Mason Sand for Patios in San Dimas, CA

Order gravel and aggregate delivery in San Dimas, CA without leaving your truck. California Rock Supply sells bulk material online by the ton or the yard, then hauls it to your site. Start with Class 2 base, the standard California base under pavers, slabs and driveways.

This is the Southern California coastal plains and inland valleys ground zone. Soils run from sandy loam to clay, and expansive clay shows up in many basins and hills.

Ground and Conditions in San Dimas

A paver patio fails in a thin base, not in the pavers. Too little base and the sand bedding migrates, edges settle, and joints open within a season.

Expansive clay drives that. It swells when wet and shrinks and cracks when dry, so a slab sitting on it moves. Winter storms and atmospheric rivers drop a season of rain in a few events, and runoff sheets off hard dry ground fast.

Fix it with depth and compaction. Put down a compacted Class 2 base, then bed the pavers in mason sand. Build the base thicker than you think you need, and compact in lifts, not one deep pass.

The long, warm, dry season suits base and paver work for most of the year. Winter storm days are the main interruption, so plan around them.

Materials for San Dimas Projects

Bedding and base are different jobs, and each needs the right material. Here is what fits a patio, walkway or drive in San Dimas.

Class 2 Base, also called Class II base rock or Class 2 aggregate base, is the structural layer. Caltrans specifies it as Class 2 aggregate base, and it goes under pavers, slabs, Stone Screenings paths and parking pads. Compact it and pavers have something to sit on.

Mason Sand, also called masonry sand, is the bedding layer. It levels under pavers, fills joints, and spreads firm so the surface stays flat. It also handles brick and block work.

Stone Screenings, or DG, is the fine path and patio surface. Lay it over a compacted base and it packs firm. Washed Sand, also called concrete sand, beds and levels under slabs.

For drainage beside the patio, use Drain Rock, clean stone with no fines so water moves through. 3/4" Drain Rock fits French drains and drainage trenches. River Cobble and Large River Rock handle dry creek beds and borders where runoff needs slowing.
