Versatile and Quickly Assembled
TRIO Wall Formwork System


PERI worked with PCL on supplying the ideal amount of TRIO for this 22 month, $300 million concrete pre-treatment facility.

Over 6,150 yd³ (4,700 m³) of concrete will be needed for this facility alone, with some walls 5.5 ft (1.68 m) thick and 26.2 ft (8 m) high. Self Compacting Concrete was required on the angled 35º crank walls.
All 66 wall pours were successfully formed with TRIO on this project.

    “I have worked with TRIO for 6 years and am a strong believer in the system. Its versatility and quick assembly were ideal for all the unique walls on this job. There is no doubt that we are currently exceeding our already tight deadlines as a result of using this system.”
