CRACK INJECTIONS
FOUNDATION CRACK REPAIR BY INJECTION IN MONTREAL, LAVAL AND SURROUNDING AREAS
A foundation crack in Montreal, Laval or the surrounding areas can have several causes, such as concrete quality, freeze-thaw cycles, water pressure, nearby trees or a lack of proper drainage. Worn French drains can also contribute to infiltration when water accumulates near the foundation.
Akton Injection offers injection services for foundation crack repair in Montreal, Laval, the West Island and the South Shore. Whether the crack is visible in the basement or on an exterior wall, our team can assess the situation and recommend a suitable intervention method. Call us to discuss your situation and get a personalized assessment.
SIGNS OF A PROBLEMATIC CRACK
A foundation crack in Montreal may seem minor at first glance, but how it changes over time deserves attention. A crack that widens, lets water through or returns after a previous repair may indicate a deeper issue in the foundation.
Watch especially for the following signs:
-
A crack that grows over time
-
Water infiltration near a wall or slab
-
Traces of moisture, mould or efflorescence
-
A crack accompanied by concrete movement
-
A persistent damp smell in the basement
An assessment can determine whether the crack is linked to infiltration, concrete movement or a structural issue. Talk to us about the signs you have noticed to plan an inspection based on your situation.
CAUSES OF CRACKS
Cracks can appear as a result of soil movement, water infiltration, poorly completed backfilling or repeated temperature changes. Before choosing a repair method, Akton Injection considers the location of the crack, its width, its progression and the visible signs around the affected area.
Depending on the diagnosis, different methods may be considered, including:
-
interior crack injection
-
exterior crack injection
-
epoxy injection
-
polyurethane injection
This assessment helps choose an intervention that is consistent with the type of crack and the conditions around the foundation. Contact our team to have the signs checked before the issue develops further.
HOW DOES FOUNDATION CRACK REPAIR WORK?
Every foundation crack in Montreal must be assessed according to its location, width, progression and the signs of moisture visible around the affected area. This analysis helps choose a repair method that reflects the actual condition of the building.
Our approach generally follows several steps:
-
Crack inspection: we observe the crack, nearby surfaces and signs of infiltration or concrete movement.
-
Diagnosis: we determine whether the issue is mainly linked to water infiltration, a non-structural crack or a concern that requires a more targeted intervention.
-
Repair: we use the method suited to the type of crack, such as interior injection, exterior injection, epoxy or polyurethane.
-
Verification and finishing: we check the result, clean the work area and complete the necessary finishing according to the intervention performed.
This process helps clarify the source of the problem and choose an intervention suited to the observed conditions.
INTERIOR CRACK INJECTION
In the field of basement waterproofing in Montreal and on the North and South Shores, Akton Injection has worked on cracks in concrete foundations for more than a quarter of a century. Before waterproofing your basement, it may be necessary to treat the crack at the source to limit infiltration and preserve the condition of the foundation.
Get in touch with us to determine whether an interior crack injection is right for your situation. This method may be part of a foundation repair when interior access makes it possible to treat the crack effectively.
EXTERIOR CRACK INJECTION
When exterior access allows it, an exterior crack injection may be recommended to treat the crack from outside the building. This method requires more workspace, but it allows the intervention to be performed directly on the area exposed to water pressure.
Combined with an appropriate drainage slope, exterior injection can help reduce pressure against the foundation wall and better control infiltration near the crack.
EPOXY INJECTION
Epoxy injection in concrete can close certain cracks with an epoxy resin. When the crack involves a structural concern, this method can help restore continuity in the concrete and protect reinforcing bars against water.
The choice of epoxy depends on the type of crack, its opening and the repair objective. Crack analysis helps determine whether this method is more appropriate than polyurethane injection or another intervention.
POLYURETHANE INJECTION
Polyurethanes are used to seal and waterproof certain cracks that may experience slight movement due to seasonal temperature changes. This method is often considered when a leak is present behind the crack.
Polyurethane foam expands after injection, which helps it fill the targeted space and limit flow out of the crack. It adds almost no structural strength, but it can be suited to many residential situations where the main concern is water infiltration.

FREQUENTLY ASKED QUESTIONS
Do you have questions about foundation crack repair by injection? These answers cover signs to watch for, injection methods and situations where an assessment may be useful.
1. Is a Crack in the Foundation Always Dangerous for My Home?
Not necessarily, but it should be assessed by a professional. Some cracks are aesthetic, while others can affect the structure and cause water infiltration.
2. What Is the Difference Between Epoxy Injection and Polyurethane Injection?
Epoxy restores the structural strength of concrete, while polyurethane seals non-structural cracks and blocks water.
3. Can a Crack Be Repaired from the Outside Without Excavating Everything?
Yes, depending on the configuration of the property. Exterior injection is often preferred when access is possible for better protection.
4. How Often Should I Inspect My Home’s Foundation?
Do a visual inspection once a year, especially after winter. This helps identify signs of cracking quickly.
5. When Should Interior or Exterior Injection Be Chosen?
The choice depends on access to the crack, the location of the infiltration and the conditions around the foundation. An inspection helps determine the most appropriate method.
