Small cracks in your home's concrete foundation can cause water to leak into the basement and can become worse over time. Learn how to patch these areas with the following steps. Once you have finished the repair steps, damage will not occur to the foundation when it rains and the basement will stay dry.

Materials

  • face mask
  • wire brush
  • broom
  • shop vacuum cleaner
  • mild detergent
  • sponge
  • tube of concrete patch
  • caulking gun
  • putty knife
  • vinyl tarps
  • waterproofing sealer
  • paint roller
  • roller handle and frame

Remove Loose Pieces Of Concrete And Clean The Walls

Put on a face mask to prevent breathing in dust. Remove loose pieces of concrete from the basement's interior walls with a wire brush. Move the brush briskly back and forth over each cracked area to remove the damaged pieces of concrete. Use a broom or shop vacuum cleaner to collect the loose pieces. Clean the basement walls with a soapy sponge. Rinse the sponge out and wipe the same parts of the wall. Wait for the concrete walls to dry completely.

Fill Cracks And Add Sealer

Insert a tube of concrete patch in a caulking gun. Squeeze the gun's trigger as you move the tip of it across each crack. Once the cracks are filled, smooth out the patch with a putty knife so that it is uniform with the interior walls. Wait a couple hours for the patch to dry.

Place vinyl tarps on the floor in front of each wall. Apply waterproofing sealer over the interior walls. Begin in the bottom corner of one of the walls. Move a paint roller that is covered with sealer in straight lines, rolling it upwards. Apply more sealer to the roller as needed. After all of the walls are covered with sealer, wait for them to dry. If some of the concrete walls are not covered completely, add a second coat of sealer. After the sealer dries, remove the tarps from the floor. The walls will stay dry whenever it rains in the future.

Maintain The Concrete Walls

Keep the interior walls in the basement maintained by occasionally cleaning them off with a sponge and mild detergent. Rinse away the soapy residue with water and pat the walls dry with a towel. Avoid using commercial cleaning agents or abrasive cleaning tools that can damage the walls. The waterproofing sealer will last for several years and keep your basement protected from damage.
