Fill and Base Material Delivered in Keaau, HI

Hawaii Rock Supply handles gravel and aggregate delivery in Keaau, HI, and the ground here decides what you order. Across the Hilo, Puna and the Hamakua coast side, soil is often a thin skin over pahoehoe and aa lava, with clinker and rock close to the surface wherever the flows are young.

Under-building a base course layer is easy when you cannot see what is underneath. Fill and sub-base go in first to raise grade and build the pad, then base course goes on top as the compacting layer.

A dump truck tips the material on site in one pile. Bulk delivery reaches Keaau and the rest of Hawaii County, including Hilo, Kurtistown and Mountain View.

Materials for Keaau Projects

Raising grade and building pads is where most Keaau work starts, because the lava surface underneath leaves little room for a level build. Coral fill is the sub-base for that job, and it is quarried inland caprock rather than anything taken from the shoreline.

Once the pad is up, base course is the compacting layer under drives, parking pads and slab bases. Island yards and county public works specifications both call it base course, and in Hawaii it is crushed basalt.

For a driveway, base course goes down first and Driveway Gravel surfaces over it. Long rural drives on the outer islands usually need both layers rather than surfacing alone.

For a patio or walkway, Stone Screenings bed the pavers, and 3/8" Crushed Stone covers the joints and paths.

For drainage, Drain Rock fills drywells and rock pits, and 3/4 Blue Rock handles trench bottoms and construction entrances.

Ground and Conditions in Keaau

This is the wettest built-up ground in the state. Rain falls on lava that either swallows water into cracks and tubes or sheds it in seconds where the rock is sealed, with almost nothing in between.

That is why drywells and rock pits do the work here that a street storm drain does elsewhere. Many subdivisions have no street storm drain to tie into at all.

Where the ground is thin over lava, an under-built base course layer will not hold up. Coral fill raises the pad and gives base course something to compact against, which matters more here than on deep soil.

Runoff over lava and thin ash soils is fast, and gulch and stream scour adds to it. A pad that sits low will take water from every direction.

Work runs all year, and the rain is heavy in any month. Winter fronts and Kona lows are simply heavier still, so a drainage layer is worth planning for on any job.

What is the best base under pavers in Keaau?

Start with a base course layer compacted over the pad, then bed the pavers in stone screenings. Base course is the crushed basalt layer local specifications call for under flatwork, and screenings are the standard bedding under island flatwork.

Where the ground is shallow over lava, coral fill goes in first to raise grade so the base course has something to sit on.
