Repairing and sealing wall cracks helps prevent future water intrusion.

Repairs for leaking wall cracks and pipe penetrations in basements

Small cracks in foundation walls are common in homes throughout the Maine area. Often a result of the natural curing process of concrete, these cracks typically don’t threaten the structural integrity of your foundation.

However, even small cracks can become a major issue if they allow groundwater to enter your basement or crawl space. We provide free estimates for basement wall crack repair services in Portland, Bangor, Rochester, and surrounding areas in Maine. Request a free estimate today!

Our Basement Wall Crack Repair Process

At TC Hafford Basement Systems, we use a proven, multi-step repair process to seal leaking wall cracks and help protect your home in the long term. Here’s what you can expect:

Drainage System or Drywell Installation: If your basement has an interior drainage system, the repair can be integrated to safely direct any future moisture to your sump pump. If not, a small dry well (typically 5–10 gallons) may be installed at the base of the crack to manage any potential water intrusion.
Sealant Application: We begin by applying a high-viscosity polyurethane sealant deep into the crack. This creates a durable, flexible barrier that helps prevent water from entering your home.
Secondary Drainage Layer: For added protection, we install a secondary drainage layer along the wall. This acts as a backup system, directing any water that may bypass the initial seal into your drainage system or dry well.
Create a Clean, Finished Appearance: To maintain a neat and professional look, the repaired crack is covered with a clean, finished surface that blends with your foundation wall.
Basement Floor Restoration: Once the repair is complete, the concrete floor is restored to a flush finish, leaving no gaps or openings. We take pride in leaving your space clean, tidy, and fully restored.

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!

Why Choose a Flexible Crack Repair Solution?

Many traditional repair methods, such as hydraulic cement, epoxy, or basic injections, can become brittle over time. As your foundation naturally expands and contracts with temperature and moisture changes, rigid materials may crack or lose adhesion, allowing leaks to return.

Flexible sealants, on the other hand, are designed to move with your foundation. This helps maintain a long-lasting seal and provides more reliable protection against future water intrusion.
