Engineered with a permanent polypropylene mesh heat-welded to the surface, the Delta PT series is the ultimate dimple board for high-end membrane protection. This integrated mesh provides an immediate mechanical "key," allowing for the direct application of Australian renders and plasters without the need for bonding agents.

Specifically designed for backfill membrane protection, Delta PT serves two vital roles: it acts as a heavy-duty physical shield for primary waterproofing layers against mechanical damage and soil pressure, and it creates a continuous ventilated air gap to isolate internal finishes from damp or salt-contaminated masonry. Whether used as backfill membrane protection for new-build basements or as a remedial solution for salt-damp isolation in heritage restorations, Delta PT ensures a dry, professional, and long-lasting finish.

NOTE: We sell & recommend ONLY for membrane protection prior to backfill.
