Tunnel Lining and Waterproofing:
Used for injecting grout into the gaps between tunnel segments to ensure a watertight seal and structural integrity.
The high flowability of colloidal grout allows it to penetrate fine cracks and voids, providing effective waterproofing and reinforcement.
Slab Track Bed Stabilization:
Injects grout beneath railway sleepers or track slabs to fill voids, correct settlement, and improve load distribution, enhancing track stability and passenger comfort.
The precise control over the W/C ratio ensures minimal shrinkage and high early strength development.
Void Filling and Ground Improvement:
Fills voids beneath railway embankments, bridges, or culverts to prevent settlement and maintain track alignment.
Used for soil stabilization and liquefaction mitigation in earthquake-prone areas.
Anchoring and Rock Bolting:
Injects grout into boreholes to anchor rock bolts or soil nails, providing additional support to unstable slopes or tunnel walls.
