Materials delivered in Hawaii County
Base course is crushed basalt graded to a maximum nominal size.
Order it for driveways, parking pads, slab and shed bases. It is the layer that carries flatwork and keeps a drive from washing into the gulch.
Blue rock, chips and drain rock cover most drainage work. Screenings bed flatwork, and topsoil builds a growing layer where the ground is shallow.
Choosing the right material
Match the material to the job. A compacting layer under flatwork takes base course.
A drainage run takes clean stone that lets water move.
- Base course and crusher run for drives, pads and slab bases.
- Blue rock and drain rock for drywells, rock pits and French drains.
- Chips and screenings for bedding, paths and paver joints.
- Cinder for paths, beds and light drives.
- Topsoil and garden soil for lawns and planting areas.
Fines-bearing material compacts. Clean open stone drains.
Keep the two apart and the layer does its job.
Ground conditions across Hawaii County
This county spans more than one ground region. In Hilo, Puna and the Hamakua coast, soils are very shallow over pahoehoe and aa lava, with deep volcanic ash along the coast.
In Kona, Kohala, Waimea and Kau, thin soil and bare young lava cover much of the ground. Cinder and ash soils sit on the Hualalai and Kohala slopes.
Rainfall splits the same way. Puna runs from around 60 inches a year near the coast to over 200 inches on the upper slopes, falling on lava that swallows water or sheds it.
Kona swings from the driest coastal band in the state to a wet coffee belt a few miles uphill, over young lava that holds almost no water.
That is why drywells and rock pits do the work a street storm drain does elsewhere. A compacted base course layer keeps a drive from washing into the gulch.
Erosion follows the same pattern. Hamakua sees gulch and stream scour and undercutting along the sea cliffs, plus fast runoff over lava and thin ash soils.
On the leeward side, wind drives dust and sheet erosion across bare lava and pasture. Kona storms send flash flow down dry gulches.
Work runs all year in both regions. Rain is heavy in any month on the windward side, and winter fronts and Kona lows are heavier still.
