The invention is directed to a single- or multiple-component composition, which forms upon mixing with water a (meth)acrylic hydrogel and which composition comprises 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. The invention is also directed to a method for producing a hydrogel, to a hydrogel, to an acrylic injection material and to a method for sealing cracks, voids, flaws and cavities in building structures. |
