How many years will the memorial rocks last?
Due to modern high-performance polymers and other scientifically-developed, construction-grade admixtures, these GFRC cast stone replications are designed to last for generations–even in freeze-thaw conditions–and typically wear in the same manner as, or superior to, natural rock. The memorial rocks are actually one of the few products that will look better with age as the elements (i.e., rain, sun and snow) give them an even more lifelike, weathered appearance with each passing year.
