water-repellant, thermal insulation layer of expanded cellular plastic supported by a thin gas-tight layer (D) of polymerised concrete. |
