Hollow-Bar Micropiles

Simultaneous drilling and grouting for restricted-access foundations.

Hollow-bar micropiles combine drilling and grouting in one operation, enabling fast installation and reliable load transfer in challenging ground. Their compact installation equipment makes them well suited to restricted-access and low-headroom sites.

• High compression and tension capacity
• Suitable for variable ground
• Compact drilling equipment
• Low noise and vibration
• Minimal disturbance to structures
• Flexible lengths using couplers
• Fast simultaneous drill-and-grout process
• Good performance in restricted access
