Polymer Coated Steel Tunnel Liner Plate Successfully Rehabilitates Failing Concrete Box Culvert
Located south of Lake Nipigon, on Highway 11 in East McKirdy, Ontario, a 108 year-old, cast-in-place (CIP) concrete box culvert beneath the highway was failing. A long-term solution was required to rehabilitate the aging structure and maintain vehicular access along this busy stretch of highway.
The Tunnel Liner Plates were delivered to the site on relatively small pallets that could easily be moved close to the mouth of the structure. This significantly reduced the distance materials needed to be carried and also shortened installation time. The plates were assembled into continuous rings, advancing the tunnel in 500 mm sections; in total, one hundred and eight Tunnel Liner Plate rings were used to complete the job. Rehabilitation of the CIP concrete box culvert was successfully completed in October, 2016. Polymer coated Tunnel Liner Plates provided a durable and cost-effective solution to this challenging rehabilitation. For more information contact: |
