The Geosynthetic Institute (GSI) will sponsor a webinar, “Geosynthetic Drainage Materials: Applications, Design, Installation and Performance,” on Jan. 22, from 11:30 a.m. to 1 p.m. EST. Geosynthetic Materials Association (GMA) member companies and their employees receive discounted rates on all GSI webinar and short course registrations.
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 (300 mm) of sand with permeability of 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. Design and testing issues will be illustrated and explained. Methods of field connections and attachments will be described, particularly the use of plastic cable ties. Successful field projects, as well as four unsuccessful ones, will be illustrated in the context of “lessons learned”.
The webinar is intended 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 construction quality assurance (CQA) and construction quality control (CQC) personnel for both materials and installation practices
- Owners and operators of solid and liquid waste facilities as well as many other public facilities
- Federal, state and local regulators in both environmental and transportation sectors of their respective mandates
Webinars cost $200.00 for GSI and GMA members, and $250.00 for nonmembers. Successful completion of a multiple-choice test after the webinar carries 1.5 professional development hours (PDH).
