Minimum low temperature for dual hot-wedge seaming

June 1st, 2014 / By: / GMA Techline

Does the Geosynthetic Research Institute (GRI) offer any guidance on the minimum allowable ambient temperature to perform double-track fusion welds of HDPE and LLDPE geomembranes?

Reply: We have GRI-GM9 Standard Practice “Cold Weather Seaming of Geomembranes” and it allows for seaming down to -15 C (5 F).
