"AGSR-FI" is a polyurethane foam that cures rapidly through the mixing of polyols and modified isocyanates. It reaches its final strength in a short time, allowing immediate use of the tunnel after construction, and it can cure even underwater, making it usable in water inflow environments. By utilizing it as a filling material for back cavities in existing tunnels, it contributes to the restoration of the structural functions inherent to the tunnel and extends the lifespan of existing tunnels. 【Features】 - It reaches its final strength quickly, enabling immediate use of the tunnel after construction. - It can cure underwater, making it usable in water inflow environments. - The foam has independent bubbles, so high water-stopping performance is expected after curing. - Its low foam density means that the load on the lining concrete is minimized. - It complies with the "Guidelines for Safety Management of Polyurethane Injection Materials in Mountain Tunnel Construction." *For more details, please refer to the PDF document or feel free to contact us.
