DMX AG™ Foundation Wrap2023-09-08T05:03:15+00:00

DMX AG Foundation Wrap

DMX uses a specially formulated 100% Virgin Polyethylene that provides a high environmental stress crack resistance to alkalies and acids found in the soil. Our special extrusion process utilizes low heat and low shear to prevent heat degradation in the final product. The use of antioxidants and lubricants further ensure a smooth, superior quality membrane that outperforms the competition.


The following is an overview of the types of constructions that will utilize the unique and effective moisture control attributes of our residential and light commercial product lines.

These membranes are designed to control moisture that effect concrete foundations. Our membranes provide the ultimate moisture protection with ease of installation.

Applications: Foundations

  • Residential foundation walls
  • Light commercial foundations (less than 15’ in height)
  • Golf clubhouse and athletic complex foundation protection
  • Single level underground parking structure
  • ICF (residential), wood, concrete, specialty foundations
  • NOT RECOMMENDED FOR USE WITH CONCRETE BLOCK WALLS, unless the walls are completely waterproofed prior to installation of the foundation wrap

Specialty Applications

  • Underslab moisture barrier
  • Crawl spaces
  • Concrete top side retrofits for finishing basements into living space
  • Landscape drainage for residential settings
  • Drainage and ventilation between built-up residential roof decks
  • Protection of liquid-applied waterproofing products in non-hydrostatic soils conditions

DMX Membranes manufactures a full line of accessory products to aid in the installation of the DMX AG™. These accessories withstand the rigors of the construction site.

  • 2” diameter round Attachment Washers for finishing off the top flat tab of AG
  • 2” wide DMX Flex Trim for finishing off vertical terminations of the membrane

  • 1.25” long Anodized Steel Nails for securing the round wastners
  • Power Actuated Installation* Nail Guns for attaching the membrane to the substrate


HOW DOES DMX AG™ WORK?2023-08-25T00:15:29+00:00

DMX AG™ creates an air gap between wet soil and your basement wall, allowing the poured concrete walls to breathe. It also provides a clear negative side drainage path to disperse any ground moisture that might find its way behind the membrane. Wet soil never touches the wall next to your living space, thus reducing the chances of water infiltration into the basement.

The DMX AG™ is made of HDPE which is an impermeable material to water. When installed according to our installation guide, it keeps water exterior to the foundation walls.

This means dryer basements for the end user, and a wider choice of finishing materials for completing a basement area.

WHY DOES DMX AG™ HAVE DIMPLES?2023-08-25T00:15:30+00:00

The dimples in DMX AG™ create a negative side air gap that eliminates the hydrostatic load (pressure) that can push water into the foundation, via cracks and capillaries as discussed earlier.

Without the dimples in DMX AG™ the product would be in direct contact with the foundation exterior, minus a negative side clear drainage path that could potentially trap moisture against the wall should it get behind the membrane and force water intrusion into the basement.

The key to DMX AG™’s success is the dimple design for the control of hydrostatic pressure and ground moisture control.

CAN WATER GET BEHIND DMX AG™?2023-08-25T00:15:31+00:00

In most cases this is highly unlikely when installed properly. However, even if the sheet was damaged and water got behind it, the air gap would prevent water from getting into the home by diffusing hydrostatic pressure build-up and providing a drainage path to the footing tile.

Because there is no direct soil contact with the wall, water just drains down to the footing and away through the drainage system.

The configuration of the dimple structure allows for continuous flow of water along the path of dimples and air gap to the footing drain and resists the transport of drainage water to the foundation wall.

The “conical” shape of the dimple provides a low resistance to vertical water flow and minimizes lateral movement of water, providing maximum protection of the foundation wall from moisture contact with the wall.
