We need to run about 160ft of conduit along a steel picket fence in an asphalt parking lot. It is in an industrial type location so surface mounted is ok, not going to trench and bury it. I think my two options are attach EMT directly to the fence, or run GRC on roof blocks across the ground. At first I thought to run GRC directly on the ground but that would create a dam for runoff and cause water to pool.
Anyone have any better ideas? What will I need as far as expansion joints?
