Abstract: A hydrogel forming composition comprising at least one water-soluble (meth)acrylic compound, at least one free radical initiator, at least one catalyst for free radical formation, and water, wherein the at least one catalyst for free radical formation is an amine compound of formula (I). The invention is also directed to a multiple-component composition, to a hydrogel, to use of the hydrogel forming composition for sealing of constructions, tunnels, or mines or for soil stabilization, to a method for sealing and/or filling of cracks, voids, flaws and cavities in a building structure, and to a use of at least one tertiary amine compound for reducing the gelling time of a hydrogel forming mixture.

Abstract: A single- or multiple-component composition, which forms upon mixing with water a (meth)acrylic hydrogel and which composition including at least one water soluble at room temperature liquid (meth)acrylic compound supported on a solid carrier and/or an aqueous solution of at least one at room temperature solid or liquid (meth)acrylic compound, a free-radical initiator, and optionally a catalyst for the initiator. A method produces a hydrogel. An acrylic injection material. A method seals cracks, voids, flaws and cavities in building structures.
