Heavy duty crawler tractor.
In the rocky areas of Sacramento County, large excavators are a necessity.
This pool is nearly 13 feet deep and takes a thicker bar and more dense pattern.
This pool is nearly 10 feet deep and of a simple design.
Due to expected weather issues, this pool received a skim coat of gunite to prevent errosion during construction.
Take a look at the size of those pipes. The larger ones are 4-inch pipes. They will pump over 300 gallons per minute to the waterfall (each).
Combined with the reinforcing steel, the gunite provides the structural integrity of the pool. The gunite is shot at high velocity to provide the maximum compaction (and density).
The plaster is applied by a large crew. As soon as they finish the last detail the pool is filled.
