01 — About

More than a contractor.

Delso Structures is the formwork division of the Delso Group of Companies. We don't sub out the hard work — our own crews form the foundation of every concrete project we touch, on time and on budget.

Delso Structures contributes to major concrete construction projects across Ontario. With over 20 years of combined experience in concrete forming, our team brings a hands-on understanding of what complex projects take to complete.

We've amassed a wide range of experience in concrete forming systems — from conventional handset to engineered table forms, climbing systems for high-rise, and one-off custom solutions for civil infrastructure.

As part of our services, we also provide a full scope of waterproofing — foundation wall systems, hot-rubberized waterproofing, traffic deck coatings, mechanical room waterproofing, and more.

With the full support of the Delso Group, we exceed project requirements at every scale.
