Types of Basement Damage in Sumter

Common Causes of your Basement Problems in Sumter

Expansive Soil

If your home is built on clay-heavy soil, it may expand when wet and shrink during dry spells. This constant movement puts pressure on your basement walls, potentially causing cracks and structural damage.

Climate Conditions

Heavy rains or drought can cause soil movement, leading to cracks or water intrusion in your basement. Basement repair addresses these issues, protecting your home and ensuring a dry, stable space.

Hydrostatic Pressure

When water collects around your foundation, it creates hydrostatic pressure that pushes against your basement walls and floor. This pressure can lead to cracks, leaks, and water damage.

Poor Drainage Systems

Without proper drainage, water pools near your foundation instead of being directed away. This can seep into your basement, causing moisture problems and structural weakening.

Foundation Weaknesses

Over time, natural settling or construction issues can cause cracks in your foundation. These openings allow water to enter your basement, leading to further problems if not addressed.
