How to Fix Water Problems in the Basement
- 1). Identify the source of the leakage. Consider whether it comes from surface water (rain or snow), ground water (nearby springs) or other water (improper plumbing, condensation outside).
- 2). Change the grading along the home's foundation so that it diverts water flow away from the house. Make sure the grading slopes no less than six inches, and preferably at least eight inches, away from your foundation.
- 3). Observe how effective your gutters are in draining water from the roof, particularly the excavation ring. Replace gutters that don't extend past the excavation ring of your roof, or gutters that leak or are damaged.
- 4). Inspect the foundation walls and floors for cracks. Use mortar or polyurethane caulk to fill small cracks, and rubber membrane or epoxy for large ones. If gaps exist between the walls and floors, fill them with foam backer rod or epoxy crack fillers.
- 5). Check the window wells, which should be sufficiently above the ground slope that water drains away from the foundation. Cover side window wells with plastic bubbles, so that rain and snow cannot seep through.
- 6). Install a drain tile system which pools water and diverts it to a sump pump. Dig up about 12 inches of concrete around the foundation's perimeter. Replace some of the dirt with fine stones covered with a plastic drainage tile, and then add more stones. Cover the drainage tile with a fresh batch of concrete.
- 7). Examine the pavement near the house. Dig up and replace any patios or walkways that slope toward the foundation. Or you may change the pavement's slope by pouring another layer of concrete over the existing pavement.
