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.
- 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 CONCRETE OR CINDER BLOCKS
- 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.
HOW DOES WATER GET INTO MY BASEMENT?
Most poured concrete basements have cracks of some kind that occur during the curing process. This is very common at window openings, beam pockets, and sometimes at corners or elevation changes.
When the soil around the foundation gets wet, it creates a constant hydro-static pressure against the wall that will push water into the basement, even through the tiniest crack.
Moisture can also get into basements through capillary action which acts like a sponge and draws water from areas of high concentrations (exterior soils) to areas of low concentrations (interior basement walls), especially in the presence of minimal foundation protection.
DMX AG™ isolates these cracks and capillaries from the surrounding wet soil to prevent this from happening, and provides a clear negative side drainage path for ground moisture to be redirected to the footing drains, eliminating lateral water flow into the basement.
HOW DOES DMX AG™ WORK?
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?
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™?
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
DO I NEED SPECIAL FASTENERS TO INSTALL DMX AG™?
You will need DMX Washers™ for attaching the membrane to the foundation.
Use the 1¼ inch concrete nails for poured concrete foundations and 1½ inch coated deck screws for ICF foundations.
DMX FlexTrim™ is available for sealing cut edges in the membrane where the flat panel has had to be trimmed off, such as around basement below grade windows or along the top of the membrane on a slope.

ON WHICH TYPES OF FOUNDATION CAN I USE DMX AG™
Every type you can think of – poured concrete, insulated concrete forms (ICF), and wood foundations.
CAN I USE DMX AG™ FOR REPAIRS AND RENOVATIONS?
Absolutely! DMX AG™ will protect everything from a modest crack in a residential foundation, to the stone foundations of century-old churches and homes.
WE HAVE HEAVY CLAY SOIL. CAN WE USE DMX AG™?
Yes! We suggest installing an extra row of DMX Washers™ in the body of the DMX AG™ to help stand up to the vertical pressure heavy clay soil can exert on the membrane and the wall (see our installation manual for details).
