The advantages of a foundation crack repair by injection

No excavation necessary!

Repairing foundation cracks usually requires excavation along the foundation, which can cause significant damage to the building. Our 45-degree injection technology eliminates damage or destruction to your foundations for such strong and long-lasting results.

Fast and efficient process

Foundation crack repair is done using injections in the center of the concrete structure. Holes are made using a drill to inject exactly in the center of your foundation, which ensures an even and solid application of our product. With a significant portion of our income reinvested in research, our concrete structure injection service is the most efficient in Quebec!

Passive cracks

A crack can be considered a passive crack if they do not get worse over time. These cracks are often part of a home’s natural aging process and are therefore minor. To repair a passive crack, a simple filling should do the trick.

Active cracks

An active fissure may be more difficult to treat. If the crack deteriorates over time, it is important to call a professional. This expert can identify the source of the problem and take steps to resolve it. Often, active cracks are due to freezing, poor drainage, or ground subsidence.

If you detect the presence of cracks in your home, the best thing to do is to call a crack expert to determine if you have active or passive cracks. Whether shrinkage cracks or other types, the Foundation Fissure team can repair concrete cracks quickly and professionally!

Why avoid excavation during foundation repair?

The majority of contractors who offer a foundation crack repair service do it from the outside, and very often, the owners ask for exterior work so as not to have a construction site in their living space. However, there are several disadvantages to excavation around foundations.

Is the repair from the inside as effective?

Both repair methods are effective, but working from the inside can detect hidden water infiltration and effectively deal with mold. Small openings of 24 inches are usually sufficient for this technique, which is more economical than excavation for building owners!

In addition, since Fissure Fondation injects from the inside, foundation crack repairs can be done year-round: no need to wait for the ground to thaw!

1. Vous aurez besoin de beaucoup plus d’équipement pour réparer une fissure de fondation depuis l’extérieur! A power shovel will need to be brought to the site to dig a hole to access the base of the foundation wall, and the hole must meet CNESST safety standards for collapse.

2. You risk causing more damage to your foundation! Excavator vibrations can cause tiny, invisible cracks that can lead to water seepage later.

3. Crack repair work takes much longer because of the excavation, and it doesn’t have to rain for the repair to be successful! The contractor will have to clean the surface of the foundations, inject polyurethane, place a waterproofing membrane to prevent water infiltration, and many other things: it therefore takes more time!

4. Expect potential damage to landscaping, asphalt parking or interblock!

What causes foundation cracks?

1. The natural aging of the building

Land subsidence can be caused by urban development, low soil bearing capacity and drought. Clay soils can become particularly fragile during periods of drought, which can cause cracks in properties and damage to house foundations. Fortunately, it is rather rare in Quebec!

2. The effect of freezing and thawing on concrete

In winter, the expansion of water naturally present in the earth can put pressure on the walls of a house. This pressure can lead to the formation of cracks, which increase in size depending on the severity of the frost. It is therefore advisable to move water sources, such as gutters, away from the house if possible.

3. Soil subsidence under and around the building

The action of water can have significant consequences on the foundations of a building, particularly in regions where there is significant freezing and thawing. Water infiltration can permanently damage foundation walls if homeowners don’t do a quick crack repair.

4.Water infiltration in the foundations

As a property ages, it is common to see cracks appear due to structural movement and degradation of materials. Yes, even concrete has a limited lifespan: after several decades, it begins to weaken.
