Beauharnois is a historic industrial city in the Beauharnois-Salaberry Regional County Municipality (MRC), located approximately 35 km to the west of our base in Sherrington. With around 13,000 residents and a territory that encompasses several formerly merged villages, Beauharnois features a mix of traditional residential neighbourhoods, industrial facilities (including the Hydro-Québec hydroelectric generating station) and commercial sectors along Route 236.
Why seal the cracks in your asphalt in Beauharnois?
Asphalt in Beauharnois faces the same climate stresses as the rest of the South Shore of Montreal: 60 to 90 freeze-thaw cycles per year, heavy winter salting on main roads, and summer sun exposure that oxidizes bituminous binders. Every untreated crack lets in water that freezes, expands, and breaks apart the paving structure. See our article on freeze-thaw cycles in Quebec for a detailed explanation of the mechanism.
The proximity of the St. Lawrence River and the Beauharnois Canal exposes parking lots in the waterfront area to particular moisture conditions in spring. Annual preventive sealing is often recommended for these sites rather than a biennial maintenance schedule.
Our 5-step process
We use exclusively hot-applied polymer-modified bitumen crack sealing compliant with MTQ 14501, with the Crafco 522 sealant approved by the Quebec Ministry of Transportation (MTQ).
- Inspection and mapping of cracks.
- High-pressure compressed air cleaning.
- Heating of crack edges with a propane torch.
- Application of sealant heated to 190 °C.
- Finishing and return to service within 30 minutes.

Frequently Asked Questions — Beauharnois
Do you travel to Beauharnois despite the distance from Sherrington?
Yes, Beauharnois is an important municipality within our extended service area. We schedule our visits to Beauharnois by grouping several jobs on the same day when possible, which allows us to maintain competitive rates. For residential jobs, we typically work with 2 to 3 weeks’ notice in order to combine with other work in the area.
Do you offer an annual maintenance programme for commercial properties and condominiums in Beauharnois?
Yes. Our commercial maintenance programme includes spring and fall inspections, crack sealing, and repair of small potholes. For property managers, see also our annual maintenance calendar and our article on the ROI of an asphalt maintenance programme.
Do you offer after-hours work for commercial clients in Beauharnois?
Yes, particularly for high-traffic commercial sites. An hourly surcharge of 25–35 % applies, but the absence of any impact on customers more than justifies this additional cost. See our article on mistakes to avoid in commercial parking lot management.
What product do you use for sealing?
Exclusively MTQ 14501-approved products, primarily Crafco 522 as our standard and Dynapave D-9000 as an alternative. Both are approved for public works contracts in Quebec.
Are you RBQ-licensed and insured?
Yes. L’Équipe Marcil inc holds RBQ licence 5624-8867-01, renewed annually, with civil liability insurance covering all our jobs in Beauharnois and throughout Montérégie.
