Clean all guttering around the house. Clogged gutters do not allow water to drain effectively. Instead, water will spill out over the top of the gutters soaking the ground near the basement walls. Install guttering around the house where none exists. Lack of guttering will lead to ground erosion around the foundation.
Extend downspouts away from the house. Install a 5-foot extension onto the end of each downspout by sliding it on to the end of the downspout and screwing it on. Alternately, use flat plastic extenders that slide on or troughs that sit on the ground underneath the downspout to direct water away from the foundation.
Raise the soil level around the foundation so that is higher than the rest of the yard. Use the garden rake to pull the soil from the foundation at a downward sloping angle into the yard.
Apply an epoxy concrete sealer to the inside of the basement walls. Epoxy sealers will fill small cracks and stop water from seeping in through the pores in the concrete. Use a paintbrush to cut in the sealer at the floor and ceiling level, and roll the sealer onto the walls. Allow the sealer to dry, and apply a second coat.
