Interior Waterproofing

CAP Waterproofing & Drains the trusted go-to professionals when a time-sensitive problem arises.

Interior waterproofing is one of many sure ways to protect the one major investment in your life, your home. Interior water seepage and moisture in a home's foundation is a direct indication that there is a crack/leak which should be attended to as soon as possible before becoming a major problem for which exterior waterproofing and excavation would be required for a permanent fix.

Rain or snowmelts or rising water table which is found below the basement floor could be rising. In this case the drainage system located along the inside wall of your home will help dispurse water safely outside your home's interior and away from the foundation. It is best to contact the professionals at CAP Waterproofing & Drains to complete a comprehensive evaluation and provide a FREE QUOTE of the scope of work required.

Sump Pump & Interior Weeper

No problem with our innovative Interior Weeper & Sump Pump solutions.

This waterproofing method is used primarily on block foundations, or in Home Restoration projects where excavation is not an option. The Interior Weeper product is positioned below your flooring and above the home’s footings, allowing any water to penetrate through many relief holes. Water is then directed towards a Sump Pump and discharged to grade level outdoors, which will guarantee the relief of hydro static pressure on your foundations walls.
