What Is Trenchless Utility Installation—and Why Is It the Preferred Solution for Some Projects?

Sandpiper is currently installing a new storm main that must cross busy Stewardson Way and the SkyTrain Expo Line in New Westminster—all while keeping one of the region's busiest transportation corridors fully operational. So how do you install a major underground utility without closing roads or disrupting rail service? The answer is Horizontal Directional Drilling (HDD). HDD is a trenchless construction method that allows underground utilities to be installed with little to no surface disruption. Rather than excavating long, open trenches through roadways, parking lots, retaining walls, or landscaped areas, crews work from strategically located entry and exit pits while specialized drilling equipment bores a precise path underground. https://www.sandpiper.bc.ca
