Abstract
A method utilizing non-reactive fillers in the sealing of unstable rock strata under wet or humid conditions, the method comprising providing (a) from about 10 to about 85% by weight of a water soluble alkali metal silicate, (b) about 0.7% to about 10.0% by weight of a water soluble or water miscible reactant for said alkali metal silicate and (c) about 2 to about 50% by weight of non-reactive filler, bringing components (a), (b) and (c) together with sufficient mixing to form a sealing composition, applying the composition in a coating to the rock strata and permitting the composition to set while being exposed to wet or humid conditions to form an impervious sealant coating thereby imparting structural strength and reinforcement and preventing penetration of air and dust through the rock strata. Preferably the non-reactive filler comprises a minor proportion, for example from about 0.2% to about 10% by weight based on the weight of the sealant composition of reinforcing fibers.
