Materials for Brisbane Projects

Decorative rock carries a lot of the work here. Beds, borders, dry creek beds and ground cover all start with the right stone, and the right stone starts with what sits under it.

For dry creek beds and swales, use Large River Rock. Big rounded cobble slows runoff and holds a channel in place. Pair it with River Cobble for borders, decorative beds and low-water landscaping.

For paths and patios, use Stone Screenings, or DG. It packs firm and fine, and it lays over a compacted base. For a looser walkable surface, Walkway Gravel works on garden paths.

Under all of it goes Class 2 Base, also called Class II base rock. It is the standard California base material, specified by Caltrans as Class 2 aggregate base. Recycled Class 2 base from Road Base or asphalt does the same job.

Where water needs to move, use Drain Rock in French drains, drywells and behind retaining walls. RipRap, also called rock slope protection, armors slopes and culvert outlets against storm runoff.

Ground and Conditions in Brisbane

Soils change over short distances in the Coast and Coast Ranges. Sandy dune and beach soils sit along parts of the shoreline. Heavy clay soils that crack when dry and swell when wet are extensive in the Coast Range valleys and hills.

That clay is what breaks an under-built base. Water sits on it, the subgrade softens, and the stone above moves. Build up grade with Fill Dirt first, then compact your Class 2 base in lifts over firm, drained ground.

Most rain falls from late fall to spring, much of it in a few large winter storms and atmospheric rivers. Sandy ground soaks it up fast. Clay and slopes shed it. Hillside runoff and slides on steep slopes, debris flows on recently burned ground, and wave erosion of sea cliffs all follow heavy rain.

The dry season from late spring into fall is the main window for base, driveway and paver work. Summer fog is common near the shore, but winter rain and saturated clay hold jobs up.

Order Class 2 Base and Decorative Rock in Brisbane

Start with Class 2 base, then layer your cobble, DG and drain rock over it. That order keeps a Brisbane bed, path or dry creek bed draining instead of heaving. Shop the materials online, size your load, and schedule delivery to your site.
