• It is much better than the existing grout is the thermal conductivity. The developed materials was examined by applying the grout in the field.
• For the investigation of the hydrogeological characteristics, step-drawdown test, long-term pumping test, and recovery test have been carried out for two developed pumping wells. Step-drawdown test has been performed on 4 step flowrates of 150, 300, 450, 600 m³/day for 1 hour, and long-term pumping test on flowrate of 500 m³/day for 24 hours, and recovery test for 6 hours. Since the underground water filtrated by riverbank is flowing smoothly into the well, the water level goes down slightly for the long-term test.
