Bulk Material Delivery in Larkspur, CA

Winter rain drives the work here, so gravel and aggregate delivery in Larkspur, CA starts with drainage. California Rock Supply stocks the washed stone that moves water, plus Class 2 base for everything built on top of it.

Clay soils in the Marin County hills hold that rain and swell. Sandy ground near the shoreline drains fast. Both need a plan before the first storm.

Materials for Larkspur Projects

Drainage stone comes first. Water has to leave the site before a driveway, patio or pad can hold up through a wet season. Start coarse and work down.

3/4" Drain Rock is the workhorse. It has no fines, so water passes straight through. Use it in French drains, drainage trenches and behind retaining walls.

Drain Rock handles drywells, downspout runs and the drainage layer under a slab. Clean stone, no dust, no packing.

RipRap armors what the water hits. Place it on slopes, creek banks and culvert outlets where winter runoff scours bare ground. Caltrans calls placed slope rock rock slope protection.

Move to base and surfacing. Class 2 Base, also called Class II base rock, is the standard California base under driveways, parking pads and pavers. It compacts hard and locks up.

Driveway Gravel tops a compacted base or refreshes an existing drive. Stone Screenings, or DG, packs firm for paths and patios laid over that same base.

Finer material finishes the job. Washed Sand beds and levels under slabs and pavers. Top Soil rebuilds planting beds over heavy clay.

Delivery to Larkspur and the Surrounding Area

Order online and set your own schedule. Pick the material, choose a quantity by the ton or the yard, and size the load with the calculator before you check out.

Then pick a delivery date at checkout. A dump truck arrives at your site and drops the load where you want it.

Coverage runs across Marin County. Along with Larkspur, trucks run to San Rafael, Novato, Mill Valley, San Anselmo and Corte Madera.

Have the drop spot clear before the truck arrives. Bulk stone and soil come off the bed in one pass, so the driver needs room to pull in and out.

Ground and Conditions in Larkspur

Time the work to the season. The dry stretch from late spring into fall is the window for base, driveway and paver work. Winter rain and saturated clay are what hold jobs up.

Soils change fast across this ground zone. Heavy clay in the Coast Range valleys and hills cracks when dry and swells when wet. Sandy dune and beach soils sit along parts of the shoreline and soak rain away quickly.

That difference decides your drainage. On clay, plan on clean washed stone and a place for the water to go. On sand, water already moves, so the base and compaction carry the job.

Schedule the delivery around the weather, not after it. A pad built on saturated clay will not compact, and it will not stay put.
