RockMill builds customized concrete countertops and sinks for homes and businesses in Rhode Island, Massachusetts, Connecticut, New York and across the United States. We are a small studio, just three people, so work closely with you to create that sink or counter of your dreams. Each piece we create expresses your unique tastes and interests and is unlike any other.

About Us

RockMill Countertops was founded by Alyre MacLure and Chris Murray. Alyre and Chris are both mechanical engineers who met while working in the composite manufacturing and design industry for a multinational cooperation. It is with their background of creating and continually optimizing and improving processes that they developed cutting-edge technology to create affordable and unique custom surfaces. In 2014, they decided to take the leap, break out from their 9-to-5 jobs, and start a concrete countertop business. Combining their creative energy, knowledge of technical production processes, and their love of concrete, RockMill Countertops was born. RockMill is based on the idea that concrete countertops can be both affordable and extraordinary- allowing for full expression of individual tastes and styles.

How often do I need to reseal?

We offer different sealer systems depending on the application and the customers taste. Most customers opt for a high performance factory-applied sealer that does not require periodic resealing. Simple maintenance is all that’s required to keep your countertop looking good.

How durable is concrete?

General food preparation will not stain the concrete as long as the sealer is maintained. The sealer is intended to keep the food away from the concrete itself. Spills should be removed as soon as possible; however, the resistance to oils, acids, alcohol and normal food items is excellent. If visiting the shop, ask to see our stain panel, it’s quite impressive!
Please use cutting boards as cutting on the surface can scratch and damage the sealer (not to mention your knives!). Scratches in the sealer could occur if heavy, rough or sharp objects are dragged across the countertop surface.

As with almost all types of countertop surfaces, please use trivets. Our sealers are tested with high heat 350 – 450F (depending on type) and show no signs of damage but we do encourage you to use a trivet.
