Interior Basement Waterproofing

INTERIOR BASEMENT WATERPROOFING

Basement Waterproofing

In many homes across North America, foundations have cracked or are just old and the exterior waterproofing has failed. It can be extremely costly to excavate these homes to repair the walls properly.

Without proper exterior foundation waterproofing solutions, stopping water from entering your home is extremely difficult. BUT you can control it.

Installing SUPERSEAL Dimpled Membrane as a part of an interior basement waterproofing system, permanently diverts water and moisture to your sump pump.

Not only does this keep water out of your home it also protects your insulation from getting wet. Just 7% moisture in your insulation can reduce the thermal efficiency of your insulation by up to 70% in that area. Proper installation of an interior basement waterproofing is the solution to protecting your home and helping to guarantee a dry basement.

Products required

Preparing the Wall

Dig / jackhammer a trench around the perimeter and install a drain pipe and sump pump. Ensure that your pump drains properly.

Fill the trench with quality drain store. Install SUPERSEAL Dimpled Membrane to the top of the wall. Fold it 6” to 12” onto the stone.

Fill in with concrete and let cure.

Frame your walls and install flooring as required.

SUPERSEAL Installation

Unroll the membrane at your marked grade height. Ideally the top of the wall or 3” to 6” above the exterior grade height. (where the dirt comes to on the wall.)

Keeping the membrane tight against the wall and using 1 ¼” concrete nails or concrete screws, install install a row of Small Plugs or Super Plugs at the top of the membrane.
Space them approximately 5’ apart.

Overlap any vertical seams by 6” and install plugs along the seam.

Install a row of plugs at the bottom of the membrane just before you fold it onto the drain stone.

For rolls over 6’7”, install an additional row of plugs along the middle of the membrane.
