Recently, Brownline Canada provided gyro‑steering services for the installation of two parallel drainage lines under a cheese factory in Calgary. The exceptional accuracy of its Drillguide Gyro Steering Tool proved vital in completing the work exactly as planned and with minimal disruption.
In the heart of the city, the factory faced a full replacement of its aged waste drains embedded within the concrete slab.
The conventional method would have involved cutting open the slab, an ill-suited method in a food‑grade environment. The team chose instead to employ horizontal directional drilling (HDD) during a planned shutdown.
Brownline collaborated with Crossroads Coring Ltd. to execute the plan. Two parallel bores, each approximately 40m long and spaced around 1.45m apart, were carried out in tandem. Each bore was installed with a precise one percent grade to ensure proper flow. The site‑specific constraints demanded tight steering accuracy, and the Gyro Steering Tool delivered exactly that.
The first bore, using a 6‑inch pipe, commenced from the northern perimeter and connected into the existing drainage system on the southern side. Throughout the 40m drive, the steering technology maintained alignment and orientation with sub‑millimetre precision, avoiding any structural interference or operational interruption within the factory.
The second bore, using a 4‑inch pipe, was completed in close parallel to the first, matching the same slope and clearance. Thanks to the tool’s unmatched control, the team navigated both lines safely within the confined footprint without impeding factory workflow.
The project was executed efficiently and completed on schedule within the factory shutdown window. The result is a cost‑effective, minimally invasive drainage replacement that complies with the sanitation and operational standards of food production facilities.
This case demonstrates how Brownline’s Gyro Steering Tool is ideally suited to projects with tight timelines, strict hygiene requirements and the need to avoid heavy civil disruption.
