EPS (expanded polystyrene) is tailor-made for a variety of applications in construction including, but not limited to, residential and commercial building, roadway and foundation stabilization, and a wide range of other custom solutions. Geofoam blocks, used as ultra-lightweight fill below highways, parking lots and embankments take advantage of EPS’ properties of light weight, easy installation, durability and resistance to rot, mold and mildew. EPS is the most cost-effective insulation material, whose R-value does not decrease with age. When it comes to your next construction project, expect nothing less than perfect. Trust no one other than Plymouth Foam.
