Include our large-poly, super-strong polypropylene/polyethylene blended synthetic macro-fibers in your concrete mix to assure the strongest possible stone. These fibers act like mini re-bar, successfully replacing steel fibers, welded wire mesh, and conventional reinforcing bars in the stone. Fibers increase overall durability, fatigue resistance, and flexural toughness of the stone. Bulk mixture includes (1) 12oz bulk bag or box of fibers, equivalent to around 8 small bags of fibers.
Small Bag - Include with wet concrete mix:
8"-12" Stone: 1/2 Bag
14"-18" Stone: 1 Bag
20"-24" Stone: 2 Bags
Bulk Box - Include with wet concrete mix:
8"-12" Stone: Small Handful
14"-18" Stone: Large Handful
20"-24" Stone: Two Large Handfuls
Concrete Mixing Bag
The Reusable Concrete Mixing Bag eliminates the need for a concrete mixer or wheelbarrow.
Empty a 40, 60, or 80lb bag of concrete into the mixing bag, add water, twist the bag closed, and shake. Once you are done using, lay the bag flat and let dry overnight. The next day, empty the dried concrete contents into a trashcan - clean-up is that easy!
We love this bag, and often prefer using this over our concrete mixer!
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.
