Presenter: Eric Blond, P.E.
This webinar will introduce the current practice for testing and designing drainage geocomposites considering the recommendations of the current ASTM or ISO design guidance. There are several types of drainage cores currently on the market: biplanar geonet, triplanar geonet, box-shaped geonet, multilinear, dimplesheet, geomat and structured geomembrane. Their hydraulic properties are typically defined using ASTM D4716 or ISO 12958.
These test methods will first be described in detail. The influence of boundary conditions, normal load, hydraulic gradient and seating time on the measured flow capacity will be discussed, e.g. why test using a 100 hours seating time between soft boundary instead of 15 minutes seating time between rigid surfaces.
The concept of long-term flow capacity will be introduced, as described in GRI GC8, ASTM D7931 (2018) and ISO 18228-4 (2020, in press). Methods used to determine the creep, biological and chemical reduction factors will be presented.
