Small cracks are where every driveway failure starts. In Cambridge, water gets into a crack, freezes overnight, expands, and pushes the asphalt apart. Do that a few dozen times every winter and a hairline crack becomes a pothole. Filling cracks early is the cheapest repair you can make on an asphalt driveway.

How asphalt crack filling works
- Clean out the crack: debris, weeds and loose material are removed so the filler bonds to solid asphalt.
- Fill with hot rubberized crack sealant: it stays flexible, so it moves with the pavement through freeze-thaw instead of popping out.
- Level and finish: the filled crack is smoothed flush with the surface so it won’t catch a snow shovel or plow.
- Seal the surface (optional): crack filling pairs best with driveway sealing, which protects the rest of the surface from water and UV.
Signs your driveway needs crack filling
- Thin cracks along the edges or down the middle of the driveway
- Grass or weeds growing through the asphalt
- Cracks that have widened since last spring
- Water pooling near cracks after rain
- A spider-web (alligator) pattern starting in one area. Fill it early, before it needs a full repair.
Why timing matters in Waterloo Region
Crack filling is done in dry weather, generally spring through fall. The best time is late summer or early fall, so cracks are sealed before the first hard freeze. If cracks have already become potholes or sunken areas, you need driveway repair instead.
Residential and commercial
Crack filling works for home driveways, laneways and commercial parking lots. For larger lots, routine crack filling is one of the lowest-cost ways to put off a full repave.
Crack filling FAQ
How long does crack filling last?
Hot rubberized sealant typically holds for a few seasons. Inspect your driveway every spring and touch up any new cracks.
Can I drive on it right away?
Hot-pour crack filler cures quickly. Most driveways can be used again the same day. Your contractor will confirm for your job.
Is crack filling the same as sealing?
No. Crack filling repairs individual cracks; sealing coats the whole surface. Most driveways benefit from both: fill first, then seal.
How much does it cost?
It depends on the total length and width of the cracks. See our driveway sealing cost guide or call for an exact free quote.
