3/4 Minus, Stone and Soil Delivery in Harper, OR

Oregon Rock Supply handles gravel and aggregate delivery in Harper, OR, and 3/4 minus is the base most ground here starts from. It is crushed rock graded 3/4 inch down to fines, so it compacts and locks up under a driveway, a parking pad or a shop floor.

Harper sits in Malheur County, where the basins are closed and have nowhere to send water. That shapes what you put in the ground.

Water has nowhere to go in this part of the state, so drainage stone does real work here. Washed stone is screened free of fines, which leaves open voids that let water move through instead of sitting against a footing.

Drain Rock, also called 1 1/2 clean, is washed and open. It goes in French drains, curtain drains, footing drains, drywells and downspout runs.

3/4" Crushed Stone is angular rock with the fines screened out. Use it in drainage trenches, retaining wall backfill, construction entrances, and for bridging soft wet ground.

#57 Stone is a washed drainage stone for French drains, drywells and concrete aggregate. Most Oregon yards would call this size 3/4 clean.

For the compacting side of a job, 3/4 Minus is the standard Oregon base under driveways, parking pads, shop floors and shed bases. It keeps its fines, so it locks up rather than rolling underfoot.

1/4 Minus, or quarter minus, is the fines product. It beds pavers and flagstone, tops a compacted base, and fine grades paths.

Ground and Conditions in Harper

This is Basin and Range, Klamath and Owyhee Country ground: fault-block basins filled with lake-bed silt, alkali flats and playa ground, with basalt rims standing above them.

Across this part of the state, precipitation runs under 15 inches a year. The basins are closed and have nowhere to send water, so playa and alkali ground stays soft and holds surface water after snowmelt.

Wind moves across bare playa and alkali flats, and sheet flow comes off the rims into the basins during snowmelt and summer storms. That is the argument for a drainage layer under anything you build.

The working season is short, bounded by hard frost at both ends. Frozen ground and soft spring basins both stop compaction, so timing a delivery matters as much as the material.
