Abstract: A multicomponent composition for filling and/or grouting cracks, flaws, and cavities in structures or earth and stone formations, including: i) water; ii) cement; iii) an aqueous plastic dispersion; and iv) at least one monomer, which can be radically polymerized, or a polyisocyanate. A material is thus obtained as a sealant having both a swelling capacity and expandability.

Abstract: A multicomponent composition for filling and/or grouting cracks, flaws, and cavities in structures or earth and stone formations, including: i) water; ii) cement; iii) an aqueous plastic dispersion; and iv) at least one monomer, which can be radically polymerized, or a polyisocyanate. A material is thus obtained as a sealant, which displays great adjustment capabilities of hardness and reaction time, in addition to its cost-effectiveness. Such a composition unifies positive properties of various materials as a sealant, such as expansion capacity and swelling capacity.
