Composite drainage for lost shuttering

Some geocomposite drainage products may be used as lost shuttering also.
The drainage composites which have a cement milk-proof layer on one side, made of PVC layer (nonwoven coated with a PP film) could be used for lost shuttering.

Application
1 side PVC geocomposite drains can be used as lost shuttering when installed against the foundation wall of the adjacent building, a bored pile wall, a vertical excavation face or a rock face, permitting to cast the fresh concrete immediately against the drain.
