A pothole can render your driveway unsafe and unattractive. Fortunately, repairs are typically possible on an asphalt drive.
1. Surface Damage
Damages that later develop into potholes typically start small, usually as a depression or small crumbling divot in the paving. You can prevent the full formation of a pothole by repairing the surface damage before it becomes worse. Your repair service can clean out the low spot or divot. They then apply a hot asphalt patch, which bonds with the paving into a permanent repair. If there are many small surface damages, then sealcoating may be applied to help cover and protect the drive.
2. Shallow Potholes
Shallow potholes are those that have taken out a chunk of the paving but don't yet extend into the gravel base below the paving. These can be patched quite simply using the same hot asphalt technique that is used for surface damages. Your repair technician will first clean the rubble from the hole, then they will apply the hot patching compound.
3. Deep Potholes
A deep pothole extends well into the gravel base material of the driveway. These typically have a lot of rubble in the bottom and the wet season will almost always have standing water in the bottom. The repair technician must clean out and dry the pothole, and then new gravel is added and tamped down to repair the damaged base. Only after this is done can a hot patch be applied to fill the hole.
4. Wide Damage
Width can also affect the ideal repair technique. Wide potholes, whether shallow or deep, are more likely to have a failed patch. One way your repair service will combat this issue is by cutting out the entire section of damaged asphalt. This allows them to address any hidden issues with the base by simply rebuilding it and then reapplying fresh, undamaged asphalt on top. Although more involved than a spot patch, it is still less expensive than replacing the entire driveway.
Cracks are the precursors to potholes, but they can also form as a result of potholes and spread out radially from the initial hole. Cracks surrounding a pothole must be cleaned out and filled with a flexible asphalt patching compound. A fresh sealcoat is then typically applied to help smooth out the colour and to provide additional protection against weathering.

Everything changes as time goes on including concrete. In the past, for example, decorative concrete was a luxury, while now it is a mainstream staple, and I anticipate that concrete will change even more as the future rolls around. Hi, my name is Nicole, and I own several investment properties including one commercial building full of clients. As owner, I often have to pay concrete contractors to do work around my properties and even on the buildings themselves because I have concrete balconies on my commercial buildings. Twenty years ago, I knew nothing about concrete, but now, I know a lot, and I'm eager to share. Please explore!
