my husband cemented cinderblocks down in a step pattern, then we used slab like rocks, im not sure of there exact name, but they are flat kinda tan looking. just started putting together them as he went, after he got it built we smoothed the sides with cement and covered the sides and the top bowl with small river rock to match the walkway, he inserted plumbing pipe from the filter going into top bowl, and another pipe 3rd shelf down for more water flow
