Hundreds of experiments over 14 months led Sonoma Cast Stone to reconfigure its mixes and modify its methods to create NuCrete, a trademarked precast-concrete surface that the manufacturer insists won't stain and will “look like new for years.” Cast concrete is said to be flexible enough to produce forms as varied as the square or rectangular RampSink or the WaveSink, a curvilinear style co-designed by Robert G. Zinkhan, AIA. Select from 20 standard colors or request a custom hue. Sonoma Cast Stone, 877.283.2400
