What causes concrete slabs to sink?

Erosion is a common cause of sunken concrete. Erosion washes away soil from under your concrete foundation, creating a void or space under the concrete slab. Your concrete slab can begin to sink in areas where the soil has been washed out.
Clogged gutters, downspouts that are not installed correctly, and poor yard drainage can make erosion worse.
A heavy load, such as an RV that’s kept in your driveway, can cause sections of the driveway to sink and crack over time.
If you have a newer home with a sinking concrete slabs, it could be because the ground around the house is settling or the base of the concrete slab was not compacted properly.
A sinking concrete near your home can lead to foundation cracks and expensive damage over time.

how concrete Lifting and leveling works?

Polyurethane concrete lifting also called Slabjacking, Poly jacking, concrete raising and concrete leveling.

Polyurethane concrete lifting attempts to lift a sunken concrete slab by injecting Polyurethane foam through small holes into the concrete slab, effectively raising it up from below.

The following are the steps on how Concrete Lifting and Leveling works:

The slab jacking process generally begins with drilling 3/8″ holes into the concrete, strategically located to maximize lift.
Initial material injections will fill any under slab void space.
When the material is injected under a high pressure into the concrete slab, the air bubbles expands and the resin reacts and become solid foam.
During the injection, the material will expand in all directions and fill any voids in week soils under the slab causing the sub-soils to become more dense and stable.
Once the void space is filled, subsequent injections will start lifting the concrete immediately.
After the slabs are lifted, the access holes are patched and the work is complete.

The benefits of using Polyurethane Concrete lifting and Leveling

Cost Effective: cheaper than demolition, soil remediation, and slab replacement.
Quick Cure Time: typically, polyurethane cures within 15 minutes after injection. With this short time span, you’re able to walk the area, even on hot days.
Hydrophobic: specifically designed polyurethane can be used underwater or in wet conditions.
Strength: The foam will retain its structure and strength, reducing the possibility of new gaps or settlement.
Lightweight: concrete weighs 150 lbs. per cubic foot, where polyurethane weighs 3 lbs. per cubic foot (meaning it will not overburden your soil).
3/8″ Injection Holes: the injection holes for a polyurethane leveling are approximately the size of a dime. This allows for less visible patching.
Eco-friendly: Polyurethane foam is made in part from recycled and renewable materials. It won’t rot underground, nor will it pollute the surrounding soil and groundwater. The longevity of polyurethane foam also makes it less likely that property owners will have to repeat the repair process, helping them to conserve resources.
