Buy Blue Rock in Hauula, HI
Hawaii Rock Supply handles gravel and aggregate delivery in Hauula, HI. The ground on this side of Oahu is wet through the winter, so timing a drop matters as much as the material itself.
Base course is the compacting layer under drives and pads here. It is crushed basalt, and it goes down over ground that is rarely fully dry.
Materials for Hauula Projects
Base course is the starting point for a drive, a parking pad, or a slab base in Hauula. Island yards and county public works books call the compacting layer base course, and in Hawaii it means crushed basalt.
You may also see it listed as 3/4 inch minus base course or untreated base.
3F Base Course is the material for that layer. It binds under compaction and carries the flatwork above it.
For a drive or pad that needs a binding, compacting material, Crusher Run is sold by nominal size, as 3/4 inch minus or 1-1/2 inch minus. Driveway Gravel surfaces an existing drive or tops a compacted base course layer.
Clean crushed basalt at 3/4 inch is blue rock on this island. 3/4 Blue Rock goes into drainage beds, drive surfacing, trench bottoms and construction entrances.
At 3/8 inch, 3/8" Crushed Stone is chips, used as a topping over compacted base, for pipe bedding and for paths.
Cinder is an island material with no mainland equivalent. Black cinder is denser and takes traffic; red cinder is lighter and used decoratively.
Cinder suits paths, garden beds and light drives.
Screenings are the standard bedding layer under island flatwork. Stone Screenings bed pavers, flagstone and slabs, and fill the joints between them.
Sand comes in two forms here. Mason Sand is manufactured from crushed basalt or blended with calcareous sand, and it goes into block work, mortar and paver joints.
Washed Sand is bedding and leveling sand under slabs.
For growing ground, Top Soil builds a lawn or bed layer where the ground is a thin skin over lava or heavy clay. Garden Soil fills raised beds and planters, often over a cinder layer for drainage.
Shredded Mulch holds moisture in beds and keeps weeds down.
Ground and Conditions in Hauula
The trades hit the Koolau wall and drop their water almost daily. The crest sees well past 100 inches a year, and the lower slopes are far wetter than the leeward side of the same island.
That water has to go somewhere. The clay below drains slowly, and low ground near the water table sits close to it.
A base course layer here needs to stay above ground that is rarely fully dry.
Across the Windward Oahu and the North Shore, the soils run from deeply weathered clay on the Koolau slopes to sandier coastal ground. Steep stream and gulch scour off the Koolau, hillside slips on saturated clay, and shoreline erosion all move material.
Work runs year round, but the softest ground falls between October and April. Heavy runoff comes off the pali after any stalled front, so a drive or pad built in that window needs its base course in place before the ground takes more water.
Drainage matters as much as the base. Drain Rock fills drywells, rock pits, French drains and downspout runs, and island filter stone is durable lava rock.
Many subdivisions here have no street storm drain to tie into, so a drywell does the work instead.
