If you own a driveway or parking lot in the Lower Mainland, you already know our winters are less about deep snow and more about weeks of steady rain, with the occasional cold snap in between. That combination is hard on asphalt. Water gets into small cracks, temperatures drop overnight, and by spring a hairline crack has turned into a pothole.
The good news is that most winter pavement damage can be prevented. A few hours of attention this fall can save you from major repairs next year.
Why Winter Is Tough on Asphalt
Asphalt is flexible, which is why it handles our climate better than many alternatives. But it still has weak points:
- Water infiltration. Rain seeps through cracks into the base layer and softens the ground beneath the pavement.
- Freeze-thaw cycles. Water that freezes expands and widens the crack. When it thaws, the gap is bigger and ready to take in more water.
- Standing water. Puddles that sit on the surface for days wear away the asphalt binder and weaken the pavement.
- Leaves and debris. Wet leaves trap moisture against the surface and can stain it.
Step 1: Walk the Property and Look for Damage
Start with a slow walk around your driveway or lot. Look for:
- Hairline cracks and wider cracks
- Potholes or low spots that collect water
- Crumbling edges
- Faded, dry-looking patches of asphalt
- Areas where water doesn't drain away
Take photos so you can compare them in spring. Small problems are far cheaper to fix than large ones, and a quick inspection now tells you whether you need a simple repair or something bigger.
Step 2: Seal Cracks Before the Rain Gets Worse
Crack sealing is one of the most effective ways to protect asphalt through winter. Sealing keeps water out of the base and stops cracks from spreading. Cracks should be cleaned and dry before sealing, so it's best to do this during a dry spell in early fall rather than waiting for the wettest weeks of the year.
If cracks are wide, connected in a web pattern, or sitting over sunken areas, sealing alone may not be enough. That usually points to a base problem. Our asphalt paving maintenance services cover patching, crack sealing and repairs for exactly these situations.
Step 3: Patch Potholes Right Away
A pothole will not stay small. Every rainfall and every vehicle that drives over it makes it bigger. Patching it before winter keeps the damage from reaching the base, where repairs become more involved and more expensive.
Step 4: Fix Drainage Problems
Water is the biggest enemy of asphalt. If you see puddles that stay for a day or more after rain, treat that as a warning sign:
- Clear leaves and debris from gutters, downspouts and drains
- Make sure downspouts direct water away from the pavement
- Note low spots where water pools, as these may need regrading or resurfacing
Drainage issues are one of the main reasons pavement fails early, so they're worth addressing even if the surface still looks fine.
Step 5: Consider Sealcoating
Sealcoating adds a protective layer that helps shed water and slows down oxidation and wear. It works best on pavement that is still structurally sound, with only minor surface wear or fading. It is a preventive measure, not a fix for damaged asphalt, so cracks and potholes should be repaired first.
As a general guide, sealcoating is recommended every two to three years, though heavy traffic or harsh exposure may shorten that.
Step 6: Keep the Surface Clean
Sweep or blow off leaves, dirt and debris regularly through the fall. Debris holds moisture against the pavement and can clog drains. Also be careful with oil and fuel leaks, which soften asphalt over time.
Step 7: Be Careful with Snow and Ice Removal
When we do get snow or ice, avoid metal shovels and blades that can gouge the surface. For ice, use salt or de-icer sparingly. For more advice on this, see our blog on salting your driveway. Property managers can also look into our snow removal and salting services for commercial lots.
When Repairs Aren't Enough
Sometimes maintenance can only do so much. You may need to repave if you see:
- Widespread cracking across large areas
- Sinking or alligator-patterned (interconnected) cracking
- Drainage problems that keep returning after repairs
- Repeated patching in the same spots
In these cases the base has usually failed, and a new surface over a weak base won't last. A proper evaluation will tell you whether you need repairs or full replacement. If you do need a new surface, our residential asphalt paving and commercial asphalt paving crews can assess it and give you a straightforward recommendation.
