The way a basement wall is repaired is determined by the problem that caused the damage. Damage that occurs to the wall is typically caused by seepage or leakage. Wetness that occurs because of seepage or leakage happens for a number of reasons, each requiring a specific way to repair the damage.Continue Reading
One cause of wall wetness is roof runoff. To fix this issue, repair the home's gutters, eaves trough system and downspouts, and ensure that they are maintained regularly. The eaves trough must also slope away from the house and discharge at least 3 feet away from the foundation. For issues that occur with the home's foundation, use a filler to fill in holes in any openings between the soil and the basement wall. Installing a sump pump also helps to drain any excess ground water. Fix cracks in walls that are constructed of concrete blocks or cracks that are more that 1/2 inch wide by filling them in with a mixture of epoxy and sand. For walls that are constructed of poured concrete, clean any cracks in the wall and repair them using mortar, hydraulic cement or polyurethane.
Seepage means that groundwater is slowly coming through the pores of the wall, often appearing on the wall as damp spots. Leakage means that pressurized groundwater is quickly coming through wall joints and cracks in the wall. Seepage and leakage occur because the walls of the foundation or the surrounding soil is wet in addition to having weak spots in the foundation.Learn more about Carpentry
