Basement Waterproofing questions, answered by experts

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.

Mold can grow anywhere in your home where there’s moisture that doesn’t dry out, usually in areas that are either not ventilated properly or where moisture gathers continuously. Insulation, drywall, and foundations typically provide mold with areas to grow if moisture is present and does not have a chance to dry out. Some of the most common areas in a home for mold growth include:

  • Attic

  • Walls

  • Bathroom

  • Crawlspace

  • Basement

Proper drainage prevents water damage, mold growth, and foundation settling, protecting your home’s structural integrity.

Yes, crawl spaces can attract bugs, especially since moisture tends to build up in the space, and moisture attracts pests. A good way to prevent pest infestation in your crawl space is to install a vapor barrier—called crawl space encapsulation—on the interior to seal the space, along with a French drain or some other kind of foundation drainage system outside to keep runoff out of your crawl space. You can also seal foundation cracks and repair damages to cut off access to pests.
