SUPERSEAL Dimpled Membrane – Foundation Waterproofing & Drainage Protection

SUPERSEAL Dimpled Membrane is a long-lasting, high-performance waterproofing and drainage barrier made from durable HDPE plastic. For over 25 years, contractors across North America have trusted it to protect foundations from moisture, backfill pressure, and costly water intrusion.

This mechanically fastened membrane is ideal for all types of foundations—including poured concrete, concrete block, ICF (Insulated Concrete Form), and interior drainage systems. It can be installed on the interior or exterior of the foundation and backfilled immediately after installation.

The unique dimpled design creates a continuous air gap that relieves 100% of hydrostatic pressure from the wall. This space lets moisture condensate outward onto the membrane surface, where gravity drains it down to the footing drain. It also acts as a protective barrier, preventing backfill or sharp materials from contacting the wall or damaging waterproof coatings.

With 60% of foundations cracking within the first year, SUPERSEAL's flexible air-gap system allows the foundation to shift, crack, and settle—without compromising its performance. Backed by a 40-year product warranty, it's a smart, proven solution for long-term protection.
