FIX-SURE CRACKS PRIVILEGE A HIGHLY PERFORMANCE CRACK REPAIR TECHNIQUE
Les injections de polyuréthane flexible sous haute pression se font à l’intérieur du bâtiment, elles ne nécessitent pas d’excavation et sont réalisables 365 jours par année!
Our team makes sure to repair everything perfectly, in order to avoid future problems.
TO ENSURE THE WORK IS CARRIED OUT PROPERLY, OUR TECHNICIAN DRILLS HOLES ALL ALONG THE FOUNDATION CRACK.
Subsequently, the crack and the holes are thoroughly cleaned of any dust, and the surface crack is sealed with an epoxy plaster (in order to keep the polyurethane inside the crack).
Des ports d’injection mécanique en métal sont installés dans chaque trou. Ensuite, nous injectons de l’eau, puis du polyuréthane flexible sous haute pression. Le polyuréthane en entrant en contact avec l’eau injectée réagit instantanément et gonfle jusqu’à remplir complètement et instantanément la cavité.
THE REPAIR IS DONE IN 5 STEPS:
- The technician drills holes all along the foundation crack.
- The crack and holes are cleaned well to remove dust.
- An epoxy plaster is used to seal the surface crack, thus containing the polyurethane.
- Metal injection ports are installed in each previously drilled hole.
- Water and flexible polyurethane are injected under high pressure inside the crack.
The polyurethane, upon coming into contact with water, reacts instantly and swells until it completely fills the cavity.
SOME IMPORTANT POINTS TO CHECK TO PREVENT CONCRETE CRACKS:
- Presence of a functional drainage system all around the foundation
- Effectiveness of gutters to collect water flowing from the roof and redirect it to recovery points
- Slopes of the land correctly directing water away from the foundation
- No damage to the foundation
