#67 Stone and Bulk Aggregates for Captain Cook, HI
Hawaii Rock Supply handles gravel and aggregate delivery in Captain Cook, HI, from bulk base course to washed stone. This is a thin-soil district, with bare young lava close to the surface through much of the Kona and Kau ground.
That ground changes how you build. A compacted base course layer is what carries a drive or a slab here, and how you move water away matters as much as what you put down.
Materials for Captain Cook Projects
Where a roof sheds onto ground that will not soak it up, drainage stops being an afterthought. Washed stone, French drains, drywells and downspout runs are how water leaves a Captain Cook lot, and the size of the stone you pick decides how well that works.
Start coarse. RipRap, sold locally as one man rock, is the hand-placeable size for gulch banks, culvert outlets and slope work where a Kona storm sends flash flow through dry channels.
Drain Rock, also called filter rock or lava rock, is the working stone for drywells, rock pits, French drains and downspout runs. Many subdivisions here have no street storm drain to tie into, so a drywell carries the water.
#67 Stone is a clean crushed size that suits pipe bedding, drainage and concrete aggregate, and it is one of the numbered sizes named in the state highway aggregate section.
Below that, 3/8" Crushed Stone, or chips, tops a compacted base, beds pipe and finishes paths. It is clean, so it passes water rather than holding it.
For the compacting layer under a drive, pad or slab, 3F Base Course is the material island yards and county books call base course: crushed basalt, and the layer that keeps a drive from washing into the gulch.

Ground and Conditions in Captain Cook
This side of the island works year round. Afternoon rain comes through the summer, and the winter Kona lows bring heavier spells, so timing a delivery around the wet stretch is worth a thought.
Across the Kona, Kohala, Waimea and Kau ground, rainfall swings from a dry coastal band to a genuinely wet belt a few miles uphill. The young lava underneath holds almost no water.
That is the practical point. Drainage here is about where surface flow goes, not how fast the ground takes it in.
A compacted base course layer under flatwork, plus drain rock at the low spots and a drywell where there is nowhere to discharge, is what keeps a site working through a Kona storm.
Wind-driven dust and sheet erosion are the other side of it. Bare leeward ground moves in the wind, and rip rap or a stone surface on exposed edges holds it in place.
