Mason Sand for Patios in Farmington, CA

Gravel and aggregate delivery in Farmington, CA runs on the dry season. The long, hot stretch from late spring into fall is your working window, and winter rain that leaves clay soft and sticky is what stops jobs. California Rock Supply stocks Class 2 base, sand, stone and soil for delivery here.

Farmington sits on deep valley alluvium in San Joaquin County, and that ground shapes every flatwork job you plan. Build the layers right and the patio stays flat through the wet months.

Ground and Conditions in Farmington

The ground under Farmington is deep valley alluvium. Much of it is heavy clay that cracks in summer, and parts of the valley have a cemented hardpan a few feet down.

That hardpan stops water moving deeper. On flat clay ground, winter storm rain has nowhere to go, so it ponds. A patio built straight onto native soil will hold that water under the slab.

Thin bedding layers are what fail first. A paver patio set on sand alone, with no compacted base under it, shifts and dips once the clay below it swells and dries. The edges drop and the joints open.

The fix is layering. Compacted Class 2 base carries the load, a bedding sand levels the pavers on top, and drainage gives the water a path out. Caltrans specifies this base material as Class 2 aggregate base.

Materials for Farmington Projects

For patios and flatwork, the layers matter more than any single material. Start with Class 2 base, also called Class II base rock or class 2 aggregate base. It is the standard California base material, and it goes under pavers, slabs and Stone Screenings paths.

Recycled base rock is Class 2 base made from Road Base or asphalt. It does the same job under drives, patios and slabs. Some suppliers here also sell crushed miscellaneous base, or CMB, for the same subgrade work.

Above the base, the bedding and surface layers change with the job.

• Mason Sand for paver joints and bedding under brick and block work.
• Washed Sand for leveling and bedding under slabs and pavers.
• Stone Screenings, or DG, for paths and patios that pack firm.
• Walkway Gravel for garden paths that need a finer, walkable surface.
• Driveway Gravel for topping a compacted Class 2 base on an existing drive.

Drainage belongs in the plan from the start. Drain Rock and 3/4" Drain Rock are clean stone with no fines, so water moves through them. Use them in French drains, drywells and behind retaining walls.
