Mastering Extrusion Weld Examination: Essential Checks Before, During, and After Welding

(Originally aired 12/18/25 on Zoom)

Don’t Let Hidden Extrusion Weld Failures Sink Your Next Project

Picture it – the North Atlantic Ocean, April 14, 1912. You’re on the maiden voyage of the RMS Titanic and enjoying the good life when suddenly everything turns into complete chaos. You get word that the vessel hit an iceberg, and you have to head for the nearest lifeboat – panic and uncertainty set in. Fast forward 113 years to today.

Fast forward to 2025 – your multimillion-dollar containment project leaks because an extrusion weld failed… and nobody saw it coming. Panic and uncertainly will set in….

Just like that iceberg, 90% of an extrusion weld quality is hidden beneath the surface once it’s complete. One weak weld can trigger catastrophic failure, massive remediation costs, and reputational damage that takes years to recover from. The stakes are high.

On a typical 10-acre geomembrane job you’re looking at 3,000–5,000 linear feet of extrusion welding — that’s thousands of opportunities for invisible defects to hide. Here’s the good news: unlike icebergs, extrusion welds are built step-by-step — and every single step gives you a window to spot trouble BEFORE it becomes a $1,000,000+ nightmare.

In this tactical, no-fluff session you’ll discover:

  • The 7 red flags in seam preparation that predict 95% of all extrusion weld failures (and how to catch them in under 30 seconds)
  • Proven environmental controls that dramatically boost consistency even in wind, cold, or heat
  • Exactly what elite CQA inspectors look for (and flag) on HDPE & LLDPE extrusion seams
  • Bonus: Live photo walkthrough of “good vs. catastrophic” welds pulled straight from the field

This is NOT theory.
These are the exact inspection protocols used by the most respected third-party CQA firms in North America.

Who this is for:

  • Project owners who refuse to write million-dollar checks for containment failures and rework
  • Engineers who want bulletproof specs and CQA plans that maximize client ROI and minimize callback nightmares
  • Liner installers who want zero failed test welds
  • Anyone bidding or managing HDPE/LLDPE geomembrane projects
