Bulk Gravel and Stone Delivery in Sauk County, WI
Start with the math before you pick the stone. Figure the square footage, decide how deep the layer needs to be, then convert that volume to tons or yards.
Ground here ranges from silt loam over sandstone and dolomite in the Baraboo and Reedsburg coulees to deep sand and gravel around Wisconsin Dells. That split decides how thick a base you need and how well water moves under it.
Materials Delivered in Sauk County
Coarsest to finest, this is what moves in Sauk County and what each size is good for.
For drives and pads in Sauk County, start with traffic bond. It is a dense-graded base that packs hard under a plate or roller. Some yards label it road gravel.
Breaker Run is the coarse sub-base that goes under traffic bond. Use it to correct soft subgrade and to build construction entrances, then cap it with traffic bond.
Ground Conditions Across Sauk County
Base work runs from the end of the spring thaw into late fall. Wet silty soil on steep grades ruts easily, and low valley sites should allow for high water after big storms. Class II state highways and posted county, town and village roads carry spring weight limits while frost comes out.
In the Driftless Area and western coulees, silt loam sits over sandstone and dolomite, thin and stony on steep slopes and some ridge tops, with sandy and silty river deposits on valley floors. That ground drains through cracks, sinkholes and springs where bedrock is shallow, so plan a drainage layer, not just a base.
In the Central Sands around Wisconsin Dells, deep sand and gravel left by glacial meltwater drain fast, with peat and muck in the wetlands and marshes. Sandy ground can usually be worked soon after frost leaves, but low, wet sites and peat stay soft longer.
Frost sets the depth. Footings need at least 48 inches under the Uniform Dwelling Code, and pavement sees 48 to 72 inches of frost by late winter. Silty soils hold water and soften as frost comes out, so a thin base on a slope or at a hillside seep ruts easily.
Erosion follows the same split. On steep coulee slopes and ridge-top fields, runoff washes loess downhill and cuts gullies and stream banks. On the flat, fast-draining sand, erosion shows up mainly where loose sand is left bare on slopes, cut banks and flowage shores.
Delivery Across Sauk County
Order online from Wisconsin Rock Supply, and a dump truck brings the load to your site on the delivery date you pick at checkout. Coverage runs across the county, including Baraboo, Reedsburg, Prairie du Sac, Sauk City, Spring Green, Plain, North Freedom, Merrimac, La Valle, Rock Springs, Loganville, Wisconsin Dells and Hillpoint.
Size the load before you order. Base and fill are usually sold by the ton because weight is what the truck carries. Bedding sand, topsoil and mulch are often easier to picture by the cubic yard.
Lead time depends on material and where the truck is headed, so build the order into your schedule rather than the day you break ground. A bulk delivery means a dump truck and a place to put the pile, so keep the gate clear and the driveway firm enough to take the weight.
Choosing the Right Material
Next door in Columbia County, lime-rich glacial till sits under a cap of silt loam loess, with sand and gravel in outwash plains, kames and moraine hills, plus peat and muck in marshes and kettle bottoms. That loess cap and the kettles change the base call: expect more attention to a stable sub-base and to draining wet spots than you would on a coulee slope.
Juneau County spans the Central Sands and the Driftless Area and western coulees, so part of it works like Sauk County's sandy ground and part like its ridges and valleys. Dane County also spans two zones, the glacial plains and Kettle Moraine along with the Driftless Area and western coulees.
Match the material to the job. Traffic bond for a drive or pad, Breaker Run under it where the subgrade is soft, Drain Rock or 3/4" Crushed Stone where water has to move, Screenings for bedding pavers, and Top Soil or Garden Soil once the grade is right.
Questions About Gravel and Stone in Sauk County
What is the difference between crushed stone and Natural Pea Gravel?
Crushed stone is angular and mechanically crushed, so the pieces lock together when compacted. Natural Pea Gravel is round and smooth, which makes it easy to walk on but poor at holding a base. Use crushed stone under driveways, pads and drainage.
Should I order material by the ton or by the yard?
Heavy base and fill are usually ordered by the ton, since that is what the truck hauls. Sand, topsoil and mulch are often easier to plan by the cubic yard because you are filling a measured space. Measure your square footage and depth, and the volume converts to either one.
Which stone is best for drainage in Sauk County?
Drain Rock is the workhorse for French drains, foundation drains and downspout runs. In the coulees, where water moves through cracks and springs in the shallow bedrock, a clean washed stone keeps the void space open. In the sandy Central Sands, drainage still matters at low, wet sites and around foundations.
