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.
