Teranap is not prone to wind lift

Lighter, thinner membranes have a tendency to lift and move around under relatively low wind velocities.

For example, HDPE of 1.0 mm thickness requires a minimum wind velocity of 13.6 km/h to experience uplift.

During installation uplift can cause numerous problems which result in delays and danger to construction crew. After installation, lighter membranes will continually strain to resist uplift over their service life.

This is unlikely to occur with Teranap as it is the thickest and heaviest geomembranes used for civil engineering lining.

Even the thinnest Teranap 331 is twice as heavy as 2.0mm HDPE.
