Cutting-edge products for tunnel boring

Cutting rings

We develop and produce RingX ® a new generation of TBM disc cutters (cutting rings) with very high performance that improves TBM production and efficiency.

The technical characteristics of our cutting rings guarantee a strong reduction of TBM downtime and consequently a lower number of interventions to the excavation front.

The features of our RingX ® make it extremely performing and cutting-edge in the fields of TBM cutting tools.

Tail brushes

We have designed and manufactured a tail skin brush with an innovative design.

Our BrushX mounted on the TBM shield assures a perfect distribution and sealing of the backfilling mixture with maximum efficiency.

Chemical consumables

A wide range of polymers and ground conditioning agents. Readily biodegradable foaming agents for ground conditioning for EPB TBMs and dedusting and rock drilling improvement.

TBM main bearing grease and tail skin grease.

Mono-and two-components foams and resins, expanding or rigid.

Grout and bentonite

Design of backfilling mixture formulation (bentonite-retardant-silicate basis) for mechanized excavation applications to suit project requirements.

Ground conditioning for Slurry TBMs and cake formation ahead of excavation front inspection.
