Our 85 year old brick house has a 8' x 10' porch that is 2 feet off of the ground in the back of the house (the porch was an addition). It is 2 layers of cinder block on the base and aabout 3inches of a concrete slab layered by flagstones on top.
Question: Do you think it is cinder block all the way through, or just a square of cinder blocks and a hollow middle????
I want to build a deck over it and was goinng to break up the 3 inch slab to allow for the decking and supports, but I'm wondering if I'm going to be dealing with ALL cinder block once I break up the top slab or have to work with cinder block and a section that is dirt in the center???/
