Crushed Stone, Sand and Gravel in Monrovia, CA

California Rock Supply handles gravel and aggregate delivery in Monrovia, CA. Most drive and pad work here starts with Class 2 base, the standard California base material. The long dry season means you can grade and compact for most of the year. Winter storm days are the main interruption, so plan your drop around them.

Materials for Monrovia Projects

Driveways and parking pads carry the most traffic in this market. Class 2 base is the material to start with. It is specified as Caltrans Class 2 aggregate base, and local crews also call it Class II base or class 2 base rock. Spread it in lifts and compact each one before the next goes down.

Recycled base rock works the same way under drives, patios and slabs. It is Class 2 base made from Road Base or asphalt, and Caltrans allows processed reclaimed asphalt and concrete in aggregate base. Ask for it if you want to keep the job on recycled material.

• Class 2 Base for driveways, parking pads and the compacted base under pavers, slabs and Stone Screenings paths.
• Crusher Run where you want a base that binds and compacts hard.
• Driveway Gravel to surface an existing drive or top a compacted Class 2 base.
• Stone Screenings for paths and patios that pack firm and need little water.
• Drain Rock for French drains, drywells and downspout runs.

Ground and Conditions in Monrovia

Rain arrives in a few winter storms after a long dry season. It runs off hardscape, hard dry ground and clay fast, so water needs somewhere to go before it reaches your base.

Soils across these valleys run from sandy loam to clay, and expansive clay in many basins and hills swells when wet and shrinks and cracks when dry. Wetting that clay lifts and drops what sits on top of it. That is why a slab or paver job here starts with a compacted Class 2 base and a drainage layer, not just fill dirt.

For drainage, 3/4 inch drain rock is clean stone with no fines, so water moves through it instead of sitting. Use it in French drains and trenches. Rip rap, also called rock slope protection, armors slopes and culvert outlets against winter runoff. On the hillsides, the first heavy storms carry debris, so get slope and drainage work finished before the wet months.

Garden and bed work is different. Stone Screenings, topsoil and shredded mulch go in over the dry season, when the ground is workable and easy to shape.
