Our services

Pacyfire Engineering LLP provide specialist solutions in Tunnel Fire Protection

At Pacyfire Engineering LLP, our Tunnel Fire Protection services are built on a foundation of engineering knowledge, material science and on-site execution experience. We design and apply cementitious and intumescent passive fire protection systems that protect tunnel structures, services and occupants during severe fire scenarios. Whether the project is a road tunnel, metro tunnel, service gallery or utility corridor, our team ensures that every protected area achieves the specified fire rating with consistent quality, safe execution and full documentation.

Service Satisfaction

At Pacyfire Engineering, Tunnel Fire Protection is a core part of our passive fire portfolio. We support owners, consultants and EPC contractors in selecting, detailing and applying systems that are compatible with tunnel geometry, ventilation concepts, evacuation strategy and project specifications.

Our engineers study fire scenarios, traffic mix, structural design and exposure conditions to define the required fire rating and dry-film thickness (DFT). Based on this, we select globally approved systems – including PACYCRETE cementitious fireproofing and high-performance intumescent coatings – chosen for durability, crack resistance and long-term performance in demanding tunnel environments. From soffits and walls to equipment rooms and escape routes, we help you protect visible and hidden structural elements without compromising functional and architectural requirements.

On site, our trained applicators manage every stage: substrate evaluation, surface preparation, priming, spray/pump application, detailing around services and joints, and sealing with compatible topcoats where required. We use calibrated inspection tools and follow manufacturer data sheets and project QA/QC procedures. Each area is checked for DFT, adhesion and finish so that the installed system matches both the test data and specification.

Whether your project is a new tunnel, a rehabilitation of an existing structure or an upgrade to higher fire ratings, Pacyfire Engineering delivers a complete Tunnel Fire Protection package – from design support to long-term maintenance advice.

Our Services in Tunnel Fire Protection Include

  • Fire strategy & system selection for road, rail, metro and utility tunnels, based on design fire curves, evacuation concept and structural requirements.
  • Design thickness calculation (DFT) and build-up design using tested system data for RABT / hydrocarbon / cellulosic fire exposures, as required by the project.
  • Specification of suitable systems – PACYCRETE cementitious fireproofing, tunnel linings and compatible intumescent coatings for concrete and steel surfaces.
  • Surface preparation & priming of soffits, walls, portal areas and equipment rooms to achieve proper adhesion, cleanliness and coating compatibility.
  • Application of spray-applied linings and coatings by experienced teams using pump/spray or trowel methods, including detailing at corners, kerbs and drainage channels.
  • Fire protection of embedded services such as cable trays, pipe supports, ventilation ducts and penetration zones to maintain continuity of the fire barrier.
  • Detailing of construction joints, movement joints and interfaces with waterproofing systems so that fire protection and tunnel sealing work together.
  • Inspection & quality control – WFT/DFT checks, adhesion tests, pull-off tests where required, rectification of defects and as-built reporting.
  • Repair and maintenance of existing tunnel fire protection, including patch repairs, recoating and upgrading older systems to current performance requirements.
  • Technical liaison & documentation support for consultants, approving authorities, insurers and safety auditors.

With Pacyfire Engineering LLP as your Tunnel Fire Protection partner, you gain fire safety that is engineered, verifiable and built to match the same high standard as the infrastructure it protects.
