Foundations are the base of any structure. When they show signs of weakness, it’s crucial to act quickly with effective repair methods. Thanks to technological advances, modern techniques now allow foundation problems to be corrected with more precision, durability, and often, less invasiveness.

In this article, the team at Marco Réparation de Fondation, foundation repair experts in Quebec, presents the most commonly used modern methods to get your foundation back in good shape.

1. Polyurethane or Epoxy Injection

Resin injection is a fast and highly effective solution for filling cracks in concrete foundations.

  • Polyurethane: used for active cracks or ones exposed to water. It stays flexible and moves with the concrete.
  • Epoxy: ideal for structural cracks. It hardens and restores the concrete’s strength.

👉 This method allows for an internal repair without having to dig outside.

2. Helical Pier Installation

Helical piers are an innovative solution for stabilizing foundations that are sinking or unstable.

  • Fast installation without major excavation
  • Suitable for all soil types
  • Immediate resistance after installation

This technique transfers the weight of the house onto more stable soil, preventing future settling.

3. Wall Anchors

When foundation walls start to bow inward (often due to soil pressure), wall anchors help stabilize and straighten the affected walls.

  • Minimal disturbance to the property
  • Reinforces the structure without demolition
  • Permanent result, with monitoring possible

4. Waterproofing Membrane and French Drain

To prevent water infiltration, experts often recommend a combination of waterproofing membranes and modern French drains.

  • Elastomeric or spray-applied membrane: effectively seals the foundation
  • French drain: carries water away from the foundation

This method is essential for protecting your basement against moisture and mold.

5. Slab Jacking (Polymer Injection Lifting)

This method involves injecting an expanding foam under a sunken slab to bring it back to level.

  • A fast alternative to slab replacement
  • Less costly than traditional methods
  • Ideal for sidewalks, patios, or garage floors
