Stone Mill, Inc.
Manufactured Stone
Weight
Stone weighs 8-10 pounds per square foot.
Durability
Manufactured stone made with our process has a compressive strength well in excess of 4000 psi. Freeze-thaw testing by certified independent test labs showed no visual damage or change in the material after 30 days of alternate freezing for 12 hours at 0-5 °F followed by thawing for 12 hours at 70-75 °F. Existing stone applications manufactured from our exact processes have been in service for decades, showing superb performance in every way.
Thickness
Stone thickness varies from 3/4 to 2 1/2 inches; average thickness is 1 1/2 inches.
Colors
Iron oxide pigments added to the cement before casting provide a body color which runs throughout each stone. Accent colors may also be added to each stone by brushing a special mixture containing iron oxide colors to the molds before casting, producing a permanent "face color". Existing applications have shown no undesirable color change after many years of weathering.
