Heronrib Duckboard Vinyl Matting

What Heronrib does before a wet shower floor becomes a health hazard

For as long as there have been communal showers and changing rooms, there have been duckboards — slatted wooden boards laid down to keep bare feet up out of the water. The idea is right; the wood is the problem. Timber slats soak up water, go slimy underneath, splinter with age, and become a home for the athlete's foot fungus that thrives on shared wet floors.

Heronrib is a duckboard reimagined in vinyl. Like a good slatted board, it holds you up above the wet floor: its open-grid body, built from nonporous extruded PVC sections, lets water drain through and clear away beneath while you stand on a firm, embossed surface. Unlike wood, it's non-porous and carries anti-bacterial and anti-fungal additives, so it doesn't rot, splinter, or breed what wood breeds.

In a shared, barefoot wet area, that hygiene difference is the whole point. Cleaning and hygiene authorities like ISSA point to damp, hard-to-clean surfaces as a driver of both slips and the spread of fungal infection in showers and locker rooms. A duckboard that keeps feet dry, grips when wet, and rinses clean is doing real health work, not just covering a floor.

Why a vinyl duckboard beats a wooden one, and why this one

The case for vinyl over timber comes down to what water does to each. Wood absorbs it — swelling, rotting, and harboring bacteria in every grain and joint. Heronrib is made from nonporous extruded PVC, so water can't soak in; it drains off and the surface dries. That single difference is why a vinyl duckboard stays hygienic for years where a wooden one slowly turns into a liability.

The open-grid construction does the duckboard's lifting job better than slats can. The extruded PVC sections raise the walking surface and let water fall through the grid and away, while the embossed top grips bare feet — and it's certified for it, earning the full A+B+C classification on the DIN 51097 barefoot ramp test, with a 0.6 dry / 0.5 wet reading on ASTM F1677. There are no gaps wide enough to catch a toe, and no loose boards to shift underfoot.

It also outlasts wood in the conditions that destroy it. On the maker's own scale it rates a perfect 100 for durability, resists UV without degrading (apart from the red), and works from below freezing to 140°F, indoors or out. And it's kinder underfoot than bare slats on concrete: it's rated for anti-fatigue comfort, giving a firmer, warmer, more forgiving surface to stand on barefoot.

Where it belongs — and what it isn't

Heronrib belongs anywhere a duckboard or slatted mat has traditionally done the job. That's communal and shared showers, changing rooms and locker rooms, the pool deck and its surround, and sauna, spa, and Jacuzzi areas. Built for heavy barefoot traffic and effective indoors or out, it suits a busy public leisure center as readily as a smaller club — or a home wet room or shower, where wood is a constant maintenance headache.

It's worth saying what this isn't. It's a walk-on duckboard surface, not a flotation device, and not the liner sheet that goes under an above-ground pool. If you want a mat to put under a pool or a float for the water, this isn't that product. Heronrib lays on top of your existing floor — tile, concrete, or decking — and turns it into a dry, gripped, barefoot-safe surface.

The other break from tradition is coverage. Where wooden duckboards are loose sections that leave gaps and shift around, Heronrib rolls out to cover a whole floor. It comes in rolls up to 40 feet long that cut to fit on site, so a full changing room or shower block becomes one continuous surface in long strips rather than a scatter of separate boards, and we can advise on finishing the exposed borders.

Three Things to Check Before You Spec It

Replacing wooden boards with a vinyl duckboard is straightforward once you've settled three things.

First, decide roll-out or sectional. To turn a whole changing room or shower block into one continuous dry surface, order the long rolls and run them wall to wall. If you only need to cover a bench area or a single shower bay, a cut section works like a drop-in duckboard. Measure the full barefoot area, not just the walkway, so there's no wet gap where someone steps off.

Second, confirm it's the barefoot-rated surface for your traffic. This carries the top A+B+C barefoot slip classification, which is exactly what a shower or changing room needs, and it's built for heavy barefoot traffic. It also holds up under shoes in poolside and staff areas, so knowing where bare feet and shod traffic mix helps you size the coverage and place any transitions.

Third, match the color to sun and setting. It comes in blue, gray, and red, with more colors available on request. For an outdoor deck in constant sun, choose blue or gray, since the red isn't UV-stable and will fade outdoors. Indoors, any color holds up — blue reads fresh by a pool, gray stays neutral in a locker room, and red can mark off a zone.

Frequently Asked Questions

How is a vinyl duckboard different from a traditional wooden one?

Answered by Dustin Thompson, Owner & CEO

It does the same core job — holding your feet up above the wet floor — but the way it's built solves everything wood gets wrong. Heronrib is an open grid of nonporous extruded PVC sections: the grid lifts the walking surface off the floor and lets water fall straight through and away, just like the gaps in a slatted board, while the embossed top grips bare feet. Because the vinyl doesn't absorb water, it won't swell, rot, splinter, or grow the fungus that wooden boards trap in their grain, and it carries anti-bacterial and anti-fungal additives on top of that.

Is it actually more hygienic and grippy than wooden boards?

Answered by Dustin Thompson, Owner & CEO

On both counts, yes. The nonporous PVC gives fungus and bacteria nowhere to live, and the anti-bacterial and anti-fungal additives actively resist them — a real difference from timber that soaks up water and harbors athlete's foot. For grip, it earns the full A+B+C barefoot classification on the DIN 51097 ramp test, with a 0.6 dry / 0.5 wet reading on ASTM F1677. It's also rated a perfect 100 for durability, handles UV (apart from the red), and works from below freezing to 140°F, so it stays sound where wood would rot or crack.

Can it cover a whole changing-room floor instead of loose boards?

Answered by Dustin Thompson, Owner & CEO

That's one of its biggest advantages over traditional duckboards. It comes in rolls up to 40 feet long, in 2-, 3-, and 4-foot widths, and cuts to fit on site — so instead of a scatter of loose boards with gaps between them, you can run long continuous strips across a whole room. For a small shower bay, a single cut section does it, and we can help finish the exposed borders so the edges look intentional and there's no lip to trip on.

Where would I use a vinyl duckboard?

Answered by Jinna Hopson, VP of Marketing

Anywhere you'd once have laid slatted boards to keep feet out of the water. The classic spots are communal showers, changing rooms, and locker rooms, plus pool decks and surrounds, saunas, spas, and Jacuzzi areas. Because it's built for heavy barefoot traffic and works indoors or out, it fits a busy public leisure center as easily as a smaller club — or a home wet room or shower, where wood is a constant maintenance headache. If it's a barefoot space that stays wet, a vinyl duckboard belongs there.

What does it feel like to walk on, and what colors can I get?

Answered by Jinna Hopson, VP of Marketing

It feels reassuringly solid and dry, which is the point. Instead of the cold, slick slap of wet tile or the give and splinters of old wood, you get a firm, cushioned surface with an embossed grip your feet can trust barefoot. It comes in blue, gray, and red, with more colors available on request — blue reads fresh and aquatic by a pool, gray stays neutral and hides grit in a locker room, and red can mark off a zone. Just keep the red to indoor or shaded spots, since it isn't UV-stable in constant sun.

How do I keep it clean in a busy shared shower?

Answered by Jinna Hopson, VP of Marketing

Easily, and that's a big part of why it beats wood in a communal space. Because it's nonporous and rolls up, you can hose or pressure-wash the surface, then lift a section to rinse and dry the floor underneath — no waterlogged boards, no slimy undersides. Regular cleaning keeps both the grip and the hygiene at their best. In a shared shower or changing room, that quick lift-and-rinse routine is what keeps the whole space feeling fresh rather than neglected.
