Geocells

Geocells are engineered for protection and stabilization applications. They are often used to help improve the performance of standard construction materials and erosion-control treatments. Geocell products are three-dimensional, expandable panels made from high-density polyethylene (HDPE), polyester or another polymer material. When expanded during installation, the interconnected strips form the walls of a flexible, three-dimensional cellular …
