Foundation Repair & Crack Repair in London, Ontario
Foundation repair and crack repair matched to the crack type, foundation and water source. From interior crack injection to exterior repair and wall reinforcement, we recommend the method that fits the problem.
Complete Foundation & Crack Repair Methods
From minor shrinkage cracks to structural wall issues, our foundation repair covers the full range of basement problems with methods matched to each situation.
Crack Injection
Seals leaking cracks in poured concrete from inside or outside. Material penetrates the full wall thickness to stop water intrusion.
Exterior Crack Repair
Where interior access isn't possible, the crack is exposed from outside, repaired, and sealed as part of the foundation wall.
Foundation Wall Repair
Repairs deterioration, impact, or movement damage matched to the type and extent of the wall condition.
Wall Reinforcement
Carbon fiber or steel reinforcement stabilizes bowing or moving walls based on foundation type and movement.
Parging & Surface Repair
Resurfaces spalled or parged concrete and seals the wall against further surface deterioration.
Cove Joint & Floor Cracks
Repairs seepage at the wall-floor joint and floor cracks with injection or drainage matched to the source.
Foundation Cracks We Repair
Every crack is different. We assess the type, location, and water source before recommending the right repair.
Foundation cracks aren't all created equal, and treating them the same way can waste money or leave a leak unresolved. Before we recommend a repair, we look closely at how a crack formed, whether it's still moving, and where the water is actually coming from. Shrinkage cracks that appear as concrete cures behave very differently from cracks caused by hydrostatic pressure, frost heave, or soil settlement around the foundation. Our technicians document crack width, direction, and pattern, then check for related signs like efflorescence, spalling, or gaps at the wall-floor joint that often point to a bigger drainage issue. That assessment tells us whether interior injection, exterior excavation and sealing, or reinforcement is the right long-term fix - so you're not paying for guesswork.
Foundation Repair Methods
Hover over each method to see how we match the repair to the crack type, foundation material, and water source.
Repair Method
Crack Injection
Seals leaking cracks in poured concrete from inside or outside the basement. Injection material penetrates the full wall thickness to stop water intrusion.
Seals leaking cracks in poured concrete from inside or outside the basement. Injection material penetrates the full wall thickness to stop water intrusion.
- Polyurethane or epoxy matched to the crack type
- Bonds the crack across the full wall thickness
- Stops active water seepage permanently
Where interior access isn't possible or exterior repair is more appropriate, the crack is exposed from outside, repaired, and sealed as part of the foundation wall.
- Excavation exposes the crack at the source
- Sealed and waterproofed from the exterior
- Ideal for cracks with heavy exterior water load
Beyond cracks, walls can suffer damage from deterioration, impact, or movement. We assess the condition and recommend repairs matched to the type and extent of the damage.
- Repairs spalling, parging, and surface damage
- Addresses deterioration and impact damage
- Matched to the foundation material and condition
Where walls are bowing or showing movement, reinforcement may be recommended to stabilize the wall based on foundation type and the nature of movement.
- Carbon fiber straps stabilize bowed walls
- Prevents further inward movement
- Low-profile, finished-wall friendly installation
Where the wall surface is spalling, parged, or deteriorating, we resurface and seal the area to protect the concrete and restore a clean finish.
- Resurfaces spalled and parged concrete
- Seals the wall against further surface damage
- Matched to the existing wall finish
Seepage at the wall-floor joint or floor cracks is repaired at the source, with injection or drainage matched to where the water is actually entering.
- Targets the wall-floor joint directly
- Injection or drainage based on the source
- Stops water tracking across the floor
