Eliminate Water From Your Home's Basement, And Repair And Protect Concrete Walls

Water that accumulates on your residence's basement floor each time that it rains can cause extensive water-damage to your home's structure. Eliminate water from the basement and repair any damage in the basement's concrete walls by completing the steps below. Afterwards, apply a waterproofing sealant over the concrete to provide it with additional protection from damage, which could result in leaks.


  • sump pump
  • portable heaters
  • soapy water
  • scrub brush
  • putty knife
  • wire brush
  • vacuum cleaner (with hose attachment)
  • towel
  • tube of concrete filler
  • trowel
  • can of waterproofing sealant
  • paint roller and frame
  • paint tray and liner

Eliminate Water From The Floor And Dry The Surface

Rent a sump pump from a rental company or home improvement center to siphon water from the basement floor and deposit it outdoors. Most sump pump models need to be placed on a level surface before being plugged into an electrical socket. The siphoning hose needs to be placed in the puddled water and the transfer hose needs to be inserted through a window so that water will be dispersed outdoors. Once the water has been eliminated, set up a couple portable heaters in the basement to assist with drying the floor. 

Repair Damaged Walls And Apply Sealant

If you spot small cracks and grooves in portions of interior concrete walls, clean the affected areas with soapy water and a scrub brush. Use a putty knife or wire brush to help loosen small fragments of concrete that are stuck inside of the damaged sections. Use a vacuum hose to remove any concrete dust that remains on the walls. Dry the treated areas with a towel if they are damp.

Apply a thin line of concrete filler to each part of the wall that is physically marred. Smooth out the surface of the filler with a hand trowel. The filler needs to harden before applying a coat of sealant over it. The drying time may require several hours. Once the sealer has a firm, dry surface, mix the sealant and pour some of the product into a paint tray that has a liner inserted in it.

Add a coat of sealer to each interior wall. Roll the sealer across the concrete in straight lines. Once the sealer has dried, an additional coat can be added if you didn't effectively cover each wall with the first coat. In the future, water will not be likely to enter your home's basement and the concrete walls will not be susceptible to damage.
