How To Fix A Sinkhole In A Driveway. Driveway repair undoubtedly doesn't top anyone's list of favorite weekend activities, so when simon marks of luton, england, had an accident in his own driveway one saturday, he groaned at the thought of a ruined weekend. Then, you need to make sure you clean it out carefully, extracting all excess standing water, debris, tree branches, or broken off pieces of asphalt you might find under there.
Shovel soil into the hole until it is mounded a few inches (about 7 cm) above the surface. The property owner should layer in a few inches of dirt and tamp it down firmly. Clean loose dirt and debris out of the hole with a garden shovel, a trowel, or other suitable tool.
If the material in the hole is dry soil, you may want to use a garden hose to dampen it because the tar will not stick to dry dirt.
If your sinkhole is just a shallow depression, you may treat it like an alligator crack. The old asphalt will lift up and break off in sections. Using a pothole tamper or motorized plate compactor, condense and test the area underneath the hole to ensure its solid. If your driveway has dropped in a uniform way across the entire area you can think about adding a topper such as paving bricks or a resin coating to the required depth.
