Register For Limiting Geomembranes Strains Webinar

Examine factors affecting strain limits in geomembranes at a webinar this month.

Professor Richard Brachman, of Queens University, Canada, will be exploring ‘Calculating and limiting geomembrane strain’ in his talk, which will discuss this issue in relation to various applications including bottom liner, cover, or cap, and pond applications.

Additionally, Prof. Brachman will share recent advances in calculating strain and discuss the limitations of past simplifying assumptions. He will also assess the long-term effectiveness of protection layers to limit strain from overlying materials in bottom application geomembrane liners.

Multi-award-winning practitioner Prof. Brachman has unique expertise on measuring the physical response of geosynthetic liners and buried polymer structures using innovative large-scale experiments, field studies and numerical analysis. He has made significant contributions on the assessment of service life and long-term strains in geomembranes, as well as geosynthetic clay liner hydration and dimensional stability, and the field performance of exposed composite liners.

The webinar will run on June 28 and repeated on June 29. Register as follows:
