Why does my basement leak?

(1) Hydrostatic Pressure - water penetration up from below your basement floor. This is the result of the ground water table rising upward.

(2) Lateral Pressure - water penetration through your foundation walls. This can result from water movement through natural underground veins, from poor ground drainage or downspouts that empty too close to your foundation, or from water simply building up in the hole in which your house sits.

Basement leaks are very common.

Why should I fix this problem?

Nobody likes having to worry about a wet basement, especially when it rains. Fixing your basement now can only help maintain or increase the value of your home. A home with a finished basement that can be used as extra space such as a playroom, exercise room or home office can increase the value of your home.

Why are there cracks in my basement walls?

Cracks in your basement walls are a sign of settling. Cracks can be an easy way for water entry into your basement. Cracks can compromise the structural integrity of your foundation. Large cracks, cracks that have visibly grown over time, or bowed or buckling walls need immediate attention. The average house places over 50 tons of weight on its foundation walls, so the integrity of the walls must be maintained.

Why are there cracks in my basement floor?

Cracks in your basement floor can also be caused by settling and shifting in your foundation walls, in the footer underlying your foundation, or in the floor (or "slab") itself. However, floor cracks are more frequently caused by hydrostatic pressure. The water pressure from below the floor must escape somewhere, so it pokes a hole or crack in your basement floor.
