Sheet Drain
Prefabricated drainage composite used behind walls and beneath slabs to relieve hydrostatic pressure.
- Relieves hydrostatic pressure against foundation walls
- Combines drainage core with geotextile filter fabric
- Simplifies installation compared to aggregate drainage systems
产品介绍
Sheet Drain
A prefabricated drainage composite: a dimpled or cuspated core that creates a flow channel, bonded to a geotextile filter. It replaces a traditional aggregate drainage layer in a fraction of the thickness, which matters where excavation width behind a wall is limited.
Strengths
- Replaces an aggregate drainage layer in far less thickness
- Core maintains flow capacity under backfill load
- Bonded geotextile filter keeps the core from clogging
- Fast to install — no aggregate handling
Function
- Drainage
- Filtration
- Hydrostatic pressure relief
Applications
- Retaining and basement wall drainage
- Beneath slabs and plaza decks
- Landfill cap and base drainage layers
