There are a lot of fallacies as it is refers to Pet Turf in the artificial grass industry. Be careful about artificial turf companies that offer a knit or flow through backing for Pet Turfs. The backing on these turfs are missing one of the most important characteristics of a good synthetic grass and that is a stable backing. The backing that sits on the compacted crushed rock has be extremely stable and strong. The artificial turf grasses that don't have a polyurethane backing probably aren't worth the money. They will not stand the test of time in the elements installed in the ground. Trust me we learned the hard way. Call Global Syn Turf today.
