IMPTREX - Drainboard
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.
- Ground slabs.
- Basement walls.
- Sportfields and gold courses.
- Chemical storage areas.
- A diagonal 8mm dimple configuration.
- Compressive strength of 25m2.
- Rolls may be joined by overlapping.
- Creation of efficient drainage and vapour barriers between diaphragms and internal walls.
- Wide, light weight rolls that allow rapid and low cost installation.
- Acting as a protection layer over waterproofing membranes.
- Replacement of lean concrete sub base slabs without compromising load bearing capacity.
