Earth Retaining Walls & Reinforced Slopes

Walls & Slopes

Tailored solutions from a single source

When it’s important to maximise the land available, and site terrain is sloping, design engineers have some difficult choices. Where earth retaining structures are needed, options are varied, including reinforced concrete, mass concrete, gabions, crib walls, sheet piling and masonry. 

Increasingly, designers and contractors look first to Tensar for a tailored solution from a single source – TensarTech® Earth Retaining Systems for Walls and Slopes: a range of reinforced soil structures with a choice of faces to suit local design codes, budget, environmental constraints and aesthetic requirements. They are designed as ‘true systems’ using carefully integrated components for superior structural integrity 

Each system is based on reinforcing a soil mass with Tensar® uniaxial geogrids allowing rapid and economical construction, reducing conventional construction times, avoiding the need for specialist skills and often enabling the utilisation of site-won fill materials.

Earth Retaining Walls and Bridge Abutments 

Earth retaining walls support a mass of earth, to form a vertical or near vertical face. They may be required on a sloping site to create terraces with minimum footprint, or to relieve lateral earth pressure from adjacent structures. They may be required to carry surcharge and live loading, or in the case of integral bridge abutments, the full vertical and horizontal deck loading. Tensar offers a range of TensarTech wall systems for permanent and temporary structures. They are designed as reinforced soil (or mechanically stabilised earth MSE) structures with a choice of facing –modular concrete blocks, segmental panels full-height concrete panels or wire mesh options.

Steep Slopes

Steepened earth slopes with a face angle up to 70°, can offer alternatives to vertical walls, at considerably lower cost. Typically having a ‘green’ facing of grass or selected planting to enhance local identity, they are aesthetically appealing with a reduced environmental impact. To enhance the sustainability of a project, waste or site-won materials are often suitable for the structural fill, which support both reductions in costs and essential long-term sustainability goals.

Slope Repair 

Failed slopes are common, and changing rainfall patterns due to climate change seem likely to increase such occurrences around the globe. Excavation and replacement of failed materials has been the most common approach for reinstatement of slopes, up to now. Tensar offers a cost efficient alternative, often re-using the failed materials to repair the slope, as well as incorporating geogrid reinforcement to provide stability and resilience.

The Benefits 

Compared to alternative structural solutions, TensarTech® Earth Retaining Systems – with a choice of face angles from 20˚ to 90˚ - offer rapid construction, usually needing no crane lifts or temporary propping, cutting times by up to half, thus giving up to 75% cost savings. Additionally, the environmental advantages can include the use of site-won or waste fill materials and significantly reducing construction carbon emissions 

The internationally-certified systems and products provide options of architectural and natural finishes, as well as design and component options for easily-built curves and terraces. The full design service – including working drawings, material schedules and method statements, has a life of up to 120 years.
