Drain Rock and Bulk Aggregates for Makawao, HI

Hawaii Rock Supply brings gravel and aggregate delivery in Makawao, HI, and drainage stone does the heavy lifting on this side of the island. Trade-wind rain runs down the windward flank of Haleakala, and the ash soils above Makawao hold that water and stay soft under load.

So the ground here is rarely dry, and water has to have somewhere to go. Base course, drain rock and washed stone handle most of that work.

Materials for Makawao Projects

Start with the open, washed sizes. Water moves through them instead of sitting in them, which is what a French drain, a drywell or a downspout run needs.

Many subdivisions here have no street storm drain to tie into, so a rock pit in the yard does the work.

Coarse washed stone goes in first. Drain Rock is the island filter and drainage stone, durable lava rock for drywells, rock pits, French drains and foundation drains.

#4 Crushed Stone is the heavy end for trench bottoms on soft or wet ground.

Then the mid sizes. #67 Stone beds pipes and crushed rock cradles, and it drains.

#57 Stone fills drywells and works as concrete aggregate. Island yards often ask for these by inch size rather than by the number.

Blue rock is the clean 3/4 inch crushed basalt. Use 3/4 Blue Rock for drainage beds, drive surfacing, trench bottoms and construction entrances.

3/8" Crushed Stone, sold here as chips, tops a compacted layer, beds pipe and finishes paths.

Fines-bearing material is a different job. 3F Base Course is the compacting layer under drives, parking pads and slab bases, and in Hawaii it means crushed basalt.

Stone Screenings bed pavers, flagstone and slabs and fill the joints.

A dump truck tips the load on site in one pile. That is the whole of it, so plan where you want that pile to land before the truck arrives.

Hawaii Rock Supply delivers across Makawao and the rest of Maui County, including Kahului, Kihei, Wailuku, Lahaina and Kula.

Ground and Conditions in Makawao

Ground here stays softest from October through April, and the windward side is wet in any month. Time a delivery around that if you can.

Material tipped onto saturated ash soil is harder to work than the same load on a drier day.

The soils on the Haleakala slopes are volcanic ash and ash-derived. Ash holds water and stays soft under load, so bedding and base layers have to cope with ground that is rarely dry.

Gulches cut through that ground and carry runoff away fast, which is why bank armoring matters on steeper ground.

Erosion shows up as slips on saturated ash slopes and sheet erosion across cleared pasture. RipRap, the hand-placeable one man rock, armors gulch banks and culvert outlets.

For a drive, Driveway Gravel surfaces an existing drive or tops a compacted base course layer.
