Gravel and Aggregate Delivery in Kilauea, HI
Gravel and aggregate delivery in Kilauea, HI runs year round, but the winter fronts set the schedule. Heavy rain along this coast turns bare ground soft, so grading and bed prep are easier to plan around a dry stretch.
Hawaii Rock Supply delivers base course, soil and stone to Kilauea and the rest of Kauai County.
The ground here decides what you need. Highly weathered clay holds water instead of shedding it, so a growing layer and a drainage layer both have to be built, not assumed.
Materials for Kilauea Projects
Grading and bed prep start with soil and fill. On ground that is a thin skin over lava or heavy clay, the growing layer has to be brought in and shaped before anything is planted.
Top Soil is screened soil for lawns and bed prep. It builds a growing layer where the native ground will not support one.
Garden Soil is a planting mix for raised beds, planters and new planting areas. It is often laid over a cinder layer so water can move down and away from roots.
Coral Fill is crushed coral limestone used as bulk fill to raise grade and as a sub-base under a base course layer. It is quarried inland caprock, and it is specified as subbase rather than as a base course material.
Under flatwork and drives, base course is the compacting layer. In Hawaii that means crushed basalt, and 3F Base Course is the material island yards and county public works specifications call for under slabs, shed pads and parking areas.
Where a drive or pad needs a binding, compacting stone, Crusher Run is sold by its nominal size, as 3/4 inch minus or 1-1/2 inch minus. 3/4 Blue Rock is clean crushed basalt at that size, used for drainage beds, drive surfacing and trench bottoms.
Sand and bedding layers finish the job. 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 washed with fresh water before it goes into concrete work, and it beds and levels under slabs.
Stone Screenings are basalt fines used as the bedding layer under pavers, flagstone and slabs, and for filling joints. Drain Rock is durable lava rock for drywells, rock pits and foundation drains.
For paths, beds and light drives, Cinder is an island material with no mainland equivalent. Black cinder is denser and takes traffic; red cinder is lighter and used decoratively.
Shredded Mulch holds moisture in beds and tree rings and keeps weeds down.
Ground and Conditions in Kilauea
This is the sharpest rainfall gradient in the islands. A few miles inland the ground takes far more rain than the coast does, and the leached clay underneath holds that water rather than shedding it.
So the ground stays soft long after the rain stops. That is why drainage stone earns its place under any slab or drive here, and why a compacting base course layer has to sit on ground that has been prepared rather than on wet clay.
Across the East and north Kauai side, the erosion drivers are river and gulch flooding, hillside slips on saturated clay, and wave and surge damage on the north shore through the winter swell season. Gulch and stream bank armoring takes RipRap, and one man rock is the island name for the hand-placeable sizes.
Work is year round. The winter months bring the heaviest fronts and the highest flood risk along the Hanalei and Wailua rivers, so exposed ground and open trenches are better finished before that window opens.

What stone should I use for drainage in Kilauea?
Drain Rock is durable lava rock for drywells, rock pits, French drains and downspout runs. That matters here because many subdivisions have no street storm drain to tie into, and the clay ground holds water.
3/4 Blue Rock and #67 Stone also work for drainage and pipe bedding.
