Professional installers often include a deep layer of crushed gravel under permeable pavers to allow more runoff to soak through into the soil below. Many installations will include multiple layers of gravel, with coarser aggregate at the base and finer aggregate that sits on top of that bottom layer.

Some permeable paver designs include a water collection system set into the gravel layer to route runoff to a safe area for disposal.
