● Injection works



Omega Bolt



- Immediate full load bearing capacity over the entire installed bolt length

- Low sensitivity against vibrations caused by blasting works

- Safe and easy installation

​



CT-Bolt combination Rock bolt



- Efficient, practically proven, and reliable rock reinforcement system

- Combination of an immediate mechanical point anchorage and a fully grouted rock bolt

- Fast installation and flexible post-grouting behind the working face



AT pipe Umbrella System



- Installation with conventional drill jumbos

- Fast self-drilling installation

- Length of pipe umbrella pipes can be adapted to constricted space



Friction Stabilizers



- Easy and fast installation procedure

- Both hand-held and fully automated installation are possible

- Low sensitivity to rock mass displacements



DYWI Drill Hollow Bar System



- Fast and safe self-drilling installation

- Easy and similar operating principle using on-site personnel and standard drilling machinery

- Drilling, installation, and optional grouting in a single operational step



DYWI Drill S-D Expansion Bolt Type T



- Installation using standard drilling machinery

- Simultaneous drilling and installation

- Reduction of cycle time due to the de-coupling of the grouting procedure from installation



Injection Chemicals



- Water Sealing

- stabilizing Fractured Rock

- Void/Cavity Filling

- Bonding

- Bolting



Waterproofing System



- Quick and easy to install

- Very easy handling on-site due to light-weight design

- Safe solution for sealing shrinkage cracks and viods in concrete
