Pilot-guided auger boring
Pilot-guided auger boring uses advanced technology for precise and controlled underground boring. A pilot pipe is first installed along a predetermined trajectory. It is guided by advanced navigation and control systems. Next, the actual pipe is jacked along the same trajectory, ensuring minimal surface disturbance.
Ideal for urban infrastructure and environmentally sensitive areas, this method offers high precision, increased safety and efficiency, resulting in faster and cost-effective solutions.
Microtunnelling with dry soil transport
Microtunnelling with dry soil transport is an advanced technique for constructing underground tunnels. It uses a tunnel boring machine that mechanically excavates the soil and removes it at the same time. Dry soil transport ensures efficient removal of the soil without the use of water. This method is ideal for urban areas and environmentally sensitive sites, as it allows accurate and safe boring with minimal surface disturbance.
The result is a fast, reliable and cost-effective solution for a variety of underground infrastructure projects.
Open front jacking technique
Open front jacking is a reliable technique for creating underground passages. It involves jacking a pipe with an open front through the ground, while displacing and removing the soil in front of the pipe. This method is ideal for short distances and straightforward soil conditions.
Open front jacking offers an efficient and cost-effective solution, with minimal surface disturbance, making it suitable for various infrastructure projects in both urban and rural areas.
