Perfect for most applications inside or out, Waterhog Mat's unique design makes it revolutionary. The raised rubber "water dam" border traps dirt and water - keeping them off carpet and floors, providing a slip resistant surface and minimizing floor damage. The rubber reinforced face nubs and waffle or diamond design proved crush proof scraping action. Carpet is made of primium 24 oz/yd2 anti-static polypropylene fiber system that dries quickly and won't fade or rot. When wet, the rubber reinforced surface allows water to be wicked to the bottom of the mat away from foot traffic. Green friendly rubber backing has 20% recycled rubber content and is available in smooth or cleated types. Anit-static. Easy to Clean: Just vacuum or hose off and hang to dry. Recommended for computer rooms, around electronic equipment, malls, banks, hotels, offices, restaurants, healthcare, supermarkets and more. Certified slip-resistant by the National Floor Safety Institute.
