SierraScape Retaining Wall System


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.

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.

The SierraScape System can also be used for pressure relief applications to support soil and building loads below grade, providing a faster and more affordable solution. Because it effectively supports surrounding fill, lateral soil loads against the below-grade structure are eliminated. The result: lower cost foundation walls that are structurally equivalent to conventional installations, including cast-in-place.

SierraScape pressure relief walls can be specified for building foundations and existing bridges, flood walls and other new construction or rehabilitation projects. Low cost materials and speedy installation make them the system of choice to replace counterfort walls and reduce concrete reinforcement in structural foundation walls. They’re also an ideal solution to demolition/replacement of existing structures and can accommodate increased loads at facility expansions.

One System, Two Applications

  • Stone-faced – filled with native or imported stone; stone color and size can be specified to meet aesthetic requirements
  • Vegetated – typically incorporating local plant species to complement the surrounding environment. Erosion control products promote vegetation, eliminate erosion and provide long-term reinforcement of the root system.
  • Architectural – veneer treated with a stacked stone or a shotcrete-sculpted face


Sierra Slope Retention System


The Sierra® Slope Retention System provides an economic and aesthetic alternative to conventional concrete retaining walls, replacing them with natural, landscaped, sloping structures nearly indistinguishable from native terrain. These graded and steepened reinforced soil slopes (RSS) typically range from 26° to 70° from horizontal, depending upon site development conditions. Unlike flatter slopes, Sierra Slopes claim a smaller footprint as they maximize developable land, create usable land in undeveloped areas and enhance property values.

Like our other Grade Separation Solutions, the Sierra System is a mechanically stabilized earth (MSE) system. Complete and fully integrated, its components have been designed to work together for optimum efficiency and performance in a variety of site and loading conditions. Sierra Slopes significantly reduce material and installation costs by eliminating limitations imposed by varying soil properties, minimizing fill requirements and allowing the use of on-site fills. As a result, they can save up to 60% of the cost of alternative solutions such as concrete retaining walls.

And Sierra Slopes are structurally reliable. Unaffected by cracking or leaning, they’re more resistant to differential settlement or seismic activity than conventional retaining walls. Sierra Slopes are reinforced with Tensar® Geogrids; manufactured from high-density polyethylene (HDPE), this polymeric grid is inert to chemical degradation and can be used with a variety of backfill materials. Steepened slopes exceeding 45° are further secured with a combination of welded wire forms and a wrapped face of geogrid and erosion control products to provide additional stability at the face.

The Many Faces of Sierra Slopes

Sierra Slopes can be installed in the most challenging grade separation projects. Varying curves and face angles can be created for a more natural look, and a number of facing options, including plantable sod, hydroseeding, native vegetation and bioengineering, can be specified. Like all Tensar systems, the Sierra System is installed quickly and without specialized equipment or labor. To ensure successful installation, we can provide a full range of services including engineered drawings and site assistance.


Mesa Retaining Wall System


A lower cost alternative to cast-in-place and other conventional solutions, Mesa® Retaining Wall Systems have it all: the dependability engineers require, the efficient installation contractors expect and the aesthetics architects and owners demand. One of the only segmental retaining wall (SRW) systems with a positive mechanical connection between block face and geogrid reinforcement, Mesa Systems offer a full line of smartly designed, cost-effective solutions for both structural and landscape retaining wall needs.

Unlike modular block walls or other SRW systems, which mix and match components from different sources, Mesa Systems are fully integrated; every component, including high strength Mesa Units, Tensar® Geogrids and the system’s unique locking connector, was developed by Tensar International. These components are designed to work together for optimum efficiency and performance, meeting or exceeding industry standards – so much so that core fill is rarely needed.

Their block-to-geogrid connection assures full load transfer from wall face to reinforcement, resulting in unsurpassed reliability. High strength concrete blocks feature compressive strength exceeding AASHTO standards (>4,000 psi). High-density polyethylene (HDPE) geogrids, inert to chemical and electrical corrosion, withstand a variety of backfill materials.

All that makes Mesa Systems the retaining wall solution of choice, serving professionals as well as Homeowners. Independently reviewed by HITEC, Mesa Systems have received DOT approval in most states. They achieve near-vertical or 5/8" setback of the wall face. They’re available in a variety of facing options, including styles, colors, dimensions, textures and finishes. And like all of our systems, Mesa Systems are supported with Tensar’s full range of services, including engineered drawings and site assistance, to ensure successful installation.
