Reinforced Soil Retaining Walls & Slopes

Reinforced Soil Retaining Wall Solutions

In cases where reinforced soil retaining walls and soil slope reinforcement are required, you are presented with some difficult choices. The options are varied, including reinforced concrete, mass concrete, gabions, crib walls, sheet piling and masonry. Increasingly, design engineers are looking to Tensar for a tailored solution from a single source. 


TensarTech® Earth Retaining Systems for Walls and Slopes provide a range of reinforced soil structure products 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 and to maximise the land available.


Reinforced soil retaining wall systems support a sloping soil mass using geogrids and a choice of facing (typically concrete blocks or wire mesh). This allows for rapid and economical construction, reducing conventional construction times, avoiding the need for specialist skills and often enabling the utilisation of site-won fill materials.

What is an Earth Retaining Wall?

Earth retaining walls, also known as reinforced earth 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, to relieve lateral earth pressure from adjacent structures, or to carry surcharge and live loading.

There are many types of earth retaining walls, including: gravity retaining walls, cantilever retaining walls, embedded retaining walls and reinforced soil retaining walls.

Tensar offers a range of TensarTech reinforced retaining wall systems for permanent and temporary structures.  Reinforced earth walls 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.

Bridge Abutments

In the case of bridge abutments, reinforced earth retaining walls are increasingly common to support the bank seat directly on the reinforced soil block. This transfers all bridge loading stress into the reinforced soil structure, resisting seismic loading and structural damage. Tensar reinforced earth walls for bridge abutments offer major cost savings and reductions in construction time compared to alternative methods.

Steepened reinforced earth wall slopes with a face angle up to 70°, can offer alternatives to vertical walls, at considerably lower cost. Typically these earth retaining slopes have a ‘green’ facing of grass or selected planting to enhance local identity; they are aesthetically appealing with a reduced environmental impact. 

Ultimately these types of earth retaining walls enhance the sustainability of a project. Waste or site-won materials are often suitable for the structural fill, which supports 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 reinforced soil retaining walls offer 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 of Reinforced Soil Retaining Wall

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. This cuts construction times by up to half, thus giving up to 75% cost savings.

Additionally, reinforced soil retaining walls benefit from environmental advantages, including the use of site-won or waste fill materials. They can also significantly reduce construction carbon emissions and prevent wastage with a service life of up to 120 years.

Our internationally-certified reinforced earth wall systems and products provide options of architectural and natural finishes, as well as design and component options for easily-built curves and terraces. Tensar’s full design service includes working drawings, material schedules and method statements to help your business.
