Abstract
Pieces of strips of flexible, open plastics mesh structure are randomly embedded in a matrix without creating a substantial amount of extra void space in the matrix, to strengthen the matrix. Each piece or strip comprises more than one mesh opening, has tenaceous junctions or intersections, has high dimensional stability in its plane, and has high flexural recovery. Relatively small, generally flat pieces can be used, or alternatively strips more than one hundred times as long as they are wide. In the case of soil, a special machine can be provided which cuts up a reel of continuous mesh structure and has a rotary digging tool which digs up the top layer of soil and mixes pieces with the soil.
