Two new POLYVIEWERS shipping out today

Two brand new Polyweld Machinery POLYVIEWER vacuum testing domes are headed out today to our good friends at Jaylon Industries / Jaylon Environmental Systems.

These domes are used in conjunction with vacuum pumps to test weld integrity on HDPE geomembrane liners. By spraying soapy water along the weld seam, and then applying a vacuum, the presence of bubbles can indicate defects in the weld.

Designed by Polyweld Machinery and manufactured locally in Perth, they are an important tool for anyone involved in dam or pond lining. We can supply different options in the vacuum test unit to suit your work environment or testing specifications.
