First: more compacting of the 1.5in stone Second: the drainage pipe we put at the bottom of the excavation. This pipe is about 6" above the bottom of the sub-base. It is an over flow pipe. It is pvc and has holes on the top of the pipe and is solid on the bottom so water will flow out of it if it can not be ex-filtrated through the soil. The picture only shows the extension piece that it is not perforated. Third: Screeding the 3/4in stone Fourth: screeding the 3/8in beading layer stone Fifth: laying the pavers. And look at that! String line is being used, wait... make that three!!!!
