IMPTREX DRAINBOARD DIMPLEBOARD

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 8 mm dimple configuration
  • Compressive strength of 25 m²
  • 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
