A truck bed fills with water every time it rains, and everything in it sits in that water until the sun finally dries it out. Tools rust, cardboard turns to mush, and loose gear slides around on a slick metal floor. A liner is supposed to fix this, but most liners make the water problem worse, not better.
Why a bed liner does not keep gear dry
A drop-in liner protects the bed surface but leaves your cargo lying in whatever water the bed collects, and it traps moisture underneath itself against the metal. A spray-in liner bonds a tough coating to the bed, but it is still a flat, sealed surface that water pools on. Either way, the gear is sitting in the puddle. The metal floor stays damp, hardware rusts, and nothing under the load gets any air.
Drain the bed and ventilate the load
The fix is to lift the cargo off the floor and let the water drain out the way the bed was designed to. That is what Dri-Dek truck bed drainage tiles do. Each tile carries 284 flexible legs per square foot that raise the load 9/16 of an inch off the bed floor. Rain and wash water drain through the open surface and out the bed's own drain points, while air circulates beneath the load so moisture never pools under your gear. The flexible legs also dampen the vibration that walks toolboxes and equipment around the bed on rough roads, though heavy cargo should still be tied down as usual.
Open pickup beds
Line the full bed or just the zone where tools and coolers ride. Gear stays high and dry, the bed drains underneath, and the liner lifts out whenever you need the bed for something else.
Truck tool boxes
A trimmed tile layer in the bottom of a crossover or side-mount box keeps hand tools above the condensation that starts the rust, and quiets the box on rough roads.
Service bodies and utility compartments
Service-truck compartments carry expensive equipment through wet conditions daily. Dri-Dek elevates and ventilates each compartment floor, resists the oils, grease, detergents, and brine of daily work, and has passed the UL 94V-O vertical flame test.
Built for the abuse a truck dishes out
A bed liner lives in sun, road salt, and temperature swings, so the material has to take it. Dri-Dek is made from Oxy-B1 vinyl with UV stabilizers, carries a tensile strength of 2750 PSI, is rated from -30°F to 167°F, and resists oils, grease, detergents, and brine. It trims to fit around wheel wells and tie-downs with a utility knife, snaps together with no hardware, and rolls up for a hose-off when the job is done, with no drilling or adhesive and no permanent change to the truck. More detail is on the material properties FAQ.

Cargo vans, trailers, and winter roads
The same drainage and ventilation logic applies to enclosed cargo floors that see wet gear, muddy boots, and pressure-wash cleanouts. A van or enclosed trailer floor holds moisture just like an open bed, and the elevated surface keeps cargo and the floor itself from staying damp between loads.
Winter is when a bed punishes gear hardest. Slush melts into salty brine and sits under everything until spring, and a flat liner just becomes a frozen puddle that traps the salt against your tools and the bed. The Oxy-B1 vinyl resists road salt and brine outright, stays flexible down to -30°F instead of going brittle in the cold, and keeps draining while the bed is wet. Roll it out at the first snow, let the season's slush drain through all winter, then hose it off in spring. The bed underneath never spends months soaking in salt, which is what rots through sheet metal and rusts every fastener in the box.
Common questions about water in a truck bed
How is this different from a drop-in or spray-in liner?
Liners protect the bed surface but leave cargo sitting in whatever water the bed collects. Dri-Dek elevates the cargo 9/16 of an inch, drains the water through, and ventilates beneath the load. It also removes without a trace, so nothing is drilled or bonded to the truck.
Will it handle summer heat in a black bed?
Yes. The vinyl is rated to 167°F and compounded with UV stabilizers, so direct sun in an open bed does not crack, curl, or fade it.
Does gear still slide on it?
The flexible legs damp the vibration that makes loads creep, which helps keep gear in place compared to a smooth bed floor. Heavy cargo should still be tied down as usual.
How do I clean it?
Roll the snapped-together liner up, hose it off or pressure wash it, rinse the bed, and roll it back in.
