DELTA® Terraxx in walkable roofs  

 

DELTA Terraxx is a dimpled sheet which acts as a surface drainage layer. Laminated on to the dimpled sheet, a layer of compression-resistant permanent filtration geotextile prevents the dimple structure from being clogged up by sludge, thus guaranteeing optimum drainage in the long run. Terraxx is an external membrane that can be used vertically and horizontally.
