Atlas™ structural brick is a hollow clay brick product that was developed to permit the use of reinforcing to enhance the structural characteristics of brick. Brick is an excellent product to resist compression loads, but often masonry is required to act as a beam or wall to resist earthquake, wind or gravity loads. Reinforcing steel placed in the brick cells is grouted to create resistance to tension. Atlas brick are designed similar to Concrete block but with allowable design stresses 2 to 3 times stronger.
