Engineering Certainty for Complex Urban Builds

Drill Rig and WJ Operative Closeup Toronto Sept 2020 1

Project overview

Drill rigs and wellpoints on site

Residential and commercial developments form a core part of WJ Canada’s expertise. From high-rise condominiums to mixed-use commercial projects, our dewatering solutions have supported safe, efficient excavation for some of Toronto’s most ambitious builds, as well as projects overseas.

But not every job begins under ideal conditions. At one downtown Toronto site, WJ Canada was called in to deliver an emergency remedial solution when the existing dewatering system could not achieve the required drawdown for the final stages of a multi-level excavation.

Location

Toronto, Ontario

Emergency Call-Out, Expert Response

The original contractor had installed an external perimeter dewatering system, complemented by localized internal wells. However, the system struggled to control groundwater effectively as excavation deepened, putting timelines and structural stability at risk.

WJ Canada was engaged to design and install a targeted solution that could achieve the required drawdown quickly and reliably, ensuring construction could continue with confidence.

Innovative Wellpoint System

Our specialists deployed WJ’s unique wellpoint dewatering system, supported by our specialised drilling methods. This included installing wellpoints directly through caisson piles; a challenging task requiring precision equipment and expert handling.

Thanks to our compact drilling rigs, we were able to access tight, restricted spaces that would have been impossible with conventional equipment. This adaptability proved critical to addressing the site’s unique challenges without disrupting ongoing works.

Successfully Dewatered

The result was a stable, dry excavation that met the project’s requirements. WJ Canada successfully delivered the drawdown needed to keep this multi-level development moving forward by applying engineering ingenuity and the right tools for the job.
