FIELD: chemistry.
SUBSTANCE: present invention relates to compositions used to produce (meth)acrylic hydrogels. Present invention also relates to a method of producing hydrogels and injection materials from said compositions and to a method of sealing and/or filling cracks, cavities, defects and cavities in construction industry. Described is a single- or multi-component composition for producing a hydrogel which contains a system of radically polymerizable monomers or prepolymers, free-radical polymerisation initiator and, optionally, a catalyst for said initiator. System of radically polymerizable monomers or prepolymers contains a liquid at room temperature water-soluble (meth)acrylic compound, applied on at least one solid carrier and/or solid or liquid at room temperature water-soluble (meth)acrylic compound, dissolved in aqueous solution, wherein said aqueous solution is applied on at least one solid carrier. Sum of water-soluble (meth)acrylic compounds is 10.0–95.0 wt % with respect to the total weight of the mono- or multicomponent composition.
EFFECT: technical result is improvement of physical properties of hydrogel.
