We'll also provide a step-by-step guide on how to identify and fix cracks in your concrete slab foundation.Understanding Slab Foundation Cracks
A slab foundation is a type of foundation made from poured concrete that sits on top of the soil. Over time, the soil beneath the concrete can shift or settle unevenly, causing cracks in the slab. These cracks can be a sign of a larger issue, such as soil movement, tree roots, or an unstable foundation. There are two main types of slab foundation cracks:-
- Settlement cracks:
- These cracks develop when the ground beneath the concrete shifts or settles unevenly.
-
- Structural cracks:
- Wider and deeper structural cracks that may indicate more serious issues, such as tree roots or an unstable foundation.
