Dimpled Membrane

         Demonstrating market leadership in the growing movement towards product transparency and health in the built environment, DELTA®-MS is a below-grade dimpled membrane that has obtained a Red List Free Declare label with the Living Building Challenge (LBC) International Living Future Institute™.

         DELTA-MS, known for its durability and industry-leading performance, was introduced to the North American market more than 20 years ago.  Now, the dimpled membrane is in full compliance with the highest level of LBC criteria, helping architects and builders better meet advancing building codes and green building practices.  While there are countless steps you can take to make homes more energy efficient, starting from the ground up is the best approach.

         To ensure building materials perform properly and maintain their R-value, basements and crawl spaces need to be well protected with durable foundation protection products that help keep the below-grade building envelope and structural components dry.  Wet components, whether insulation, wood, or concrete, cannot provide the necessary insulation to keep heat and energy from escaping.  Choosing DELTA-MS will ensure a basement stays dry, which is good not just for the environment, but for homeowners as well.  More specifically, it is net-zero and high-performance-home compliant.

         DELTA-MS provides reliable protection for permanently dry basements, keeping moisture away from foundation walls.  Air-gap Technology allows incidental moisture that does get past, to drain harmlessly to the footing drain.  DELTA-MS keeps protecting even when concrete foundation walls crack, something asphaltic damp-proofing sprays can’t do.

         Made from 60% recycled and 40% virgin materials, the membrane’s co-extrusion process and offset dimples create higher compressive strength and impact resistance, ensuring its performance and protection last longer, especially when compared to other membranes typically made from 100% recycled materials or sprays.  DELTA-MS is 100% recyclable at the end of its life cycle.
