Benefits & Features
Hydraulic expansion rock bolts are designed based on the principle of expansion through high-pressure water injection into the anchor body. When water is injected into the anchor, the internal expansion element expands and adheres tightly to the borehole wall, forming a stable anchor structure. This accessory is essential for installation and does not require grouting. It is suitable for breaking weak rock formations. It can also be used for temporary support, providing a fast and effective support structure.
