Drill bit adapters increase flexibility by allowing the use of drill bits designed for other dimensions of hollow bars.
Spacers are used to centre the hollow bars within the borehole and to ensure the correct grout cover of the load-bearing element according to the relevant standards and as specified in the approvals.
The grout swivels consist of a grout body and a swivel shaft and are attached to the shank adapter. A large variety of grout swivels for all standard types of shank adapters is available. The grout swivels are suitable for simultaneous drilling and grouting.
Coupling boxes (crossover couplers) must be installed between the shank adapter and the hollow bar during the drilling operation.
A CE-approved pull tester is available to test the self-drilling nails and piles after installation of the system and curing of the grout body.
We recommend the use of the M400NT grout pump to produce a grout mixture with a controlled water/cement ratio.
For geotechnical applications, we recommend M440GE pump to produce a grout mixture with a controlled water/cement ratio.
