I've got roughly a 20' x 3' wall that needs to be put in to hold back some erroding dirt by a customers driveway. Nothing fancy at all. Really easy access, just about 1.5 yards of dirt for backfill, so its a pretty small job. ANyways, anyone know of a good place in the Richardson / Dallas area to get some blocks for walls? I was at HD tonight getting some paint for a friend and I looked at the regular-common wall blocks theyve got, although I couldn't get them to stack right, I couldnt figure it out, anyways... little help would be much appreciated.
