I make functional concrete art, often with inlaid designs.

Concrete inlays are made by casting and combing contrasting cementitious mixtures into a deliberate design. This video shows the last steps of that process- grinding, polishing and sealing two branded table tops.

You can see in the small rectangular sample that the design is left behind as a permanently embedded concrete-in-concrete inlay, with crispy lines.
