I'm doing extention on my house. The extention will be a two story frame construction. I alredy have done the footing (12"x24" at 4' deep). I had hard time pouring the concrete in the back of the house. Had to use expensive pumping equipment. Inspector gave me OK to change the stemwall from proposed solid concrete to 8"x8"x16" cinder blocks.
Can you tell me how to go on?
Thank you in advance for your help.
