Finishing Works — Precision Finishing for Transport Infrastructure
Fire protection, acoustics, waterproofing and corrosion protection — plus LED lighting, ventilation, automatic incident detection, telecoms and automation. GTA Group delivers complete Finishing Works for mobility infrastructure, from design to final handover.

Our approach
Fire · smoke protection
Acoustic treatment
Waterproofing · water ingress
Aesthetics · corrosion protection
Electromechanical equipment · automation
GTA Group carries out finishing works for mobility infrastructure — tunnels, underground car parks, civil engineering structures — across two complementary dimensions: technical civil engineering finishes (fire protection, acoustics, waterproofing, corrosion protection) and electromechanical equipment (LED lighting, ventilation, automatic incident detection, telecoms, automation).
Delivered jointly by GTA Infra and GTA Axyscom, with support from our other subsidiaries specialising in fire-resistant and anti-corrosion coatings, this integrated offer covers design, installation and commissioning — with an in-house engineering and design office and teams experienced on more than 50 European tunnels.

What we offer
Our Finishing Works services
From fire protection to long-lasting aesthetics — GTA Group covers all finishing works for mobility infrastructure, from design to final handover.
Fire, gas & smoke protection
Regulatory protection
Passive fire protection is at the heart of GTA’s business — with solutions covering every type of fire (cellulosic, hydrocarbon pool fire / jet fire) and every type of structure.
Passive fire protection to regulatory standards
Acoustic treatment · sound insulation
Comfort · regulatory compliance
Tunnels, civil engineering structures and confined spaces generate specific noise issues. GTA deploys acoustic solutions suited to the technical and aesthetic constraints of each structure.
Acoustic and thermal treatment of spaces
Waterproofing · durable structures
Waterproofing · rehabilitation
Water is the leading cause of deterioration in underground and above-ground infrastructure. GTA waterproofs new structures and rehabilitates existing ones.
Waterproofing and structural strengthening
Long-lasting aesthetics · corrosion protection
Finishing · long-term protection
The finish of a structure determines its durability and its image — GTA delivers both the aesthetic appearance and long-term structural protection, with recognised operator certifications.
Long-term protection through technical finishing
Electromechanical equipment · automation
In partnership with GTA Axyscom
GTA Axyscom leads the electromechanical side of Finishing Works — supply, installation and commissioning of all technical equipment in tunnels and underground structures.

What sets us apart
GTA Group is the only player on the market able to deliver Finishing Works in full — civil engineering and electromechanical equipment coordinated through a single point of contact, from engineering to commissioning.
Where traditional players separate civil works packages from equipment packages, GTA Group brings the two together — GTA Infra for structural finishes (fire, acoustics, waterproofing, corrosion protection) and GTA Axyscom for equipment (LED, ventilation, AID, telecoms, automation). The result: fewer interfaces, greater technical consistency and controlled lead times.
