How we make it

Concrete is a moldable medium

Each project requires uniquely crafted molding and supportive processes. We use many materials for molding concrete. Some projects start with old-fashioned templates translated to melamine while others, for example, may come from a custom rubber mold using the technology of CNC machines. We also utilize 3D printing technology in some of our molding. We are engineers after all, and, are constantly looking for new ways to improve the process and create unique offerings.

From the beginning, RockMill works with architects, designers and home-owners to curate the design vision. We work with each customer through the entire decision making process from picking the product that is right for them, refining their desires for color, shape and feel to the delivery of a hand-crafted, one-of-a-kind piece. All the skill, creativity and ingenuity that goes into every project is part of what makes our products so special.

At RockMill, we thoroughly enjoy every step of the creation of a piece. We relish in the process, the crafting of the details and LOVE that every piece is its own.

Popular Questions and Concerns

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.

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.

Although durable, both concrete and natural stone are “brittle” materials, as opposed to “elastic” materials. Sharp edges are more susceptible to chipping than rounded edges. Use care with pots and pans around edges.

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.

Concrete has its own unique look as compared to other surfaces. With time, the sealer can show subtle wear marks, light scratches, minor chips, blemishes, etcThe nature of concrete lends itself to a product that already has subtle variation in color and texture which results in wear marks blending in well. We actually love the character that everyday wear gives a piece! If a particular spot is a nuisance, a 3M green pad may be used to blend the area. Try to test this in an inconspicuous spot to understand the effect. Essentially you will be micro scratching the area and modifying the sheen.
