Driveway potholes are unsightly and can be damaging to your vehicle. Once you understand why the potholes appear and what you can do to fix them and prevent them, you can take better care of your driveway.
What does it mean if your asphalt driveway gets potholes?
Asphalt driveways typically develop potholes because of water intrusion into the asphalt. When the driveway develops cracks, water seeps into the asphalt and beneath the driveway, into the soil. When this happens, water saturates the ground and destabilizes the soil. This causes movement beneath the driveway base, resulting in more cracks and potholes. If this isn’t repaired, your asphalt driveway may begin to crumble. This issue may become more pronounced in winter when freeze thaw cycles cause water in the asphalt to freeze and expand, causing more potholes.
How can you repair your driveway and get rid of the potholes?
To repair the driveway on your own, clear out any debris from the pothole using a broom and a hose. Allow the pothole to dry, then use asphalt patch filler to fill the hole and tamp the patch filler down with a tamper. Once the patch is tamped, fill it with more asphalt patch and tamp again until the patch is even with the surface of the driveway. Then, allow the patch to cure according to the manufacturer’s instructions. For a more professional patch, call a reputable asphalt repair service in your area. Your asphalt repair contractor can use commercial-grade patching material to repair your driveway.
What can you do to prevent potholes in the future?
There are two things you must do to protect your asphalt driveway and prevent potholes.
- Repair cracks as soon as they appear. Asphalt cracks need to be filled as soon as they appear. To do this, clean out the cracks and remove any weeds. Sweep out the dirt, then wash them down with a strong jet of water from a hose, if necessary. Finally, lay down a bead of crack filler in each crack, and smooth the crack filler with a squeegee so that it’s flat on the asphalt. You can also
- Seal coat your asphalt on a regular basis. Seal coating is the process of covering your asphalt with a water resistant film that closes the pores of the driveway. Rain on a properly seal coated driveway will bead up on the surface of the asphalt without rolling off. Driveways need to be seal coated every few years, as soon as the driveway begins absorbing water when rain falls. You can seal coat your driveway with seal coat purchased at a home improvement center, or contact an asphalt repair service to do the seal coating for you. To seal coat the driveway on your own, clean the driveway with a hose and a broom, fill the cracks as described above, then use a squeegee to spread the seal coat on your driveway. Wear old clothes, because seal coat will ruin them.
