It demonstrates high cost performance as an injection material for various auxiliary construction methods!
In recent years, tunnel construction sites have been required to respond to strict conditions, such as construction in urban areas and low cover depths. Under such conditions, the "injection-type pre-support method" has been widely adopted as a safe, reliable, and cost-effective auxiliary construction method. Among the injection materials used in the injection-type pre-support method, silica resin-based injection materials are utilized as they meet many of the demands required on-site, including strength, permeability, safety, and even economic efficiency. 【Features】 ○ Compatible with various geological conditions and construction methods ○ Can efficiently improve the ground For more details, please contact us or download the catalog.
