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... »

Diverting Surface Water from Contaminated Spoils at a Former Mine

In June 2017, Concrete Canvas® Geosynthetic Cementitious Composite Mat (CC GCCM) was used to line a series of drainage channels at a remediated mining site in Wicklow, Ireland. The channels were engineered to divert surface water around the former contaminated spoils zones. The site had an extraordinarily long history of mining, with copper mining activities having been reported as far back as 172... »
