FOREPOLING/ TUBE UMBRELLA SYSTEMS/ PIPE ROOFING
Forepoling/Tube Umbrella Systems/Pipe Roofing
For advanced geotechnical drilling, Pole's case advancing systems offer solutions for a variety of construction techniques, including fore poling, well drilling, and anchoring. Pole's drilling system consists of casing tubes which are drilled through the overburden as an umbrella and filled with grouting. The casing system allows easy driving of the casing tubes into the ground with low torque demand. ela offers a wide range of solutions that are designed to perform in weak ground conditions using either top-hammer jumbos or DTH drill rigs. Pole delivers full package of fore poling tools for drilling: pilots, ring bits, tubes, starter casings, drill rods, grouting plugs & shanks. Our systems are applicable for both permanent and temporary casing.
