This is a sort of an odd job that we did during the slow winter months. The customer had ordered a green house to be installed and he wanted it to be professional, so he hired us to do the foundation for it. We excavated the ground, installed landscape fabric, poured a foundation, installed a stem wall made of pressure treated 4×12, and filled the area with river rock. He also had an electrician install electric and a plumber run water out there. The greenhouse was installed by Glasshut.com. Now he has a very solid greenhouse that should last a lifetime!
