If one of the concrete walls in the crawl space that is connected to your home's basement is chipped and water seeps through it whenever it rains, repair the damage with the following steps. Afterwards, waterproof the storage space by adding a coat of sealant to each wall's interior.
- drop light
- drop cloth
- soapy water solution
- spray bottle
- bucket of water
- oscillating fan
- concrete patch
- putty knife
- hand sander
- fine grit sandpaper
- concrete sealant
- paint tray
- paint roller
- roller handle and frame
Remove Loose Pieces Of Concrete And Clean Each Interior Wall
Use a step ladder to climb into the crawl space if its entryway is elevated. Plug in a drop light if there isn't standard lighting in the room. Line the flooring in the crawl space with a drop cloth. Place the tip of a chisel directly over loose pieces of concrete. Gently tap the back of the tool with a hammer to break off each damaged piece.
Once finished, clean the interior walls in the crawl space with a soapy solution that has been added to a spray bottle. Wipe dirty surfaces with a damp sponge. Rinse the interior walls with plain water when you have finished. Set up an oscillating fan inside of the crawl space to assist with drying the walls.
Apply Patch And Sand The Repaired area
Use a trowel to apply an even amount of concrete patch to the damaged wall. Smooth out the edges of the patch with the flat side of a putty knife. Wait for the product to harden. Once this occurs, lightly sand the repaired area with a hand sander. Wipe the wall with a damp sponge to remove residue that remains as a result of sanding the concrete surface.
Apply Sealant To Each Interior Wall
Pour some concrete sealant into a paint tray. Apply the sealant to each interior wall. Begin in one corner of wall and move a paint roller that is covered with sealant across the concrete surface in straight lines. Once all of the walls have been covered, wait for the sealant to dry. Afterwards, remove the drop cloth and any materials that were use to make repairs from the crawl space.
Water will no longer penetrate the part of the wall that was previously damaged. The remaining walls will have a protective layer added to them, which will prevent moisture-related damages as well. For a tough job, contact a crawl space waterproofing professional.Share
