The Grundomat is an earth displacement tool used to achieve
short shots up to 20 metres in length.
The Grundomat is a pneumatic tool which is operated
in conjunction with an air compressor; no drilling fluids are required when using the Grundomat.
Compressed air repeatedly propels the piston against the rear of the chisel head assembly.
This first compresses the pre-tensioned
steel spring which forces the chisel head assembly forward independently of the main
casing to provide a pilot bore. Then, the same continuous force thrusts the main casing
The Grundomat can be used for bores under driveways, in
congested areas and in confined spaces.
