Romeros Granite installs Quartz countertops that are sealed and therefore not porous, they are primarily made of quartz, which means they are more durable than granite. Quartz is also scratch and chip-resistant, since its polymers and resins give it a little more flexibility than natural stone. However, unlike granite, the resin in engineered counters is not heat resistant, so you can't take your pans from the stove to the countertop like you can with granite.
