About us
Exceptional tunnel construction equipment
AB Tunnelling is an Italian company engaged in the research, design, production, assistance and marketing of two categories of top quality tunnel construction equipment: 1 – Tunnelling – Tools and auxiliary products for tunnel drilling by TBMs (Tunnel Boring Machines), and 2 – Precasting – Prefabricated tunnel lining solutions.
The first category includes: cutting rings for the head of the boring machines (RingX ®); “tail brushes”, which, mounted on the TBMs, ensure distribution and sealing of the backfilling mixture used for tunnelling (BrushX); chemical consumables, a wide range of sealants, resins and soil conditioning agents that facilitate drilling; grout and bentonite, the best raw materials for backfilling mixtures necessary for tunnelling procedures.
The second category comprises: segment moulds (stationary and carousel) for tunnel lining; sealing gaskets and accessories; fibers for concrete reinforcement; GFRP (Glass Fiber Reinforced Polymer) solutions; robotic welding plant and automation; concrete release agent.
RingX ® and BrushX are designed, manufactured and refined in close collaboration with our suppliers, and the rest of the tunnel construction equipment we distribute is manufactured directly by our partners.
From the design stage of a tunnel project, we work with engineers and contractors, analyzing technical solutions and studying the interaction between various tunnel construction components. In subsequent phases, we develop optimization strategies to improve the production and installation of tunnel lining segments, ensuring the highest standards of efficiency and durability.
At AB Tunnelling, we stand alongside industry leaders, providing innovative solutions for tunnel boring equipment, TBM spare parts and high-performance construction materials. Our commitment to quality and innovation makes us a trusted partner in the tunneling industry.

Tunneling Tools: premium-quality TBM cutters and consumables
For the TBMs we provide highly customized tunnel excavation equipment with the sole objective of maximizing productivity. As first-use tools but, of course, also as TBM spare parts, we provide highly customized products with the sole aim 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 ® a premium 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.
To further enhance tunnel excavation efficiency, we provide a comprehensive range of chemical consumables, including sealants, resins, and soil conditioning agents, essential for optimizing excavation processes and ensuring ground stability.
Additionally, our grouting and bentonite solutions include the supply of high-quality raw materials and the formulation of tailored backfilling mixtures, designed to meet the specific needs of tunneling operations, ensuring both structural integrity and long-term durability.

Precast lining solutions: From moulds to segments
In the field of tunnel construction equipment, we supply moulds and handling equipment, plastic fittings, connection systems, waterproofing seals, metal and synthetic fibres and robotic welding systems. During the preliminary phase, we work closely with designers, offering advice to analyse technical solutions and study the interaction between the various components of the segments. In subsequent steps, we propose solutions to optimize and improve the production efficiency and installation of segments by providing durable tunnel coatings.
Through our partnership with Korea Mould, a world leader in the design and manufacture of tunnel segment moulds and handling equipment for prefabricated structures, we have successfully completed numerous international projects. Our services also include the inspection and renovation of existing formwork. AB Tunnelling’s dedicated support in prefabricated structures and consulting services significantly improves the production, handling, storage and plant design of the segments, specifically designed for the Italian and European markets.
Our gaskets and accessories include EPDM gaskets, mechanical connectors, cutting bicones, bolts, washers, bolt bushes, guide bars, load distribution bearings, hard fiber panels, injection and lifting bushes, service bushes and foam strips.
We also offer reinforced concrete fibers, including high-performance steel and macrosynthetic fibers, along with innovative glass fiber reinforced polymer (GFRP) solutions.
