When Interior Floors Start Settling
Interior concrete slabs - whether in basements or slab-on-grade homes - can settle just like exterior concrete. The difference is that interior settling often goes unnoticed until it becomes severe.

Signs of interior slab settlement:
- Floor slopes noticeably in one direction
- Cracks appearing in the concrete
- Doors sticking or not closing properly
- Water pooling in basement low spots
- Furniture sitting unevenly
Causes of Interior Slab Settlement
Interior slabs settle for several reasons:
- Soil consolidation over time under the weight of the slab
- Water infiltration washing away supporting soil
- Poor original compaction during construction
- Plumbing leaks eroding soil beneath the slab
- Root decay from trees that existed before construction
The Challenge of Interior Repairs
Traditional solutions for interior slab problems are extremely disruptive:
- Breaking out and replacing the concrete
- Excavating and re-compacting soil
- Living with construction mess for weeks
Our leveling approach works differently.

Our Interior Leveling Solution
We can lift and stabilize interior slabs with minimal disruption:
- Small holes drilled through the concrete (can often work through existing flooring)
- Limestone slurry injected to fill voids and lift the slab
- Precise leveling using laser measurement
- Holes patched and area cleaned
Most interior leveling projects are completed in one day.
Protecting Your Foundation
In slab-on-grade homes, a settling floor isn’t just uncomfortable - it indicates foundation problems that can affect:
- Structural integrity of the home
- Door and window alignment
- Wall crack development
- Resale value
Addressing the problem early prevents more costly repairs later.
Basement Floor Solutions
Basement floors often settle due to water intrusion washing soil out through cracks or drainage systems. We can:
- Level the sloped areas
- Fill the erosion voids
- Stabilize the soil beneath
- Address the root causes
