Erosion Control with Geosynthetics

Erosion is a natural process, resulting from the interaction between water and soil. Unfortunately, this can cause severe damage to infrastructure and endanger people’s lives. Culverts, roads, bridge foundations, embankments, landfill slopes, MSE walls, and other critical pieces of infrastructure are susceptible. With greater urbanization occurring around the world and population centers swelling along coastlines and rivers, the collective need to better manage erosion threats has intensified.

Geosynthetics provide highly engineered solutions for solving all of these erosion problems.

The Dipole Method (ASTM D7007): Advantages, Technique, and Necessary Site Conditions

Among the various types of electrical leak location methodologies used to evaluate geosynthetic lining systems in the field, the dipole method has a unique distinction: it is the only ASTM standardized ELL practice that can locate damage to geomembranes caused during or after cover material placement. Dipole technology can locate very small damage points, such as pinholes or knife slices, under several feet of earthen material. It can even be applied to filled impoundments that are actively in service. As such, dipole surveys are a powerful tool for lined facility validation and protection; but, like any ELL methodology, it can be rendered ineffective if site boundary conditions are poor. In this webinar, Abigail Gilson-Beck, one of the leading experts on ELL, explains ASTM D7007 standardized procedures, including leak detection distance testing and the various methods of data analysis. The importance of good site boundary conditions is detailed with case studies. Earn 1 PDH at the conclusion of the first webinar.

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.

Overview of Electrical Leak Location (ELL) Methods and Their Application

All geomembrane-lined containment facilities should be tested for leaks before going into service. Early detection of leaks allows for swift and effective repair pre-service, protecting the engineer, contractor, owner and in many cases the environment. There are a variety of different methods available for electrical leak location. Choosing and specifying the most appropriate method requires an understanding of the technologies available: their benefits and limitations. In many applications an ELL method must be specified in the design phase, before construction starts, to ensure a successful test.

This presentation identifies the various common ELL technologies and identifies criteria which should be considered when specifying electrical leak location (ELL) methodology. Earn 1 PDH at the conclusion of the first webinar.
