Bare Liner Surveys

To avoid the logistics of flooding the geomembrane with water, the exposed geomembrane can be tested for leaks using a water puddle test. This test is used on geomembranes that are in direct contact with the supporting sub-grade or a GCL. Procedures for this method are specified in ASTM standard D7002.The bare liner test is to detect electrical current flowing through a hole in the geomembrane liner using a small amount of water that is temporarily placed in contact with the liner using a squeegee.

  The electrical leak location method is a powerful tool used to detect electrical paths through leaks in a geomembrane liner.Electrical measurements are then made on the soil or in the water to locate these points of current flow through the leaks. ASTM D6747 describes the various implementations of the method.Electrical leak location surveys are conducted on the primary or secondary geomembrane liners with water or soil covering the liner.
