Epoxy Crack Repair in Ottawa – Long-Lasting Foundation Solutions

A cracked foundation is a warning sign that your home’s structural stability may be at risk. While small cracks may seem harmless, they can quickly widen due to moisture infiltration, soil movement, and freeze-thaw cycles. If left untreated, foundation cracks can lead to water leaks, mold growth, and costly structural damage.

At Ottawa Masonry, we specialize in epoxy crack repair, a durable and effective solution for sealing foundation cracks and restoring structural strength. Whether you have hairline cracks, vertical fractures, or leaking foundation walls, our high-strength epoxy injection process ensures a permanent, waterproof seal to protect your home.

What is Epoxy Crack Repair?

Epoxy crack repair is a specialized technique used to seal foundation cracks with high-strength epoxy resin. Unlike standard sealants, epoxy bonds the concrete together, making the repaired section stronger than the surrounding concrete.

Why is Epoxy Used for Foundation Crack Repair?

  • Structural Reinforcement – Epoxy restores the original strength and stability of the concrete.
  • Waterproofing Protection – Seals cracks completely to prevent moisture infiltration.
  • Long-Lasting Durability – Withstands soil pressure and seasonal expansion/contraction.
  • Cost-Effective Alternative – Less invasive and more affordable than foundation replacement.

When is Epoxy Crack Repair Needed?

Epoxy crack repair is needed for structural cracks in concrete foundations, preventing water intrusion and restoring strength to the damaged area.

Hairline Cracks

Though small, these cracks can expand over time if left untreated. Epoxy injection prevents further deterioration.

Vertical Foundation Cracks

Common in settling foundations, vertical cracks should be sealed to prevent water infiltration and structural weakening.

Basement Wall Leaks

Water seeping through cracks in foundation walls can lead to mold growth and interior damage. Epoxy provides a waterproof seal to stop leaks.

Cracks in Load-Bearing Walls

Cracks in structural foundation walls indicate potential weakness in the foundation and should be repaired with epoxy for reinforcement.

Before Waterproofing Applications

For basements being waterproofed, sealing existing cracks with epoxy ensures a fully protected foundation.

What Causes Foundation Cracks That Require Epoxy Repair?

Soil Movement & Expansion

Expanding and contracting soil creates constant pressure on foundation walls, leading to cracks and shifts.

Freeze-Thaw Cycles

Ottawa’s harsh winters freeze water inside small cracks, forcing them to widen as ice expands. This cycle repeats every season.

Water Infiltration & Hydrostatic Pressure

Water accumulating around the foundation increases hydrostatic pressure, which forces moisture through foundation walls, widening cracks over time.

Poor Construction Materials

Weak concrete mixes, insufficient reinforcement, or shallow foundations make structures more susceptible to cracking.

Aging Foundation

Older homes develop cracks due to natural wear and tear, requiring professional reinforcement.

Stone Masonry

Offers fire-resistant and weather-proof properties.

Chimney Repair

Provides structural integrity to buildings.

Our Epoxy Crack Repair Process

At Ottawa Masonry, we follow a detailed and precise process to ensure cracks are sealed permanently.

Crack Inspection & Assessment

Our experts conduct a thorough inspection to determine the severity and best repair method.

Crack Preparation

  • The crack is cleaned and slightly widened to allow for better epoxy penetration.
  • Any loose debris is removed to ensure a strong bond.

Epoxy Injection Application

  • High-strength epoxy resin is injected into the crack.
  • The epoxy fills the entire crack depth, bonding the concrete back together.
  • Once cured, the epoxy restores the foundation’s original strength.

Curing & Final Inspection

  • The epoxy hardens to form a watertight, structural seal.
  • Our team inspects the repair to ensure long-term durability.
