The Tenbusch Insertion Method (TIM) for trenchless pipe replacement allows local contractors to replace ailing underground infrastructure for both municipal and industrial applications. This unique pipe bursting method jacks (pushes) new pipe in place of the existing deteriorated pipe. Unlike other trenchless methods, the TIM system utilizes the column strength of segmented jacking pipe for the newly installed line. The stringent structural requirements of the TIM System ensure a long lived, structurally superior, end product. 972.221.2304,

Nowak 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,
