AVAYO offers a broad range of application solutions for demanding infrastructure projects. Our MEP support systems for TBM and NATM tunnels are designed to handle extreme environmental requirements while ensuring precise, secure mounting to concrete linings[cite: 3].
Concrete Lining Fixation
Our heavy-duty hardware fixation solutions provide secure anchoring directly to the tunnel’s concrete lining for essential services[cite: 3]:
- Jet Fans installation[cite: 3]
- Catenary system fixation[cite: 3]
- Signaling equipment and Signage[cite: 3]
- Walkway and Handrails fixation[cite: 3]
- Rebars anchoring[cite: 3]
