• Pipe Jacking and Tunneling:  This method installs a carrier pipe directly into the earth. Pipe examples: Reinforced Concrete Pipe (RCP), Fiberglass Reinforced Pipe (FRP), or Steel Casing. The operator works inside the shield at the face. This method can install diameters from Ø42" to Ø96" with drive lengths up to 1000 Lft.



• Tunnel Boring Machine (TBM):  This method is similar to pipe jacking and tunneling, but consists of a powered boring head. The operator is positioned inside the tunneling head. This method can install diameters from Ø42" to Ø114" with drive lengths up to 1200 Lft. Longer drives are feasible with intermediate jacking stations.




• Microtunneling (MTBM): A method of pipe jacking for wet and unstable ground conditions or contaminated soils. Microtunneling is generally defined as remotely controlled pipejacking (personnel-entry is not required) whereby the soils at the cutter face are controlled to maintain balance. Some examples of microtunneling applications are crossings under levees, waterways and sensitive wetlands. The system consists of several pieces of machinery that function together, controlled by an operator who monitors and controls the tunneling operations from a console inside a control container on the surface. and can install diameters from Ø30" to Ø96".

• Guided Boring Machine (GBM): This method installs small diameter pipes with grade and alignment precision. The pipe installation involves a three-step process where launch and reception shafts are strategically located to minimize surface disruption. The process is used in conjunction with a theodolite guidance system to provide accurate pipe installation. installation of pipe in the Ø4" - Ø48" OD range in displaceable soil under 50 blow count.




Lowe Construction provides complete trenchless service beginning with the excavation of the pits (depths exceeding 45 Ft. deep) to the installation of the required carrier pipe.
