Our office is closed 25th December until January 4th.

UK’s tallest and longest reinforced soil structures

Reinforced Earth Company were asked to provide our specialist technical services to undertake the design of 15 separate structures using a combination of products and techniques developed with our group. We supplied 15,500sqm of pre-cast faced walls, 1,600sqm of steep slopes and 110m of cut and cover tunnels. The central reserve wall is a record 1,500m in length and stands up to 8m in places and the headwalls above the arches are a record breaking 33m tall.

The Heads of the Valleys dualling project is one of the Welsh Government’s key drivers for promoting social and economic regeneration in the area. The exisiting A465 was built in the 1960s and is a single 3 lane carriageway with two lanes in uphill directions and one in the downhill. A regional traffic study in 1990 identified the need to improve the road. The improvment to the A465 is critical to the regeneration of the Heads of the Valleys area. Full details here

Reinforced Earth designs for structures using two types of soil reinforcing strips, high adherence galvanized steel strips and geo-synthetic straps, a polymeric reinforcing strip. A mixture of pre-cast and wire mesh facing were used and pre-cast arch segments.

Walls to protect the railways

Reinforced Earth Company is ready and raring to protect the railways in the UK with its retaining wall structures.

On the Borders Railway, Reinforced Earth provided 26 structures – 9,600m2 of retaining walls of which seven structures and 5,000m2 of walls directly supported the rail lines. This included work on overbridges, underbridges, railway flyovers, footbridges and stations.

Reinforced Earth structures absorb the vibrations induced by passing trains inherently well as evidenced by numerous tests in the USA, France and Germany. This is especially critical for high-speed railway lines, such as LGV SEA where Reinforced Earth walls support the high-speed track up to speeds to 320 kph.

The railway applications use the same technologies as those used for roads. However, design is modified to take into account specific requirements concerning the surcharges or coefficients of safety, especially for high-speed trains.

Essex Road, Hoddesden

Reinforced Earth designed and supplied the materials for a unique aesthetic panel that matched local architecture. The thin walled, low carbon Reinforced Earth pre-cast panels and the recycled backfill provided the client an exceptionally versatile product using our EcoStrap fully geo-synthetic solution. Osborne contractors and the client Hertfordshire County Council were delighted with the final product. Full case study can be found here

Reinforced Earth designs for structures using two types of soil reinforcing strips, high adherence galvanized steel strips and geo-synthetic straps, a polymeric reinforcing strip. EcoStraps were the choice of reinforcing straps here due to the recycled content in the back fill.

Aesthetic Developments Using Reinforced Earth 24th February 2021

With over 60million sqm of installed pre-cast and green faced retaining structures, we have amassed an enviable global position on almost any type of finish required. The webinar delves into the many factors that ensure an optimum solution is met for the client and uncovers some of the best architectural and client designed Reinforced Earth features across the world.

World Record 5MJ Rockfall Impact

Three years of research subjected to a few seconds of truth

The excitement was palpable at the Montagnole rockfall test site near Lyon, France on June 16.

Three years of collaborative research combining the expertise of Terre Armée and Gustave Eiffel University (formerly IFFSTAR) teams were distilled to a decisive moment of a mere five seconds.

The premise of thesis and the particularly slender rockfall protection bund using the Reinforced Earth® technique would either be shattered or withstand the test.

More than a dozen people stood and watched holding their breaths as the giant 12.4-tonne block was released from the crane at 41 m height with a clicking sound, then hit the structure a few seconds later, at no less than 103 km/h, resulting in an impact of 5.1 megajoules.

They saw all their hard work rewarded by a bund standing solidly; the big block – taller than an adult – now looking tiny in comparison, firmly embedded in the 15 m x 3 m x 6 m bund.

BBA / HAPAS Certification for GeoStrap polymeric reinforcement and high adherence version

With over 60,000sqm of installed structures in the UK alone, among which is the 32m high tiered retaining wall on the A465 Heads of the Valleys Reinforced Earth continues to develop innovative solutions. High Adherence polymeric straps GeoStrap HA is one of those developments which reduces carbon emissions, use of site won materials and reducing bearing pressures on foundation soils. Our updated and new additions to our certification with the BBA/HAPAS supports our investment in innovation and retains Reinforced Earth’s market leadership.

Reinforced Earth Company support mining charity

In September Reinforced Earth celebrated their 45^th year in South Wales, showcasing their record breaking engineered structural solutions on the Heads of the Valleys A465 project. The day culminated in a presentation by Professor Peter Styles, an eminent geologist and leading authority on many geophysical activities including the UK coal mines. Rather than taking a direct fee, Prof.Styles kindly asked if Reinforced Earth support the Coal Industry Social Welfare Organisation (CISWO). CISWO support former coal mining families and communities to reduce disadvantages.

Janine Wallage from CISWO thanked Reinforced Earth and Prof Styles for their generous donation and for sharing his knowledge of the industry.

Reinforced Earth are the market leaders in retaining walls, precast arches, bridge abutments, green walls and noise barriers.

Reinforced Earth and Costain Roadshow 18th September 2019

Don’t miss the chance to attend a site visit at the A465 Clydach Gorge being constructed by Costain using Reinforced Earth architectural styles panels than span more than 1km. Meeting at Big Pit, there will be chance to see historical and modern construction practices, with presentations and a key note talk from eminent geologist Prof Peter Styles

A6 Manchester Airport Relief Road

Reinforced Earth designed and supplied the materials for 9 bridge structures along the 10km length of new road. In total 2,900 m² of TerraQuad pre-cast concrete panels with a Garonne finish were provided over a mixture of bridge abutments with wing walls and retaining walls to conventional mass concrete abutments on road, rail and pedestrian bridges. Copings were also designed and supplied on various structures.

Reinforced Earth designs for structures using two types of soil reinforcing strips, high adherence galvanized steel and GeoStrap, a polymeric reinforcing strip. Steel reinforcing strips were used in the design for structures with high concentrated loads and GeoStrap used in the design in areas that are subject to normal loading conditions. The retaining walls were constructed by sub-contractors CT Construction, specialist in Reinforced Earth retaining wall construction.

Longest Reinforced Earth retaining wall in the country!

Designed and supplied by RECo on the A465 Heads of the Valleys Section 2 (Gilwern to Brynmawr), currently being constructed by Costain on behalf of the Welsh Assembly.

The 1.5 km long central reserve retaining wall stretches up the Clydach Gorge valley floor to support the new improved and safer Heads of Valleys road.

The complex site geology meant that different solutions needed to be found along the corridor and to minimize excavation into rock. One solution involved the design of a unique panel system which acts as the facing for the Reinforced Earth system behind.
