SUPERSEAL Dimpled Membrane is commonly used for interior french drain applications in basements. It creates a permanent diversion of water to your sump pump completely protecting your home from common cracks or leaks.

Instead of excavating the outside you can also install SUPERSEAL Dimpled membrane on the inside. This type of application redirects incoming moisture and water directly to your drainage system.

NOTE: Just 7% moisture in your insulation could reduce the thermal efficiency in that area by up to 70%.

SUPERSEAL Dimpled Membrane is made from tough, long lasting plastic that keeps exterior moisture out. It bridges typical wall cracks with ease.

The dimples in the membrane create a drainage space that diverts incoming water to your sump pump or drainage system.

Why Choose SUPERSEAL Dimpled Membrane (SSDM)?

1. Consistent Basement Waterproofing Protection

SUPERSEAL Dimpled Membrane is very user friendly, easy to use and is made from a 24-mil high-density polyethylene plastic that provides consistent protection around your entire foundation. Other basement waterproofing products may require coating thickness measurements. SUPERSEAL Dimpled Membrane will always be the same thickness.

2. Fast Easy Installation

SUPERSEAL Dimpled Membrane is very tough yet flexable, and clean to work with. It wraps around and through corners with ease. You just unroll it, fasten it with common tools and backfill.

3. User Friendly , No Waiting

SUPERSEAL Dimpled Membrane starts working as soon as it is installed. There is no curing time or second coat needed such as with some other basement waterproofing products. SUPERSEAL Dimpled Membrane does not need to cure, dry or set. It provides your foundation immediate protection.

4. SUPERSEAL Dimpled Membrane Bridges Gaps and Normal Cracks

Being mechanically fastened to the wall, shifting and settlement cracks will not affect the membranes durability. A basement waterproofing solution for the entire foundation wall.

5. Drainage Space

SUPERSEAL’s basement waterproofing product does not allow exterior moisture to enter and allows interior moisture to escape. The dimples keep the backfilled soil away from the foundation wall, creating an air gap or drainage space. This drainage space allows internal moisture to condensate outward on to the membrane. By gravity, the moisture then falls to the drain tile for removal.

6. Long-Lasting Basement Waterproofing Product

Alkalines in concrete and soils can eat away at low-density plastic membranes and spray-on-coatings. This could cause these basement waterproofing products to degrade and dissipate into the soil in just a few short years. SUPERSEAL Dimpled Membrane is resistant to these environments and may last as long as the structure. Which basement waterproofing system would you want on your home?

7. Not Weather Dependent

SUPERSEAL Dimpled Membrane can be applied in most any weather condition. You do not have to wait for the concrete to cure or the weather to clear up. You will be able to work when your competition is stuck waiting for a better day. It is a one-trip basement waterproofing application.

8. SUPERSEAL's Basement Waterproofing System Eliminates Hydrostatic Head Water Pressure

Exterior water and soil rest against the membrane face and not the foundation face because of the air gap created by the membrane. This air gap eliminates headwater pressure buildup. Even in the event that the membaren has a hole in it, water pressure finds the air gap space and immediately falls to the footing drain for removal.

9. Environmentally Friendly

SUPERSEAL Dimpled Membrane is 100% environmentally friendly and safe. SUPERSEAL Dimpled Membrane does not emit any V.O.C’s, dissipate into the soil, affect streams, creeks or local wildlife. Builders, Basement Waterproofing Contractors and Do-it-yourselfers prefer SUPERSEAL Dimpled Membrane because it does not cause environmental concerns or problems with the EPA.
