WaterHog mats are durable, stain-resistant mats with a unique bi-level design that traps dirt and moisture, keeping your floors clean, dry, and safe. The standard WaterHog mat features a classic waffle pattern. Bi-level surface effectively scrapes dirt and moisture from shoes, trapping it beneath shoe level to prevent tracking; water dam border holds moisture keeping it off your floors. WaterHog mats can hold up to 1-1/2 gallons of water per square yard. Reinforced rubber nubs prevent pile from crushing and extend the performance life of the mat. Solution-dyed PET fabric (24 ounces/square yard) is resistant to staining, dries quickly, and will not fade or rot. Beveled edges provide a safe transition from floor to mat; certified high-traction by the National Floor Safety Institute (NFSI). SBR rubber backing contains 20% post-consumer recycled rubber from car tires; PET surface is made from 100% post-consumer recycled plastic bottles.
