Foundations for Bridges, Footbridges & Pedestrian Crossings
RADIX screw piles and ground screws provide fast, reliable, and low-impact foundations for timber, steel, and composite bridge structures. From garden bridges and boardwalk crossings to full-span pedestrian and canal bridges, our engineered systems deliver secure, durable performance in a wide range of ground conditions.
Bridge structures demand foundations that are reliable, durable, and efficient to install, often in locations where traditional concrete footings are impractical or environmentally disruptive. RADIX screw pile foundations provide a proven, low-impact alternative, delivering high load capacity with rapid installation and minimal ground disturbance.
From lightweight footbridges to full vehicle crossings, our systems are engineered to perform in varied and challenging ground conditions, including soft soils, wetland environments, and areas with restricted access. With no excavation, no wet trades, and no curing time, RADIX foundations enable faster project delivery while protecting sensitive landscapes and waterways.
Whether supporting timber, steel, or composite structures, each installation is backed by engineering support, verified load data, and stringent QA processes, ensuring a secure, long-lasting foundation for every type of bridge project.
Canal and River Bridges
Canal and river crossings often present unique challenges – limited access, soft or saturated ground, environmental constraints, and the need for fast, low-disruption installation. RADIX screw piles and helical foundations provide a dependable, high-capacity solution for these conditions.
As the UK’s largest stockist of screw piles, with nationwide installation teams and specialist equipment, RADIX is equipped to support canal bridge projects of all scales, from small watercourse crossings to heavier pedestrian or service bridges.
Our engineering team evaluates every project based on ground conditions, structural requirements, and load testing data. With the use of helical piles and high-torque installation, RADIX foundations can achieve significant load capacity, making them suitable even for larger or more demanding bridge structures.
Speak to our engineering team and we’ll assess the site, determine feasibility, and recommend the most efficient foundation strategy for your canal or river bridge project.
Footbridges & Pedestrian Bridges
Footbridges and pedestrian crossings require foundations that are dependable, adaptable, and efficient to install – often in locations where access is limited or ground conditions vary. RADIX screw piles provide a rapid, cost-effective, and low-impact solution tailored to the specific demands of each bridge design.
Working closely with planners, engineers, and project teams, we develop a foundation strategy that delivers the required load performance while minimising disruption to the surrounding environment. Our role is to design, supply, and install the foundations; your bridge specialists handle the superstructure installation, creating a seamless process from groundworks to final completion.
Every pedestrian bridge has unique structural and environmental requirements, and our engineering-led approach ensures each project receives the exact foundation specification it needs for long-term stability and safety.
Garden & Landscape Bridges
Garden bridges, park crossings, and decorative landscape structures require foundations that are stable, discreet, and sympathetic to their surroundings. RADIX screw piles provide the ideal solution – offering strong, durable support while minimising disturbance to planting, water features, and established landscapes.
Unlike traditional concrete foundations, screw piles can be installed cleanly and quickly with small, low-impact equipment, making them perfectly suited to tight spaces, landscaped gardens, and environmentally sensitive areas. Their precision and adjustability ensure accurate alignment for timber, steel, or composite garden bridge structures.
Whether it’s a small ornamental bridge over a pond, a crossing within a public garden, or a feature bridge as part of a wider landscape design, our engineering team specifies the appropriate pile type, size, and installation method to guarantee long-term stability without compromising the surrounding environment.
RADIX delivers a neat, efficient, and environmentally responsible foundation solution that blends seamlessly into landscaped settings, ensuring your garden or park bridge not only looks exceptional but stands securely for years to come.
