Grouting anchor bolt Advantage:

1, easy and similar operation principle for different rock mass and soil conditions

2, drilling, anchoring and grouting can be performed in one single operation

3, no pre-drilling of a borehole by using a casing tube and extension rods with subsequent anchor installation necessary

4, minor space requirement for the accomplishment of anchoring

5, optimized machinery and manpower requirements

6, basic dimensioning of the required anchoring forces by choosing the appropriate anchor type
