Laid-up masonry basement walls on concrete footers are sturdy, economical, and comparatively simple to erect. Combine those attributes with the fact that they allow great design flexibility, and you’ve got a pretty fair explanation of why concrete block basement walls are so common. Unfortunately, water leaks all too often seem to be another standard feature of block basement walls.

Solving Basement Water Problems

Once you’ve determined where the water in your basement is coming from, follow the key numbers to find solutions appropriate to your problems.

The simplest, least expensive way to solve surface water problems is to landscape the area around your house to prevent surface water from saturating the soil next to the basement walls. The ground should slope downward from the house at least 4 inches in the first 6 feet, and no shrubs or trees should be planted closer than 3 feet from the walls.
