Mason Sand for Patios in Kurtistown, HI

Planning gravel and aggregate delivery in Kurtistown, HI around the weather is the practical first step. Rain is heavy in any month here, and the ground rarely dries out the way it does elsewhere.

Hawaii Rock Supply delivers bulk material across Hawaii County, with base course and bedding sand sized to your project and ordered online.

Ground and Conditions in Kurtistown

Across the Hilo, Puna and the Hamakua coast region, soils run from very shallow organic ground over pahoehoe and aa lava to deep volcanic ash. Rock and clinker sit close to the surface wherever the flows are young.

On a thin base, that shows up fast: the surface shifts underfoot, water pools in low spots, and a paved edge starts to move.

This is the wettest built-up ground in the state. Rainfall runs from around 60 inches a year near the coast to over 200 inches on the upper slopes.

It falls on lava that either swallows water into cracks and tubes or sheds it in seconds where the rock is sealed.

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

Gulch and stream scour, undercutting along sea cliffs, and fast runoff over lava and thin ash soils are the erosion patterns to plan around.

Work runs all year. The rain is heavy in any month, and the winter fronts and Kona lows are heavier still, so timing a delivery matters more than waiting for a dry spell.

Materials for Kurtistown Projects

Bedding under pavers and flatwork is where a patio or walkway is won or lost. Screenings and mason sand are the two bedding layers island crews ask for by name, and both are crushed basalt products rather than beach sand.

Stone Screenings, also called fines or quarry fines, are the standard bedding layer under island flatwork. They bed pavers and flagstone and fill the joints between them.

Basalt screenings pack tight and hold a level surface.

Mason Sand is manufactured from crushed basalt or blended with calcareous sand. It goes into block and brick work, mortar, paver joints and play areas.

Buyers who want sand under a slab want Washed Sand instead, which is washed with fresh water before it goes into concrete work.

Base course is the compacting layer under all of it, and in Hawaii it means crushed basalt. Island yards and county public works specifications call it base course, or 3/4 inch minus base course, and it goes under driveways, parking pads, slab bases and shed bases.

Untreated base is the same material under another name.

Two supporting materials round out a patio or flatwork job. 3/4 Blue Rock is clean crushed basalt at that size, used for drainage beds, drive surfacing and trench bottoms.

#67 Stone covers pipe bedding, crushed rock cradles and concrete aggregate, and no. 67 is one of the few numbered sizes named directly in the state highway aggregate section.

Delivery to Kurtistown and the Surrounding Area

Quantities are ordered by the ton or by the yard. Each product page has a calculator, so you can size the load before you check out.

Pick a delivery date at checkout and a dump truck tips the material on site in one pile.

Kurtistown sits in Hawaii County, and delivery covers the island, including Hilo, Captain Cook, Mountain View, Holualoa and Honokaa. Because the rain here is heavy in any month, a load left in the open starts to settle and pack, so plan the pour or the bedding work close to the delivery date.

Order online and the truck arrives. That is the whole process.

Questions About Gravel and Bedding Material

What gravel is best for a driveway in Kurtistown?

Base course is the compacting layer island drives are built on, and in Hawaii it is crushed basalt, sold as 3/4 inch minus. It handles the wet ground and the lava substrate better than a clean stone because the fines bind it together.

For surfacing over a compacted layer, look at driveway gravel or 3/4 blue rock.

How much material will my project need?

That depends on the area you are covering and the depth you want, and both are yours to set. Quantities are ordered by the ton or the yard.

Each product page has a calculator so you can size the load from your own numbers before you order.
