Title: Geocell Retaining Structures
Speaker: Richard Heritage, Geotechnical Engineer, ABG Geosynthetics Limited
JOINT MEETING with University of Manchester
Date: Monday 4th February 2019
6.00pm for 6.30pm
Geocells – also known as cellular confinement systems – are typically made from high strength polymer or dense needlepunched non woven geotextile in a ‘honeycomb’ structure which is backfilled with site won or imported soil. First developed by the U.S. Army Corps of Engineers in 1975, geocells were devised for building tactical roads over soft ground. This was then extended to stacking several geocells to create miltary bunkers filled with locally won soils to prevent blast or ram raiding during enemy attack.
Geocells have been developed for the civil market in a variety of applications including retaining stuructures – as a form of mechanically stabilised earth wall. A geocell retaining wall is constructed by stacking panels of cells on top of one another, sometimes in combination with geogrid reinforced soil where the geocells act as a flexible facing element.Geocell retaining structures can offer a number of significant benefits to traditional solutions; allowing the re-use of site won material, ease of construction with a flexible finish, significant cost savings, and environmental benefits from a green finish and reduced carbon footprint.
This presentation will look at the methods and considerations necessary in the design process for using geocell retaining walls, will discuss considerations for construction, and the advantages and disadvantages of using geocell retaining walls in different situations as told through various case histories.
