New Mexico State Highway And Transportation Department Highway 544 widening project (located between the towns of Aztec and Bloomfield, New Mexico) specified the GEOWEB Cellular Confinement System. With a severe pitch of 1.5:1 on this cut slope, the four inch deep cell depth version of the GEOWEB System was chosen as a cost-effective solution for this steep slope protection project. The GEOWEB System was installed in 1994 in order to protect the face of the slope and continues to perform up to expectations.

Erosion Protection of Steep Cut Slopes - Case Study
In May of 1995, 70,000 sf of large-cell (GW40V) GEOWEB® slope protection system was utilized on Phase II of the Cyprus Miami Open-Pit Mine to stabilize the cut slopes upon completion of copper extraction at the site. Aggregate available on site was used to infill the GEOWEB 3D structure and provide erosion resistance and slope-surface stability on slopes with 70-ft. slope lengths, and as steep as 1H:1V. The GEOWEB system reduces environmental impacts by limiting stormwater runoff, soil loss, and impacts to...
Articulated Concrete Blocks for Shoreline Protection
Shoreline erosion is a process that occurs naturally along the coast and on lakes, rivers and even streams. Shoreline erosion can occur slowly due to the constant bombardment of waves against the shore, the flow of water, runoff due to rain and the freezing and thawing of ice. It can also occur quickly due to storms, flooding and other more extreme weather conditions. Shoreline erosion is a constant concern to homeowners and cities or communities along shorelines because it can result in property damage, harm to...
The Basics of Slope Stability Analysis for Geosynthetics
Slope stability analysis is vital to preventing slope failures in a variety of engineering applications including landfill design, roads, dams and embankments, to name a few. Proper analysis anticipates both natural and manmade slopes and failure of foundations and retaining walls. This blog covers the necessity of slope stability analysis, how to conduct the analysis and the role of geosynthetics in slope stability. Slope Stability Meets Four Key Objectives The geometry of the slope, incorporated materials,...
Geodrilling: Maintenance of active slope stability installations
Landslide activity and slope failure on parts of the Isle of Wight have been an ongoing problem for hundreds of years and a significant landslide during the particularly bad winter of 1994-5 seriously affected an area up to 400 metres inland from the coast. Instability in the Castlehaven area had to be addressed to reduce the risk to public safety, property and the local infrastructure. The Isle of Wight Castlehaven Coastal Protection project team chose a siphon drain® system, an innovative solution for...
Geotex® 4x4 used in Missouri slope failure repair project case study
In 1993, flooding in an adjacent stream caused a slope failure along a 300 foot section of Old Highway 100 in Franklin County, Missouri.Many attempts were made over the years to stabilize the slope and roadway, and none were successful. Flooding caused the slope that supported the highway to give way and become hazardous.A porous concrete slope protection facing was used to cover approximately 9,000 square yards of high-strength Geotex® 4x4 woven fabric from Propex™. The combination of the geotextile...
