Cambria surfaces are durable, stronger than granite, and nonporous––making it as safe as stainless steel for food preparation. They are NSF 51 certified for both food and splash zones. Stronger than granite, Cambria is pure natural quartz. It is durable and more resistant to surface damage than other stone. Cambria comes with a Lifetime Limited Warranty. Cambria is also green. During processing, 100 percent of the water used in Cambria’s plant and fabrication facilities is recycled through a series of advanced settling and filtering techniques.
