Solutions that help roads perform safely, reliably and for the long term
Road projects face unique challenges, from constrained corridors and changing ground conditions to the need to keep traffic moving. We support designers and contractors with practical engineering solutions that are straightforward to build and perform reliably over the long term.
Whether you’re upgrading existing routes or delivering new infrastructure, we can help support road projects of all scales and complexities.
- Retaining walls alongside highways and local roads
- Bridge abutments and flyovers
- Road embankments and cuttings
- Underpasses and culverts
- Pavement and subgrade reinforcement
- Slope stability and protection works
- Flood, erosion and scour protection
From early ground challenges to long‑term asset performance, we help make complex road infrastructure projects achievable.
Roadside excavations and changes in ground level can introduce instability if not properly managed. We provide retaining wall solutions that help stabilise soft or variable soils, protect road infrastructure and reduce the risk of slope movement.
Reinforced Earth® systems are widely used to create safe, resilient and adaptable retaining structures, whether as single‑tier walls or multi‑tiered arrangements for more complex schemes. These solutions can be designed using steel or geosynthetic soil reinforcement and accommodate a wide range of backfill materials. Where required, our precast retaining systems also provide efficient, space‑saving alternatives.
Building road embankments often involves challenging ground conditions and strict spatial constraints. Using geogrid‑reinforced solutions, we help deliver embankments that are stable, buildable and cost‑effective.
Our engineered solutions support:
- Embankments constructed over soft or weak soils
- Embankments built over piled foundations
- Embankments spanning areas affected by voids or subsidence
By strengthening the soil mass, these approaches improve performance while reducing the need for extensive ground replacement.
Understanding soil behaviour under long‑term traffic loading is critical to the performance of road infrastructure, particularly where bearing capacity is low. Our geogrid reinforcement systems, combined with specialist engineering support, help stabilise soils and deliver reliable pavement performance even in the most demanding conditions.
Compared with traditional construction methods, geogrid‑reinforced solutions can significantly reduce excavation requirements and the volume of aggregate needed. This improves buildability and efficiency, and lowers maintenance demands over the service life of the road.
The transition between road embankments and bridge decks is a critical part of many highway schemes. Our retaining wall systems are widely used for access ramps and bridge approaches, providing reliable load distribution and accommodating settlement where required.
Whether supported on fill or piles, our earth‑retaining solutions are well suited to the specific demands of bridge abutments. They offer flexibility in design and construction, helping engineers respond to ground conditions, geometry and structural loading with confidence.
As traffic levels increase, road networks often need to be widened while remaining operational. Our retaining wall and reinforced soil solutions allow carriageways to be expanded where space is limited or where existing embankments are present.
Shored systems enable new retaining structures to be connected to existing ones, making them particularly effective for widening projects. Geogrid‑reinforced solutions also offer an economical way to extend roads over soft ground, reducing excavation, material use and construction time while maintaining service continuity.
New roads and highway upgrades often pass close to residential areas, where managing noise is an important consideration. Our sound wall solutions help reduce the impact of traffic noise while remaining straightforward to install, even in constrained environments.
What you can expect when you work with us
Safety‑led construction methods
Designed to reduce risk, our systems limit site traffic, remove manual handling of facings and allow construction from the soil face, helping keep operatives safely away from live traffic, water and other hazards.
Flexible for constrained sites
Our retaining walls, embankments and tunnel solutions make efficient use of space, helping road schemes progress where boundaries and corridors are limited.
Reliable in challenging ground
From soft soils to complex ground conditions, our systems manage settlement and distribute loads effectively, supporting stable and dependable road infrastructure.
Lower carbon, lower impact
Our solutions reduce the amount of concrete required, helping lower embodied carbon, and can incorporate noise‑absorbing layers to support quieter, more considerate road infrastructure.
Well‑designed road infrastructure supports safer journeys, stronger connections and the communities around it
