Weight
8-10 pounds per square foot.

Colors
Iron oxide pigments.  There are two steps to the coloring process.  Iron oxide pigments added to the cement before casting provide a body color which runs throughout each stone.  Accent colors may 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.

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 degrees F followed by a 12 hour thaw cycle at 70-75 degrees F.  Existing stone applications made from our exact processes have been in service for decades, showing superb performance in every way.
