The Geosynthetic Institute (GSI) will sponsor a webinar entitled “Geosynthetic Drainage Materials: Applications, Design, Installation and Performance,” on Feb. 24, 2018, from 11:30 a.m. to 1 p.m. EDT.
Geosynthetic drainage materials consist of a drainage core (geonet or geospacer) with geotextiles bonded to one or both surfaces. Their in-plane flow capacity is equivalent to 12 inches (30 cm) of sand with a permeability of 0.04 inch/second (0.01 cm/sec) or higher. The associated cost of these materials and their installation greatly favors this type of geosynthetic alternative on myriad applications. For example, solid waste liner and cover applications, plaza decks and green roofs, retaining walls and slopes, tunnel linings, etc., all have successful history in this regard. Design considerations will be described and focus on flow rates and compressive behavior, both being standardized ASTM/ISO test methods.
Critical in their proper performance are connections and attachments along edges and ends for proper field performance. A major successful field project is presented as well as four unsuccessful projects. Lastly, a laboratory study on plastic cable ties (used to join most types of geosynthetic drains) will be presented along with appropriate commentary. Participants of this webinar will be exposed to the plethora of geosynthetic drainage materials that are currently available vis-à-vis the various applications that they service.
This webinar will be useful for consulting engineers and designers involved in the controlled flow of all types of liquids and even gases; geosynthetic and soils testing laboratory personnel; field CQA and CQC personnel for both materials and installation practices; owners and operators of solid and liquid waste facilities, as well as many other public facilities; and federal, state and local regulators in both environmental and transportation sectors of their respective mandates
The webinar will be taught by Dr. Robert M. Koerner, professor emeritus of civil engineering at Drexel University and director emeritus of the Geosynthetic Institute.
Webinars cost $200.00 for GSI members and $250.00 for nonmembers. Successful completion of a multiple-choice test after the webinar carries 1.5 professional development units.
