Sinking concrete can be a serious problem. One concrete characteristic that can cause problems is the weight of the material –about 150lbs. per cubic foot. Sometimes the soil beneath a concrete element doesn’t have sufficient load-bearing capacity to support the material and the static loads imposed on the concrete. When this happens, all or part of the slab will sink.
Settled or sunken concrete is usually a serious problem. Sunken sidewalks and pool surrounds pose a safety hazard. A concrete factory floor that cracks and sinks in one area can make the building unusable. The same goes for an airport runway.
Concrete leveling applications will work for the following sunken or settled concrete problems
- Concrete sidewalks & steps
- Interior floor slabs
- Concrete pool decks or pool surrounds
- Concrete patios & landings
- Sunrooms with concrete floors
- Concrete driveways
- Concrete roadways & parking areas
- Airport runways
- Roadways including Bridge approaches
- Rail Crossings
Concrete leveling can help prevent expensive demolition and reconstruction work. One solution to sunken concrete is to demolish and remove the slab or slab sections that have settled. But this necessitates building new formwork, installing proper reinforcement, pouring fresh concrete and waiting for new flatwork to harden and cure. A less costly and more expedient solution involves using concrete leveling techniques to raise the sunken concrete back to its proper level.
The terminology associated with concrete leveling can be confusing. Some terms (like slab jacking and slab raising) are generic. Others refer to specific techniques. Mud jacking is used both ways: to describe concrete leveling in general, and to describe a particular slab jacking technique.
Concrete Lifting vs. Replacement
- Costs less: Concrete lifting costs less than concrete replacement.
- Faster installation: Full weight-bearing function possible within a short time compared to replacement.
- Less mess: There is no need to demolish concrete and no damage to landscaping.
- Environmentally-friendly: Removed concrete often ends up in landfill; with concrete lifting there is no waste.
- Preventative: Fills voids to prevent erosion and further damage to concrete caused by animals and insects. Also helps stabilize soil.
- Improves safety: Eliminate trip hazards and prevent personal injury or possible lawsuits from uneven steps or walkways.
Foam leveling is a smart choice for residential & commercial applications.
FAQs
-
What is concrete lifting?
Concrete lifting is a process that raises sunken or settled concrete slabs by injecting material beneath them. This restores the slab to its original position without needing to replace it.
-
How is concrete lifting different from concrete replacement?
Concrete lifting is faster, less expensive, and far less messy than full slab replacement. It avoids demolition, reduces waste, and causes minimal disruption to surrounding landscaping or structures.
-
What causes concrete to sink or settle?
Concrete usually sinks when the soil beneath it can’t support the weight—often due to erosion, moisture changes, or poor soil compaction during construction.
-
Is foam leveling better than traditional mud jacking?
Yes. Foam leveling is often preferred for its lightweight material, quick curing time, and ability to reach small voids. It’s ideal for both residential and commercial properties.
-
How long does concrete lifting take?
Most projects are completed in just a few hours, and the concrete surface is usually ready for full use the same day—unlike replacement, which can take days to cure.
