I'm looking into building an olympic platform... The construction will be 3/4" plywood and then 3/4" Premium Extreme Mats on top of the plywood... I want to know if the PEM will take the punishment of dropping bumper plates on to them?

Our 3/4" Premium Extreme Mats were designed for this purpose. These revulcanized mats are our most durable mats and will provide your subfloor with ample protection from the dropping of heavy weight. These mats are very shock absorbent and are very easy to clean and maintain and can be installed as full flooring or used as a stand-alone mat.
