NPS Geofoam vs. Traditional Materials

Traditional earth materials are heavy, cause settlement, instability and/or lateral pressures. Alternative lightweight fill materials such as foamed concrete, waste tires, soil, woodchips and wood fiber have higher densities, are variable in their makeup and are not engineered, due to field execution variables.
