How To Fix A Sinkhole In An Asphalt Driveway. Weird news columns are filled with those tales. 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.
Then, pour the concrete into the sinkhole. As mentioned, sometimes sinkholes can be caused by undetermined structural issues or there may be other problems at play that need to be addressed before the dip can. If your sinkhole is just a shallow depression, you may treat it like an alligator crack.
For edge repairs, install a board even with the edge to hold the asphalt in place while it sets.
After it’s cut, lay a block of wood on the soil at the edge of the driveway, shove a pry bar under the old asphalt, and pry against the wood block. A dip or depression in the asphalt can collect rain. Also, becuase of the coat and the prep work before the stamping the driveway should last twice as long as a regular asphalt as well as not crack. Build the foundation back up to the same level as the surrounding base, then fill it in with pothole patch.
