Hello, The front porch of my house has cracking/separation between the concrete slab and the bricks beneath it. The porch is about 4'x10'. The separation can be seen in the pictures attached. It only occurs in the front right corner. The concrete feels sturdy except when I jump on the front edge, above the area where the cracking is. I am trying to determine what if any repairs are needed. I am wondering if a footer would typically be placed under the concrete slab thus the bricks would be mainly for aesthetics. I am going to place a new step in the area where the previous owner "repaired" the porch. I am wondering if I could just fill these cracks in or if I should pull the bricks out and rebuild up to the bottom of the concrete slab. Or would these repairs just be temporary fixes and the ideal fix would be to replace the whole slab? Thank You IMG_1536 | Flickr - Photo Sharing! IMG_1540 | Flickr - Photo Sharing!
