What Are the Causes of Humps in Basement Floor?

1. Hydrostatic pressure: This occurs when water builds up around the foundation walls of your home and pushes the floor upward. This can happen during heavy rains or when the water table is high.

2. Frost heave: This occurs when water seeps into the soil beneath your basement floor and freezes, causing the soil to expand. When the soil thaws, it contracts and pulls the floor up. Frost heave is most common in cold climates.

3. Underlying tree roots: As tree roots grow, they can put pressure on the foundation of your home and cause the floor to rise.

4. Structural damage: If the foundation of your home is damaged, it can cause the floor to hump. This can be caused by a variety of factors, such as earthquakes, flooding, or improper construction.

5. Heaving soil: Heaving soil is soil that expands when it gets wet and contracts when it dries out. This can cause the floor to hump and create uneven surfaces.

6. Faulty construction: Improper construction techniques, such as inadequate support beams or insufficient footings, can also lead to humps in the basement floor.

If you notice a hump in your basement floor, it's important to have it inspected by a qualified professional to determine the cause and recommend the best course of action.
