Spring Water Suppression Material (Water-foamed Urethane) 'Stronger'
Foam curing while replacing water! Good reactivity in water allows for filling and sealing of water channels.
"Stronger" is a material that solidifies through a reaction by mixing liquid A and liquid B. When it reacts without contact with water, it forms a high-strength solid without bubbles, and when it reacts with water, it becomes a foamed solid that acts as a groundwater suppression material. The ground improvement using this product is a risk management strategy to prevent various issues caused by geology and groundwater, forming a dewatering zone around the tunnel to mitigate the impact on excavation. It excels in dewatering and ground improvement effects, groundwater resistance, and workability. 【Features】 - The foamed solid has independent bubbles, giving the improved zone high water impermeability. - Before foaming begins, it is in a solution form, allowing penetration into fine cracks. - Strength develops quickly, enabling excavation to start immediately after construction. - Its high viscosity makes it resistant to being washed away by groundwater, providing high groundwater resistance. - By combining high-pressure pressure management, it demonstrates high dewatering effectiveness against high-pressure groundwater. *For more details, please refer to the PDF document or feel free to contact us.*
basic information
【Other Features】 - It replaces water while foaming and curing, allowing for good reactivity underwater and the ability to fill and block water channels. - It penetrates and foams into cracks in rock formations, enhancing the internal stress of the ground and strengthening the bonding force between rock fragments. - With a fast rise time, it has low runaway properties, enabling localized improvements around bolts and steel pipes. - Compared to cement-based or water glass-based injection materials, it excels in the adhesive strength that bonds rock fragments together. - It can be applied by tunnel workers, and the required equipment is relatively simple. - It can be applied while excavation is ongoing, leading to a reduction in construction time compared to conventional chemical injection work. *For more details, please refer to the PDF document or feel free to contact us.*
