I have a set of concrete stairs, 4 steps, that I want to widen. My question is does anything have to be done to where new concrete meets existing concrete, or should I just drill into it and extend rebar into new form ?
Also, I intend on topping new and old stairs with pavers. The old stairs are not quite level and true, can I built them up level with new stairs with the "thinset"? That I intend to use to set the pavers ?
