To fix a sinkhole in a concrete driveway, the first step is to identify the cause of the sinkhole. The most common causes include heavy rains and a burrowed gopher. Previous owners of the property may have filled in the gopher’s hole but did not complete the project. This caused the concrete to collapse and cause the hole. You will need a pump to fix the problem.
If you have a small sinkhole, you can repair it yourself using an asphalt patch and sealant. If the sinkhole is large, you will need to cut away a portion of the driveway and replace it with a new one. In larger problems, you may need to install architectural supports or protect underground wiring. The area around the hole should be repaired to finish grade. You can then cap the driveway with a blacktop.
Once the hole is cleaned out, you can start patching it. If you’re working on a larger problem, you may need to use architectural supports or protection to avoid damaging the surrounding area. Then, use a hammer and pack down a section of asphalt and fill in the hole. If the hole is larger than a patch can fill, you may need to remove a section of the driveway.
