Urban infrastructure covers core scenarios such as subways and underground utility tunnels, old residential districts and urban renewal, municipal roads and bridges, and sponge city facilities. Faced with multiple challenges including high groundwater level, structural settlement, frequent temperature changes, limited construction space, and strict environmental protection requirements, the product specifically solves various pain points:
Subway and Underground Utility Tunnel Protection: Suitable for scenarios such as subway stations, tunnels and comprehensive utility tunnels (water supply, drainage, and power utility tunnels), it can be directly constructed on wet base surfaces without additional leveling layers, penetrates and fills structural gaps, forms a permanent insoluble crystalline waterproof barrier, effectively blocks groundwater penetration, and ensures the safety of pipelines in the utility tunnels.The product has excellent anti-settlement toughness, can adapt to long-term slight deformation of underground structures, and is convenient for construction. It can be constructed by small mechanical spraying, adapting to the construction in the narrow space of the utility tunnel and greatly improving the operation efficiency.
Old Residential District and Urban Renewal Protection: Aiming at the needs of waterproof renovation of roofs, exterior walls and basements of old residential districts and infrastructure renovation of urban renewal areas, the product has a simple construction process, no need for complex equipment, and can be completed by manual application, with little interference to residents' lives;Its green and odorless characteristics are suitable for residential areas. At the same time, it has good compatibility, can effectively combine with the original waterproof layer and wall base course, solve the problems of uneven base surface and crack leakage of old buildings, extend the service life of buildings, and conform to the principle of "green renovation, convenience and efficiency" for urban renewal.
Municipal Road and Bridge Protection: Suitable for parts such as road base courses, bridge decks, bridge piers and expansion joints, the product has excellent wear resistance and anti-rolling performance, can bear the impact of vehicle traffic and load pressure, and has good impermeability to prevent rainwater from seeping into road base courses and bridge piers, avoiding structural damage caused by frost heave and steel bar corrosion;It has good compatibility with road materials such as asphalt and concrete, and can be used as an anti-seepage base course for road surfaces and bridge decks to improve the durability of municipal roads and bridges.
Sponge City Facility Protection: Suitable for sponge city facilities such as rainwater regulation and storage pools, sunken green spaces, and permeable road base courses, the product has both impermeable and breathable properties, can effectively block the disorderly penetration of rainwater, and does not affect the water storage and filtration functions of the facilities;It has no aging or leakage after long-term immersion in rainwater, can adapt to the working condition of frequent dry-wet alternation of sponge city facilities, and helps cities achieve the rainwater management goals of "infiltration, retention, storage, purification, utilization and drainage".
