Wall Cracks in Your Basement

Small cracks can lead to large issues if they allow water to seep into your basement. Learn more about wall cracks and the solutions to protect your home.


Warrantied repairs for leaking wall cracks & pipe penetrations

Small cracks in foundation walls are common in homes throughout the North Carolina area. Usually a side effect of the natural curing process of concrete, these cracks usually do not threaten the foundation.

However, even small cracks in a foundation can be a major problem if they leak groundwater into your basement or crawl space. If you’d like a free foundation crack repair quote, contact us today!

Steps to Repairing Crack in Foundation Wall

At Dry Pro Foundation and Crawlspace Specialists, we recommend a Foundation Crack Repair Sealant to repair your leaking wall cracks. It’s a patented, warrantied repair and a permanent solution. To repair a flooding or leaky wall crack, we follow these five steps:

  • Installation of a Drainage System: If you’re waterproofing your basement with BasementGutter™ or another interior drainage system, the foundation crack sealant can be integrated with it to direct any potential leaks to your sump pump. Otherwise, a small dry well about 5-10 gallons in size is created at the base of the crack.
  • The Polyurethane Sealant: We start by sealing the crack with a high-viscosity polyurethane polymer. This gets deep into the cracks to form a durable, flexible seal.
  • Secondary Drainage Strategy: Your polyurethane polymer seal should never fail. If it ever does, 95% of the water should still be stopped from leaking in. To ensure a proper repair, we install a secondary layer of drainage on the basement wall — one that will direct water to your basement drainage system or dry well.
  • Finish the Repair: To keep your foundation walls looking great, we overlay your sealed wall crack with a polyurethane sealant. Light gray in color, it gives the repair a professional, finished appearance.
  • Restore the Floor: After the wall crack has been repaired, the concrete floor is restored flush, with no gaps or openings. We pride ourselves on leaving our workplace clean and neat. The end result of the foundation crack repair installation is a professional-looking, top-performing basement wall crack repair that includes a written warranty.

Why our Foundation Crack Repair System over Injection?

Unlike hydraulic cement and some epoxies, the special sealant we use will never dry out or re-crack over time.

Additionally, hydraulic cement, epoxies, and even urethane injections are not able to bend and stretch along with your foundation movement. As concrete walls expand and shrink slightly through freeze/thaw and wet/dry cycles, the bonds of these materials will fail and the crack will leak again.

Our system stays bonded with wall movement, and seals the crack permanently, no matter what!

Basement Finishing Tip: While leaking wall cracks must be fixed before you finish your basement, your finished basement walls will also need to be protected from water vapor that continually passes through concrete. Stop this moisture by installing an appropriate wall vapor barrier on basement walls before finishing.
