Bulk Aggregates for Patios in Randolph, WI

Wisconsin Rock Supply handles gravel and aggregate delivery in Randolph, WI for two kinds of buyers: contractors who order by the truckload and homeowners building one patio. Both get the same material, and both start with traffic bond. Around Randolph the ground is lime-rich glacial till under a cap of silt loam, so what you put under a paver matters more here than the paver itself.

Materials for Randolph Projects

For patios and flatwork, bedding is the material that decides how the surface behaves after two winters. Traffic bond is a crushed dense-graded base that packs hard and locks up under vibration. Use it as the compacted base, not as the bedding.

Above that base, bedding and joints want finer material. Screenings, which many buyers call stone dust, are the standard paver and patio bedding here and also work as a hard-packing top dressing on a drive. Natural Pea Gravel and 3/4 inch crushed stone cover the other two common jobs.

Where the subgrade is soft or clay-heavy, breaker run goes in first as a coarse sub-base and gets capped with traffic bond. For a patio that sits against the house, a layer of clear stone or drain rock keeps water from stacking up behind the wall.

Ground and Conditions in Randolph

A patio fails from the bottom up. The first sign is a low corner that ponds after a rain, then pavers that rock underfoot, then joints that empty out. That pattern almost always traces back to a base that was too thin or never compacted.

Randolph sits in the South-central and southeast Wisconsin glacial plains and Kettle Moraine zone. Water collects in kettles, marshes, and low ground between drumlins and moraines, and slow-draining till holds spring rain and snowmelt near the surface. Sandy and gravelly outwash drains much faster, so two yards a mile apart can need different base depths.

Frost is the other driver. Frost leaves the ground earlier here than in northern Wisconsin, but silty and clayey spots still heave and soften during the thaw. Footings under the Uniform Dwelling Code go at least 48 inches down, and pavement frost depth runs 48 to 72 inches by late winter. A patio base of traffic bond at the right depth, compacted in lifts, spreads that movement instead of letting it crack the surface.

Timing matters too. Base, driveway, and paver work runs from the end of the spring thaw into late fall. Frozen ground stops compaction, and posted spring weight limits on county, town, and village roads slow deliveries while frost comes out.

Delivery to Randolph and the Surrounding Area

Order online and pick your material first, then your quantity. Bulk aggregate sells by the ton or by the cubic yard, and the two are not the same number. A yard of traffic bond weighs more than a yard of Natural Pea Gravel or topsoil, so decide which unit you are ordering before you compare totals.

To estimate, measure the area and multiply by the depth you want, then convert. For a patio, figure the compacted base separately from the bedding and add a little for settling. The site calculator does that math for you and turns your dimensions into tons or yards.

Delivery covers Randolph and Dodge County, including Beaver Dam, Watertown, Waupun, Mayville, and Horicon. Have the drop spot clear and reachable by a truck, and tell us where you want the pile. Bulk loads get placed where they can be worked from, not moved twice.

Questions from Randolph Buyers

What gravel is best for a driveway in Randolph?

Start with traffic bond, sold here as 3/4 inch Traffic Bond. It is a crushed dense-graded base that compacts hard and carries weight. Over soft or clay ground, put breaker run down first and cap it with traffic bond. Finish with driveway gravel if you want a finer surface, or screenings if you want a tight top that sheds water.

How much material will my project need?

Measure the length and width, decide your depth, and convert to tons or yards. Base stone goes deeper than bedding, so figure them as two separate numbers. For a patio, plan the compacted traffic bond base in lifts and add screenings for bedding and joints. The site calculator converts your dimensions and rounds to a workable order.

Get Your Patio Base Sized Right

Run your patio or pad dimensions through the calculator and order traffic bond, screenings, and drainage stone in one delivery. If your numbers look close between two amounts, size up the base and keep the bedding tight. Place your order online when the quantities are set.
