Membrane installation
Coordinate installation areas, membrane layout, overlaps and the working sequence.
Specialist infrastructure
Tunnel waterproofing
Specialist membrane work needs an agreed installation sequence, careful detailing and documented seam inspection.
Start with the application.
For the white-and-orange two-colour PVC system illustrated here, the white surface is visible after installation and the orange reverse is visible at rolled or folded edges. The required membrane, support, protection and test methods must follow the project specification.
What the work can involve
Seam welding
Define welding parameters and inspection or testing requirements for the specified membrane.
Interfaces & details
Review terminations, joints, penetrations and transitions against the drawings.
Quality records
Agree the inspection plan, records, responsibilities and acceptance criteria before work.
What to share with us
Approved drawings and specification; membrane type and thickness; installation area; tunnel access and work-front schedule; testing and documentation requirements.
Scope, material requirements, preparation, testing, protection, access and any warranty are agreed in the written proposal.
