When designing stalls, what would work as a good subbase and base on the floor? Would making gravel (1½ to 2 inches) the subbase and stone dust for a base be a good pairing?

Stall flooring preferences vary with facilities. Below are some general recommendations for floor stalls: First, the barn site should be elevated several feet above the surrounding area with a suitable pad. This decreases incidence of water infiltration into stalls from surrounding runoff. Second, the subbase of the stalls must allow for drainage: eight to 12 inches of small rock (inch rock) is a suitable material. Above this subbase, place about one foot of clay to clay-loam type soil or packed screenings/stone dust. This base will provide percolation of urine to the subbase, yet should pack enough to provide a level floor. Mats and bedding should be placed above the soil base.
