Concrete expands and contracts vigorously with the changing weather conditions. This back-and-forth expansion and contraction cycle takes its toll on concrete. Contractors cut gaps between sidewalk sections to provide "give" to the concrete slabs. Unfortunately, home foundations must be poured solid to prevent moisture leakage, so they may form cracks. You can follow an effective and simple method to fill these cracks to prevent any further damage. Does this Spark an idea?
Instructions
1. Measure the foundation crack from top to bottom to determine total length, and measure the width of the crack. Take into account the thickness (in inches) of your foundation wall as the entire crack must be filled. Write these down before purchasing your sealant so you know exactly how many injectors you will need to purchase. The packaging contains quantity information.
2. Purchase a high-quality epoxy or polyurethane and injector kit. Many manufacturers make them, and they may be found at your local lumber yards and department stores. RadonSeal produces filler materials which are also rated for blocking radon gas, offering a double-duty sealant.
3. Fill the foundation crack from bottom to top, not top to bottom. Beginning at the bottom will produce a base upon which the weight of the epoxy on top may rest without leaving gaps in the top, although some settling will occur.
4. Use a concrete trowel to level out the sealant bead on the foundation so it is even with the exterior of the foundation. Wipe the trowel clean with a damp cloth.
5. Allow the first injection of the sealant to rest for one hour. Return and fill in any areas at the top of the crack which may have opened up during settling of the sealant. Level the sealant once more and leave to dry completely.
