Dimple Sheet (12mm) With 150gsm Geotextile - Retaining Wall Drainage | 1m x 15m
Dimple drainage sheets are designed for horizontal and vertical drainage on retaining walls, basements, roof slabs, planters, parking decks, foundations, and tunnels. The dimpled core creates a continuous drainage path to relieve hydrostatic pressure and help structures dry out. Install with the geotextile facing the soil and the dimples against the wall. For wider coverage, press dimples together along edges or butt sheets edge-to-edge and secure with reinforced tape.
