The SupAnchor Self-Drilling Anchor

is a unique anchoring system and is todayÂë

answer to the increasing demands of the

tunnelling industry and ground engineering for safer and faster production.

The system provides advantages for all areas of its

applications, where boreholes would require the

time consuming drilling with casing systems in

unconsolidated or cohesive soil.

Features and Advantages

Fits SupAnchor standard Boomer, ROC and

Mustang rigs.

Particulary suitable for difficult ground conditions.

A high rate of installation since drilling, placing

and grouting can be performed in one single

operation.

Self drilling system eliminates the requirement

for a cased borehole.

Installation with simultaneous drilling and

grouting possible.

Easy installation in all directions, also upwards.

Suitable for working in limited space, height and

in areas of difficult access.

Simple post grouting system. Hot-dipped galvanizing for corrosion protection

Applications

Tunnelling Ground engineering

Radial bolting Slope stabilization

Forepoling Micro injection pile

Face stabilization Temporary support anchor

Portal preparation Soil nailing
