A reinforcement laminate has been patented for reinforcing a substrate comprising a carrier layer. The carrier layer is made of a material selected from the group consisting of fiberglass cloth, metal screen and foil. A first layer of foamable material capable upon activation of becoming a rigid reinforcement foam is secured to the carrier layer. A second layer of foamable material capable upon activation of becoming a compliant foam is secured to the first foamable layer. The second foamable layer comprises a bonding layer for securing the laminate to a substrate. The first foamable layer and the second foamable layer is heat cured and foamed in-situ. The second foamable layer upon activation becomes a foam layer capable of absorbing shrinkage strains due to heat cure of the second foamable layer and cooling of the substrate. This layer includes a pattern of holes creating open passageways completely through the laminate.
