Can this be installed on an uneven concrete floor? We are converting our garage into a playroom. We want to find something that can hold up to heavy use from young kids but can also cover over the concrete which has some spalling and pitting.

Our 1" MMA Mats can be installed over floors that aren't perfect. As long as the cracks and pits aren't too large, these tiles will go over them with ease. If the cracks are pretty large, you run the risk of the tiles becoming damage due to use. In those instances, we would recommend repairing the concrete before installing our tiles.
