TransCanada successfully ran a large diameter gas pipeline below the St. Maurice River in 2008, but didn't anticipate failing slopes that would be left behind at areas cleared for the crossing construction. Sandy soils caused slides and deposited sediments along the natural bank.


Extreme slopes and remote access prohibited almost all solutions taht were considered- except ARMORMAX® 75! ARMORMAX® 75 was designed for rapid installation of lightweight materials on steep slopes. Pipeline workers were able to tether to the top of the slope and install mat and anchors with ease.

ARMORMAX® 75 provided a return to the pristine vegetated conditions that existed before the crossing construction enhancing the natural beauty of the area.
