You spot a crumbling section or a nasty pothole on your driveway, and you know you have to deal with it before the winter freeze sets in. When you start looking at ways to fix it, you usually run into two main options: a quick surface patch or a full-depth removal and replacement. They both cost money, but they solve problems in entirely different ways.
What is a Surface Patch?
A surface patch, sometimes called a skin patch, is essentially laying a new layer of hot mix right over the damaged area. The crew cleans out the loose debris, applies a sticky tack coat, and lays down a couple of inches of asphalt to smooth things out.
- Low initial cost that does not break the bank
- Fast application taking less than an hour
- Decent appearance for light traffic
The problem here is that you are only treating the symptom. If your base has failed underneath, a surface patch is just putting a bandage on a broken bone.
What is a Full-Depth Patch?
A full-depth patch means we saw-cut around the damage, dig out the broken asphalt, and inspect the aggregate base layer underneath. If the sub-base is compromised—which happens often around Bristol, IN due to our clay soils and heavy moisture—we dig that out too, compact a fresh stone base, and lay new hot mix asphalt in thick structural lifts.
- Permanently fixes base failures and stops potholes from returning
- Engineered to handle heavy vehicles and winter snowplows
- Outlasts surface patches by many years
How They Compare in Northern Indiana
Up here in Elkhart County, our weather is brutal on pavement. We deal with heavy frost heaves and dozens of freeze-thaw cycles every single winter. Water gets into tiny cracks, freezes, expands, and wrecks a driveway from the bottom up.
If you choose a surface patch over a weak sub-base, water will still find its way underneath. By the time spring rolls around, that patch will likely crack around the edges, sink, or pop right out. All Things Asphalt Company sees homeowners spend money on cheap surface patches every couple of years, only to realize they spent more total cash than if they had just done a permanent fix the first time.
Our Recommendation
If you are dealing with a minor surface blemish where the underlying base is still rock solid, a skin patch can buy you some time. But if you have alligator cracking, sunken areas, or a pothole that came back after you filled it last year, do it once and do it right. Go with a full-depth patch. It costs more upfront, but it actually solves the root of the problem and stands up to our local winters.
