Bachy Soletanche keeps sharing with you our latest news. Read More, Know Us More.
On 16 December 2025, we had the pleasure of joining friends and partners at AECOM for a lunch sharing session that sparked meaningful conversations about Hong Kong's geotechnical challenges and solutions.
Our topic:
"Shaft-Grouted Friction Barrettes in Hong Kong: Expertise from Bachy Soletanche Group Limited (BSGL)"
Hong Kong's ground conditions are never simple—deep weathering, karst features, unpredictable rockhead. But that's where BSGL thrives upon: turning complexity into opportunity.
What we shared:
🌟 How our diaphragm wall (D-wall) operations and patented Gripper system are shaping the future of hydrofraise technology in hard rock.
🌟 Why shaft-grouted friction barrettes are a smart, reliable alternative to end-bearing piles for high-rise foundations. We walked through design procedures, construction processes like tube-à-manchette grouting, and how this method delivers cost-effectiveness, compliance, and versatility for reclamation and karst sites.
A big thank you to our speakers Chris Tang and Alex Chan for sharing their decades of experience and insights that make BSGL a trusted leader in ground engineering.
We truly appreciate AECOM for hosting and everyone who joined us to make this discussion so engaging and insightful! It's always inspiring to share knowledge and explore new ways to build smarter, stronger foundations for Hong Kong's future.
