If cracks appear in your foundation for any reason, it is important to repair it as soon as possible. Even if there are no serious problems, like water leakage, failing to seal the crack now will make it harder to repair it after a leak has started. The worst case scenario is basement flood repair. This means cleaning up a basement after it has flooded due to a foundational crack.
The most common way to repair a foundational crack is by using some form of injection. Think of caulking a bathroom, sealing the tiles is the only way to prevent water from ruining your bathroom arrangement. Similarly, you can repair a crack by injecting a sealant, usually urethane foam or hydraulic cement, into the crack, thus preventing it from growing. The urethane foam completely fills in the crack in all dimensions, from top to bottom and front to back.
The water inside the crack exerts something called hydrostatic pressure, which can force out any other sealant. Urethane foam is powerful because it completely engulfs the crack, thus preventing the pressure from exerting any force and ruining the integrity of the seal. Repairing a crack in your foundation is the only way to prevent it from getting worse. Consult with a professional Foundation Repair Dallas company in order to avoid any inadvertent accidents.
