Made in Japan
Manufacturer: Kyowa Electronic Instruments Co., Ltd.
Model: Water impermeability function diagnosis system
The “Impermeable Function Diagnosis System” is a system to maintain a safe final disposal site by constantly monitoring whether the impermeable sheet is functioning effectively to prevent the outflow of leachate generated in the disposal site into the ground and the inflow into groundwater.
Feature
● Damage can be constantly diagnosed without removing landfill waste ● In the unlikely event of damage, an alarm notifies the abnormality and displays
its position ● Can be used for either single or double water shielding sheet structure ● Identification of more advanced damage location is possible by introducing original numerical simulation analysis (optional)
