Retaining wall on reinforced soil SIERRASCAPE®

galvanised steelreinforced concretebin-type

Overview

Tensar SierraScape® is a wire-basket, mechanically-connected reinforced-soil retaining wall system designed to address a wide range of project and site conditions. The system combines galvanised wire-formed baskets with Tensar uniaxial (RE500) geogrids and a compact set of components to enable fast installation, settlement tolerance and load resistance.

Key product highlights

• Three facing options: stone-faced, vegetated and architectural finishes.
• Welded wire-face system with a mechanical connection between facing and reinforcement.
• More than 1.8 million m² of wall face installed worldwide.

Benefits

• Adapts to varied site conditions and aesthetic requirements.
• Improved resistance to differential settlement, seismic loading and heavy external loads through the mechanical basket–geogrid connection.
• Simplified installation with a limited number of components, reducing the need for specialised equipment and enabling use of local fill materials.
• Versatile finish options (vegetated, stacked-stone, shotcrete-sculpted or stone-faced) for visual integration with surroundings.
• Can be used for pressure-relief structures and as a cost-effective alternative to reinforced concrete solutions in many projects.

System components

• Tensar uniaxial RE500 geogrid (high-orientation HDPE resin to resist long-term tensile deformation).
• SierraScape galvanised wire-forms (stacked wire baskets / welded wire faces).
• Locking tail strut (SierraScape component to maintain facing alignment).
• Geotextiles and Tensar biaxial geogrids for vegetated surface options.
• Erosion-control mats and ancillary components.
• Engineering design and site assistance (design support, detailing and construction support available).

Technical specifications

• Primary reinforcement: Tensar RE500 uniaxial geogrid — high tensile capacity in the principal direction; open aperture for interlock with natural fill.
• Facing: galvanised welded wire-forms filled with native or imported stone when a stone face is specified; vegetated or architectural veneers also available.
• Mechanical connection: proprietary connection between wire baskets and geogrid to enhance performance under settlement and seismic conditions.
• Installation: stacked welded wire-forms compatible with general embankment fills or on-site soils; minimal specialised labour or equipment required.
• Applications: retaining walls and slopes, pressure-relief structures, demolition/replacement and facility expansion projects.
