Performance Testing — Aggregate Infill
Geoweb® Cellular Confinement Systems with aggregate fill are used for applications such as
load support, earth retention, porous pavement, and slope and channel erosion protection. A
testing program was carried out at the Colorado State University Hydraulics Laboratory to
quantify performance of polyethylene Geoweb® in erosion protection, develop engineering
guidelines for product usage, and compare results to rip -rap stabilization procedures for
channels.
