DRAINAGEBOARDS

DREXFOL drainage boards are dimpled sheets made of high-density polyethylene (HDPE), developed specifically for the waterproofing of building foundations and structures and for protection against ground moisture. The dimpled design creates an air gap between the sealed surface and the soil, so that draining water is carried away freely while also ventilating the structure.

Our product family ranges from the lighter DREXFOL 400 for use beneath the base slab to the extremely high-compression DREXFOL 1200, so the right load capacity is available for every project. The higher-grade types (800, 1000, 1200) perform well in civil engineering and high-load applications thanks to their outstanding compressive strength, while the perforated surface of the DREXFOL 1000 20P is ideal for inverted roofs requiring controlled water drainage.

The drainage boards protect the sealing layer from mechanical damage caused by backfill and debris, significantly extending the lifespan of the building structure. Our products are made from environmentally friendly material, resist chemicals, fungi and bacteria found in the soil, and are designed for a lifespan of at least 50 years. A downloadable technical data sheet (TDS) is provided for every type.
