I am planning on building a raised concrete patio. I would like to build the perimeter of block and fill it with stone and then cap it in concrete to be finished with blue stone later. The patio will be about 3 ft off the ground and jogs in and out but basically 40 ft long and about 12 ft wide.
I plan to hook #2 re bar into the top of the block and fill the blocks with concrete. Is the stone fill enough support for the concrete ? If not how far can I span it before I need another block wall for support.
I built a home once that had a 10 ft x 10 ft sun room filled with stone from the basement footings to the main floor and capped in concrete. It seemed to work well. Does anyone see a problem with this?
