A lower cost alternative to cast-in-place and other concrete retaining walls, the SierraScape® Wire-Formed Retaining Wall System is the superior choice for appearance, performance and value. Welded wire forms, Tensar® Geogrids and a locking tail strut connecting the two work together to resist differential settlement, seismic activity and heavy external loads. Inert to chemical degradation, the high-density polyethylene (HDPE) geogrids enable a wider variety of fill materials to be used, including on-site soils and recycled concrete. And like all Tensar systems, a full range of services, including engineered drawings and site assistance, is available for SierraScape System installations.
With its limited number of components, the SierraScape System is quick and easy to install and maintain, requiring no specialized equipment or labor. Wire forms stack easily to create a uniform wall face that maintains alignment, even with varying setbacks. And since the SierraScape System can be backfilled with general embankment fills or on-site soils, materials and disposal costs are reduced as well.
One System, Two Applications
The SierraScape System can be specified for both grade separation and pressure relief applications. For structures with face angles greater than 70°, the system can save 30% to 60% over the cost of comparable concrete wall installations. And it features three facing options for complete design versatility:
