Hi all. I just finished a 70ft long retaining wall for a guy. Now i have to install steps for him. Its those interlock blocks that lean back and have a beveled edge. My question is. Should i get some Benderboard and make a form and pour a thin slab for this and then set the pavers down and do leveling sand inbetween? WOuld that be the best thing and if so how think the slab? It seemthats the easiest way to level it . and also this guy doesn't really take care of his back yard so i am guessing weeds will be inbetween the pavers in no time flat.
