July Rehab News: Instituform wins $6.5M Contracts, CertainTeed replaces failing sewer

July 2010 Vol. 65 No. 7

The Village of Baldwin hired contractor Korte-Luitjohan Contractors Inc., Highland, IL, to install the gravity sewer main and build a new sewage lift station. The contractor used a Vermeer directional drill and a DCI Digitrak F2 Drill-Head Locator with target steering crew to make a 600-foot bore. The bore began at a depth of 14 feet and ended at a depth of 17 feet, meeting grade requirements all the way. The installation took eight days, and the installed pipe was then camera-tested for sags and deflections and passed with flying colors.

“Certa-Lok provides outstanding leak resistance and holds up to the rigors of pipe pullback in directional drilling installations,” says Steve Gross, director of R&D and technical services for CertainTeed’s Pipe business. “The pipe is easily assembled, without the need for time-consuming and expensive joint fusion. And, most importantly, Certa-Lok requires a much thinner wall than HDPE pipe for an equivalent pressure rating, which significantly cuts material, drilling and operating costs.”

Thanks to the use of directional drilling, traffic suffered only minor, short-term disruption, and there was no disruption to the railroad, Illinois Highway 154 or businesses in the area. In addition, grading, seeding and roadway repairs were minimized by avoiding open trench installation.

“The rigidity of the Certa-Lok pipe eliminated the need for a casing under the railroad and highway areas,” says Kevin Korte, directional bore superintendent for Korte-Luitjohan Contractors. “We also found it easy to handle and install. It performed very well for us during the installation.”
