Ground Screw Foundations: A Smarter Start for Bridge and Boardwalk Projects

At Bison Bridges, we specialise in the manufacture of long-life, steel-beamed bridges and boardwalks—supplied in kit form for efficient installation. For many projects, especially those in remote or sensitive environments, ground screw foundations offer an ideal groundwork solution.

What Are Ground Screws?

Ground screws are a fast, low-impact alternative to traditional concrete foundations. Made from responsibly sourced steel, they’re driven directly into the ground—no digging, no concrete, and no curing time required.

This makes them perfect for projects like:

• Pedestrian and cycle bridges
• Bridleway crossings
• Wetland or woodland boardwalks
• Sloping or hard-to-access ground

Whether you’re working in a remote nature reserve or on a time-sensitive infrastructure job, ground screw foundations can help you start strong and stay on schedule.

A More Sustainable Groundwork Option

With the construction industry under pressure to reduce carbon emissions, ground screws present a cleaner alternative. Concrete production is responsible for around 10% of global CO₂ emissions. In contrast, modern ground screws typically carry less than 50% of the embodied carbon compared to a concrete base of the same capacity.

That makes them a great fit for environmentally conscious developments—and an effective way to reduce the overall footprint of a bridge or boardwalk installation.

Reliable, All-Season Installation

One of the biggest advantages of ground screws is their flexibility. They can be installed year-round, in any weather, with minimal disruption to the site. This is particularly useful for:

• Ecologically sensitive environments
• Sites with limited access for concrete delivery
• Projects with tight timelines or seasonal constraints

They also enable quicker progress toward installing prefabricated structures—like Bison’s modular steel bridges and boardwalks.

A Smart Match for Bison Bridges Systems

Bison Bridges are designed to be straightforward to install, and ground screw foundations complement that approach well. While we focus on the superstructure—bridges and boardwalks themselves—we’re always happy to advise on compatible groundworks like ground screw systems.

They’re a solid choice for projects that need to be fast, flexible, sustainable—and built to last.
