FAQs

• Where can our Hollow Bar System be used?
  Our hollow bar system is being used in the following fields of application:
  * Soil nailing
  * Wall and shaft stabilisations in mining and tunnelling industries
  * Wall anchorage for construction pits, sheet piling and retaining walls
  * Anti-uplift anchors (against flotation of submerged concrete floors in construction pits or tunnel entrances)
  * Micropiles
  * Any client-desired specific application like strutting, jet grouting or other injection techniques
• What are the advantages of a self drilling system?
  The advantages of self drilling systems are:
  * fast and safe installation (single step casing)
  * proven installation process under various and difficult ground and borehole conditions
  * minimum disturbance of ground conditions
  * low settlement characteristics
  * suitable for tension, compression and cyclical loads
  * broad range of load capacity classes available
  * wide range of drill bits available to deal with various different ground conditions
  * installation is done with universal standard drilling equipment
  * suitable for difficult and restricted access situations
  * robust system and suitable for use in civil-engineering applications and maritime conditions
• Is our system sustainable?
  Our self-drilling anchoring systems are suitable both for temporary and for permanent application. The geometry of the “Geotech thread” creates an optimum bond with the cement grout body. This results in a sustainable product protected against corrosion.
