Foundation Crack Repair in Edmonton
Sherwood Park & Edmonton Foundation Crack Repair Experts
Crack injection works by injecting expanding polyurethane foam into the crack along its entire width and length. This is a permanent fix that does not need to be repeated. The injected polymers, unlike other surface repairs, are not subjected to weathering, traffic, or ultraviolet rays.
Most importantly, the crack injection will prevent costly future repairs and problems. The potential damage caused by water leaks in the finished basement, as well as the cost of repairing concrete walls due to corrosion, demonstrate the clear benefits of permanent crack repair. The best way to repair poured concrete walls is with an injection.

POLYURETHANE INJECTION
Polyurethane is a concrete repair material that expands when it comes into contact with a special liquid to fill the crack. As the foundation shifts, the polyurethane remains flexible, effectively stopping the leak. Foundation Concrete Crack Repair is performed from the inside, eliminating the need for digging from the outside. Holes are drilled through the soil along the crack, and polyurethane is injected.
EPOXY INJECTION
Only for structural purposes, and even then only if the concrete is dry, is epoxy injection recommended.
HOW FOUNDATION CRACKS DEVELOP
Almost all residential foundations have cracks. They frequently appear in window corners, pour lines, holes for service lines, or rod ties. Among the various causes are:
HIGH WATER CONTENT RESULTING IN POOR CONCRETE MIX
RAPID CURING OF CONCRETE
CONCRETE FORMS REMOVED PREMATURELY (I.E. 2 DAYS VS 7)
FILL SOIL BEING IMPROPERLY COMPACTED
UNEVEN MOISTURE AROUND THE FOUNDATION
POOR DRAINAGE
HYDRO-STATIC WATER PRESSURE
Because soil properties vary, not every point on a foundation will settle uniformly, resulting in cracking walls and racking door frames. A well-built structure will reduce overall settlement and prevent differential settlement.
Even small cracks will grow larger over time and can cause BIG problems, such as structural integrity loss. To avoid extensive damage, all cracks that may be or are exposed to moisture must be repaired as soon as possible.
TYPES OF BASEMENT CRACKS
HAIRLINE CRACKS - The majority of foundation cracks appear within the first year of construction. Common wall cracks do not cause structural problems or foundation failure. The most serious issue with these is water leakage.
VERTICAL CRACKS - The shrinking of the concrete as it cures causes typical foundation cracks to run vertically or at an angle, as does settlement.
HORIZONTAL CRACKS - If the crack is located in the middle of the wall, it is subject to lateral pressure, causing the wall to bow and causing structural damage.
More than 1/4" wide cracks, horizontal cracks, cracks with misaligned edges, or continued movement may necessitate an engineering evaluation. Mark the ends of the crack and make alignment marks at various points on the wall to monitor the crack length and movement.
