FOR MORE INFORMATION
Geosynthetics magazine has provided
information on the geocell specification
charts for comparative purposes only.
Designers should contact manufacturers
for additional details and to discuss sitespecific
considerations.
Information on the use and specification
of geocells is also available from the
Geosynthetic Materials Association (GMA).

PUBLISHER'S NOTE
Geosynthetics magazine compiled all
information included in the 2022 Geosynthetics
Specifier's Guide from information submitted by
firms in the geosynthetics industry. Companies
provided specifications voluntarily, and
specification accuracy is the responsibility
of the manufacturer. The appearance of a
listing in this directory is not an endorsement
of the company or product by Geosynthetics
magazine or the Industrial Fabrics Association
International (IFAI). The 2022 Geosynthetics
Specifier's Guide is intended as a guide, and
Geosynthetics magazine and IFAI encourage
readers to contact the companies listed for
further information.
Companies engineer geocells for protection and
stabilization applications. Engineers often use them to
improve the performance of standard construction materials
and erosion control treatments.
G
eocell products are three-dimensional, expandable panels made from highdensity
polyethylene (HDPE), polyester or another polymeric material.
When expanded during installation, the interconnected strips form the
walls of a flexible, three-dimensional cellular structure into which specified infill
materials are placed and compacted. This creates a free-draining system that holds
infill materials in place and prevents mass movements by providing confinement
through tensile reinforcement. Cellular confinement systems improve the structural
and functional behavior of soils and aggregate infill materials.
Development
Geocell products were developed in the late 1970s and early 1980s. The primary
geocell applications include:
* Protection and stabilization of steep slope surfaces
* Protective linings of channels and hydraulic structures
* Static and dynamic load support on weak subgrade soils
* Multilayered earth-retaining and water-retaining gravity structures
Infill selection is primarily governed by the nature and intensity of anticipated
working stresses, the availability and cost of candidate materials, and,
in some instances, the aesthetic requirements for a fully vegetated appearance.
Basic geocell infill types are aggregates, vegetated topsoil and concrete.
The numbers
Companies that submitted product data chart lines were asked to provide data
determined through industry-accepted testing methods. Companies were
asked to sign a certificate of compliance verifying the accuracy of this data.
