How to Know When to Reseal Your Driveway

Driveway Sealing OTtawaAsphalt is prone to cracks and crumbling as it expands and contracts, so a certain amount of that is expected over the course of a driveway’s life. But how do you know when cracking and crumbling warrants a re-sealing? Letting things go too long exposes you to the potential of a partial or complete re-paving of your driveway, but you also don’t want to pay for resealing too frequently. Find out exactly when a re-sealing is warranted with ProSeal Asphalt.


Asphalt Sealing OttawaCracks in driveways are formed from your asphalts natural expansion and contraction during hot and cold weather cycles. During periods of heat, your driveway will expand and allow moisture to penetrate the cracks and crevices of your driveway’s asphalt. When temperatures dip below freezing, this moisture will freeze and expand, placing your asphalt under pressure and widening the gaps and holes that comprise the texture of your driveway.

Identifying these cracks, and getting an impression of their size is the first step to determining if you need to call ProSeal to seal them. As a general rule, if you can squeeze a loonie into a crack, it’s time to give ProSeal a call. Left untreated, these gaps will become substantial, and as your car repeatedly drives over them, they will crumble. When this happens crack filling treatments will not be enough to fix them, and they will require a re-pave.

This happens because as they dry out, driveways become more susceptible to moisture penetration. If they don’t have sealant, they’ll take any moisture they can get, including water and the chemicals that drip from underneath your car. This exposes them to the problems associated with freeze-thaw cycles, diminishing their ability to weather the force of your car driving over them. High-traffic areas, and the edges of your driveway are especially prone to crumbling. Around the edges, your asphalt has nothing pushing on it to prevent pieces from falling off; and without sealant your driveway is considerably less able to take the beating your car gives it day after day.
