How to Fill the Gap Involving the Basement Foundation

Protecting a basement foundation from water damage and mold and cracking is vital. A gap between a basement foundation as well as a sidewalk leaves both structures at risk of severe water damage and mold. Filling the space with semi-flexible, rot-resistant material blocks moisture while allowing the structures to shift without cracking. Do-it-yourself individuals with minimum experience can complete this project in the afternoon including a full day for that caulk to set.

Remove a real difference relating to the foundation and sidewalk having a long wire brush. Chip off any hard debris or caulk stuck on the sides using a hammer plus a chisel. Look at the width in the gap with measuring tape. If it’s wider than 1/2 inch, you’ll have to fill out the gap by having an expansion joint like foam backer rod. If it’s under a 1/2 inch wide, you can fill out Expanding Foam Tape. Place a strip of froth backer rod on top of the sidewalk parallel on the gap. Utilize a utility knife to cut the rod to suit the size of a real difference. When the rod isn't good enough, cut another piece to adjust to the remainder space. Lay the foam backer rod on top of the gap and push it down together with your hands. If you’re using two lengths of rod, push these down therefore the ends are flush. Utilize blunt end of a putty knife hitting the rod into the base of the visible difference. Load silicone latex caulk in a caulk gun and snip off of the end with scissors. Fill the rest of the gap using the caulk until its level together with the sidewalk. Hold a putty knife level with one for reds over the pavement and yet another in the caulk. Run the knife slowly along the length of the gap to remove excess and make sure that the caulk is level.
