What is the difference between crushed stone and Natural Pea Gravel?

Crushed stone has angular faces from a crusher, so it binds and compacts when it is worked into place. Natural Pea Gravel, which Minnesota yards also call pea rock, is rounded and smooth. It does not lock together, so it suits walkways, play areas and drainage rather than a compacted base. Clear rock is crushed and washed with the fines taken out.

Should I order material by the ton or by the yard?

Both are offered, so order whichever unit you are set up to work in. Each product page has a calculator to size the load. Quantities are ordered by the ton or by the yard, so pick one unit and stay with it. If you are unsure which unit suits your project, the calculator is the place to start.

If you are building a driveway, setting a paver patio or running drainage away from a foundation, gravel, stone and aggregate delivery in Washington County, MN starts with the right base material. Minnesota Rock Supply sells bulk aggregate online and delivers it across the county.

Class 5 is the base most drives, parking pads and shed bases here start from. It is a Minnesota class.

Materials Delivered in Washington County

Minnesota yards name aggregate by class and by size, and that is how the material is listed here. Each product below links to the page where you can size the load.

Fines and screenings bed pavers and surface paths. The washed products drain.

Keeping those two jobs apart is most of picking the right material.

Base and gravel

Class 5 is a compacted base for drives, pads and road base. Crusher Run is crushed rock with the fines left in, for base and drives that need to bind and compact.

Minnesota yards sell that by class or by a minus size more often than by the name crusher run. Walkway Gravel suits garden paths that need a finer, walkable, compacting surface.

Washed stone

Clear rock is washed with the fines taken out. Use it for drainage beds, construction entrances and trench backfill.

3/8" Crushed Stone handles fine drainage and pipe bedding.

Foundation rock, which some yards call radon rock, is the clean washed rock under basement slabs and around footing drains. It also forms the gas-permeable layer beneath the passive radon system Minnesota requires in new homes.

Sand, soil and decorative stone

Mason Sand goes into brick and block work, paver joints and play areas. Washed Sand, also sold as concrete sand, is for bedding and levelling under slabs and pavers.

Fill Dirt raises grade and backfills before a Class 5 course goes down.

Garden Soil fills raised beds and planting areas.

For decorative work, Minnesota River Rock and Large River Rock cover beds, borders and dry creek beds.

Choosing the Right Material

Chisago County sits in East Central Minnesota, on the sandy St. Croix moraine and the eastern end of the Anoka sand plain.

That ground carries clean sand and gravel in the outwash and sandy loam over till on the ridges.

Ramsey and Dakota counties sit in the Twin Cities metro, the same ground region as Washington County. Several different grounds lie inside one short drive there.

That includes the Anoka sand plain, Grantsburg lobe till, sand and gravel terraces along the Mississippi and Minnesota, and Platteville limestone over St. Peter sandstone in the bluffs.

The ground is the same as Washington County, so the material choice does not change.

Ground Conditions Across Washington County

Across the Twin Cities metro, water moves at very different speeds depending on where you are. Sandy ground north of the rivers takes water fast.

Till in the southern and western suburbs drains slowly.

Hard surfaces across the built-up core concentrate runoff. The river terraces and bluff faces move water quickly down to the Mississippi and Minnesota.

That difference decides which layer a job needs. A slow-draining subgrade that holds water is where a clean washed stone drainage layer earns its place.

Fast sandy ground needs less of it.

Erosion shows up as bluff and ravine cutting above the Mississippi, Minnesota and St. Croix, gully cutting on graded lots, and streambank scour in urban creeks after heavy rain.

Riprap and large river rock armour those slopes against ice, wave and spring runoff.

The working season here is the longest in the state, running from the spring thaw into late autumn. Spring load limits go up on Metro zone roads in early March and come off in mid-April.

Cold winters bring repeated freeze-thaw and heaving drives, walks and slabs wherever a clay loam subgrade holds water under a thin base. The Minnesota Residential Code footing table sets 3 feet 6 inches for its Zone II counties.

That is a footing depth set by the building official.
