When an Illinois homeowner plans a patio over slow prairie clay, overlooking drainage can leave moisture at the hardscape during northern freeze-thaw conditions. #8 Crushed Stone is clean crushed material with few fines, creating open spaces for drain details instead of forming a soil-like layer. It also works as a small aggregate in concrete mixes. That open texture can be helpful where clay holds water near a finished surface.
For a patio installation, use #8 Crushed Stone in the area below pavers or between units identified by the design, rather than blending it into the clay. Keeping it in that assigned location preserves its intended function. This approach is especially useful where Illinois ground remains wet through seasonal weather changes and a hardscape needs a clear drainage path.
