3 Signs Water Is Seeping Through Your Basement's Concrete Walls

If you live in a home that has concrete walls in your basement, you may wonder if water is leaking into the area from surrounding soil, even though you have not seen any water pouring in. If so, look for the following signs that water is seeping through the concrete walls in your basement.

Strong, Musty Odor Detected Around the Area

You may have started noticing a strong, musty odor in your basement, with the smell being the strongest around one or more of the walls.

This pungent odor could be a combination of several things; you may be smelling dirt, wet concrete, and even fungal growth. If you detect this musty odor, continue below to inspect your walls for other indicators of water seepage.

White Crystalline Powder Is Present on the Walls

While you look at the surface of your basement walls, you may find a white crystalline powder on the surfaces. This powder, called efflorescence, is formed when water seeps through concrete structures.

As the water pushes its way through tiny cracks and pores in the concrete, it carries with it minerals from the material and the soil. When the tiny droplets of water land on the interior surfaces of your basement walls and evaporate, these minerals are deposited.

As the mineral deposits accumulate, they are then seen as a powder. If you see efflorescence on your walls, water is seeping through your walls, and there may be something more sinister forming on them, as discussed in the next section.

Mold Starts Growing on the Surface

When water seeps through the concrete, the material stays wet inside, even though the surface may seem dry. With the constant moisture and dark area, the concrete then becomes an ideal breeding ground for mold.

While you may not be able to see it at first because the spores are growing inside the walls, the fungi will eventually spread to the walls' surfaces. When they do, you will start seeing dark green slime or fuzzy areas on the walls.

Since mold can have serious adverse effects on your family's health, something should be done as soon as possible to control the moisture and stop the fungi's growth.

If you find one or more of the above signs of water seepage, you may have damage inside and around the outside of the walls you cannot see. Contact a basement waterproofing contractor service so they can send someone to inspect your basement and offer solutions for keeping the water out and preventing further damage.
