DELTA-GEO-DRAIN dimpled sheeting also offers a solution to another problem: more and more frequently thick, soft elastic coating is used for the waterproofing of structures. On the one hand they are very reliable in bridging over cracks, but on the other hand they are very susceptible to damage and cannot be point-loaded in the long term DELTA-GEO-DRAIN acts as a protection and drainage system which can be laid in one operation, especially for use with thick coating but also with the waterproofing of structures with

plastic membranes. DELTA-GEO-DRAIN reaches the same values as DELTA-GEO-DRAIN TP regarding compressive strength and water conductive capacity. However, DELTA-GEO-DRAIN has in addition a slip-layer membrane spot

welded to the rear. This prevents a displacement and damage to the thick coating in the event of settlement of the backfill. If there is an intensive connection to the thick coating, it also acts as an additional waterproofing membrane.
