Boardwalks
Durable, Sustainable, Slip Resistent Boardwalks from British Recycled Plastic are designed to withstand the toughest environments, providing a long-lasting, sustainable solution with a 25 Year Guarantee.
Recycled plastic boardwalks, fishing pegs and dipping platforms are loved by parklands, conservation projects, wetland reserves and angling clubs up and down the UK.
Made from durable materials, our boardwalks offer exceptional resistance to weathering, rotting, and wear, ensuring decades of reliable performance. With a high slip-resistance, even in wet conditions, our boardwalks provide a safe surface for pedestrians, wheelchair users, cyclists, and more. Our planks, posts and decking boards are resistant to the growth of mould and algae. This considerably reduces the slip-risk when compared to timber, removing the need for annual jet washing or chicken wire overlays. Our recycled plastic artificial lumber is also resistant to UV-fading and will never rot, split or splinter.
Please note: There are no British Standards that refer specifically to boardwalk design, however, the following represents best practice when using recycled plastic lumber in their construction. This is born from many years of experience and takes into consideration the differences between this material and traditional timber.
Please use our tool to calculate guideline quantities for your recycled plastic boardwalk project.
INGREDIENTS:
All measurements are in millimetres (or metres when discussing overall length).
- Standard 150mm x 40mm (or 150mm x 38mm) decking profiles
- 100mm x 100mm posts
- 120mm x 50mm (or 125mm x 50mm) Stringers
- 120mm x 50mm (or 125mm x 50mm) Joists. Joists are sometimes referred to as Beams, Cross Beams or Cross Members.
- If no railings are required, 50mm x 50mm kickboards (also called toe boards by some customers) are usually used. Some customers may prefer 100mm x 50mm boards fixed vertically, but this is seldom requested.
If the boardwalk requires railings, we would use 100mm x 100mm posts and 100mm x 50mm rails. If the customer is a skilled joiner they may want to just extend the posts upwards from the ground and through the boardwalk, but generally they will use a steel post shoe like this example, screwed or bolted into the boardwalk surface if the amount of railings is small. https://www.ironmongerydirect.co.uk/product/timco-bolt-down-fence-post-shoe-quick-fit-100-x-100mm-galvanised-300616

Notes regarding heights of railings on boardwalks.
Where boardwalks are publicly accessible, best practice is that where the boardwalk height above ground is 400mm or more there should be railings.
If the boardwalk is for pedestrian use, the railings should have a height of 1000mm to 1100mm. If the boardwalk is frequented by cyclists or horse riders, the height of the railing should be 1400mm to 1500mm to take into account their higher centre of gravity.
Generally, where there are no railings and the boardwalk is publicly accessible, a kickboard would be in place. If there are railings, there would not usually be a kickboard.
How we arrive at our calculations
For ease, we will assume that these are relatively straight boardwalk runs, although it should be noted that recycled plastic is an ideal material to build in gentle curves.
Corners, junctions and passing places are not included in these calculations as there are too many variables to cover.
Thing to always consider:
- The legs should be no more than 1500mm apart along the boardwalk length
- Around one third of a leg should be in the ground
- The “centres” of the stringers, (centres are a measure of a span from the centre of one object to the centre of another), should be no more than 500mm under standard 40mm decking. If the centres are greater, the decking won’t break but it can feel too springy for some users.
- Each decking board should have a gap of between 5mm and 10mm between them for drainage. A 10mm gap has been included in the calculator.

Why is British Recycled Plastic The Best Choice For Boardwalks?

Recycled Plastic: The Ideal Boardwalk Solution for Challenging Locations
Recycled plastic artificial lumber is the ultimate material for boardwalks in wet, hard-to-reach areas. Unlike traditional timber, which typically lasts only 5 years in aquatic environments, recycled plastic far outperforms, offering unmatched durability and longevity.
Boardwalks and platforms constructed with our recycled plastic products are built to last for decades. With our 25-year guarantee, and when paired with high-quality stainless steel fixings, they could endure for 50 years or more.
Recycled Plastic Boardwalks: Safe and Accessible Solutions for Waterlogged Areas
Designed for areas prone to waterlogging, flooding, or unsafe terrain, recycled plastic boardwalks provide safe and accessible pathways for pedestrians, wheelchair users, and cyclists alike. These versatile structures can be installed directly on the ground, with joists resting on the surface, or elevated on posts to ensure clearance in wetland or flood-prone zones. For added safety, toe boards (also known as kicker boards) can be installed to prevent slipping at the edges, and handrails can be added at heights suitable for the primary users.
When wheelchair access is required, deeper toe boards can be incorporated, and small turning platforms can be added for ease of navigation. If your site offers public access, we recommend familiarising yourself with local authority safety regulations to ensure compliance.


Requesting a Quote for a Recycled Plastic Boardwalk
To provide you with an accurate quote for your recycled plastic boardwalk, we ideally need a cutting list for the artificial lumber planks and posts. Alternatively, if you know the desired length, width, handrail specifications, and the height above the ground, we can offer a guide price along with suggestions for the most suitable installation options.
Please note, while we are happy to assist with pricing and recommendations, the design and appropriateness of the structure for your location is your responsibility. This isn’t us being difficult—each site has unique considerations, making a “one size fits all” approach impractical. However, we do have standard drawings available for a typical 1500mm wide boardwalk to help guide you.
Remember, factors such as the ground conditions, site function, and public access requirements can vary greatly. If your boardwalk will be open to the public, there are specific regulations you’ll need to take into account for safety and compliance.
Design Considerations for Recycled Plastic Boardwalks
Local regulations can vary, but generally, a handrail is required when the boardwalk is more than 400mm above the ground. For boardwalks used by pedestrians and wheelchair users, the handrail is typically set at 1100mm in height, while a height of 1400mm is more appropriate for cyclists or horse riders.
If your boardwalk will accommodate wheelchair users, it’s important to include passing places and turning circles in your design. Even if the boardwalk is 400mm or lower, kickerboards (toe boards) are often required for public access, to ensure safety for wheelchair users and people with prams or buggies.
While most customers opt for decking boards to create the boardwalk surface (as shown in our drawings), there are alternatives. Flat boards are often preferred in areas with a high volume of wheeled traffic. Regardless of your choice, all our recycled plastic planks are chemically inert, preventing algal growth, and providing excellent slip resistance in all weather conditions, whether flat or grooved.

We’d expect it to last several decades, probably 40-75 years if you build it well.
The grooves on the surface should always be laid across the direction that people will walk. Where used over water, the grooves should always be parallel to the bank
500mm centres are fine
Allowing for a 10mm gap between boards, each decking plank can be roughly counted as half a square metre.
Recycled plastic boardwalk parts should always be stored laid flat on delivery, until you assemble them.
I’m afraid we don’t design and install ramps, platforms or boardwalks. We just manufacture and supply the boards.
Our recycled plastic does, however, cut and perform in a similar manner to hardwood planks, so the people you would normally use to make this if it were wood should be able to construct it from recycled plastic.
We would be happy to give you a price for the material and can cut it to size if you would like to supply a list of the planks you need. We are also happy to talk to any installers/joiners/volunteers on the phone if they would like additional support.
