WILLBOLT^® FAST – grouting solutions for demanding anchor fastenings.

At a tunnel construction site, we provided support in anchoring a large rock cavern structure with three interfaces.

The geological conditions (shale sandstone, sandstone shale layers, coal seams) were challenging, and nearby structures required precise and reliable reinforcement. In this case, injection drilling anchors were grouted with WILLBOLT^® FAST.

Why WILLBOLT^® FAST? 
• High adhesion, even in dry and wet conditions 
• Non-flammable 
• Specially developed for anchor bolts and consolidation 

Reliably supporting our partners even in demanding construction projects:
With our versatile product range, we always find the right solution – customized, practical, and efficient.
