Sinking Patios, Driveways, Pool Decks and Other Slabs
A lot of Waynesboro and Tri-state area homeowners deal with sinking concrete. In our area, most homes are built on heavy and often soft clay soil, which consists mostly of very fine clay particles over limestone bedrock. This type of soil holds a lot of moisture, and this, unfortunately, can lead to issues with your concrete over time. When your slabs start to sink, you may be considering a replacement. However, if the damage isn’t too extreme, repairing and leveling your concrete with our sinking concrete repair service in Frederick may be a more affordable option.
What Causes Sinking Concrete?
The cause of sinking concrete comes down to the soil below it. If there’s not enough soil support for a heavy slab, or if your soil has a high clay content, your concrete is more prone to sinking and cracking.
Fluctuating Moisture Content
As we mentioned, most of the soil around our area has a very high clay content. This makes it really sticky and moldable when wet. So, when it rains, the clay soaks up as much water as possible and begins to swell. Then, as the soil dries out, it begins to shrink and can no longer support the pressure from the heavy concrete on top of it, causing your slabs to sink irregularly.
If your home was built on sandy soil, you may be dealing with soil washout. When rainwater flows beneath the slab, sandy soil is easily disrupted and can start to wash out with the water. This leaves voids beneath the slab and, because the heavy concrete no longer has adequate support, it will start to crack.
Poorly Compacted Soil
This is an issue that happens before your concrete is even poured. If the team installing your concrete didn’t compact the soil beneath it well enough before pouring, it will start to compact irregularly under the weight of the concrete over time. This will eventually lead to sinking and, in some cases, cracks in your concrete.
A Fast, Efficient Solution
PolyLEVEL is a fast, accurate way to re-level your sunken concrete. Our sinking concrete repair experts in Frederick simply inject it underneath the slab, so it can lift the concrete as it expands. Once it reaches the desired level, it hardens in place, filling the voids below the concrete and providing a solid structure to support it.
