New Practice for Thermal fusion Welding of Geomembranes

1. Scope

Provide general guidance on how to assemble polymeric geomembranes: influence of temperature, speed and pressure, preparation / cleaning of the surface, etc.


dual-track fusion; seam, HDPE; LLDPE; PVC; fPP


The proposed practice may be used in conjunction with other standards to help in obtaining the best performance from geomembrane liners. It will be useful for engineers willing to specify consensual, best practices for seaming geomembranes.

The title and scope are in draft form and are under development within this ASTM Committee.
