While it's always a joy to watch the magic Chris can do on his own, it's also a treat to see what a well coordinated team can do, working together.I was impressed. The explanation about how they kept it all in alignment and the groundwater wrap was interesting and informative too.Seeing those concrete pipes reminds me that years ago I went on a service call to a company up where I live that made concrete pipes. It was an interesting machine. Also the groove on the small end with the gasket was cut after the pipe was casted and dried. That cutter was the machine I was called out on. Cool to see pipe like this being pieced together.
