Why Concrete Sinks

Concrete can be poured, shaped and made into just about anything. But even though it’s incredibly strong, it’s not indestructible. So, when you see a driveway, pool deck or patio with broken, sunken slabs, there are reasons why these things happen.

What Lies Beneath

When your home was built, the contractor likely moved the soil around the building site resulting in poorly compacted soil. And even when it is compacted well, it’s never as stable as the original soil. Over time, this can cause voids to form and slabs to settle.

Another cause of soil failure is drought. During dry conditions or even just during periods of warm weather and low precipitation, the soil under your concrete will dry out and shrink, creating voids. The concrete above eventually cracks and sinks into these empty spaces; especially if any weight is placed on it.

When the rains return, as they always do here in Southern Florida, the water has an even easier pathway under the slab due to cracks and crevices left over from the dry period. And this wet, soft soil is just too weak to support the concrete above it. In the worst case, the soil erodes and washes away completely, leaving behind large voids that cannot support the weight of the concrete above.

Sunken concrete isn’t the end of the world, however. With the right technology, such as PolyLevel, and the right know-how, it can be lifted and leveled, so that it can be enjoyed as it was meant to be.

How We Repair Sunken Concrete Slabs with PolyLevel®

There are several traditional methods of raising concrete slabs, including spreading self-leveling compounds, mud jacking and pier installation. However, these methods can be very invasive and often don't fix the source of the problem.

PolyLevel® is the solution to these problems. This is how the PolyLevel® system works to raise your sunken slab:

  1. Very small sections of existing finished flooring are removed to access slab
  2. Penny sized holes are bored into the slab in each affected room
  3. Polyurethane foam is injected through holes, where it expands and raises the slab
  4. Foam is injected until the floor is level, reaching 90% rigidity within 30 minutes
  5. Finished flooring is restored over injection holes

With our system, you get the best solution for sunken concrete available without creating significant upheaval in your home.

Advantages of PolyLevel®

  • Non-invasive installation
  • Quick installation and cure time
  • Accurate lift for clean results
  • Adjustable for loads of all sizes
  • Environmentally friendly

PolyLevel Alternatives

When faced with broken, sunken and unsightly concrete, homeowners sometimes consider either going with mudjacking, which is the traditional way to lift concrete slabs, or total concrete replacement. 

PolyLevel vs. Mudjacking

Traditional concrete leveling methods such as mudjacking and slabjacking are messy, require a lot of downtime and often don't provide a long-term fix. Plus, they don’t address the reason why your concrete slabs sunk in the first place. In fact, by adding potentially a ton or more of extra weight on your already stressed soil, mudjacking can actually make the problem worse over time.

PolyLevel vs. Slab Replacement

Slab replacement can not only be expensive, but it can also be extremely disruptive because concrete slabs can take a long time to cure, rendering your driveway, patio or pool deck unusable for days or even weeks. And because total replacement involves pouring heavy new concrete over bad soil, it only delays future problems. Plus, unless you replace the entire driveway, deck or patio, slab replacement can leave an unsightly patchwork of old and new concrete.
