Bulk Gravel Delivery to Buffalo, MN

If you are planning gravel and aggregate delivery in Buffalo, MN, the job usually starts with a driveway, a patio base or a drainage run. Minnesota Rock Supply sells the bulk material for all three, and Class 5 is where most of that work begins.

Buffalo sits in Wright County on ground that is part of the Central Minnesota moraine and granite belt, where loam sits over till between the lakes. That ground tells you what a base has to do before you pick a material.

Ground and Conditions in Buffalo

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

A base built too thin over a wet subgrade shows it in the first spring thaw. The surface pumps, ruts and breaks apart at the edges, and no amount of new topping fixes a soft layer underneath.

The fix is a compacted base that spreads the load and sheds water instead of holding it. Deep frost and repeated freeze-thaw work on that same weak ground, so a drive that stays put here is one with enough base under it.

Base, drive and paver work runs from the thaw into late autumn. Spring load limits go up on Central zone roads in March and come off in late April or early May, which is worth knowing when you plan a delivery.

Materials for Buffalo Projects

Bedding under pavers and flatwork is the job that decides how the finished surface looks in three years. Get the bedding right and the pavers stay flat.

Get it wrong and the whole patio rocks.

Class 5 is the Minnesota base course. It goes down under driveways, parking pads, shed and garage bases and road base.

Class 5 is also called Class 5 gravel, Cl 5 or Class 5 aggregate base.

Granite fines are the bedding material itself. Minnesota granite fines come from the Crushed Stone quarried in the St.

Cloud belt, and they bed pavers, flagstone and patio stone. Granite Fines are also sold as screenings or stone screenings.

Washed sand is the other bedding choice, for levelling and sand under slabs and pavers. Washed Sand is also sold as concrete sand, and it beds and levels where a finer, more even layer is wanted.

Yards sell it as Class 2 granite, buff limestone or red limestone.

Driveway Gravel covers Class 2 and driveway gravel for topping an existing drive or finishing over a compacted base.

For anything wet, 3/4 clear rock is washed with the fines taken out, which is what clear means in Minnesota. It drains where Class 5 would hold water, and it goes under slabs and around footing drains.

3/4 Clear Rock is also called radon rock or under-slab rock.

Delivery to Buffalo and the Surrounding Area

You order online and choose a quantity by the ton or by the yard. That is the whole decision on volume, and each product page has a calculator to help you size the load.

A dump truck tips the load in one pile at the site. From there the material is yours to move, and a pile set close to the work keeps the hauling short.

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

Questions About Gravel in Buffalo

What gravel is best for a driveway in Buffalo?

Start with Class 5 as the base course, then finish with Class 2 or driveway gravel over it. On ground that holds water, 3/4 clear rock under the base helps water move instead of sitting.

In this part of the state, where loam sits over till and low spots pond through the thaw, that layered approach is what keeps a drive from rutting.

How much material will my project need?

Each product page has a calculator, and quantities are ordered by the ton or by the yard. Measure the area you are covering, then work from the calculator rather than guessing at the pile size.

It is the quickest way to land on a number you can order with confidence.

Size Your Load Before You Order
