DELTA® Terrax is a dimpled sheet with a geotextile layer which acts as a surface layer. Normally used as a green roof external drainage layer, it also protects the primary waterproofing applied to substrate. Laminated on to the dimpled sheet, a layer of compression-resistant permanent filtration geotextile prevents the dimple structure from being clogged up by sludge, guaranteeing optimum long-term drainage.
Terrax is an external membrane that can be used vertically and horizontally.
The membrane has an adhesive tape manufactured on one side to overlap and join to the next part of membrane.
