Injection repair involves sealing the cracks in your foundation, using an injection technique from the outside as well as inside your home. Fast and affordable, this technique requires no excavation and no turnaround time. This allows a repair in all conditions, even if there is a water infiltration during the repair. In addition to being able to be done at any time, regardless of the season.
What are foundation cracks?
Foundation cracks are visible disruptions or gaps in the concrete or masonry structures that serve as the base for buildings. These can be minor or superficial, but some may indicate serious structural issues. Various factors, including soil pressure, poor construction methods, material shrinkage, or extreme temperature changes, may cause cracks. Depending on their nature, location, and size, they can lead to problems like water leakage, infestations, and in severe cases, structural instability. Therefore, prompt inspection and repair are usually necessary to maintain the safety and longevity of the building.
Naturally, concrete is a material that is prone to shrinkage and therefore prone to cracking. The presence of cracks on your foundation is not always a worrying case, but it is still more prudent to remedy it preventively.
Foundation Crack Injection
Before the repair, our team will make sure to assess the state of your cracks, whether they are passive or active. Passive cracks are due to the removal of the concrete or initial bad compaction, they stabilize after one year. While active cracks get worse over time. It is important to evaluate the cracks so that they are stabilized before repair.
Polyurethane is a resin designed to seal cracks to prevent leakage. Its flexibility that allows the natural movement of concrete. When the polyurethane is injected into the cracks, it expands to 7 times its volume, thus sealing the crack completely regardless of the thickness of the wall (from 8 to 30 centimeters).
Fixing a foundation crack early on is paramount due to the potential for escalating structural issues and increased repair costs over time. If left untreated, what might initially be a minor crack can progress, compromising the structural integrity of the building. This can lead to serious safety concerns, including partial or total collapse risk. Moreover, even more, minor cracks can serve as access points for water, leading to moisture problems, mould growth, and potential damage to interior spaces and property. Early intervention mitigates these risks and proves more cost-effective in the long run, as it prevents the need for more extensive—and expensive—repairs or renovations down the line.
At the request of the manufacturer and / or the engineer, the injection can also be done with epoxy
