Hello:
This countertop is a hand trowelled concrete done by a firm in Martinez, CA called Concrete Interiors. Although the process looks simple, to get this look requires patience and skill to avoid a DIY-looking result. The material is custom-colored, then poured into a mold where it goes through several stages, the most important of which is the hand trowelling that creates this interesting finish. Suggest you contact Terry and get a quote...not do it yourself!
Good Luck, Pat
