For the gas sealing grouting project after the serious Shilin gas disaster, the company introduced special engineering materials. This gas-seal grouting completely stopped the continuous gas escape throughout the tunnel.
A durable grouting material was introduced in 2012, in response to the Taipei MRT tender 640 design. This was a durable grouting material introduced from Japan.
High permeability grouting material was introduced in 2009. This introduced an ultra-low viscosity nano-grade grouting material, which can attain deep penetration of cement and silica gel particles into silty soil. This breaks through the limitations of traditional grout material.
Introduction of subsidence repair precision grout injection method from Finland (Uretek Method).
Hot bitumen water-stop grouting technology was introduced from Canada by our company in 2003, for the hot bitumen grouting method used to accomplish repair of the East Railway New Yongchun Tunnel flood disaster (water pressure 40Bar, flow 80 tones / min).
In 2000, rock plate gas seal method was used for the Taipower Shilin waterway tunnel rock plate gas escape explosion handling project. The company introduced polyurethane resin gas seal grouting method from Germany, and very successfully completed the project.
Introduction of innovative underground structural water leakage repair technology in 1992 – a leak-stop grout method introduced from Germany. This method was applied to the Taipei East-West underground railway tunnel project, and was the founding of the current “High Pressure Water-Stop Grouting”.
