Polyurethane Foam Injection
It is almost inevitable that overtime walls and foundations will develop cracks. These cracks are sometimes caused by wet conditions or simply leveling issues into the foundation. To fix these cracks, there are many methods, but the one we are going to talk about here is polyurethane foam injection. This type of repairing is cheap and it can guarantee a long-lasting effect. The injected foam goes through the crack in the soil behind the wall and makes sure to support the wall to not develop further cracks. This fixing method is done from inside of the wall only.
