Mason Sand for Patios in San Andreas, CA

Gravel and aggregate delivery in San Andreas, CA runs best from late spring into fall. Winter storms turn clay and steep drives to mud. California Rock Supply delivers bulk material across Calaveras County, and orders placed before the rain starts keep a project on schedule. If you are bedding pavers, the base under them matters as much as the stone you see.

Good flatwork starts with Class 2 base, the standard California base material, then a leveling layer of mason sand on top.

Ground and Conditions in San Andreas

A thin base is what fails first around here. Rocky hillside soils sit shallow over bedrock in many spots, and clay pockets hold winter water while Stone Screenings drains fast. A patio bed that is too shallow shifts, heaves and rocks as the ground moves under it.

The fix is a compacted Class 2 base worked into the native soil, plus a drainage path so runoff from slopes above has somewhere to go. Heavy winter rain runs off quickly over shallow soil and bedrock, and water that pools under a slab will find the edge.

Plan the work for the dry months. Winter storms turn clay and steep drives to mud, and higher towns can see snow delays in mid-winter.

Materials for San Andreas Projects

Patios and flatwork drive most orders. Pavers, flagstone and slabs all need a base that compacts firm, then a thin bedding layer that levels true. Here is how the materials sort out.

• Class 2 Base, also called Class II base rock: the compacted base under pavers, slabs and Stone Screenings paths. Caltrans specifies it as Class 2 aggregate base.
• Mason Sand, also called masonry sand: the bedding layer under pavers and block, and the sand swept into paver joints.
• Washed Sand, also called concrete sand: leveling and bedding under slabs, and a coarser option for laying pavers.
• Washed Sand: a coarse sand and fine gravel blend for leveling and bedding.
• Stone Screenings, also called DG: paths and patios that need a fine, firm-packing surface over a compacted base.

For drainage around a patio, use clean stone with no fines. Drain Rock and 3/4" Drain Rock both work in French drains and behind retaining walls, and water moves through them instead of sitting against the base.
