This structure was built in 2010.

In this video we are sharing the finished structure after doing all that is listed below.

Prior, we've applied spray foam on the entire structure and a 23" layer of shotcrete. Then a grid of rebar which will have 6" of shotcrete sprayed.

After that, an additional layer of rebar is installed and shotcrete. The total thickness of concrete is 1 foot thick everywhere.

Do not attempt to build this type of structure without proper engineering and professional assistance. There are dozens of little things that are extremely important to do to ensure they are built safely and properly.
