Slab Cracks
What Do Slab Cracks Mean?
Slab cracks are more than cosmetic concerns—they are often early warning signs of foundation movement. In regions like Ohio, Pennsylvania, and West Virginia, dramatic seasonal changes cause the soil beneath your home to expand during wet, humid periods and shrink during dry or freezing conditions. This continual movement places stress on the foundation and can lead to cracking, instability, and structural damage.
Slab cracks frequently appear alongside other signs of foundation issues, including bowing walls, leaning chimneys, sticking windows and doors, and cracking drywall. While cosmetic repairs may temporarily hide the problem, they do not address the root cause. The professionals at Matthews Wall Anchor & Waterproofing Services can evaluate the entire foundation and provide the right long-term solution using industry-leading products from Earth Contact Products (ECP).
Understanding the Causes of Slab Cracks
Slab cracks develop for several reasons, many of which are tied to soil movement and foundation instability. Common causes include:
- Expanding and shrinking soil due to seasonal temperature and moisture changes
- Hydrostatic pressure pushing against the slab during periods of heavy rainfall
- Soil pulling away from the foundation during dry or freezing conditions
- Uneven settlement beneath the slab caused by shifting or poorly compacted soils
- Moisture imbalance under or around the home, leading to soil instability
- Long-term wear and structural stress, especially in older homes
These issues weaken the foundation and lead to slab cracks that will continue to worsen without proper stabilization.

Foundation Underpinning with Helical or Push Piers
Shifting soil and seasonal climate conditions in Ohio, Pennsylvania, and West Virginia can cause slab cracks as your home settles. Matthews Wall Anchor & Waterproofing Services installs ECP helical piers and push piers to stabilize and lift the foundation beneath cracked slabs. Underpinning solutions help:
- Support and re-level settled areas of the foundation
- Prevent slab cracks from widening or reoccurring
- Transfer structural weight to deep, stable soil layers

If slab cracks are linked to lateral soil pressure or shifting foundation walls, Matthews Wall Anchor may install wall anchors to reinforce and stabilize the affected walls. These systems:
- Strengthen cracked or displaced foundation walls
