Waterhog Classic Mats are the popular entrance mats in the industry. The raised square or "waffle" pattern superbly removes dirt and moisture. The surface of the Waterhog floor mats are constructed from an anti-static polypropylene material which will dry quickly and will not fade nor rot. WaterHog Inlay mats are created using a unique inlay process involving hand-cutting different pieces of material that are pieced together like a puzzle. 10 Colors Available.
