Driveway damage can be frustrating, but often it is repairable. Knowing when to repair and when to replace is important.
Repeated Pothole and Deep Crack Formation
A single pothole or crack doesn't necessarily mean that you need to replace your driveway. The problem is when the paving keeps developing new potholes or deep cracks. While shallow damage and cracks are typically only an appearance issue that won't worsen as long as they are patched, deeper damage can penetrate into the base and compromise the integrity of the entire driveway. If this damage keeps happening, it likely indicates that the base is already failing. Trying to repair constant deep damage is a waste of money since the only real solution is to rebuild the entire drive.
Ongoing Drainage Issues or Sinking
A constantly flooding driveway is systemic of a deeper underlying issue with the drainage. In some cases, the problem can be repaired with the installation of a drain to route the water off the drain, but not always. If the drainage issues have developed over time, this indicates that the driveway is sinking. Sinking is often a result of a failing base that is either collapsing or being washed out from below. The only solution at this point is to have the old driveway removed so the base can be rebuilt.
Excessive Crumbling Along the Edges
A few cracks along the edge of a paved driveway are normal as the paving ages, particularly if you every drive right along the edge. Excessive crumbling is a problem, though, as it indicates that the paving is failing due to its age. As the crumbling continues, a web of cracks will begin to spread from the edges over the entire driveway surface. Eventually, the missing paving along the edge will allow water incursion into the base material, leading to washouts. Although crumbling edges may not mean you need an immediate replacement, it is time to start planning for a new drive.
Age That Is Measured In Decades
Most driveways can last for two to three decades, depending on the material, maintenance, and soil structure. If your driveway has passed the two-decade mark in age, it simply may not make sense to spend money on repairs since it is likely approaching the time to replace it. It's always a good idea to consult with a professional paving contractor before making any repairs to an older driveway. Your money may be better spent on replacement.
