Challenges
-
Flow control and isolation:
maintain isolation from weather elements by creating a series of inertial weir walls behind lining segments to ensure optimal conditions for structural SIPP lining.
-
Cleaning of the CSP pipe segments:
50% debris levels with access to only 1 egress point. Hydraulic and mechanical equipment was used to remove metric tons of material from the CSP segment.
-
Infiltration mitigation and control:
Most of the invert portions of both of these sections had extreme pin holing and missing sections. The team used a variety of grouts and high strength cementitious materials to arrest all active infiltration within the CSP segments.
The Right Fit
- We had the opportunity to partner up with the successful proponent of the tender.
- We provided a custom solution incorporating SIPP technology, on a rigorous schedule.
- We are known for successful and consistent results in the industry, while tackling difficult projects.
Solution Review
Running lining (SIPP)
- 24/hrs per day schedule
- 36 days for installation
- 180,000lbs of material
The Right Solution
This project aimed to rehabilitate the CSP Culvert, which runs beneath one of Ontario’s major 400 series highways, leading to the Sarnia Border Crossing. In order to avoid disrupting the flow of goods and services along this corridor, a No Dig Solution was necessary.
