Recycled rubber floors are a superior material when trying to reduce noise, contain vibration, and absorb shock from workout equipment. This product is specifically manufactured for durability and is designed for either residential or commercial applications that are exposed to heavy foot traffic. This rubber mat can be used as a workout mat, flooring for home gym, patio mats, as a garage mat, flooring in basement game rooms, or even livestock trailer flooring.

One of the biggest concerns commonly associated with rubber matting is the installation. This mat weighs roughly 50lbs. in a 4ft x 10ft roll and generally stays down under its own weight; therefore there is no for permanent adhesives. In order to keep the edges and entry points from being a trip hazard, double-sided carpet tape can be used for a uniform and level installation. Recycled Rolled Rubber Mat matting is available in 8 different lengths allowing you to dimensionally match almost any room to help create a safe and warm environment to inhabit.
