Minimum short-term seam peel strength requirements and long-term performance of geocell junctions
October 20th, 2023
Internal geocell junctions, also called seams, play a critical role in ensuring that a geocell system will perform uniformly and consistently across the footprint of a stabilized area. In load support applications, non-uniform junction performance can lead to differential settlement and localized subsidence. This can lead to serviceability issues, damage to the overlying structure/pavement, and […]
Slope stability with geocells at a New Zealand playground
December 27th, 2021
Photograph courtesy of Cirtex Aronia Park is a colorful new playground in South Auckland, New Zealand, that includes two multihued slides. The challenge arose with the specified topsoil thickness for the steep slope beneath the slides. There was a risk of the slope soil sliding off and requiring costly repair. Greenscene, the contractor, approached Cirtex […]
Rebuilding roads, replacing transmission lines damaged during Hurricane Michael in Florida’s Panhandle
March 1st, 2019
Hurricane Michael caused extensive damage to Florida’s power grid network, leveling more than 100 transmission towers in a 34-mile (55-km) right-of-way from Port St. Joe to Callaway. This right-of-way crosses swampy, remote and hard-to-reach areas, making rebuilding the grid even more challenging. This extremely wet, muddy ground prevented Duke Energy repair vehicles from accessing the […]
Presto releases geocell ballast research
June 1st, 2018
Presto Geosystems, manufacturer of the high-density polyurethane (HDPE) GEOWEB® geocell base stabilization system, has released results from railroad-track research performed to quantify the reinforcement benefit of GEOWEB-confined ballast as compared to unconfined ballast. The company said the research was a cooperative effort under the direction of Ben Leshchinsky, Ph.D., P.E., of Oregon State University, and […]
