Fill and Base Material Delivered in Ukiah, CA

California Rock Supply handles gravel and aggregate delivery in Ukiah, CA, and most orders here start with the ground. Coast Range valley soils run heavy clay, so a pad or drive often needs fill dirt first, then a compacted layer of Class 2 base on top. Get those two layers right and the surface material lasts.

Materials for Ukiah Projects

Building a pad means thinking in layers. Fill dirt raises grade and backfills until the subgrade is level and firm. Class 2 base, also called Class II base rock or Class 2 aggregate base, then goes on top at compacted depth. It is the standard California base, specified by Caltrans as Class 2 aggregate base.

Recycled base rock works the same way for drives and patios. Caltrans allows processed reclaimed asphalt and concrete in aggregate base, and some suppliers here call that material crushed miscellaneous base. For a drive that wants extra binding, crusher run is an option, though most Ukiah buyers still ask for Class 2 base for the same job.

For drainage, choose washed stone with no fines so water moves through: 3/4" Drain Rock for trenches and RipRap where a slope or culvert outlet needs armoring. On top, Top Soil and Shredded Mulch finish beds and tree rings.

Ground and Conditions in Ukiah

Soils here change over short distances. Sandy ground along parts of the shoreline drains fast, while heavy clay soils are extensive in the Coast Range valleys and hills. Clay cracks when dry and swells when wet, so it will not carry a load on its own.

That is the reason base depth matters more than base type. On clay you excavate deeper, bring in fill dirt to raise grade, and compact the Class 2 base in lifts at a minimum depth of 2 inches per lift. Skip that and the surface rutts within a season.

Most rain falls from late fall to spring, much of it in a few large winter storms and atmospheric rivers. It soaks into sandy ground quickly but sits on or runs off clay and slopes, which is where hillside runoff and winter slides start. Drainage stone and rip rap belong on those slopes before the rain arrives.

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 it is winter rain and saturated clay that hold jobs up.

Delivery to Ukiah and the Surrounding Area

Order online and pick your quantity by the ton or the cubic yard. Measure your length, width and depth, then convert to the unit the product page lists. If you are unsure, size the fill and base separately, since they compact at different rates.

Bulk delivery to a site in Ukiah means a truck that needs clear access and a firm spot to dump. Flag the drop point, keep overhead lines and soft ground in mind, and place fill and base where the machine can reach them. We also deliver across Mendocino County, including Fort Bragg, Willits, Redwood Valley, Covelo and Hopland.
