To waterproof basement walls, apply a high-quality waterproof paint like DRYLOK White Extreme Waterproofer to the interior of the walls. This product comes premixed and is applied like a coat of paint, filling all surface holes and allowing it to dry completely before applying a second coat. A 5-gallon container covers about 500 square feet of wall.

Do not apply sealer over painted walls or efflorescence. If you or a previous owner painted the basement walls, remove the paint before applying sealer, which only adheres well to bare masonry. Effluence, or white deposits on concrete walls subject to constant moisture, should also be removed before applying sealer with muriatic acid.

To keep water away from your basement, remove foundation plantings and flowerbeds that require watering, inspect and repair gutters and downspouts, and grade your yard away from the foundation at a minimum of a 2 percent slope. Consider having an exterior drain tile system installed, which can cost $10, 000 or more and requires excavating soil around the outside of the basement to install a perforated drain at the footing level. A waterproof membrane is often installed on the outside of the basement wall, and a buried sump pump is pumped to the surface.

Additionally, consider installing a drainage channel beneath the floor inside the basement. This drain is similar to the exterior drain tile but located just inside the basement walls. New walls are built on the inside of the drain, preventing residual water from seeping through the old basement walls. This job is typically done by a foundation contractor and costs around $5, 000.
