Abstract
A method for making an expansion wall is provided. The method can include applying a matrix to a first ply and applying an expansion element to the surface of the matrix. A second ply is applied over the first ply to trap the matrix and expansion element therebetween. The applied expansion element is entrained into the applied matrix to provide an expansion material that is configured to expand to, and solidify in, an expanded condition upon activation.
