For downtown job-sites or for restricted areas where the available space becomes the critical element for the job-site set-up, METAX has designed and manufactured a compact jet grouting plant where inside a single container (22’ or 31’ long) are located an high pressure triplex pump as well as a mixing plant (mix capacity 12-24 m3/h)

For small and special job-sites, METAX produces compact jet mixing & injection plants where the mixing unit is also equipped with grout pumps (double effect piston or screw pumps). These plants can be driven by electric or diesel motors with installed emission control devices following the environmental rules of the Client’s Country.

In the field of civil engineering for the construction of tunnels, it is often necessary to carry out both high and low pressure injections to allow the excavation of the tunnels and to complete them in the phases following the ‘mechanised excavation’.

Several techniques are used for this purpose, involving the use of different equipment:
