Is your basement waterproof?
Wet basements, foundation leaks, and cracks are not restricted to only old buildings. Moisture content on the walls and surfaces in the basement, with water leaking into it, has become a common sight even in new buildings. Keep in mind that long-term water exposure in your basement can even erode the value of your home.
Why basements leak?
When the basement of your house is excavated, the soil that backfills the foundation would be loose compared to the surrounding ground, which remains undisturbed. This makes it easier for the water to quickly seep through the loose soil and accumulate. When the foundation walls are constructed and the ground is backfilled, this loose soil with a high amount of moisture is packed against the walls. As water accumulates in the soil over the years, it tries to seep into the foundation walls, further causing them to age and deteriorate.
