CONCRETE CARE

Cracks

WHY DID MY CONCRETE CRACK?

Cracks in concrete are not indicative of inferior materials or workmanship. Cracking in concrete is the result of shrinkage that occurs as concrete hardens and cures. Cracks can be minimized and controlled, but not eliminated.

Cracks in concrete floors, driveways, sidewalks, etc. can be treated cosmetically by our skilled technicians, but often times cosmetic treatment of cracks in flatwork bring more attention to the crack than if it were left undisturbed.

Cracks in poured concrete foundations are not uncommon and are usually 1/4 inch or less in width and can run the full vertical length of a wall. These types of foundation cracks are not considered problems, until they leak.

Foundation Crack Injection Process

Foundation cracks are sealed utilizing an injection process that seals the crack from the inside- out and eliminates water penetration. The pressure injection process pushes a urethane or epoxy resin through the wall, completely filling the crack as the cavity is injected from the bottom up.

Ported and Sealed Crack

To prepare a crack for injection, injection ports are placed over the crack, and the crack is surface-sealed with a bonding agent. All work is completed from the inside of the foundation. No digging on the outside of the foundation is required.

"Welded" Foundation Wall Crack

As the resin cures (within hours), it bonds to the hardened concrete, effectively "welding" the crack shut. The crack is sealed water tight preventing any further water penetration.
