We enhance and facilitate tunnel construction with exceptional products

AB Tunneling is an italian company engaged in the research, design, production, assistance and marketing of products and equipment for tunnel construction using mechanical cutters (TBM s, Tunnel Boring Machines).

For the mechanical cutter we provide highly customized products with the sole objective of maximizing productivity. Our flagship, the RingX ® cutting ring, has been designed and manufactured with one purpose: to achieve extremely high levels of performance. The uniqueness of RingX ® is certified and attested by both Italian and European patents. This makes RingX ® the only product on the market today capable of meeting all the production and economic needs of the construction site.

Our brushes, BrushX, coupled with the tail sealant, form a sealing system that ensures perfect confinement of the two-component annular gap filling mixture. BrushX are produced with the highest quality harmonic steel and designed to guarantee the perfect balance between durability and performance.

In the field of segment prefabrication, we supply formwork and equipment for their handling as well as plastic accessories, connection systems, waterproofing gaskets, and metal/synthetic fibres, along with robotic welding systems.

We offer a range of more than 15 resins of various chemical compostions, including structural, rigid, semi-rigid and expanding types which are used to stabilize and consolidate fault zones at the excavation face or behind the prefabricated segments.

In the preliminary phase, we collaborate with designers as consultants, to analyze technical solutions and study the interaction between the various elements that make up the prefabricated segment. In the subsequent phases we develop proposals to optimize and enhance the efficiency of the production and installation of the segments, which constitute the definitive lining of the tunnel.
