Piling it on – See how an old building technique is being given modern support for the Finch West light rail transit line (video)

Let’s dig into how piling work is an important part of the progress on the Finch West transit line, including an interesting video on how it works.

Talk about putting muscle into your work.

The Finch West Light Rail Transit (LRT) line is putting a modern take on a very reliable and old construction technique, and we have a video to show you more.

Piling is a construction technique that dates to ancient times when wooden piles dug into the ground reinforced bridges, forts, and buildings.

Today, crews use steel piles – beams – covered in concrete of various sizes to support new structures on the Finch West line.

To build a deep foundation, crews twist a steel casing attached to a rig into the ground to dig a hole. A steel pile is placed in the hole and covered with concrete.

See how Finch West Station and Humber College stop are being built using the piling method in the latest video.
