Home About Us Boring Tunneling HDD Communications Shaft Construction Safety Consulting Contact Us Pilot Tube Microtunneling (PTM) Pilot tube microtunneling is a hybrid of three trenchless techniques. It uses a guidance system with the accuracy of a microtunnel machine, a slanted or angled steering head similar to a directional drill and an auger similar to an auger bore machine. This process is initiated with the installation of the pilot tubes along the desired line and grade. These tubes are then pushed or cycled out of the bore hole into the exit shaft by a reaming head. The product pipe is installed directly behind the reaming head and used to thrust the reaming head forward. We’re here to help!

Home About Us Boring Tunneling HDD Communications Shaft Construction Safety Consulting Contact Us Horizontal Directional Drilling (HDD) Horizontal Directional Drilling is a steerable, trenchless method of installing wet and dry utilities below grade. It is suitable for a variety of soil conditions. The borehole diameter and crossing length are inversely proportional with the possible diameters ranging from 1” to 54” and possible lengths from 100’ to 3,000’. Typical HDD pipe products include RJ PVC, FPVC, HDPE, Steel and Ductile Iron. We’re here to help! Let us know if you have questions or would like more information about our services.
