Delta MS


Delta®-MS



DELTA®-MS is a dimpled membrane, impermeable to water and water vapor. The vacuum formed exclusive dimple pattern creates an air-gap between the membrane and the foundation wall. This unique design allows any incidental water getting past the dimpled membrane to flow freely to the perimeter footing drain. The air-gap guarantees a safe separation and full capillary break between the foundation wall and any ground-moisture.

Unlike any spray-applied coating, DELTA®-MS bridges large cracks and imperfections in foundation walls. This product can also be utilized as an effective protection layer over spray or sheet applied waterproofing systems.

DELTA®-MS is available in many sizes to cover any foundation with a minimum of overlaps and seams. The high compressive strength of the membrane is achieved due to a special dimple design and pattern, and ensures sustainable protection of foundation walls up to 12 ft below grade.


DELTA®-MS is manufactured with an exclusive co-extrusion process, utilizing 60% recycled High Density Polyethylene (HDPE) from municipal recycling programs in the middle, and two thin layers of a specific grade of virgin HDPE on the outside. We use this process, exclusive to the dimple sheet industry, because we respect nature and for environmental protection, as well as our strong commitment to sustainability of our products.

The encapsulation of the recycled HDPE ensures that DELTA®-MS is adequately protected against polymer degradation caused by oxidation and environmental influences like acidic soils or alkalinity (concrete), which all-recycle based products are highly vulnerable to. In fact, it is virtually impossible to control the environmental stress crack resistance (ESCR) of HDPE membranes that are made entirely from recycled resin.



DELTA®-MS, equipped with highly effective additive packages, is stabilized against oxidation and provides outstanding compressive strength, impact resistance, chemical and environmenta l stress crack resistance. Tests performed by independent and accredited laboratories prove the unrivaled sustainability and long-term performance, and are available upon request.

DELTA®-MS is easily installed by unrolling the membrane against the foundation wall. DELTA® Accessories allow for quick and effective fastening of the membrane. The top-edge of the product is sealed and protected against intrusion of soil particles or surface water with sealant and specifically designed profiles.
