On 24 February, the PVC Geomembrane Institute (PGI) will hold a half-day short course titled “Specifying with PVC Geomembranes.” The event is part of the Minnesota Polution Control Agency (MPCA) annual conference. Note: For those who cannot attend the 24 February course, PGI will present “Specifying” again on 2 April with the Montana Department of Transportation.
PVC specification workshop:
The workshop will address the following topics: formulation and manufacturing; fabrication and installation; specification and testing; and PVC geomembrane interface strengths and slope stability. Several case histories will be presented, including one involving a 30-year-old 20-mil PVC geomembrane. Finally, and most importantly, a hands-on demonstration of wedge welding and air channel testing of PVC geomembranes will be conducted.
Attendees will leave with a broad knowledge of what is required to design, specify and construct with this material. The course will include the ASTM testing required for compliance with the new PGI 1103 Specification for PVC geomembranes.
Additional note:
To help ensure only high quality PVC is used in applications, the PGI plans on adding a minimum plasticizer molecular weight spec and a leachate immersion test to the current PGI specification. Both changes are scheduled for 2004.
