Improve Drainage Outdoors, Seal Basement Windows, And Apply Sealant To Walls

Posted on

If your residential property does not drain well after heavy downpours, you may have encountered a situation in which rain water has dripped into your home's basement if there is a narrow crack surrounding each window in the foundation's walls. The following steps will teach you how to improve drainage outdoors, seal the basement windows with caulk, and apply a coat of clear sealant over the interior cement walls to prevent water from entering your residence and potentially causing damage. 

Materials

  • topsoil
  • gravel pieces
  • shovel
  • detergent
  • warm water
  • utility bucket
  • sponge
  • cleaning cloths
  • caulk gun
  • tube of caulk
  • plastic putty knife
  • waterproof cloths
  • waterproof concrete sealant
  • paint roller
  • roller cover and handle

Assess The Property And Add Soil And Gravel

Go outside to assess the property that surrounds your home. If you notice that there are indentations in the ground or portions of the property that are sloping toward your home, add shovelfuls of topsoil to depressions. Add small gravel pieces to window wells that surround your residence's basement. Gravel will prevent rain water from puddling and will improve drainage. After applying gravel, use the back of a shovel to disperse the gravel pieces evenly across the bottom of each window well. 

Clean The Walls And Add Caulk And Sealant

Go into the basement and inspect the windows that are installed in each wall to determine where gaps are located. If the windows are not within your reach, set a step ladder on the basement floor to stand on while checking each window. Use a soapy sponge to clean the portion of the wall that surrounds each window. Use a cleaning cloth to dry each wall. If you notice stains on other portions of the interior walls, wipe them off with the sponge. 

Attach a tube of caulk to the central part of a caulk gun. Apply the caulk around each window that is not sealed sufficiently. Use a plastic scraper to flatten and smooth out the caulk. Caulk will harden after a few hours. 

Use waterproof concrete sealant to seal the interior walls. Before applying the product, move loose items that are next to each wall and place the materials in the central part of the room. Drape waterproof cloths over the floor. After applying a cushioned cover over a paint roller and attaching a handle to the tool, dip the roller into a container of sealant. Spread the sealant across the walls in an even manner by pushing the roller in straight lines. Do not remove the cloths from the floor until the sealant has dried.
