Hoping a few of you may have some different ideas, suggestions, estimates for putting together a concrete stackable stone wall. We will be installing 68' of base course row and a total of 172 face ft of wall. I have figured on using 12" wide and 6" tall stackable concrete wall block. This gives us roughly 344 blocks needed. The price of the stones is not critical as I will price them locally but we could use some input on the time it might take to build these walls and what you would charge for this service. Topsoil for backfill has been provided by the home contractor and is reletively close to the wall location so we will probably backfill by means of wheelbarrow rather than larger equipment. Thanks!
