Large River Rock and Bulk Aggregates for Provo, UT

Utah Rock Supply handles gravel and aggregate delivery in Provo, UT, from untreated base course to large river rock. Untreated base course, shortened to UTBC, is the compacting base under drives, pads and slabs.

Around Provo the benches hold sand and gravel, while the low ground runs to silt and clay.

Materials for Provo Projects

Slope, swale and bank protection starts with coarse stone. Wasatch Front cloudbursts and spring snowmelt move water fast, and the right size stone holds a bank in place.

RipRap is the armoring stone for wash and arroyo banks, culvert outlets and irrigation ditch banks. It also covers cut slopes that take flash runoff.

Large River Rock runs 4 to 6 inches and suits dry creek beds, swales and slope cover. A smaller rounded stone moves when runoff picks up, so this size holds where it counts.

#4 Crushed Stone is a large clean stone for heavy drainage, trench bottoms and construction entrances. It stays open so water passes through.

Below that, the working materials get finer. Road base, sold as 3/4 inch minus or 1 1/2 inch minus, is the same untreated base course sized by top size.

Drain rock, also called washed rock, is the clean stone for French drains, footing drains and window wells.

For a walkable surface, crusher fines compact into a firm path or bed pavers. 3/4 inch crushed stone and 3/8 inch crushed stone cover drainage beds, pipe bedding and paver joints.

Delivery to Provo and the Surrounding Area

You order online, choose a quantity by the ton or by the yard, and pick a delivery date at checkout. A dump truck then tips the load at your site.

Each product page has a calculator if you want to size the load first.

Utah Rock Supply delivers across Provo and Utah County, including Orem, Lehi, Eagle Mountain, Spanish Fork and Saratoga Springs. A bulk load arrives as one tipped pile, so have the spot clear before the truck reaches you.

Ground and Conditions in Provo

Base, driveway and paver work runs from early spring into late autumn. Frozen ground stops compaction in midwinter, and July and August run dry enough that a base needs added water to compact properly.

Across the Wasatch Front and the Bonneville benches, the ground was sorted by Lake Bonneville. Sand and gravel sit in the benches and in the deltas at the canyon mouths, while finer silt and clay lie out on the valley floor.

Soils here are alkaline and low in organic matter, and new lots are often stripped to clay subsoil before anything is built.

That split matters for drainage. Bench gravel drains fast, but valley-floor silt and clay hold water, and shallow groundwater sits close to the surface in the low ground.

Spring snowmelt off the Wasatch and summer cloudbursts at the canyon mouths both arrive faster than the ground can take them.

Debris flows and flash flooding come out of the canyons onto the alluvial fans, and snowmelt cuts the bench slopes. Bare, dry ground sheds soil in a cloudburst.

Coarse stone on those banks and swales is what keeps the water from taking the ground with it.

Cold, dry winters bring repeated freeze-thaw in the valleys, so gravel drives and the edges of flatwork heave every spring. Each jurisdiction sets its own frost depth figure, so confirm it with the local building official.

Questions About Stone and Delivery in Provo

What stone should I use for drainage in Provo?

It depends on where the water goes. For French drains, footing drains and window wells, use drain rock, also called washed rock, because it is clean and stays open.

For heavy drainage and trench bottoms, #4 crushed stone is a large clean stone. For bank and swale protection, RipRap and large river rock hold against fast runoff.

What should I have ready when the truck arrives?

Have the drop spot clear and reachable, with nothing overhead and room for a truck to turn around. The load is tipped in one pile, so pick a spot you can work from.

If you ordered by the ton or the yard, the quantity is already set. Have your ground ready to receive the material before the truck pulls in.
