Rehab Spotlight: Trenchless Pipe Replacement

Trenchless pipe replacement methods as available from TT Technologies, TRIC Tools, Ditch Witch, Tenbusch and Nowak Pipe Reaming.

TT Technologies
Static System

Burst and replace water, sewer, gas and other pipes with the Grundoburst static pipe bursting system. The Grundoburst can pull in a variety of replacement pipe including PVC, DIP, ABS, cast iron, fusion welded HDPE and VCP jacking pipe. Pulled by a hydraulic bursting unit, the cutter head’s special cutting wheels split the host pipe. Six models are available for bursting 2 to 54-inch pipes and larger. 800.533.2078,

TRIC Tools
The X30 is a versatile choice for both residential and commercial pipe bursting projects. The X30 puller weighs only 75 pounds and is capable of replacing from ¾-inch water lines to 6-inch sewer laterals. Paired with TRIC’s newly released compact 18-hp hydraulic pump, the X30 can replace 100 feet of 6-inch pipe in less than 20 minutes. Add TRIC Tools’ Unified Force pneumatic-assist head and burst 8-inch pipe with confidence. 888.883.8742,

Ditch Witch
Static System

With the PR100 pipe bursting system—which includes the hydraulic bursting unit, job box and power pack—you get 100 percent Ditch Witch design, engineering and manufacturing working together for optimal performance. Stoutly built with heavy-duty, commercial-grade steel and engineered with 100 tons of pullback force, the PR100 is capable of bursting steel pipe and bursting ductile iron, clay, PVC and cast iron pipe up to 16 inches in diameter. A fully enclosed yet fully accessible power pack is the quietest in its class (83 dBA); features to enhance productivity include remote drains and an auxiliary pump for running hydraulic power tools. With a rod box that mounts on the bursting unit, the PR100’s compact size leaves a small footprint, which means less disruption and less potential interference with adjacent structures. 800.654.6481,

Push Technology

Tenbusch manufactures a line of trenchless equipment that allows the local contractor or city crew to replace or upsize existing old pipe (water or sewer). The Tenbusch Insertion Method (TIM) system utilizes several rigid pipe materials including – clay, ductile iron, polycrete, Hobas pipe, steel and stainless steel. The equipment is all hydraulic and uses no percussion. This patented trenchless process requires small entrance/exit pits. Tenbusch manufactures a number of different jacking units to accommodate a range of piping materials and sizes as well as specific job site conditions (including a jacking unit that works from within a standard manhole). The equipment comes as a complete package, including hydraulic power units using environmentally safe hydraulic oil and lubricant systems that are matched to the jacking units. 972.221.2304,

Nowak Pipe Reaming
Pipe Reaming

The InneReam system places no undue stress on nearby fragile structures or paving during the installation process, consequently it also reduces stress on the installer. The system provides for the removal of existing VCP, PVC, AC, reinforced (Class II and III) or non reinforced concrete pipe, and the simultaneous replacement with an HDPE , PVC or restrained joint ductile iron pipe of equal or larger diameter, double diameter replacement being the practical maximum upsize. Removal of the in-place pipe is accomplished by back reaming using a directional drilling machine with a cutter head that reduces the existing pipe to small pieces which are carried along with other excess particles by the drilling fluid to an extraction point. 316.794.8898,
