Geosynthetics manufacturer Solmax has launched a Leak Location Suite (LLS) that raises the bar on electric liner integrity (ELI) surveys. Solmax’s LLS aims to raise standards with its advanced approach, building repeatable liner testing and remediation into containment design.
“Geosynthetics are critical to contain waste—they line the world’s biggest landfills and keep hazardous outputs from mines and industrial processes from contaminating the environment,” says Jimmy Youngblood, global geosynthetics manager with Solmax. “But even the best liners can puncture. This can put a company’s investment, reputation and the environment at risk.”
Solmax’s Leak Location Suite comprises a customizable conductive liner, patented Iso-wedge installation tool and spark tester. The value lies in the conductive bottom surface of the liner. It enables ELI testing of covered or exposed geomembranes without the addition of a physical conductive layer—i.e., flooding the substrate or hydrating the subgrade, which can be costly, logistically difficult, and may require subsequent removal and containment of the water waste.
The Solmax Leak Location Conductive Liner can be tailored to the needs of the application, because it comprises a coextruded high-density polyethylene (HDPE) or linear low-density polyethylene (LLDPE) geomembrane. The bottom layer is made of electrically conductive carbon black, but the top layer can be smooth or textured, white, black or green.
The Iso-wedge is designed to ensure that conductive geomembranes are effectively welded together and that the exposed upper seam flap is reliably isolated from the bottom panel.
The S-100 Spark Tester is designed to enable fast, accurate ELI surveys (Spark Tests) on exposed conductive membranes—even on the most challenging surfaces.
