Piling & Shoring

Full Service

Excavation and Piling

Our comprehensive offering, including site services and design-build expertise, ensures an efficient and high quality project from the ground up.

Dufresne is more than a piling contractor. Thanks to our comprehensive capabilities, our team can undertake both excavation and piling/shoring, meaning you only have one contractor to manage. This allows you more efficient coordination of onsite activities when beginning your construction project. Not only does this provide more cost certainty, it can lead to efficiencies in time, as well as improvements in the quality of your project. Many customers trust us to spot challenges which might otherwise be overlooked.

Market Leader

Since 1967, we have built a reputation as a market leader in excavation and piling in Eastern Ontario, with an established local presence and solid track record. We are CWB certified so you can be assured of quality work.

Design-Build

Dufresne’s group of professionals brings their design expertise to every project, helping customers maximize the use of their property. Our team will fine tune your design where appropriate, ensuring constructability and material availability for your project. Developers often turn to us to provide our recommendations to their design engineers at the start of a project.

Wide-Ranging Sector Experience

With experience in unique projects such as the West Block Rehabilitation Project on Parliament Hill, through to demanding heavy civil projects such as bridges and the LRT, our team can support you in any construction project. We deliver services to customers in the construction, land development, real estate, industrial, commercial, institutional, provincial, municipal and heavy civil sectors.
