How Do You Repair Cracks & Deteriorating Concrete Foundation?
Concrete is a strong, durable building material that can last for decades with only minimal maintenance. Eventually, though, even the best-laid concrete foundations may develop faults. Cracks in the stone or deterioration are common ailments but can be repaired, slowing the damage and adding years to your foundation. Cut out the damaged portion of concrete. Cut the area at 90 degree angles, forming a square centered on the damaged area that’s 3/4 inches wider than the area. Do not cut into the reinforcing steel. Clean steel reinforcement bars completely, removing any rust. If the steel also is damaged, replace it with new bars. Fill the cut areas with a shrink-resistant repair mortar and level it with a steel trowel. Route cracks out from the surface using a crack chaser blade. Use the blade to open the crack to a depth of 3/4 to 1 inch, and create a vertical face on the crack sides. Flush out the crack with water to remove dirt or debris and allow it to dry completely.
