METHODS OF MAKING GROUND CONTAINMENT LINERS

摘要

The present invention provides methods of making containment liners to protect the environment from spills and leaks at oil and/or gas production sites and other sites. The containment liners comprise a first felt geotextile layer and a polymeric barrier layer embedded partially into the felt geotextile layer.

主权项

1. A method of making a containment liner comprising:
providing at least one felt geotextile layer; and extruding a molten polymeric barrier layer material adjacent to the at least one felt geotextile layer and applying pressure between the molten polymeric barrier layer material and the at least one felt geotextile layer to thereby embed at least a portion of the polymeric barrier layer material into the at least one felt geotextile layer.
