Concrete is a fascinating material; what you see is not what you get. It requires a lot of pre-visualization but offers a great opportunity for invention. The results are rather permanent, so “measure twice, pour once” is a huge understatement of the care and audacity required in the creative concrete process.
This job was scary – Jay Griffith had called for black concrete with a retarded cure to be washed down the next day for a soft sand finish. A truckload of black goo was pumped in to produce what looked like a fancy oil spill. But at the end of the second day’s work, the surface had settled into a delicious soft gray that looked just like a sugary licorice gumdrop.
