Key Reasons to Raise Your Sunken Slab
SAFETY. Trip hazards can harm you and allows your property to be open to unwanted liability. Don’t wait until it’s TOO LATE!
COST. In some cases, nearly 1/2 the cost of replacement!
TIME. Polyurethane concrete lifting is ready to use immediately. Jobs are completed in hours, NOT days!
TROUBLE-FREE. No need to tear out old concrete with noisy machinery, no damage to the yard or surrounding areas. No need to worry about rain delaying the project.
BE GREEN. Save your current concrete from being torn out and deposited in a landfill.
When we are called to assist a home owner with a free estimate for concrete leveling, they are often happily surprised they can have perfectly aligned concrete again, in a matter of minutes, saving them time and money.
That’s because when compared to concrete replacement, the process of raising concrete with polyurethane foam is inexpensive (compared to the alternatives), and is exponentially faster than replacing the concrete.
Why does concrete settle?
Poor Soil Conditions: Clay-rich soils are ‘elastic.’ They expand and contract with moisture content. As soils become saturated with water, the clay expands and loses strength. This condition allows slabs to sink just like standing in wet mud. This can occur from heavy rains, melting snow or plumbing leaks.
Poor Compaction: Many homes are built on backfilled soils. If the soil is not compacted correctly, backfill will slowly and unevenly compact, sometimes over a period of a year, allowing slabs to settle.
Tree Roots: Trees and large shrubs can consume up to 30 gallons of water a day. If located near concrete, the loss of water in the soil will make the soil contract and can cause the slabs to settle.
Poor Drainage: Improper drainage can cause soil instabilityby creating areas of saturated soils allowing the slabs to settle. Poor drainage can be typical to the area, or as minor as a misplaced down spout. Many homeowners make the mistake of waiting until the problem worsens or spend 2x as much on replacing the concrete. Until the problem is fixed your home remains at RISK.

Steps to Raising Concrete
Most concrete raising jobs will take between one to two (1-2) hours—start to finish—and your concrete will be ready for use immediately upon completion!
Injection holes are strategically drilled around the areas where the concrete is sunken and requires lifting.
Once everything is prepped and the hose and materials are in place, the polyurethane foam is injected through the holes which fills the space underneath the concrete slab, using the concrete slab itself to drive the foam into the crevices, thereby lifting the concrete back to its original, correct level.
Upon completion of leveling the concrete, the injection hole(s) are filled discretely with new cement, allowing you to use your surface immediately.
Polyurethane Concrete Raising uses a foam material that is injected under the slab. When the components of this material are mixed, a reaction causes the material to expand. This expanded foam fills any voids beneath the slab and raises concrete.
This material will never lose density, is permanent and weighs only about 2 lbs. per cubic foot.
