Geomembrane destructive testing

October 1st, 2022

Figure 1. Site 1 pond replacement For almost 40 years, the generally accepted destructive test rate for geomembrane seaming has been one sample for every 500 feet (152 m) of seam. On large projects this leads to hundreds of holes cut into liners that engineers, manufacturers and installers work very hard to make leak proof. […]

The recent bad weather in the USA (low temperatures, fast-dropping temperatures, and strong winds) provides ideal conditions for rapid crack propagation (RCP), “shattering” in exposed high-density polyethylene (HDPE) geomembranes. It is advised that such exposed HDPE geomembranes be carefully monitored for short slow crack growth (SCG), stress cracks along the edges of extrusion welds especially […]
