Mason Sand for Patios in Sunnyvale, CA

California Rock Supply handles gravel and aggregate delivery in Sunnyvale, CA for two kinds of buyers: contractors setting pavers and flatwork all season, and homeowners rebuilding one patio or driveway. Both usually start with Class 2 base, the standard California base material. Clay soils in the Santa Clara Valley ground move with the seasons, so the bedding under a patio matters as much as the pavers.

Materials for Sunnyvale Projects

A paver patio or concrete slab fails from the bottom up. The bedding layer and the compacted base under it decide whether the surface stays flat or rocks and settles after a few wet winters.

Start with Class 2 Base, also called Class II base rock or Class 2 aggregate base. Caltrans specifies it as Class 2 aggregate base, and it is the compacted structural layer under pavers, slabs and Stone Screenings paths. Recycled Class 2 base, made from Road Base or asphalt, does the same job where a recycled material fits the spec.

For the bedding layer itself, Mason Sand is the usual choice. It screeds flat and even at an inch, so pavers seat without lipping. Washed Sand works for leveling and bedding under slabs, and Washed Sand is a coarser blend for the same work.

Around the edges of the flatwork, Stone Screenings, or DG, packs firm for paths, patios and low-water ground cover laid over a compacted base. Walkway Gravel gives paths a finer, walkable surface than loose crushed rock.

Ground and Conditions in Sunnyvale

The most common call we get is a patio or driveway that has settled, cracked or gone uneven. A thin base is almost always the cause. Local soils change over short distances, so sandy ground and heavy clay can sit on the same block.

Clay shrinks and cracks in the dry season, then swells when the winter storms arrive. Sand drains fast. A base that is too thin over either one moves, and so does everything on top of it.

The fix is depth and compaction. Excavate enough for a compacted Class 2 base under the bedding sand, then compact it in lifts. The dry season from late spring into fall is the main window for this work. Winter rain and saturated clay are what hold jobs up.

If a retaining wall or a low spot is part of the plan, put clean stone behind it. 3/4" Drain Rock and Drain Rock have no fines, so water moves through instead of pushing on the wall. On sloped ground, RipRap armors banks and culvert outlets against winter runoff.

Delivery to Sunnyvale and the Surrounding Area

Order online and pick the material and the quantity. Bulk aggregate is sold by the ton or by the cubic yard, and the two are not the same number. A yard of damp sand weighs more than a yard of dry drain rock.

If you know the square footage and the depth, the material calculator converts that into tons or yards for you. For a patio, figure the compacted base, the bedding sand and any edge material separately, then add a little for waste.

We deliver bulk loads to jobs in Sunnyvale and across Santa Clara County, including San Jose, Santa Clara, Mountain View, Milpitas and Palo Alto. Tell us where the truck can back in and where you want the pile dropped, and we will place it close to the work.

Questions from Sunnyvale Buyers

What gravel is best for a driveway in Sunnyvale?

Start with Class 2 base, compacted in lifts, for the structural layer. Top it with Driveway Gravel if you want a finished surface, or leave the base exposed if the drive only needs a firm, binding material. On clay ground, get the base depth right first, because a thin base is what makes a drive rut and pothole.

How much material will my project need?

Measure the area and decide the depth, then let the calculator convert square footage into tons or yards. A compacted base loses volume once it is rolled, so order for the finished depth rather than the loose pile. For a patio, add the base, the bedding sand and any drainage stone as separate line items.

Get Your Sunnyvale Patio Material Sized Right

Run your patio or driveway dimensions through the material calculator, and it will turn square footage and depth into tons or yards you can order directly. If you are unsure whether your ground calls for extra base depth, tell us what you are seeing and we will point you to the right material. Start your order online when you are ready.
