Crushed Stone, Sand and Gravel in Mountain View, CA

California Rock Supply stocks gravel and aggregate delivery in Mountain View, CA for driveways, pads, drainage and planting work. Class 2 base leads the lineup, alongside crushed rock, drain rock, sand, topsoil and decorative stone. Soils here change over short distances, so the right pick depends on what your ground does when it gets wet.

Materials for Mountain View Projects

Most jobs around Mountain View start with the base. Class 2 base, also called Class II base or Class 2 aggregate base, is the standard California base material, specified by Caltrans as Class 2 aggregate base. It goes under driveways, parking pads, pavers, slabs and Stone Screenings paths, and it compacts hard.

Recycled base rock is Class 2 base made from Road Base or asphalt, and it does the same work under drives, patios and slabs. Caltrans allows processed reclaimed asphalt and concrete in aggregate base, so it is a practical choice for subgrade. Some suppliers also call this crushed miscellaneous base, or CMB.

For surfacing, driveway gravel tops a compacted Class 2 base or dresses an existing drive. Walkway gravel gives paths a finer, walkable surface. Stone Screenings, or DG, is the fine, firm-packing material for paths and patios, laid over a compacted base.

Water needs clean stone. 3/4 inch drain rock, also called #57 stone, has no fines, so water moves through it in French drains and drainage trenches. Drain rock handles drywells, downspout runs and drainage behind retaining walls. Rip rap, also called rock slope protection, armors slopes and creek banks against winter runoff.

Sand and soil round out an order. Washed sand, also called concrete sand, levels and beds under slabs. Mason sand suits brick and block work, paver joints and play areas. Topsoil builds up planting areas, and garden soil fills raised beds. Shredded mulch holds moisture in beds through the dry season.

Ground and Conditions in Mountain View

Most rain here falls from late fall to spring, often in a few large winter storms and atmospheric rivers. That water soaks into sandy ground quickly, but it sits on or runs off clay soils and slopes. Where your lot falls decides how much drainage stone you need.

Heavy clay soils that crack when dry and swell when wet are extensive in the Coast Range valleys and hills, while sandy dune and beach soils sit along parts of the shoreline. On clay, plan on a compacted Class 2 base and a clean drain rock layer to move water away from the subgrade.

Winter also brings hillside runoff and slides on steep slopes, plus wave and storm erosion along the shoreline. Rip rap on slopes, creek banks and culvert outlets is the usual answer where runoff concentrates. The dry season from late spring into fall is the main window for base, driveway and paver work; saturated clay is what holds jobs up.
