Reline Pipe Case Study

Print Back to case studies

The reline was a great success due to the teamwork between of Devron Pipe Sales, John Becchetti and the Regional road crew, along with CRL Campbell Construction Limited.  The reline of both culverts, grouting and reinstatement was completed in less than two days, with no traffic disruptions.  The flow capacity was increased from the original culverts, and there was no need to excavate the road, and the project came in on time and on budget!!


The Regional road crew had two existing culverts under the busy intersection at Hwy. 20 and Grimsby Road 5 in Smithville, Ontario.  The first culvert was a 27m long, 900mm Diameter CSP that required a 22 degree bend to align with the existing ditch under Hwy 20.  Digging this culvert up would have shortened the life of the recently paved roadway and would have required guide rail removal as part of the work.  The second culvert was a 22m long, 600mm diameter CSP under Grimsby Road 5.  Traditional replacement methods of the CSP culverts would have resulted in traffic disruption for several days.
