Mason Sand for Patios in South Pasadena, CA

If you have a patio, walkway or driveway on the books in South Pasadena, CA, gravel and aggregate delivery is how you get the base and bedding material to the site. California Rock Supply sells Class 2 base, sand and decorative stone online, with delivery across Los Angeles County.

Patio work here starts with a compacted Class 2 base, then a sand bedding layer under the pavers. The soils across the Los Angeles basin swing from sandy loam to expansive clay, so what you put under the flatwork matters as much as the surface.

Pavers and flatwork need a bedding layer that stays flat and drains. That means a compacted base first, then a thin, screeded sand course the pavers seat into. Get the bedding right and the patio stays level through the wet season.

Class 2 base is the standard base material in California, and Caltrans specifies it as Class 2 aggregate base. Contractors here also ask for it as class ii base, class 2 aggregate base or base rock. It goes down under the patio, gets watered and compacted, and carries the load so the pavers do not settle.

Recycled base rock is the same idea made from Road Base or asphalt, and Caltrans allows processed reclaimed asphalt and concrete in aggregate base. Some suppliers around here call it crushed miscellaneous base, or CMB. It works under drives, patios and slabs the same way.

Mason sand is the bedding layer. Screed it thin, set the pavers, and sweep more into the joints. For a concrete slab instead of pavers, washed sand is the leveling and bedding course. Where you want a softer path surface, Stone Screenings packs firm over a compacted base.

For drainage, 3/4 inch drain rock is clean stone with no fines, so water moves through it. Use it in French drains, drainage trenches and behind retaining walls. Natural Pea Gravel fills play areas and walkway beds, and river rock or cobble handles decorative borders and dry creek beds.

Ground and Conditions in South Pasadena

A thin base is the failure you see on patios here. The pavers look fine for a season, then dip and rock at the corners where the base was too shallow or never compacted.

The ground is the reason. Soils in this basin run from sandy loam to clay, and expansive clay is common. That clay swells when it gets wet and shrinks and cracks when it dries. Under a slab or a paver field, that movement telegraphs straight up through the surface.

Rain arrives in a few big winter storms and atmospheric rivers after a long dry season. It runs off hardscape and dry ground fast, and wetting expansive clay makes it swell under paving. So the base needs to be deep enough, compacted in lifts, and paired with a drainage layer that moves water away.

The long, warm, dry season suits base and paver work for most of the year. Winter storm days are the main interruption. If you are pouring or compacting in the wet months, plan around the rain and keep the subgrade covered.
