Join esteemed barrier systems expert Professor Kerry Rowe later this month for a virtual talk on geomembrane fusion seams.

Hosted by the IGS Technical Committee on Barrier Systems (TC-B), Prof. Rowe will speak on ‘The influence of thickness reduction and squeeze-out on Std-OIT loss and stress crack resistance of HDPE geomembrane fusion seams’.

The talk will explore the difference in seam squeeze-out antioxidant loss (in terms of standard oxidative induction time, Std-OIT loss) and thickness reduction for three different 1.5 mm-thick high density polyethylene (HDPE) geomembranes seamed using a variety of welding parameters and two different wedge welders. The damaging effect that squeeze-out adherence can have on seam stress crack resistance and time to failure will be emphasized.

The webinar runs on August 29 and repeated on August 30. Register as follows:

• August 29, 7am EDT, 11am UTC, 6am CDT, 1pm CEST, 9pm AEST: https://us06web.zoom.us/webinar/register/WN_bKboHSzgTQq1A_njKXeYjg
