Damp-proofing Membrane

DMX FlexSheet™

The New Standard in Air-Gap Membrane

Keeps your basement dry, comfortable and livable

FEATURES AND BENEFITS

DMX FlexSheet™ - higher quality and greater value.

Here are just some of the many benefits and advantages you will get when you use DMX FlexSheet™ on your project.

• DMX FlexSheet™ resists potential damage during backfill. Made from High Density Polyethylene (HDPE), a tough durable material, DMX FlexSheet™ does not require the special protection boards many other products do.
• Install and backfill the same day. You can install DMX FlexSheet™ as soon as the forms are removed. No waiting for foundation walls to cure or dry.
• As the name implies, DMX FlexSheet™ stays flexible and easy-to-use in any weather. If you can take it, so can DMX FlexSheet™.
• DMX FlexSheet™ bridges even large foundation wall cracks that cause water damage, callbacks and unhappy homeowners. Our dimpled sheet provides a protective air gap that keeps water out the crack, unlike tar-based products.
• New walls are full of moisture. DMX FlexSheet™’s air gap technology allows moisture to exit the wall and work its way to the footing drain. Wet soil never touches the foundation. Walls dry properly so they are not damaged by freeze-thaw cycles.
• HDPE is safe and environmentally friendly. It won’t leach harmful chemicals into the soil around the home, as tar-based products may do.
• Because there are no harmful chemicals involved, you do not need special breathing and skin protection during installation. Just your usual: safety shoes, glasses and a hard hat.
• You get support from a company you can trust. At DMX, we are committed to providing outstanding service and superior products. Our goal is to make sure you never have a second thought about choosing DMX FlexSheet™.
  
   

Frequently Asked Questions about DMX FlexSheet™

How does water get into my basement?
Most 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 hydrostatic pressure against the wall that will push water into the basement, even through the tiniest crack. DMX FlexSheet™ isolates these cracks from the surrounding wet soil, to prevent this from happening.
 

How does DMX FlexSheet™ work?
DMX FlexSheet™ creates an air gap between wet soil and your basement wall, allowing the concrete to breathe and disperse moisture. Wet soil never touches the wall next to your living space.
 

Why does DMX FlexSheet™ have dimples?
The dimples in DMX FlexSheet™ create an air gap that eliminates the hydrostatic load (pressure) that forces water into the foundation.
 

Can water get behind DMX FlexSheet™?
In most cases - NO. However, even if the sheet was damaged and water got behind it, the air gap would prevent water from getting into the home. Because there is no direct soil pressure on the wall, water just drips down to the footing and away through the drainage system.
 

Do I need special fasteners to install DMX FlexSheet™?
You will need DMX FlexPlugs and plastic washers for attaching the membrane to the foundation. Use with 1 ¼ inch concrete nails for poured or concrete block foundations, and 1 ½ inch deck or drywall 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 windows or on a slope.

What types of foundation can I use DMX FlexSheet™ on?
Every type you can think of—poured concrete, Insulated Concrete Forms (ICF), block wall, and wood.
 

Can I use DMX FlexSheet™ for repairs and renovations?
Absolutely! DMX FlexSheet™ 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 FlexSheet™?
Yes! We suggest installing an extra row of DMX FlexPlugs to help stand up to the pressure heavy clay can exert on the wall.
 

Is DMX FlexSheet™ just for walls?
Not at all! You can use DMX FlexSheet™ for subfloors, exterior wall protection, interior wall repairs, built-up flower beds, retaining wall protection, around culverts, and many other commercial or industrial applications. Keep watching as we come up with even more!
