Geomembranes tested

Our staff has many years of experience testing and designing with geosynthetic materials. We’ve provided these services in support of many construction projects across Australia, including landfill, solid waste treatment, mechanically stabilized earth (MSE) walls, roadways, and lagoons.
We perform conformance and performance testing on many geosynthetics materials including:
• Geomembrane
• Geotextile
• Geosynthetic Clay Liner
• Geonet
• Geogrid
GIS lab offers a full range of geomembrane testing services, including HDPE weld testing. The geomembrane test services we can complete for you are listed in the table below.
