Span Support Segment Grout Placement:
Victoria’s Johnson Street Bridge is a draw-bridge providing clearance for boat traffic. It is Canada’s largest single-leaf bascule bridge and is subject to nine million pounds loading. The responsible engineering firm in New York had an existing good relationship with ITW Performance Polymers and as the Exclusive Western Canadian Distributor for ITW Chockfast Products, Chinook Industrial was brought in on this project.
Key requirements of the project included:
- Grout placement expertise in unique applications
- Flexibility to adapt and change as the project moved forward
Chockfast Red was selected for grouting in Equalizer Bases, Span Support Segments and Span Operating Machinery Support Baseplate. This unique application required imagination backed with solid installation experience and technical knowledge to ensure this one-of-a-kind project was completed successfully.
Chinook was selected for all these capabilities. Chinook was consulted in the planning phase of this project. Presented with the engineering specifications and practical considerations required to address the actual pour characteristics, Chinook was asked for a recommendation.
Mock-ups were prepared at site for sample pours to determine effectiveness of planned pour methodology. Once approved, Chinook Field Services personnel attended at site and completed the installation of Chockfast Red. We also insured that cube molds were provided for Q/C Testing.
For Compressive Strength Testing and Reporting, Chinook can provide 2” Test Cube Mold rental and if required can have these tested and provide testing reports. When a project is unusual or one-of-a-kind, Chinook can provide installation solutions.
Chockfast Red is a three-component, high strength, 100% solids, epoxy grouting compound used to grout large machinery and to support soleplates in all types of foundations. Chockfast Red has an extremely high compressive strength. This along with negligible shrinkage makes it ideal for installing critically aligned machinery within very close tolerances.
Design Considerations
Chockfast Red is quick curing, relative to cement grouts, but the cure is thermally gentle. This enables thick pours to be made without causing the stress cracks often associated with hot-curing epoxy grouts.
