Imptrex Drainboard is a modular sheet composed of high strength polyethalene (HDPE) of brown and black colour. Module height is 8 ±0.2mm. It is specially designed as drainage layer and for protection of underground walls. It acts as a barrier and provides protection to the waterproofing membrane from the backfill.
The dimples create a vapour and thermal insulation barrier in both internal walls adjacent to waterproofing membranes. Imptrex Drainboard offers protection against rising dam in ground slabs and without compromising the load bearing capacity of the sub base.
