Gravel Delivery in Minnesota

Ice did much of the work on the ground around the Twin Cities. Glaciers in this part of the country can leave behind broad layers and ridges of mixed sand, gravel, silt and boulders, and rivers of meltwater sort that mix into clean beds of sand and rounded stone. That history is why washed sand and round gravel are common in the upper Midwest. Crushed stone is a separate product, made by breaking solid rock in a crusher so each piece has sharp, fresh faces.^[1]

The two products behave in different ways in a yard. Round gravel such as Pea Gravel and River Rock rolls under a tire or a boot, which is fine in a garden bed or a drain and poor on a driveway. Crushed products such as #57 Crushed Stone, 3/4" Crushed Stone and Road Base lock together when packed, so they hold a level surface under a car and stand up to the push of frost far better.^[1]

The ground at the Minneapolis center point stands 840 feet above sea level, and the Saint Paul center point 720 feet. Those numbers each mark one spot. A lot on a bluff and a lot down near a river flat can sit well apart from them and from each other. Ground that slopes toward a house or sits in a low pocket will need more drainage work than a lot on a gentle rise, so look at where water goes on your own land after a spring melt.^[1]

Soil in a city yard is rarely what nature left. Decades of grading, fill and old foundations mean one side of a lot can be loose sand while the other is packed clay. Dig a test hole or two before you plan a driveway or patio. If the shovel slides through sand, the subgrade will drain on its own. If it pulls up sticky, smooth soil, plan on fabric and a thicker base.^[1]

Asphalt Millings and Crushed Concrete come from old pavement that has been ground or crushed and screened. Each of them packs into a firm surface and makes a common choice for a rural lane, a parking pad or a shop yard in a cold climate. They also bind well when compacted, which helps them resist the frost that loosens a plain gravel surface.^[2]

Cold sets the rhythm of the year. The weather station used for Minneapolis logs 147 days a year at 32 F or colder, and the Saint Paul station 146 days. That count adds up every day with a low at or below freezing, from light autumn frosts to the deep cold of midwinter. Many of those days thaw in the afternoon, and each swing from frozen to thawed works water into and out of the top of the ground.^[2]

A winter delivery is possible when the truck can reach the spot. Frozen ground carries a heavy load well, so a cold morning can be the cleanest time for a drop on a lawn. Clear the drop spot and the path in, push snow banks back to give the truck room, and set tall stakes at the edges of the drive. A pile of stone can wait under snow until spring, but a frozen pile of fines such as Road Base or Stone Dust Screenings can be hard to break up until it thaws.^[2]

Spring thaw is the riskiest time for a yard. Once the frost leaves, the top of the ground holds a lot of water and stays soft for a while. A loaded dump truck can sink into a lawn that looked solid a week before. Plan spring drops on a paved drive or a firm gravel apron, or wait until the yard has dried out.^[2]

Precipitation is moderate. The Minneapolis station averages 34.4 inches a year and the Saint Paul station 29.2 inches, counting rain and the water in melted snow together. Summer storms can still drop a lot of water at once, and a fresh pile of fines can wash out onto a sidewalk. Cover a pile you will not spread that week.^[2]

City lots bring their own limits. Alleys, detached garages at the back of a lot, narrow side yards and overhead lines are all common in older neighborhoods. A dump bed rises well above the cab, so look up over the drop spot. Tell Gravel Valet about a tight alley, a low wire or a soft boulevard when you order.^[1]

Driveways and alley pads built to resist frost lead the list. With 147 days a year at 32 F or colder logged at the Minneapolis station, a shallow base will heave. Dig down to firm soil, lay a woven fabric on anything fine or sticky, and put a coarse layer of #4 Crushed Stone or 1-1/2" Crushed Gravel at the bottom so water can drain before it freezes. Pack Road Base or Crushed Concrete over it in thin lifts, and finish with 3/4" Crushed Stone or Driveway Gravel.^[2]

Shape the surface for snow. Plowed snow piles along the edges of a drive and melts slowly in spring. A crown down the middle sends melt to the sides, and a shallow trench of Drain Rock along the low edge carries it away from the garage slab. Riprap holds the bank where a ditch or a culvert lets fast spring water out.^[2]

Basement drainage is a big job in a cold state. Water that pools against a foundation can freeze and push, and it can find its way inside during the thaw. A French drain filled with #57 Crushed Stone around a perforated pipe and wrapped in fabric moves water away from the wall. Window wells drain better with a layer of clean Pea Gravel at the bottom.^[2]

Garden beds come back to life fast once the ground warms. Raise beds with Topsoil or Garden Soil, mix in Compost, and cover them with Brown Shredded Mulch or Wood Chips. A thick mulch layer shields roots from the deep cold of winter and slows the heave of freeze and thaw in early spring. River Rock suits a bed next to a foundation.^[2]

Patios and walks use the finer products. Pavers need a deep, packed base of Road Base and a thin bed of Concrete Sand to set them level, and Mason Sand swept into the joints. Walkway Gravel and Decomposed Granite make a firm garden path. Playground Sand fills a sandbox. Edge every path with steel or stone, since frost and snow plows both nudge loose gravel out of place. Our area calculator turns each layer into tons.^[1]
