Innovation is in our DNA
Soletanche Bachy has been responsible for numerous disruptive innovations in soil technologies and foundations. And thanks to our equipment, materials methods and research experts, we are continually improving our processes, our machines and our materials to meet your new challenges and anticipate those of tomorrow.

Hydrofraise®
In the 1970s, Soletanche Bachy developed the Hydrofraise®, a benchmark machine for boring diaphragm walls.
We have been constantly developing it since its creation. It is now available in several versions:
- Compact for work with limited headroom,
- Containerisable to reduce shipping time and carbon footprint
- With a gripper for very hard ground,
- Equipped with an electric power pack, or even all of these at the same time
How does Gripper work?
The Gripper system, developed by Soletanche Bachy, enables the drilling of deeper diaphragm walls into extremely hard rock formations (with resistance exceeding 100MPa). With this innovation, Bachy Soletanche Singapore can excavate hard soil and rock, providing a competitive advantage in the Singapore infrastructure market for diaphragm walls.
The Hydrofraise® with Gripper applies a thrust on the drilling tool that can be superior to its own weight, pushing the limits of drilling, thanks to its two modules:
Our Hydrofraise® in Singapore
Hydrofraise® HF8
Solution for deep excavation in very hard rock. Equipped with grippers, the effective pushing force on the drilling tool can reach 200 tonnes. With the pulldown mechanism, special cutting head with roller bits can be used, enabling the HF8 to tackle the challenge of excavating into the hardest rocks, such as granite.
