Silica resin injection material "AGSR"
Polyurethane injection material for tunnel auxiliary construction methods! It excels in ground improvement effects.
"AGSR" is a ground consolidation material made from rapidly foaming modified polyurethane by mixing special sodium silicate and modified polyisocyanate. It is an injection material with excellent economic efficiency and flame resistance, with numerous achievements in a wide range of geological conditions, and it complies with the "Guidelines for Polyurethane Injection in Mountain Tunnel Construction" issued in February 2020. Since it can foam and provide localized improvement within the ground, the injection volume is small, making the total cost comparable to that of cement injection materials. 【Features】 ■ Excellent permeability, allowing for localized improvement around bolts and steel pipes ■ Rapid strength development, resulting in the formation of high-strength consolidated bodies ■ Greater adhesive strength for consolidating rock masses compared to cement-based injection materials ■ Easily accommodates leaks from the ground with interval injections ■ Short rise time allows for consolidation even in the presence of groundwater, minimizing impact on the surrounding environment *For more details, please refer to the PDF document or feel free to contact us.
