We are looking to build a retaining wall to level up a section of our sloping back yard, to make a usable space. This is a pic of what we want, using stamped and stained concrete. Has anyone here had anything like this done? Looking for a reputable concrete company to come give us a bid to do a retaining wall, back fill, top soil and sod. Also pour a sidewalk at the same time. We've had a hard time just getting anyone to come give us a bid.
