Abstract
Abstract Multiple sections of grid-like sheet material extend centrally through a thickness of a plurality of staggered rows of concrete panels to form a geomattress of unlimited dimensions. The sheet material preferably includes a plurality of parallel strands and perpendicular, intersecting bars. At least one bar extends within each concrete panel in a direction parallel to a longitudinal axis of the concrete panel to add strength to the formed geomattress and aid in lifting of the geomattress by the sheet material. The geomattress is formed by placing a section of sheet material above bottom mold halves filled with concrete and then filling top mold halves positioned above the sheet material with concrete. Gaps formed between adjacent rows of staggered panels and tapered sidewalls of the panels allow bending of the geomattress to aid in lifting the geomattress and to conform to a limited extent to the contour of the area onto which the geomattress is placed.
