The Broadway Subway Project is a 5.7 km extension of the Millennium Line, from VCC-Clark Station to Broadway and Arbutus. MSE precast is the proud supplier of the 5 kilometers of tunnel liner segments.


As Atlantic Industries Limited’s precast concrete supplier, we were excited to collaborate with AIL and develop these truly innovative Photo Art precast panels. Not only are these panels stunning to look at, they also meet the structural design requirements of the City of Calgary using a special proprietary concrete mix design.

MSE Precast Acquires Verti-Block Retaining Wall Product Line

In late-February of 2022, MSE Precast excitedly acquired the British Columbia and Alberta licensing rights for the Verti-Block Retaining Wall system.

Verti-Block can used in a gravity wall design for smaller wall heights, a geogrid friction connection design for larger wall heights and a geogrid positive connection design when seismic performance needs to be considered. The 2’ x 4’ x 3’ Engineered hollow core block style provides a lightweight handling weight for efficient and economical transportation and production rates.
