Underground engineering construction covers core scenarios such as underground utility tunnels, underground parking garages, underground commercial spaces, tunnels and foundation pits. Faced with multiple challenges including high water level seepage, wet base surfaces, structural settlement and limited construction space, the product provides targeted anti-seepage and protection solutions:
Underground Utility Tunnel Protection: Suitable for parts such as the main structure of the utility tunnel, pipeline interfaces, expansion joints and inspection wells. It can be directly constructed on wet base surfaces without additional drying and leveling, deeply fills gaps and forms a permanent insoluble crystalline waterproof barrier, effectively preventing groundwater from seeping into the interior of the utility tunnel and protecting the safety of pipelines.The product has excellent anti-settlement toughness, can adapt to slight structural deformation during the long-term operation of the utility tunnel, and has strong compatibility with utility tunnel gaskets and anti-corrosion coatings, forming a composite protection system to ensure the long-term operation and maintenance of the utility tunnel.
Underground Parking Garage Protection: Targeting key parts such as the garage floor, side walls, roof and post-cast strips, it can resist the upward seepage of groundwater and rainwater backflow, prevent dampness on the garage floor and leakage on the walls, and avoid ground damage and leakage caused by vehicle passage and parking.The rigid protective layer formed after construction is wear-resistant and anti-rolling, can bear the impact of vehicle loads, and can quickly repair cracks and damages on the base surface, adapting to the needs of large-scale garage construction and later local maintenance.
Underground Commercial Space Protection: Suitable for the waterproofing of the ground, walls and ceiling base course of confined spaces such as underground shopping malls, supermarkets and exhibition halls. The product's green and odorless characteristics will not affect the space use experience, can effectively block groundwater seepage, and prevent wall mold and ground sanding.It has strong compatibility with decoration materials, and can directly connect subsequent processes such as floor tile laying and wall decoration after construction, without affecting the decoration progress and quality of the commercial space.
Tunnel and Foundation Pit Protection: Suitable for parts such as underground tunnels, foundation pit side walls, inverted arches and openings. It can be constructed synchronously with shotcrete as an anti-seepage base course, fills gaps in the base surface and micro-cracks caused by blasting, resists groundwater seepage around the foundation pit, and prevents dampness on the foundation pit side walls and tunnel leakage.The product has excellent impact resistance, can bear the extrusion of backfill soil in the foundation pit and the disturbance of tunnel construction, and is convenient for construction, adapting to the narrow space of tunnels and the operation of complex nodes of foundation pits.
