“Six tons of washed sand for a concrete pour on a garage slab near Clyde Park. Clean, no silt clouding the mix, and the finished slab came out smooth with no weak spots after curing. Montana Rock Supply beat the ready mix supplier's aggregate price by a good margin.”

- Washed; free of clay, silt and organic debris
Montana work areas can face dry ground, sudden rain, and deep seasonal freezing. East of the Continental Divide, gumbo soil can become difficult to handle when wet, while valley gravel farther west behaves differently. Washed Sand gives concrete preparation, utility work, and surface leveling a consistent material apart from soil removed during excavation.
Processing washes away clay and silt along with organic matter, so the sand is suited to jobs that call for a clean aggregate. For a utility line, place the sand on the prepared trench bottom before the pipe is set. Its ability to move into confined spaces helps form an even bedding layer around the line, while keeping surrounding soil out of that part of the installation.

Common Uses
Concrete & Mortar Mixing
Concrete and mortar mixes use washed sand as a main aggregate. Its even particle sizing supports uniform batches for structural pours such as foundations, slabs, and walls.
Backfill & Trenching
Place washed sand around foundation digs, in post holes, and in utility-trench backfill. It packs well where access is tight and helps keep drainage lines free of unwanted material.
Leveling & Grading
For site prep, washed sand can build drainage slope and bring low ground up to grade. It spreads into irregular spots readily, then packs down to a uniform working surface.
Pipe & Cable Bedding
Washed sand forms an even bed around buried pipes, conduits, and cables. It settles around the installation without affecting coatings, helping protect against movement and concentrated pressure.
Why Choose Washed Sand
Washed Material
The washing process separates out clay, silt, and organic debris that may interfere with drainage or concrete performance. This leaves sand suited to jobs where a washed aggregate is called for.
Uniform Grain Size
The grain-size range in washed sand is even, which helps with concrete batches, bedding, and fill placement. That uniformity makes its behavior easier to plan for across the job.
Versatile All-Purpose Material
Washed sand covers common site tasks, including concrete work, pipe bedding, and grading. Using it across these applications can reduce the number of specialty materials brought to the job.
Bulk Ordering
Bulk delivery lets a project receive washed sand instead of using bagged material, with pricing by the ton. A single load may cover sand needs across more than one construction phase.
Frequently Asked Questions About Washed Sand

Community Court Ready Before The Picnic
Washed sand went down on the community hall court in Judith Gap ahead of the summer picnic, eight tons total. Montana Rock Supply had the load out within a day of the order, and we leveled it out over two evenings before the big day. The court played true for the whole tournament, no washboard texture underfoot, and neighbors are still talking about how good the volleyball games looked.

Patio leveled, needed a bit extra
Three tons of washed sand to level pavers on a small patio near Grass Range. Clean and easy to screed flat. Only issue is we ended up needing another half ton to finish the last row, more than the estimate suggested.

Cattle Get A Dry Beach
Ten tons of washed sand went down along forty feet of our stock pond bank to give the cattle a firm beach instead of the mud they'd been standing in. The bank drops off fast right there, so the tandem had to back down real slow and stay off the soft edge the whole way to keep from sliding in. Montana Rock Supply's driver took his time and got it done without incident. Took us two weekends of raking and spreading by hand to get it level, but the cattle already use it every morning and the water stays a lot clearer now.
