Why is my concrete driveway rising?

One of the main causes of concrete rising is the presence of moisture beneath your driveway before the ground freezes. During winter, when water accumulates in the soil beneath the concrete, the ground freezes and expands. As a result, the expanding frozen soil pushes against the driveway, causing it to rise. This upward movement of the concrete can be a major problem for homeowners, leading to uneven surfaces and potential tripping hazards.

Why is my concrete slab rising?

Foundation upheaval is a common problem that occurs when the underlying soil expands or swells, causing the foundation or slab to move upward. This can happen due to an increase in moisture or freezing forces. It’s worth noting that heave is more likely to occur with slabs than foundations because they have less weight to resist the upward forces. If left unchecked, foundation upheaval can lead to serious structural damage, so it’s important to address the issue as soon as possible.
