Slab jacking is a concrete repair technique used to lift and level sunken slabs by injecting a stabilizing material beneath the concrete. As the material fills the void beneath the slab, it gradually lifts the concrete back to its original position.
This method is commonly used for:
- Driveways and sidewalks
- Garage and basement floors
- Patio and outdoor slabs
- Walkways and entryways
- Concrete Surfaces Around Foundations
Slab jacking restores the functionality and appearance of concrete without the cost and disruption of full replacement.
Signs You May Need Slab Jacking
Concrete settling often happens slowly, but some warning signs indicate that a professional slab lift may be necessary.
Common signs include:
- Uneven or sloping concrete surfaces
- Visible cracks in concrete slab
- Water accumulation near foundations or walkways
- Dangers of traveling on sidewalks or driveways
- Gap formation between the slab and surrounding structures
Addressing these issues quickly can prevent further soil erosion and structural complications.
Why Concrete Slabs Sink
Concrete slabs depend on the soil beneath them for support. When that soil becomes unstable, the slab can settle or bow.
Common causes of slab settlement include:
- Soil erosion due to heavy rain or poor drainage
- Improper soil compaction during construction
- Expanded clay that shrinks and swells with changes in moisture
- Underground pipeline leak
- Natural land settlement over time
Professional slab jacking corrects both the surface problem and the underlying void that caused the slab to sink.
How Robbins Foundation Systems Performs Slab Jacking
Robbins Foundation Systems uses a careful and systematic approach to ensure that the concrete is lifted evenly and safely.
Monitoring and evaluation
Technicians check the condition of the slab and surrounding soil to confirm that slab jacking is the proper repair method.
Strategic injection point
Small holes are drilled in specific areas of the slab to allow lifting material to be inserted beneath the concrete.
Controlled lifting process
A special mix is poured under the slab, filling the voids and gradually bringing the concrete back to a level position.
Surface restoration
Once the slab is properly aligned, the holes are sealed and the concrete surface is ready for normal use.
Benefits of Professional Slab Jacking

Frequently Asked Questions
How long does slab jacking last?
When performed correctly, slab jacking can last for many years because the material used beneath the slab provides stable support.
Is slab jacking better than replacing concrete?
In many cases, yes. Slab jacking restores existing concrete at a much lower cost and with less disruption than replacement.
How long does slab jacking take?
Most slab jacking projects can be completed within a few hours depending on the size of the area.
