Tough Layers for Trusted Protection.
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.

Dimple Board should be fixed for vertical application on the wall, ensuring the bubbles face towards the wall. A minimum overlap of 10 cm should be maintained between the sheets. Overlaps can be sealed with glue-insulated tapes. In the case of horizontal application,Dimple Board will be laid with bubbles facing the ground and an overlap of 10 cm between the sheets. Overlaps can be further reinforced with glue-insulated tapes.
• Rolls must not be exposed directly to UV radiation for over a month.
• Rolls must be stored in their original package horizontally under cool and dry condition.
• Rolls should be protected from direct sunlight, rain, etc.
