Bulk Aggregates for Patios in Montrose, MN

If you are pricing gravel and aggregate delivery in Montrose, MN, you are likely weighing a few materials against each other before you commit. Minnesota Rock Supply serves both contractors and homeowners here, and the difference between a good build and a call-back often starts one layer below what you see.

Class 5 is the base most Minnesota work is specified from.

Montrose sits in Wright County on the Central Minnesota moraine and granite belt, where deep frost and repeated freeze-thaw move ground that was not built to hold it.

Ground and Conditions in Montrose

Across the Central Minnesota moraine and granite belt, the ground is pocked with lakes, sloughs and closed basins. Low spots pond through the thaw while sand and gravel terraces along the river valleys drain freely.

That is the failure mode a thin base shows here. A patio or drive laid over a wet subgrade heaves, and the pavers rock and separate at the joints.

The fix is a base that holds its shape through freeze-thaw and a bedding layer that stays flat. Deep frost and repeated cycles are hardest on loam and clay loam over till, and on flatwork built thin over a wet subgrade.

The Minnesota Residential Code footing table lists 3 feet 6 inches for its Zone II counties. That figure is a footing depth for new construction, not a rule for gravel base.

Materials for Montrose Projects

Bedding under pavers and flatwork is where the wrong choice shows up fastest, so it is worth starting there. Bedding has to compact flat and stay put, which is the job of Granite Fines.

Minnesota granite fines come from the Crushed Stone quarried in the St. Cloud belt, and they bed pavers, flagstone and patio stone and pack down on garden paths.

Below the bedding, the structural course does the heavy work. Class 5 is the standard Minnesota base, a compacted aggregate for driveways, parking pads, shed and garage bases and road base.

If you want a tighter crushed surface instead, Driveway Gravel covers Class 2 granite, Class 2 limestone and 3/4 inch minus.

Two more materials round out a flatwork job. Washed Sand, also sold as concrete sand, is used for bedding, levelling and sand under slabs and pavers.

Crusher Run is crushed rock with the fines left in, for bases and drives that need to bind and compact.

Delivery to Montrose 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 tips the load on site as one pile.

If you are not sure whether you need tons or yards, each product page has a calculator. Sizing the load before you order keeps you from running short halfway through the job.

Minnesota Rock Supply delivers across Wright County, including St. Michael, Buffalo, Monticello, Albertville and Delano.

What gravel is best for a driveway in Montrose?

Class 5 is the standard Minnesota base course. It compacts into a firm, stable surface for a drive or parking pad.

If you want a tighter 3/4 inch crushed surface, Class 2 is the surfacing class in the same spec. Many drives use Class 5 as the base and a surfacing layer on top.

How much material will my project need?

It depends on the area you are covering and how deep the layer needs to be. Each product page has a calculator you can use to size the load, and quantities are ordered by the ton or by the yard.

Buyers with a flat, well-drained site generally need less than those working over wet ground.

Size Your Load Before You Order

Work out your quantity with the calculator on the product page, then place your order online and choose a delivery date. A dump truck will tip the material on site.

Class 5, granite fines, washed sand and the rest of the range are ready to go to Montrose and the surrounding Wright County area.
