Heronrib Matting

What Heronrib does before a wet pool deck takes someone's feet out

A poolside or locker-room floor seems harmless until someone crosses it barefoot and the water underfoot decides the rest. It's tempting to trust textured tile or a fast mop. But on a flat surface, water spreads into a thin film right where bare feet land, and tile that grips when dry turns slick the moment it's wet.

Heronrib is built to clear that film. Its two-layer body sits on channelled underbars that self-drain in four directions, so water runs off and away instead of pooling on top. The embossed surface gives bare feet a firm grip. That's what makes it a true non-slip pool mat rather than one that only feels safe dry.

On a barefoot wet floor, a slip isn't minor. The National Floor Safety Institute links wet, hard floors to a large share of slip-and-fall injuries, and pools, showers, and changing rooms keep those floors wet from open to close. A mat that drains water away and holds grip underfoot is doing safety work every hour it's down.

Why a self-draining PVC build, and why this one

Heronrib is made from strong, non-porous PVC, and non-porous is the word that matters in a barefoot wet area. Because water can't soak in, the mat doesn't stay damp or harbor the bacteria and fungus that thrive on wet floors. On top of that, it's built with anti-microbial and anti-fungal properties, so it actively resists the athlete's foot fungus and mildew that locker rooms and showers tend to grow.

The two-layer construction is what makes the drainage work. Channelled underbars lift the walking surface off the floor and send water away in four directions, while the embossed top holds traction. That grip is certified — Classification C on the DIN 51097 barefoot ramp test, and a 0.9 dry / 0.7 wet reading on ASTM F1677 — strong figures for a surface people cross with no shoes on.

It's also made to last in tough conditions. The PVC resists most acids, alkalines, and oils, stands up to UV without degrading, and works from below freezing up to 140°F, so an outdoor deck and an indoor shower are both fair game. The two-layer body adds cushioning and sound absorption underfoot, so a busy pool hall is a little softer and quieter to walk through.

Where it belongs — and what it isn't

Heronrib earns its place wherever bare feet meet a wet floor. That's the pool deck and pool surround, but also changing rooms, locker rooms, shower rooms, spa and sauna areas, and the wet zones of gyms and recreation centers. Because it works indoors or out and contours to uneven surfaces, it suits both a tiled shower floor and a textured outdoor deck.

It's worth being clear about what this mat is not. It's a walk-on barefoot surface, not a flotation device, and not the liner-protector sheet that goes under an above-ground pool. If you're after a mat to put under a pool or a float for the water, this isn't that product. Heronrib works on top of the deck, under your feet — on concrete, tile, or a finished pool surround.

For larger areas it behaves like a system. Rolls join edge-to-edge with connector clips or welded snap track to cover a whole pool hall seamlessly, ramped edging finishes the borders so there's no trip lip, and floor hooks anchor sections where they need to stay put. The same mat scales from a single shower bay to a wall-to-wall deck.

Three Things to Check Before You Spec It

Heronrib is easy to order well once you've settled three things.

First, plan the layout and joins. For a single shower or changing bay, one cut piece does it. For a full deck or pool hall, rolls join side-to-side and end-to-end with connector clips or welded snap track, so map where the seams fall and where you'll want ramped edging to finish an exposed border cleanly.

Second, measure the whole wet path, not just the obvious spot. The walk from the pool to the showers, the full changing-room floor, the lip around a spa — size the mat to cover wherever feet are actually wet, because a dry-foot gap is exactly where the next slip happens. It cuts to fit on site, so odd shapes and obstacles aren't a problem.

Third, plan for heat and movement outdoors. The PVC handles sun and a wide temperature range, but like any thermoplastic it can shrink slightly — up to about 2%, faster in heat — so on a hot, exposed deck, anchor sections with floor hooks and leave a little room at fixed edges rather than butting it tight wall to wall.

Why Mats Inc.

We've been matching mats to real floors since 1964, and barefoot wet areas are where the wrong choice gets noticed fastest — by feet, by inspectors, and by anyone who slips. We'll help you size Heronrib to your actual wet path, plan the seams and edging for a clean install, and choose the right anchoring for an outdoor deck. It's part of our wider lineup of pool and wet-area matting, and every order is backed by our 1-year limited warranty.

Frequently Asked Questions

What's Heronrib made of, and how does it drain so well?

Answered by Dustin Thompson, Owner & CEO

It's made from strong, non-porous PVC in a two-layer build. The top layer carries an embossed surface that grips bare feet; underneath, a set of channelled underbars lifts that surface off the floor and lets water run away in four directions. So instead of sitting in a puddle, water clears the moment it lands. The non-porous PVC won't soak up moisture, and it's built with anti-microbial and anti-fungal properties, so the same mat that drains also resists the bacteria and fungus wet floors tend to breed.

How slip-resistant is it for bare feet, and will it last outdoors?

Answered by Dustin Thompson, Owner & CEO

Its grip is certified for barefoot use specifically — Classification C on the DIN 51097 ramp test, with a 0.9 dry / 0.7 wet reading on ASTM F1677, both strong for a no-shoes surface. As for lasting outdoors, the PVC resists UV without degrading, shrugs off most acids, alkalines, and oils, and works from below freezing up to 140°F. That combination is why the same mat holds up on a sun-exposed deck and in a daily-use shower room without going brittle or slick.

What sizes does it come in, and can it cover a big area?

Answered by Dustin Thompson, Owner & CEO

It comes in 33-foot rolls in 2-, 3-, and 4-foot widths, and you cut it to fit on site. For a large pool hall or deck, rolls join side-to-side and end-to-end with connector clips or welded snap track, so there's no practical limit to the area you can cover in one continuous, seamless surface. For a small space like a shower bay, a single cut piece does the job. Custom matting is available when a standard width won't fit the layout.

Besides right at the pool, where does Heronrib make sense?

Answered by Jinna Hopson, VP of Marketing

Anywhere people go barefoot on a wet floor. It's a natural fit for changing rooms, locker rooms, and shower rooms, the surrounds of spas and saunas, and the wet zones of gyms and recreation centers — not just the pool deck itself. Because it works indoors or outdoors and contours to uneven ground, it's as comfortable on a textured outdoor deck as on a tiled indoor floor. If a space mixes bare feet, water, and foot traffic, it belongs there.

What does it look and feel like underfoot?

Answered by Jinna Hopson, VP of Marketing

It has a clean, ribbed, embossed surface that reads as purposeful — clearly there to grip and drain rather than to decorate. The look is low-key and functional, the kind of surface that signals the floor is handled without drawing attention to itself. Underfoot, the two-layer body adds a bit of cushioning and even absorbs sound, so a busy, echoey pool hall feels a touch warmer and quieter to cross. If a specific color or finish matters for your space, let us know and we'll confirm what's available.

My pool area is an odd shape with drains and corners — will it fit?

Answered by Jinna Hopson, VP of Marketing

Almost certainly. Because it cuts to fit on site and contours to uneven surfaces, you can shape a run around drains, ladders, corners, and changing benches instead of forcing the space to match a fixed mat. Ramped edging finishes any exposed border so there's no trip lip, and for a tricky footprint custom matting is available. Send us the dimensions and the obstacles, and we'll map out a layout that covers the wet path cleanly.
