Delta ® MS

DELTA® -MS, commonly known as "The WRAP" is the premium choice in foundation protection. No other dampproofing product performs as well when it comes to keeping water out of your basement.

The DELTA®-MS membrane is extruded and vacuum formed from high density polyethylene (HDPE) a tough, durable, non-toxic material. The membrane is remarkably impermeable to water and water vapour and impervious to acids and other agents.

The dimpled design creates an air-gap between the damp soil and the foundation wall keeping moisture from ever touching the wall on its way to the footing drains. Unlike a coating, the membrane's design allows it to permanently bridge large cracks, tie holes and honeycombed or damaged sections of concrete.

The airspace also has the unique effect of allowing moisture from the concrete curing process to escape to the outside of the wall rather than to the interior of the foundation.

Installation is performed by certified professional installers and can be used on any foundation type, from poured concrete and block walls to pressure treated wood (PWF) and styrofoam formed foundations.

Even better, the DELTA® -MS membrane is backed by a 20-year product warranty and a 7-year leakage warranty, ensuring your peace of mind for years to come.

DELTA® -MS. Protect your foundation.
