Every Cambridge winter puts your asphalt driveway through the same punishing cycle: snow, melt, refreeze, plow, salt, repeat. Most driveway damage in Waterloo Region doesn’t come from traffic. It comes from water and salt working their way into the surface between November and March.
Freeze-thaw: how small cracks become potholes
Water seeps into cracks and gaps in the asphalt. When the temperature drops overnight, that water freezes and expands, pushing the crack wider. In Cambridge, temperatures swing above and below freezing many times each winter, so a hairline crack in November can be a pothole by April.
Road salt and de-icers
Salt tracked in from Hespeler Road, Highway 401 or your own sidewalk lowers the freezing point of water, which means more melt-refreeze cycles on your driveway’s surface. Salt residue also dries out unsealed asphalt over time, leaving it faded, brittle and grey.
Snow clearing
Plow blades and shovels catch on raised crack edges and crumbling borders. Damaged edges along the sides of the driveway are one of the most common things homeowners in Galt, Preston and Hespeler notice in spring.
How to protect your driveway
- Fill cracks in late summer or fall, before the first hard freeze, so water can’t get in.
- Seal the surface every 2–3 years. Sealer blocks water and salt from soaking into the asphalt.
- Fix potholes and failed areas early with proper driveway repair instead of waiting for them to spread.
- Shovel or plow carefully along the edges, and avoid piling salty snow on the driveway itself.
