View Full Version : Typical base?

What is the typical base material used for walls and pavers, regular driveway gravel (#8's?)? On walls, can (or should?) a 1" or so sand leveling pad be used under the base course?

And my next baffling question.... WHERE do you go to get plans engineered? What dictates engineering, and who typically mandates and regulates this stuff?
