Why would I use a subfloor membrane?

When finishing your basement it is important to consider the type of flooring material that you would use. Concrete floors typically have moisture within them or have moisture that can transfer through the concrete from the soil below the slab. This can come from cracks, shrinkage around the perimeter, or perimeter walls that have signs of weeping or leaks. If you install new flooring without a subfloor, the moisture can be absorbed directly into your new flooring. By installing SUPERSEAL Dimpled Subfloor Membrane, you will be lifting your new floor off the cold damp concrete. The dimples in the membrane provide an air gap, which allows small amounts of moisture to dissipate from within the air gap space.

What kind of flooring can I install on the membrane?

The Laminate & Carpet Subfloor Membrane – can be used with almost all types of flooring.

All-In-One Subfloor – can be used with interlocking laminate, engineered wood, and imitation tile.

Warm & Quiet – Can be used with 12mm or ½ inch laminate and engineered wood. In addition, by adding plywood to the top of the membrane you can install carpet and and various other types of flooring.

What is the warranty?

20 years against rot and break down.

How do you join the seams?

You use the SUPERSEAL Subfloor Tape. Unroll the membrane, butt the seams together and tape.

Do I need to use your tape?

SUPERSEAL’s Subfloor Tape is design specifically for the membrane and is part of the warranty. If you an alternative tape, it must be moisture proof.
