IGS-NA-Pond-Liner-circlesThough pond lining applications are common, the proper design and operation of pond lining systems requires great care. A large number of facilities in need of liquid containment are sensitive sites at which pond leakage could result in geotechnical failure of the embankments and subgrade, environmental damage, loss of valuable operational solutions or water, and disruption of operations. In this webinar, Richard Thiel, P.E., will share decades of insight into the proper design and operation of geosynthetic pond lining systems.

The engineering information in the session provides guidance and key considerations for those who work with potable water reservoirs, stormwater detention ponds, mining spoil containment sites, irrigation water storage, wastewater lagoons, food and industrial processing facility wastewater treatment ponds, hydrofracking containment ponds, pumped storage reservoirs, and more.

Attendees will learn about:

  • Geotechnical issues for pond design
  • Liner Configuration and Leakage Management
  • Liner Uplift Considerations
  • Durability and Aging of Exposed Geomembrane
  • Slope Deformation Due to Wave Action
  • Pond Operations

 
Participants will earn 1 PDH at the conclusion of this webinar.

Who Should Attend: Owners and operators of liquid containment facilities; contractors involved in lined pond construction and maintenance; and civil engineers, hydraulic engineers, water engineers, stormwater engineers, wastewater engineers, agricultural engineers, gas and oil extraction engineers; and mining engineers that design containment facilities.

Richard-Thiel-headshot-circlePresenter Bio: Richard Thiel, P.E., has more than 30 years of experience and specialization in containment design applications for geotechnical projects, waste containment, secondary containment of fuel, and leach mining applications. His work has involved extensive interaction with feasibility evaluations, design, permitting, design peer review, economic evaluations, failure analyses, and construction of waste facilities and surface impoundments. He is an expert in the design of liner systems with soils and geosynthetics, leachate management systems including pipelines and pump stations, geotechnical site reconnaissance and resource investigation programs, construction quality assurance (CQA), and assistance in developing state solid waste regulations.

IGS-NA Announces a New Webinar: Understanding the Role of Minimum Average Roll Values (MARV) in Geosynthetic Specifications

wufooform-logo-igs-naIGS North America Presents
WEBINAR: Understanding the Role of Minimum Average Roll Values (MARV) in Geosynthetic Specifications

Understanding minimum average roll value (MARV) is essential in ensuring data support product requirements reported by the manufacturer. There appears to be confusion in the geosynthetic industry concerning the application and definition of product requirements particularly as they relate to MARV. MARV is a statistical value and not a ‘minimum’ number. The interpretation of these values has become an issue and actual data may not support a calculated MARV that meets or exceeds the published MARV.

Attendees will learn about:

  • The statistical approach used to determine MARV
  • Current methods of calculation for MARV as compared to the statistical approach based on process performance
  • Additional guidance including ASTM test methods will be discussed to provide an organized approach to sampling, testing and management of test data and certifications

 
Participants will earn 1 PDH at the conclusion of this webinar.

Presenter Bio: Beth Wilbanks has been with TenCate Geosynthetics for approximately 20 years. During most of that time she led the Quality department and was instrumental in achieving ISO 17025 laboratory and ISO 9001 quality management accreditation. Her current role at TenCate Geosynthetics is Director of Product Management. She is actively involved in ASTM Committee D35 on Geosynthetics and was recently recognized for her efforts in the development of D8102 Practice for Manufacturing Quality Control of Geotextiles. She continues to work in the quality area and has coauthored and presented a paper on the MARV topic and its impact on the geosynthetics industry.
