How to Fix Foundation Cracks and Leaks from Outside in Lethbridge

Cracks and water leaks in your foundation can weaken your home and cause costly damage over time. While many homeowners notice problems from the inside, it’s also possible and often more effective to fix these issues from the outside.

This method helps prevent water from entering in the first place, keeping the structure dry and strong. Addressing cracks from the outside adds an extra barrier between your home and the soil, reducing the long-term risk of moisture damage. It also makes repairs more durable by stopping water before it reaches interior surfaces.

Here are 10 effective ways to fix foundation cracks and leaks from the outside:

1. Exterior Waterproofing Membrane

Applying a waterproof membrane directly to the outside wall helps block water from entering foundation cracks. This is one of the most reliable ways to protect basements and crawl spaces from moisture.

2. Excavation and Wall Sealing

Professionals dig around the home’s foundation to expose cracks and apply waterproof sealants or coatings. This method addresses leaks at the source and offers long-term protection.

Technicians can also inspect for hidden damage, clean the surfaces thoroughly, and ensure the sealants bond properly by fully accessing the foundation walls. It’s a thorough solution that strengthens the barrier between your home and outside elements.

3. Foundation Crack Injection (From Outside)

In some cases, cracks can be injected from the outside using polyurethane or epoxy materials that expand and seal the gap permanently.

• Suitable for narrow or deep foundation cracks
• Helps prevent water from entering through hidden pathways
• Can be done with minimal disturbance to landscaping

4. Installing a Drainage System

Installing a French drain or other external drainage system helps move water away from the foundation. This reduces pressure on the walls and prevents leaks.

5. Exterior Weeping Tile System

This system involves a perforated pipe installed at the base of the foundation to direct groundwater away. It’s especially effective in areas with high water tables.

6. Grading the Soil Away from the Foundation

Improper grading can lead to water pooling near your foundation. When the ground slopes toward your home, rainwater and melting snow can collect along the base, increasing the chance of cracks and leaks.

Resloping the soil ensures water flows away rather than toward the house, which helps maintain a dry and stable foundation year-round.

7. Waterproof Coatings or Paints

Some waterproof products can be applied directly to concrete walls to seal small cracks and prevent moisture from entering. This is a good option for minor surface issues.

8. Replacing or Repairing Exterior Footing Drains

Older homes may have damaged or clogged footing drains. Replacing them ensures proper water drainage and keeps the foundation dry.

• Helps prevent water buildup around the foundation base
• Supports the long-term stability of foundation walls
• Reduces the risk of basement flooding during heavy rain
• Improves overall drainage performance around the home

9. Installing Exterior Sump Pump Systems

If groundwater pressure is high, an external sump pump can help remove water that collects outside the foundation.

10. Sealing Gaps Around Utility Lines

Water can leak through spaces around pipes, cables, or utility lines entering the foundation. Sealing these areas with waterproof materials helps close off another source of leaks.
