CRS High Density Gym Flooring

CRS High-impact rubber parts are designed to be tough and durable. They can be installed without adhesive meaning they don’t need any extra help from glue. We overbuild these components for maximum durability!

The difference between CRS and everyone else.

With a weight of 107 lbs, the CRS 9″x12″x24″ block is one of the heaviest blocks that you can buy. This makes it less likely to move around if hit by force. CRS Blocks are unique because of the process they are built. Competitor’s products are usually grind and glue, but the CRS process is different and creates strong, durable blocks that won’t break apart in use.

The competitor’s block is the result of a process that grinds together rubber particles and holds them together with a glue binder. It’s porous, as you can tell by its rough texture from all those tiny pits in it! The problem with this particular method is that high-impact falls might break or crack through to your floors below because it wasn’t really meant for something so tough.

The comparison between grind and glue blocks and CRS blocks.
