Ground and Conditions in Harvard
The ground here is deep windblown loess over Columbia River basalt, with silt loam on top that seals when it rains. Across the Palouse hills and the Clearwater and Snake canyons that seal sheds water instead of taking it in.
Long slopes push runoff onto drives and yards, and water perches where the loess meets the basalt below. A patio set on thin, loose ground shows it fast: soft spots, rocking slabs, joints that open up.
The fix is a base that carries the load and a drainage layer that gives perched water somewhere to go. Sheet and rill erosion on cropped loess slopes in this part of the state runs heavy, so anything you leave exposed moves.
Sticky loess mud through the wet months is the real constraint on hauling and compaction. Work goes best from late spring through fall, and winters here bring repeated freeze and thaw.
Frost depth is left to the local jurisdiction, so the building official sets the figure for a footing.
Materials for Harvard Projects
Under pavers and flatwork, the base course does the work. Road mix, also called 3/4 road mix or 3/4 minus, is crushed base with the fines left in so it locks up under a roller.
It is the same load whether you call it road mix, road base or 3/4 minus.
On public works plans in Idaho, base is called out as crushed aggregate by type rather than by a class number.
Above a compacted base, 3/8 Chip is the bedding and topping material. The chips are angular, so unlike Natural Pea Gravel they knit together and stay where they are put.
For a softer surface, 3/8" Natural Pea Gravel suits patios and walkways. It is round and uncrushed, so it rolls underfoot where chips do not.
Where flatwork needs a fine, even bed, Mason Sand sets brick, block and paver joints. Washed Sand handles bedding under pavers and slabs and concrete work.
Fines from crushing, sold as Stone Screenings or chat, bed flagstone and fill paver joints. For a low spot that has to come up before any base goes on, Fill Dirt brings grade up first.
