Slater Atlas Stone Lightening Insert

Lighten your atlas stone by adding a High Density Lightening Insert to the mix. We recommend planning to leave at least 4" of concrete on either side of the insert to reduce the risk of the stone breaking. We also recommend including Concrete Strengthening Fibers and a high strength concrete mix (Quikrete 5000, etc.) if adding a lightening insert to the stone. Instructions for installing Lightening Inserts are mentioned in the instruction sheet included with each order, or can be found here.
