Dri-Dek Interlocking Tiles

What Dri-Dek does before standing water turns a floor slick and moldy

In a shower, sauna, locker room, or pool deck, water doesn't just make the floor slick — it sits. A flat surface, even a textured one, holds a film of water right where bare feet land, and the warm, damp film that lingers between uses is exactly what mold, mildew, and germs feed on. Mopping buys you a few minutes; the water comes back.

Dri-Dek solves it from a different angle: it lifts you above the water. Each tile is a raised, knobby, perforated grid, so water drains straight through and flows away underneath while you stand on the dry high points on top. Air circulates in the gap below, so the floor actually dries between uses instead of staying wet. You get grip up top and a floor that isn't a permanent puddle.

That combination matters in barefoot wet areas. Hygiene and cleaning authorities like ISSA stress that standing water and damp, hard-to-dry floors are what drive both slip risk and microbial growth in showers and locker rooms. A surface that keeps feet up out of the water and lets the floor beneath dry is tackling the slip and the mold problem at the same time.

Why an interlocking raised-vinyl build, and why this one

Dri-Dek is molded from a tough, UV-stabilized virgin vinyl in a flame- and chemical-resistant formulation, which is what lets it live on a wet floor for years. It resists the inorganic acids, oils, grease, detergents, and brine that wet areas and cleaning routines throw at it, holds up from -30°F to 167°F, and carries UV stabilizers so outdoor sun doesn't break it down. The same material is made to resist mold, mildew, and bacteria rather than harbor them.

The design is the other half. Each 12-by-12-inch tile is 9/16 inch thick with a knobby, perforated top, so it drains in every direction and cushions underfoot at the same time — the flex in the raised knobs takes some of the ache out of standing on hard concrete or tile. It's also flame resistant, having passed the UL 94V-0 vertical flame test, and it's tough, with a tensile strength around 2,750 PSI.

Best of all, it goes down without a contractor. The tiles, sheets, and rolls snap together on all four sides to build a surface of any size or shape, and they trim with a knife to fit wall-to-wall or around a drain, a bench, or a corner. Beveled edge and corner pieces finish the exposed borders into gentle ramps. When it's time to clean, you hose it, pressure-wash it, or lift a section and rinse under it.

Where it belongs — and what it isn't

Dri-Dek is at home anywhere a floor gets wet and stays wet. That's pool decks and pool surrounds, showers, saunas, steam and changing rooms, locker rooms, and the damp ring around a spa or hot tub. Because it interlocks into any shape and handles sun and temperature swings, it works indoors and out, in commercial facilities and in a home bathroom, basement, or patio alike.

It helps to be clear about what this isn't. It's a walk-on modular floor 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. Dri-Dek installs on top of your existing floor — concrete, tile, or decking — and turns it into a dry, draining surface.

One honest note on chemistry: the vinyl resists most acids, oils, and solvents, but a few aggressive industrial solvents are the exception, so for a specialized chemical environment it's worth checking the specifics with us. In a normal pool, shower, or locker-room setting, chlorine, cleaning products, and daily wear are well within what it's built to take.

Three Things to Check Before You Spec It

Dri-Dek is simple to order once you've settled three things.

First, choose your format. Loose 1-by-1-foot tiles are the most flexible for a small or intricate space and for lifting individually to clean. Pre-assembled 3-by-4-foot sheets or 3-by-12-foot rolls cover a big pool deck or locker room far faster, snapping to each other just like the tiles. Many jobs mix them: rolls for the open floor, loose tiles to fill the edges.

Second, plan your edges. Wherever the surface meets open floor that people step onto, the beveled edge strips and corner pieces turn the 9/16-inch height into a gentle ramp, so there's no lip to trip on and carts or wheelchairs can roll on. Decide which sides are exposed before you order so you have the right trim on hand.

Third, pick a color with the room in mind. It comes in twelve colors, so you can go practical or design-led. Pool Blue and Blue lean fresh and aquatic on a deck; gray, black, and almond read neutral and hide grit in a locker room; brighter colors can zone an area or match a brand. Darker, muted tones show debris the least between cleanings.

Frequently Asked Questions

How does Dri-Dek keep you out of the water, exactly?

Answered by Dustin Thompson, Owner & CEO

It works by lifting you above the floor instead of just draining the top. Each tile is a raised grid of knobs with a perforated, open surface, so water falls straight through and flows away underneath while your feet rest on the dry high points. The gap beneath lets air move and the floor dry between uses, which is what stops the standing water and the mold and mildew that come with it. It's molded from a tough, UV-stabilized vinyl in a flame- and chemical-resistant formulation built to live in that wet environment.

Will it hold up to chlorine, sun, and years of wet use?

Answered by Dustin Thompson, Owner & CEO

It's built for exactly that. The vinyl resists inorganic acids, oils, grease, detergents, and the brine and chlorine of a pool environment, and it's UV-stabilized so sun doesn't make it brittle — in weatherometer testing it held around 98 to 99 percent of its tensile strength and color. It works continuously from -30°F to 167°F, so an outdoor deck through summer and winter is no problem, and it passed the UL 94V-0 vertical flame test. A couple of aggressive industrial solvents are the exception, so for a specialized chemical setting, check with us first.

How do the tiles, sheets, and rolls differ, and which should I get?

Answered by Dustin Thompson, Owner & CEO

They're the same surface in three formats, and they all interlock with each other. Loose 1-by-1-foot tiles are the most flexible — best for small or intricate spaces and for lifting one at a time to clean under. The 3-by-4-foot sheets and 3-by-12-foot rolls are pre-assembled tiles that cover a big pool deck or locker room much faster. Most large jobs mix them: rolls or sheets for the open floor, loose tiles to fill in edges and odd corners.

Where does Dri-Dek work best?

Answered by Jinna Hopson, VP of Marketing

Anywhere a floor gets wet and stays wet, indoors or out. It's a natural on pool decks and surrounds, in showers, saunas, steam and changing rooms, and locker rooms, and around the damp base of a spa or hot tub. Because it snaps into any shape and handles sun and temperature swings, it's just as at home in a commercial aquatic center as in a home bathroom, basement, mudroom, or patio. If the floor gets wet, it has a place there.

What colors does it come in, and how should I choose?

Answered by Jinna Hopson, VP of Marketing

It comes in twelve colors, which is part of what makes it easy to fit a space rather than fight it. Pool Blue and Blue feel fresh and aquatic on a deck or around a spa; gray, black, and almond read neutral and professional in a locker room and hide grit well; and the brighter colors — red, yellow, teal, green — can zone an area or pick up a facility's branding. If you want the floor to disappear and stay looking clean between washes, the darker, muted tones show the least debris.

My space is an odd shape — can I make it fit, and even design a pattern?

Answered by Jinna Hopson, VP of Marketing

Yes, and that's one of the best things about it. Because every piece interlocks on all sides and trims with a knife, you can build a surface to any footprint — around a drain, a bench, a curved pool edge — and finish the exposed sides with beveled edge and corner pieces for a clean, ramped border. And since it comes in twelve colors, you can mix them to create borders, lanes, or a simple pattern, or match a brand color. Send us your layout and we'll help you plan the pieces and colors.
