DLT GEOCELDA is a three-dimensional mesh to stabilize soil and slopes. Its structure is made of high-density polyethylene (HDPE) stabilized for UV radiation that is used to confine aggregate, gravel or soil to increase the soil bearing capacity or to control erosion on slopes. The sheets may be perforated to increase drainage.

The use of geocells provides a stable surface for both pedestrian and vehicle traffic areas (paths, parking lots, golf courses, etc.).
