One of our recent kitchen remodels required concrete countertops and the design was such that they needed to be built in place. The countertops needed to be less than 2 inches thick and integrated backsplashes needed to be about an inch thick. There was a want for caps on two areas that the owner wanted darker, almost black with the rest to be grey and just a bit darker than your basic sidewalk. We added black and white granite to expose in the countertops. I promised the owner that the tops would crack, (because it is concrete) and so far, I have not kept that promise. There were 4 counters and 2 bartops and with several corners and penatrations, I was expecting at least some cracks. Pouring these counters in place and grinding and polishing is not an easy process. After completing this project I have some new ideas for some other tops and even some walls, in place with various finishes.
