Overview

Bison replaced a decayed timber platform and boardwalk for the RSPB at Middleton Lakes with the highly durable Re-Life 100% recycled plastic structure that blends beautifully with the landscape. Installed on ground screws, it required no concrete or digging, meaning there was no mess.

Challenge

In support of RSPB's long-standing environmental goals, Bison was commissioned to replace a deteriorated timber platform and boardwalk at the Silt Pool Lookout in Middleton Lakes Nature Reserve.

The brief was clear: design and install a more durable, low-maintenance alternative that would blend into the natural surroundings and have minimal ecological impact.

Solution

Bison Bridge's solution was a 100% recycled and 100% recyclable Re-life plastic platform and boardwalk, supported by low-impact ground screw foundations - a perfect fit for wetland environments and nature-sensitive sites.

Work required

  • Dismantle and dispose of an existing decayed timber platform and adjacent boardwalk

  • Supply and install a like-for-like structure using sustainable, long-life materials

  • Avoid excavation or heavy machinery that could disrupt habitats

  • Ensure safe, non-slip public access and seating

  • Deliver a solution that aligns with the RSPB's ecological values

Benefits of Re-life plastic

Re-life plastic is a high-quality material that is:

  • 100% recycled and 100% recyclable

  • Splinter-free and rot-proof, even in consistently wet environments

  • Extremely durable, making it ideal for high-footfall public sites

  • Low-maintenance, with no painting or treatment required over time

By replacing timber with Re-life recycled plastic, the company ensured that the new platform offers long-term resilience without compromising on appearance or function.

Construction highlights

Bison's experienced team delivered a complete removal and rebuild solution using a sustainable approach.

Key build elements

  • Ground screws, installed to layout drawing – no concrete, no digging

  • Re-life plastic bearers, bolted between supports

  • Re-life joists, mounted on bearers and screwed for strength

  • Re-life deck boards, offering safe, slip-resistant access

  • Re-life kickrails, for added security along both sides of the deck

  • A dual-rail barrier and top leaning rail, creating a safe, comfortable viewing point

  • 3 fixed benches, crafted from Re-life plastic to replicate the original timber design

Low-impact foundation system

To support this eco-friendly structure, Bison used a ground screw foundation system, eliminating the need for excavation or concrete. Ground screws offer:

  • Immediate load-bearing capacity

  • Minimal ground disturbance

  • Year-round installation, even in wet or remote locations

  • Reduced embodied carbon, compared to concrete bases

Together with recycled plastic materials, this approach provides a truly sustainable, long-life solution for outdoor platforms and boardwalks.

Outcome

The new platform and boardwalk deliver enhanced safety, stability and environmental performance. Visitors to RSPB Middleton Lakes can now enjoy a splinter-free, rot-proof and weather-resistant structure that fits effortlessly into the reserve's landscape.

With no ongoing treatment or upkeep required, the RSPB team can focus on conservation, not repairs.
