This is the subsidence prevention geothermal system and the water distribution pipe is installed in the geothermal boreholes to enable the normal looping of the cyclic water at the time of geothermal boreholes subsidence for the stable geothermal system operation.

There are 3 characteristics of this product,
1) Install the recycling water pipe to prevent geothermal boreholes subsidence.
2) Install the filler in between the inside casing and excavation hole to increase heat conductivity rate
3) Create the geothermal boreholes on the lowest part by securing the grouting zone to have no interval even when the inside casing joint part is deviated.
