Ground and Conditions in Pleasanton

Pleasanton sits in the Coast Range valleys, where heavy clay soils are extensive. That clay cracks when dry and swells when wet, and it is the reason a thin base fails under a patio.

When the base under pavers is too shallow, the clay moves with the seasons. Pavers heave, joints open, and the surface rocks underfoot. The fix is a properly compacted base layer, not a thicker sand bed.

Most rain arrives from late fall to spring, often in a few large winter storms. On clay, that water sits on top or runs off instead of soaking in. A drainage layer and correct grading keep the base from turning soft.

The dry season from late spring into fall is the main window for base, paver and flatwork jobs. Winter rain and saturated clay are what hold work up, so plan the base and bedding stages for dry ground.

Materials for Pleasanton Projects

Patio and flatwork jobs start with the bedding and base layers. Class 2 base, also called Class II base rock, is specified by Caltrans as Class 2 aggregate base and is what most Pleasanton patios and driveways go down on. It compacts firm and carries the load under pavers, slabs and Stone Screenings paths. Order it through Class 2 Base.

Recycled base rock, or CMB, is Class 2 base made from Road Base or asphalt. Caltrans allows processed reclaimed asphalt and concrete in aggregate base, and it works the same way under drives, patios and slabs.

For the bedding layer itself, washed sand levels and beds the pavers and sits under slabs. Mason sand is the choice for brick and block work and for filling paver joints. Both are graded fine and pack flat.

Stone Screenings, or DG, is a fine, firm-packing path and patio surface laid over a compacted base. It suits low-water landscape ground cover and garden paths that need a walkable finish.

Clean stone handles water. Drain rock and 3/4 inch drain rock carry no fines, so water moves through them in French drains, drywells and drainage behind retaining walls.
