The first thing to do when you notice cracks and sinking concrete slabs in your driveway is to do what you can to not make matters worse. That means that you shouldn’t put extra pressure on the driveway by parking on it or by waking over it more than you have to. That should give you plenty of time to repair the problem before the slab sinks further.
It’s also important to figure out what’s causing the cracks. If it’s an issue with the concrete itself, there’s little you can do but to replace it altogether. If the sinking and cracking are caused by a structural problem, you should contact experts to lift it and repair the soil beneath it.
There are a few ways to do so, but using PolyRenewal injections is proven to be the most effective in the long run and the least disruptive to your home.
