We have a 4'x4' cement slab coming out of the back of our garage. We need to add one or two steps to it. Is there any way to attach cement steps to this slab? We could build the forms and pour the cement ourselves, but would they attach to the slab? Also would like to put some pavers on top of the slab but have been told that fastening them to the cement slab with cement wouldn't work the best. Would they attach with masonry epoxy? Any help would be appreciated.
