It happens, we sometimes see a sink or pothole right in the middle of them when everything else is perfect. While it can be hard to think of a solution yourself, there is something that can be done. Many who have this problem seek us out at Strictly level to fix this glaring eye sore through driveway raising. How does this problem happen? While it is difficult to tell with our lawn when it comes to uneven ground, a foundation problem will be quite visible wherever there is concrete.
It all comes down to the packing stone. Before the concrete is poured over a driveway, packing stone is laid beneath it. Most driveways sink because of an improperly packed foundation that lays underneath the concrete.
The driveway could also be sinking if an inadequate layer of packing stone was placed. This is an extremely common issue to see in homes built around the Chicago area since correct back filling is time consuming and the home builder wants to complete the home and sell it as fast as possible, especially in large track home developments.
Plus, it can take years until you start noticing the effects and at hat point the home builder is long and gone and the warranty has expired. Another cause for sinking concrete is water intrusion.
Water that is constantly intruding below the slab will overtime erode or wash away the soil or stone base. Clay rich soils will compound the effects of water intrusion and settling as the clay will freeze and expand during cold weather and shrink when it heats up creating voids. A common place we see water intrusion is where downspouts are discharging water right along the edge of a slab. Luckily restoring settled concrete is a quick and easy home repair. Contractors such Concrete Hero utilizes a process that involves drilling small holes and injecting an expanding polymer foam below the slab to fill the open voids and lift concrete back to the original height.
Over time cement and rock were added to the mix in an attempt to make it more durable. Its stability helps it to be a long-term solution and its durability is attractive in situations where it will be exposed to the elements.
This is why modern concrete raising has turned to it for raising sunken concrete driveways. It has many benefits with no real downside. Curing time is also substantially less than concrete or mud so the driveway can be used with a few hours of completing the work.
Or you can watch a video on our concrete raising process to get a better idea of how the process works. There are your three options for repairing your sinking driveway.
