HDPE Dimple Drain Board for EArthwork Waterproofing

About HDPE Dimple Drain Board for EArthwork Waterproofing

91 000 74051  Dimple Board and high density Polyethylene (HDPE) Dimpled board. It is light weight, flexible, Strong, durable, Non-toxic, dimpled sheet board with dimple height of 08mm. It is impermeable to water and water vapour. It is used for protecting the water Proofing Membrane in basement walls.

Advanced Drainage Performance

Engineered with 8mm raised dimples, this board achieves superior water flow (>2.5 liters/m/s under 20 kPa), channeling moisture away and minimizing hydrostatic pressure. It safeguards waterproofing layers against potential water ingress, making it an excellent choice for earthworks and subsurface applications.


Exceptional Durability and Chemical Resistance

Manufactured from high-density polyethylene, the board withstands harsh underground environments. It remains stable and damage-resistant when exposed to acids, alkalis, salts, temperature variations from -30C to 120C, and prolonged UV exposure, ensuring long-lasting performance for over fifty years.


Effortless Installation and Versatile Application

The HDPE Dimple Drain Board is conveniently lightweight (approx. 900 g/m2) and available in rolls (2m x 20m). Installation involves unrolling the board and placing it directly above the waterproofing membrane, making the process efficient and adaptable to various project sizes and requirements.
