Saturated soil, poor drainage, and cracked foundation walls can allow moisture into your basement. Over time, water seepage may cause rot in wooden building materials, promote the growth of mold, and even compromise the structural integrity of your home. Fortunately, basement waterproofing techniques can seal the gaps and prevent further damage to your foundation.

How Professionals Waterproof Your Basement

1. Clean the Affected Area

Basement waterproofing products will plug most cracks and holes, but they should be applied directly to the concrete. Before using sealers or other products, a technician will scrape off any paint and scrub away dirt with a brush and warm water. For the best adhesion possible, they'll need to let the surfaces dry completely before applying sealants.

2. Fill Large Gaps

Hydraulic cement creates a waterproof seal that is impervious to moisture, making it perfect for filling holes and large cracks in basement concrete. A professional will only mix what they need for each application since the cement will dry in 10 to 15 minutes.

3. Fix Small Cracks

Small cracks that spiderweb across the concrete are a common sign of water penetration. Masonry crack filler is typically sold in application bottles with small nozzles, which makes it easy to fill smaller cracks. Thankfully, professionals have the necessary tools for a clean job. 

4. Use Sealant Around Openings

The spaces around door and window frames also create small gaps that can allow water into the basement. Silicone sealants are flexible and waterproof, which makes them the best option for door and window frames.

5. Coat the Walls & Floor

Once obvious gaps and holes have been plugged, a technician will apply a waterproofing sealer to the entire concrete surface. These products are designed to keep water from being forced through your basement walls and floor. Most can be applied with a nylon brush and typically cure within 12 hours.
