Smuggler’s Notch ski resort, near Jeffersonville, VT, was established in 1956 and is New England’s fourth-largest resort area. It is built around Morse, Madonna, and Sterling mountains. Record storms in the Northeast, and the resulting record snowmelt, caused near-flooding at Smuggler’s Notch, and two 72-inch “boilerplate” culverts, each 130 feet long, were filled to near capacity with fast-moving water. They survived but were damaged; it was clear to managers that the culverts needed major rehabilitation before the next spring thaw.
So Smuggler’s Notch needed a trenchless rehabilitation solution that was structural, waterproof, and fast and that wouldn’t significantly reduce interior diameter. Ideally, it would also be cost effective compared to other methods. Fortunately, while reading a trade journal, Delaney saw an ad for Centri-Pipe, a centrifugally cast concrete pipe (CCCP) solution that is emerging as a best practice for large-diameter pipe in need of structural repair and waterproofing. It’s a technology created and refined by AP/M Permaform for use in manholes, and is now being used in horizontal pipe.
