Carignan is a small, predominantly residential city in the Vallée-du-Richelieu Regional County Municipality (MRC), adjacent to Chambly, located approximately 30 km to the east of our Sherrington base. With its 10,000 residents and its character halfway between suburb and countryside, Carignan has numerous single-family home developments with medium-length paved driveways. The area is crossed by Route 112 and the L’Acadie River, creating particular conditions for the maintenance of parking lots and private driveways.
Why seal the cracks in your asphalt in Carignan ?
Asphalt in Carignan undergoes the same climatic stresses as the rest of Montérégie : 60 to 90 freeze-thaw cycles per year, intense winter salting on main arteries, and summer sun exposure that oxidizes bituminous binders. Every untreated crack lets in water that freezes, expands by approximately 9 %, and shatters the pavement structure. After 2 or 3 ignored winters, a simple crack becomes a pothole, and what would have cost a few dollars to seal may now require several hundred dollars of patching.
Recent residential developments in Carignan (less than 15 years old) often feature HL3 asphalt driveways that are now reaching the critical age when the first cracks appear. This is exactly the moment when preventive sealing offers the best cost-benefit ratio : the pavement is still sound and can easily be protected for another decade.

We use exclusively hot-applied polymer-modified bitumen crack sealing conforming to MTQ 14501 standard, with Crafco 522 sealant approved by the Quebec Ministry of Transportation (MTQ).
- Inspection and mapping of all cracks.
- High-pressure compressed air cleaning.
- Heating the crack edges with a propane torch.
- Application of sealant heated to 190 °C.
