Wallbarn - Model Protecto-Drain 8 -Roof and Structural Drainage
Suitable for subterranean foundation walls, tanking and basement construction. The 8mm deep cups provide an air gap between the concrete structure and the backfill. Water runs down the outer surface towards a drain at the bottom of the structure. Creates a permanent air gap when fixed to surface walls and floors, preventing hydrostatic pressure and helping to ventilate the structural wall.
- Made from high density polyethylene (HDPE)
- Lightweight, flexible and durable
- Protects waterproofing membranes from abrasion or puncture
- Dimpled “egg-box” profile giving high compression strength
- High tearing and impact resistant
- Rot-proof, safe for drinking water
- Available in two size Rolls – 1 x 20m (20sqm) & 2 x 20m (40sqm)
- Nails pass through the membrane and don’t split the material
- Plugs seal the cups
- A cover profile fitted at the top prevents particles dropping behind the membrane
- Sheets can be bonded to the structural wall using bitumen based adhesive tape or fixed with nails and plugs
- Each sheet must overlap each other by at least 20cm for secure installation
- Can be bonded together to create one seamless watertight layer
- Can be fitted to floors to act as a vapour barrier and a damp proof layer
When used in the correct manner and application, the material will be rot proof for 20 years. Wallbarn application rules and proper site storage, handling and installation practices must be carried out as a prerequisite for any possible future warranty claims.
