This technology is a polyurethane injection method for tunnel backfill repair that takes the environment into consideration and excels in workability. The injection equipment is very compact, and the filling material is transported in a liquid state, occupying about 1/40 to 1/12 of its volume after foaming, allowing all necessary materials to be loaded onto a single 4-ton truck. It can foam and cure even in areas where water has accumulated, making it effective for groundwater stoppage. Additionally, no chlorofluorocarbons, which contribute to ozone layer depletion and global warming, are used in the foaming agent. 【Features】 ■ Excellent workability ■ Lightweight ■ Cost-effective ■ Environmentally friendly ■ Can foam and cure even in areas where water has accumulated, effective for groundwater stoppage *For more details, please refer to the PDF document or feel free to contact us.
