Patent ID: 7861484

Claim:
A method for making a sound-insulating load-bearing floor comprising: applying a sound-insulating material over a load-bearing floor so as to form a continuous coating layer; allowing said continuous coating layer to harden; and applying a covering floor over said hardened continuous coating layer, wherein said sound-insulating material comprises: 40% by weight to 95% by weight, with respect to the total weight of the sound-insulating material, of at least one rubber in a subdivided form; and 5% by weight to 60% by weight, with respect to the total weight of the sound-insulating material, of at least one binding agent comprising: a first component comprising at least one organic compound having at least one acid functional group or a derivative thereof, said first component having a Brookfield viscosity, measured at 23Â° C., of 0.1 to PaÂ·s to 100 PaÂ·s; and a second component comprising at least one metal oxide or hydroxide, wherein said sound-insulating material, after hardening, has a dynamic stiffness, measured according to standard ISO 9052-1:1989, lower than 300 MN/m 3 .
