  • Damp spots on the walls or floor

What causes a leaking basement and why?

Water can seep into your basement through cracks in the walls or floor, but there are plenty of other places it can break through. Look for weak spots around your basement, such as mortar joints (spaces between bricks or concrete blocks) tie rods that reinforce masonry, the junctures where the walls meet the floor, the top of your home’s foundation, or window wells. To understand why this basement leakage occurs, think of the hole that was dug when your home was constructed, as a bowl. With rainfall “this bowl” fills with water searching for weak areas in your basement walls to enter. The most common cause of serious problems is rainwater leaking through the basement floor or below ground level walls. In the mildest cases the water will slowly seep through porous walls and can be difficult to detect. In an extreme case, the water enters through visible holes and cracks and accumulates in deep puddles on the floor. Unfortunately, it is the water you cannot see that causes the most serious of leaking basement foundations.

What may be contributing to my mold and/or basement water problem?

Usually, wet basements occur in homes that lie in low-level water table areas or at the bottoms of slopes or hills, but the everyday shifting or settling of your home may also cause leakage. Other potential causes may be improperly designed drainage systems or poorly-mixed foundation concrete. New home additions or possibly swimming pools (whether in your yard or a neighbor’s) may also cause problems.

Why did our basement start leaking 5 years after we built our house?

What is the white chalky substance on our basement walls?

The substance is called Efflorescence. The chalky substance you are seeing is a result of a chemical breakdown of the bonding agent that holds your walls together. The water that is inside of your foundation wall will, over time, pull the lime cement out of the wall, leaving nothing to hold it together.

I have brown stains on my walls, what is this?

The brown stains are an indicator of Acid damage. The clay outside your home is very acidic, and when the water leaks into your basement it draws that acidity with it.
