What to Do About Basement Wall Cracks

How to Fix Basement Wall Cracks and Stop Leaks

Basement wall cracks can lead to water leaks, which often cause mold, bacteria, and pest issues. If your basement is leaking, here’s a step-by-step guide to identifying the source, evaluating the severity, and understanding the best options for waterproofing.

Identify the Source of the Leak

The first step in addressing a basement leak is to determine its source:

• Window Wells: If water is coming from a window well, consider installing a drainage system. A simple tray can catch water in the well, redirecting it away from your home.
• Wall Cracks: If cracks in your basement walls are the culprit, a more comprehensive solution is required.

Don’t Fill Cracks from the Inside

Avoid filling wall cracks from the inside. Water enters from the outside, so internal repairs only trap moisture inside the wall. Over time, this moisture will expand and contract with temperature changes, potentially causing severe damage. Proper waterproofing involves sealing cracks from the outside to create a lasting solution.

Assess the Severity of the Leak

Evaluate the extent of the water problem:

• Minor Moisture: If only slight moisture is appearing on interior walls, basement damp proofing may be sufficient.
• Pooling Water: If water pools on the floor or runs down the walls, basement waterproofing is recommended for more effective protection.

Choose Between Basement Damp Proofing and Waterproofing

Both damp proofing and waterproofing involve external repairs and trenching, but they offer different levels of protection.

Basement Damp Proofing

• Purpose: Designed to prevent general ground moisture from entering through wall cracks.
• Process: We repair cracks externally, then coat the outside walls to prevent moisture infiltration.
• Benefit: Damp proofing reinforces wall integrity and offers basic moisture resistance.

Basement Waterproofing

• Purpose: Ideal for homes exposed to high levels of groundwater, which can erode basement walls.
• Process: In addition to crack repairs and coating, we add a solid membrane as a barrier against groundwater. A drainage track is also installed to collect and redirect any water reaching the membrane.
• Benefit: Waterproofing offers maximum protection by actively redirecting water away from your home’s foundation.
