Part of what allows us to run all jobs smoothly is our superior maintenance division. We also have our own Motor Vehicle Inspection Station on site, which is certified to inspect and service trailers and motor vehicles. The shop is attached to our main office located in Chelmsford, Ontario, directly off Highway 144 North. The shop itself is 6,000 square feet, has three bays, a stocked inventory room and fully certified mechanics on call 24 hours a day. Within the shop facility we service all our trucks, trailers, crushers, and heavy equipment. Having our own shop means that our equipment is kept in outstanding mechanical condition and helps keep down time to a minimum.

Our shop foreman is both a certified heavy duty equipment mechanic and a truck and coach technician who works extremely hard at keeping our yellow iron, trucks, and trailers in the best possible mechanical condition at all times. This in turn benefits you, the customer. See the difference quality and pride makes.


Our team is innovative, knowledgeable, and experienced in such diverse fields as: transportation, general construction, custom crushing, excavation works, lumber and logging, road building, and aggregate operations. We’ve also completed many specialized projects. Each and every client and project, regardless of size or localization, has contributed to our wide range of expertise and here we thank you.
