The TBM Segment Sealing Gasket is a specialised waterproof sealing profile designed for use between precast concrete segments in Tunnel Boring Machine (TBM) tunnel linings. Manufactured from high-performance EPDM or other specified elastomer compounds, these gaskets provide reliable long-term waterproofing in demanding underground environments. Designed to maintain watertightness under groundwater pressure, they help protect tunnel structures from water ingress throughout their service life.

TBM Segment Sealing Gaskets are precision manufactured and tested to withstand repeated opening and closing cycles during segment installation. Corner joints are hot-vulcanised to match the exact geometry of each segment, ensuring consistent sealing performance and reliable waterproofing across the entire tunnel lining system.

Manufactured using high-quality materials and advanced production techniques, these gaskets accommodate normal casting, installation and operational tolerances while maintaining an effective seal. Their resistance to chemical attack, groundwater exposure and biological degradation makes them suitable for long-term use in challenging ground conditions. Profiles can be customised to suit project-specific tunnel geometries, segment designs and performance requirements.
