Dimple Board/Drainage Sheet is a cuspated protection sheet made of High-Density Polyethylene HDPE. It is a lightweight, Ƃexible, strong, durable, non-toxic, dimpled sheet board with 8mm deep dimples. It is impermeable to water and water vapor. It is fixed to the walls and roofs of structures to provide a filtered drainage plane that routes groundwater and gases away from the structure. It is best used as protection for a sheetwithout membrane against physical damage from backfill operations.

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.
