The present invention relates to a method for making a sound-insulating load-bearing floor, said method comprising the following steps: applying a sound-insulating material over a loadÂbearing floor so as to form a continuous coating layer; allowing said continuous coating layer to harden; applying a covering floor over said hardened continuous coating layer; wherein said sound-insulating material includes: from 40% by weight to 95% by weight, preferably from 60% by weight to 90% by weight, with respect to the total weight of the sound-insulating material, of at least one rubber in a subdivided form; from 5% by weight to 60% by weight, preferably from 10% by weight to 40% 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 23°C, of from 0.1 Pa.s to 100 Pa.s, preferably of from 0.2 Pa.s to 50 Pa.s, more preferably of from 0.5 Pa.s to 20 Pa.s; a second component comprising at least one metal oxide or hydroxide. |
