Maximizing Electrical Leak Location Effectiveness with Covered Geomembranes

By Abigail Gilson-Beck and Julio Ferreira – Designers of geomembrane-lined containment facilities commonly assume two to five leaks per hectare, with each leak of the size or diameter of a few millimeters. A leak is any damage that fully penetrates a geomembrane panel or seam (e.g. hole, perforation, tear, crack or puncture). Typical leaks caused by equipment placing cover material can be orders o... »
