This super-tough mat will protect floors from mud and grime and holds 1.5 gallons of water per square yard. The reinforced waffle pattern withstands heavy foot traffic and the "water dam" border helps to trap moisture. It's constructed with polypropylene fibers, features rubber backing to guarantee that it lays flat, and it is UV resistant, allowing for years of outdoor use. Easy to clean - simply vacuum, hose off or steam clean!
