Since 1987, the Delso Group has built its reputation on quality workmanship, on-schedule delivery, and a hands-on approach to the most demanding concrete projects across Southern Ontario.
We're refreshing our online home — a new website is on the way. While we put the finishing touches in place, the divisions below are open for business and ready to take your call.
Each division operates as a specialist in its field — but draws on the combined experience, in-house capability, and project discipline of the entire Delso Group. New site or not, we're ready to talk about your project.
Formwork specialists for low-rise to high-rise, civil infrastructure, and sewer & watermain projects.
Founded 1952. Leading installer of resinous epoxy flooring and wall systems for cleanroom and industrial environments.
Concrete structure rehabilitation. Hydrodemolition, parking garages, treatment plants, and complex restoration.
More than contractors — the Delso Group brings a hands-on, senior-led approach to every project. We act as strategic partners to owners, developers, and engineering teams.
Our crews are fully skilled and in-house. We don't sub out the hard work. From early constructability analysis through final coatings, we own the schedule and we own the result.
That's how we've earned our reputation across nearly four decades of building Southern Ontario.
