WaterHog Diamond mats are durable, stain-resistant mats with a unique bi-level design that traps dirt and moisture below foot level, keeping your floors clean, dry, and safe. The surface is made with solution-dyed polypropylene that dissipates water for quick drying and will not fade or rot. WaterHog mats are backed with SBR rubber which contains 20% post-consumer recycled rubber from car tires. The rubber will not crack or curl, ensuring your mat will lie flat and remain in place. The Diamond pattern featured on this mat is the standard, WaterHog Diamond design with a rubber border (sometimes referred to as a "classic" border).
