From the Field

Practical Tips and Insights from Geosynthetics Installation Professionals.

Geomembrane Panel Deployment

Deploying geomembrane panels requires strict adherence to standardized procedures to prevent punctures, overstressing of the material, and injury to field personnel. Success depends on careful handling, controlled pulling, appropriate gripping tools, and close monitoring of environmental conditions. Use enough installation personnel, spaced evenly along the panel, to avoid strain and fall injuries. Deploy only as many panels as can be properly anchored and seamed within the same working period.

Keeping Geomembrane Welding Equipment Working in the Field

An effective maintenance program addresses the heating system, drive and pressure components, airflow passages, sensors, and electrical connections. Regular cleaning, inspection, functional checks, and trial welds help the equipment maintain stable temperature, speed, and pressure the key variables in producing consistent seams.

Installer Tip: Importance of Clean Overlaps for Reliable Wedge Seams

Before thermal hot wedge welding, ensure the entire overlap area is clean, dry, and free of soil, dust, oil, and other contaminants. Inspect and prepare both mating surfaces: the underside of the upper sheet and the top surface of the lower sheet. Proper preparation supports consistent heat transfer, pressure, and sheet contact, helping produce a uniform seam that meets project requirements. Seam failures including destructive testing failures is often the result of improper cleaning of the liner during welding.

Safe Deployment of Geosynthetics Rolls

Deploying geosynthetic rolls is a routine operation on many containment projects, but it can involve significant hazards. Large rolls of geomembrane, geotextile, geosynthetic clay liner (GCL), and other geosynthetic materials are heavy, difficult to control, and can move unexpectedly when handled or exposed to wind. Safe deployment requires planning, properly selected equipment, clear communication, and awareness of the line of fire.
