You may need to reinforce your floors for quartz countertops, depending on the size and thickness of the quartz and your floor. Quartz weighs between 20-25 pounds per square foot, which means it’s very heavy. A professional engineer can tell you if your floors need reinforcing.
Quartz countertops are increasingly popular because of their durability, looks, low maintenance, amongst other reasons.
Quartz is a natural hard crystal material, which is grounded and then mixed with other materials to create slabs good enough to be used in the home. Because of how durable and hard and dense quartz can be, quartz countertops are heavy.
A quartz countertop can be up to three inches thick and generally weigh between 20-25 pounds per square foot. This is heavier than even granite and requires proper structural support sturdy enough to handle quartz countertops.
Because of all this weight, installing a quartz countertop is a job for professional installers. Because quartz countertops are so heavy, it may require you to have your floor reinforced, depending on various factors, such as floor material and the size of the floor joists. The size and structure of the countertops you’re choosing will make a difference, too.
Small, less complicated jobs in small kitchens or bathrooms are different jobs than larger, more complicated ones with quartz slabs that are thicker and longer.
We recommend having a professional engineer visit the site where you’d like to install a quartz countertop so they can assess the structure of the area.
Good, reputable professionals will be able to tell you if the quartz countertops you’re choosing will require you to reinforce the floors and provide you with recommendations for what to choose if this is so.
