WaterHog® Diamond (Classic) mats are durable, stain-resistant mats with a unique bi-level design that traps dirt and moisture, keeping your floors clean, dry, and safe. Rather than the traditional “squares” pattern, these mats feature an attractive diamond pattern. WaterHog mats can hold up to 1.5 gallons of water per square yard, keeping it off your floors. Reinforced rubber nubs prevent pile from crushing and extend the performance life of the mat. The surface is PET, an eco-friendly polyester made from at least 90% recycled plastic and is resistant to staining, dries quickly, and will not fade or rot. WaterHog Diamond mats are proudly made in the USA, and certified high-traction by the National Floor Safety Institute. This mat features a classic rubber border. Please note, mat sizes are approximate as rubber shrinks and expands in conjunction with temperature and time. Tolerable manufacturing size variance is 3-5%.
