Geomembranes have been used in North America to contain water in transport canals since the early 1950's. Initially 10 mil PVC was used for all of the early projects but was later replaced by 20 mil PVC and other cost effective geomembranes.
Geomembranes are provided in large factory fabricated panels to reduce field seaming requirements.
Geomembranes provide long term service life as a containment membrane.
Geomembranes are a very cost effective material in regards to overall material cost - resin, sheet, fabricated panel and installation.
The U.S. Bureau of Reclamation (under the Department of the Interior) and the Province of Alberta have both successfully installed millions of square feet of Geomembrane [PVC] in their canal systems.
Leakage loss of this water has been eliminated through the use of Geomembrane linings allowing water to be transported to population areas that do not have adequate water sources of their own. If you live in these areas, Geomembrane has been a critical factor in your lifestyle.
