Châteauguay, with its 50,000 residents, is one of the most populous cities on the South Shore of Montreal and the administrative hub of the Montérégie region. Located approximately 30 km to the northwest of our base in Sherrington, the city developed around the mouth of the Châteauguay River and now features a dense mix of older residential neighbourhoods, new single-family developments, and busy commercial arteries such as boulevard Saint-Jean-Baptiste and Route 138. We work on everything from long driveways in the Haute-Rive and Vieux-Châteauguay sectors to parking lots serving downtown businesses and shopping centres.
Why seal the cracks in your asphalt in Châteauguay ?
Asphalt in Châteauguay is subject to the same weather stresses as the rest of Montérégie : 60 to 90 freeze-thaw cycles per year, heavy winter salting on main roads, and summer sun exposure that oxidizes the bituminous binder. Every untreated crack lets water in — water that freezes, expands by roughly 9 %, and breaks apart the pavement structure. After 2 or 3 neglected winters, a simple crack becomes a pothole, and what would have cost a few dollars to seal can now require several hundred dollars of patching.
Commercial parking lots in Châteauguay located near the river face a particular hydrological stress in spring, when rising water levels saturate road subgrades. Annual preventive sealing is generally more effective than biennial sealing for these sites.
Our 5-step process
We use exclusively hot-applied polymer-modified bitumen crack sealing compliant with MTQ 14501, using 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.
