Bare Liner – Water Puddle

The ‘Water Puddle Method’ is often the technique of choice for most new bare liner installations. The basic principal of this method uses an induced electric current generated above the bare liner and grounded to the subgrade. A mobile detection device, using an electrical current measurement system, is then deployed across the geomembrane to detect changes in current associated with leaks in the liner.
