I've been asked to provide an estimate for a flat rock wall. The customer showed me the style of rock she would like. It is basically about 3" high and comes in various shapes and is almost white in color. Not sure what the technical name for the rock is. Anyway, the wall is 45' long and averages about 18" high. I spoke with a local block company and they gave me a price of $200 per pallet. A pallet covers about 20' with a 1' high wall. Does that price seem in the ballpark or should I do some more shopping? I've done quite a bit of paver installs, but never a flat rock wall. Any good sites for install techniques? I am assuming I need a 3" base of compacted QP to make a nice sturdy, flat base. As far as estimating time I see 2 people 10 hours each. Does that seem about right? Thanks for any advice. I will post the pictures when it is complete.
