I just had my concrete driveway and footpath plus alfresco done and I noticed my builder only put the rubber foam around the base of the column at patio, while the rest of the house he drilled holes into the house's concrete slab and inserted steel rods into it and just tied the steel mesh to those....and I also didn't see him put "chairs" on the steel mesh as he and couple of workers just use hooks to pull up the mesh while the cement were poured.
So, I am now kind of worry if the house moves (as they surely will) will it cause a problem as the whole concrete footpath surrounding the house plus the driveway plus the alfresco which are now basically "locked-in" glued to the house??????!
