Vertical Expansion of Landfills with Geosynthetics
📅 Wednesday, 14 October 2026
🕚 11:00 AM Brisbane time
⏱️ 1-hour live webinar
What happens when a landfill needs more capacity, but expanding its footprint is constrained?
Join us for ACIGS Webinar Series #54: Vertical Expansion of Landfills with Geosynthetics, where our presenters will explore how geosynthetics can contribute to practical engineering solutions for the vertical expansion of existing landfill facilities.
The webinar will bring together international and Australian experience, moving from the background and development of the approach through to real-world case studies and considerations for assessing the feasibility of vertical landfill expansion.
Our Presenters
Simonne Eldridge | Tonkin + Taylor
Simonne will introduce the background and history of vertical landfill expansion and discuss how the approach can provide a practical solution, including a case study from Hong Kong.
Gary Schmertmann | WSP
Amir Shahkolahi | Global Synthetics
Gary and Amir will present a recent Sydney case study, followed by additional observations and lessons from feasibility studies undertaken for other projects.
Moderator
Siamak Paulson | Sigma + Greentec
