As our drainage infrastructure continues to age, Capitol Tunneling realizes the need to rehabilitate these deteriorating structures. Recently we have undertaken several culvert rehabilitation projects to protect the structural integrity of the host pipe. Culvert rehabilitation covers a vast array of means and methods, and our crews have the documented experience to meet the special needs of this niche market. From slip-lining HDPE carrier pipes into deteriorating host pipes, to completely removing and replacing host structures trenchlessly, our crews are ready and able to do the work.

Recently, Capitol Tunneling was awarded an emergency contract from the Ohio Department of Transportation to remediate a 108” diameter multi-plate structure that had failed under the busy I-90 corridor in Elyria. The collapse had caused I-90 to start to slip and if the culvert was not repaired quickly, a total failure of the pipe and blockage of a major waterway was imminent. CTI crews mobilized to the site and stabilized the failed section of the culvert, then removed and replaced the damaged host pipe with a new tunnel liner plate capable of withstanding the loading. A paved invert was then poured for low flow and the health and safety of the traveling public on I-90 was restored.

In late 2012, the City of Ontario Ohio awarded a contract to Capitol Tunneling to install a HDPE slip-liner pipe into a failing 42” CMP culvert. CTI crews mobilized, prepared the site, installed the liner, and grouted the annulus in record time. The Snap-Tite Product was great to work with and we look forward to working together on additional projects.
