I'm replacing a front porch platform, 26 feet 5 inches wide and extends 71 inches out from the wall of the house. I want to replace with a concrete platform 8 inches thick ( 4 1/4 yards total concrete ), but I'm not sure how to brace the form underneath to do that. The foundation around the three outer edges of the current platform is cinder block, with a wall of cinder block through the center, approx. 5 feet high. Since the current platform is wood, there is no foundation for the inner edge against the wall of the house. The support along the inner edge underneath is simply nailed to the wood base of the house sitting directly on top of the foundation. Instead of building a foundation wall for the inner edge of the platform against the house, would using 4x4 lumber as bracing material for the form underneath that inner edge and everywhere else provide enough support for an 8 inch pour?

Don't do it with concrete that way. I'm in the middle of tearing out a concrete porch that rebar into the foundation didn't hold up. It sagged next to the house and rocked the entire block foundation back. 8" is way too thick anyway, 4" is enough if you have to do it. But, without a solid foundation around all 4 sides(including along the house wall) it will sag and crack. After getting this porch out, which replaced a wood porch, I am going back in with a wood deck/porch with concrete piers for the roof supports.

Also leaving any wood under the concrete is good eating and an invitation for termites.
