Abstract: A composition for and method of sealing cracks in concrete in the absence or presence of water is disclosed, where the composition includes at least one acrylate monomer having acrylate groups and at least one curing agent capable of cross-linking acrylate groups, the curing agent being capable of cross-linking the acrylate groups in the presence of water to form a cross-linked acrylate compound. The method for sealing a crack in concrete includes the steps of blending at least one acrylate monomer having acrylate groups with at least one curing agent adapted to cross-link the acrylate groups to form a mixtures providing covering means to cover the crack to be sealed and applying the mixture under the covering means within the crack before the mixture cures.
