Delta-MS Waterproofing Membrane

DELTA®-MS is a highly effective waterproofing membrane on masonry and poured concrete foundations. It is a protective system based on a uniquely formed air-gap membrane that isolates the backfill from the foundation. This unique design allows any water getting past the dimpled plastic sheet to fall freely to the footer drain.

Benefits/Advantages

  • Eliminates damp, leaky basements.
  • Reduces musty odors, mold and mildew.
  • Environmentally friendly.
  • Increases your home’s value.
  • Requires no maintenance.
  • Unaffected by freeze thaw cycles.
  • Available in large sheets, thereby minimizing seams.
  • Keeps soil moisture from touching the wall, condenses and drains construction moisture to the footing drains.
  • High-density polyethylene is impermeable to water and water vapor.

 

Function

The membrane’s key job, the first principle of fail safe water management, is to keep water from ever touching the wall on its way through the soil to the footing drainage systems.

DELTA®-MS provides two lines of defense. The first is an impermeable plastic sheet that is waterproof. The second is the dimpled structure that offers a free drainage path. In the event that water passes the first line of defense, it can flow freely down the air-gap to the footer drain. Unlike a coating, DELTA®-MS bridges all size cracks, ignores damage points, and deflects water as well as soil dampness. It also allows for the drainage of construction moisture to the footer drain.

An insulation board is recommended as a valuable add-on to the DELTA®-MS system. The insulation board helps protect the DELTA®-MS membrane from any damage when backfilling. In addition, the insulation board’s excellent insulating characteristics, high resistance to water and water vapor-superior compressive strength and long-term durability resists moisture to deliver a stable R*-value over the long term.

*R means resistance to heat flow. The higher the R-value, the greater the insulating power.
