The raise boring method is a precise and efficient technique for constructing shafts in tunneling projects. This method involves drilling a pilot tunnel downward from the surface to the desired depth. Once the pilot hole reaches the target location, a reaming head is attached, and the hole is enlarged as it is pulled back upward, creating a smooth, circular shaft. This technique is highly effective for creating vertical and inclined shafts with minimal disruption and increased safety compared to

The Pilot Tube Method (PTM) delivers precision and versatility for underground construction! Guided pilot tubes are installed first, achieving ±1 inch grade and ±3 inches alignment accuracy, then upsized to place the final pipe. PTM combines elements of microtunneling, auger boring, pipe jacking, and horizontal directional drilling, making it adaptable to a variety of soils and projects. Explore how top contractors worldwide use guided boring technology to tackle even the toughest challenges: ht
