GSI offers webinar on expanding landfills

News | April 4, 2017 | By:

The Geosynthetic Institute (GSI) will offer a webinar on “Lateral and Vertical Expansions Over Old and Existing Landfills,” on April 12, 2017, from 11:30 a.m. to 1 p.m. EDT.

With literally thousands of old landfills scattered worldwide, their upgrading (via lateral and vertical expansions) to an engineered landfill is a widespread need. A key aspect for old landfills is to provide proper liner systems, or, namely, geosynthetics. This webinar delves into lateral and vertical expansions. In lateral expansions, orientation, cross-sections, foundation settlement, liner-system behavior, geosynthetic selection, and design details (including translational stability) are explained. In vertical expansions, general conditions, cross-sections, estimating total settlement, estimating and designing against differential settlement, and design details (including accelerated decomposition of the waste) are explained. The webinar will also cover post-closure landfill uses.

Webinars cost $200.00 for GSI members and $250.00 for nonmembers. Successful completion of a multiple-choice test after the webinar carries 1.5 professional development units.
