Buy Fill Dirt in Onalaska, WI

If you are grading a lawn, building raised beds, or prepping a driveway base, we handle gravel and aggregate delivery in Onalaska, WI. Wisconsin Rock Supply stocks fill dirt, pulverized topsoil, garden mix and traffic bond. On valley terraces here, silty river deposits drain slowly, so the base you build matters as much as the material you spread on top.

Materials for Onalaska Projects

Most jobs in the Driftless Area start with moving grade. Fill dirt raises low spots and backfills around a foundation before any topsoil goes down. For lawns and bed prep, pulverized topsoil (many crews here call it black dirt) spreads fine and takes seed well. Raised beds and planting areas do better with garden mix, a topsoil and compost blend.

Once the grade is right, base and drainage materials finish the job.

• 3/4" Traffic Bond: the crushed dense-graded base that packs hard under driveways, parking pads and shed floors.
• Breaker Run: coarse stone with fines for a heavy sub-base over soft or clay ground and for construction entrances.
• Drain Rock: French drains, foundation drains and downspout runs.
• Screenings: paver and patio bedding, plus a hard-packing top dressing on drives.
• RipRap: shoreline, culvert outlet and slope armoring against waves and spring runoff.

For a finer surface, Walkway Gravel covers paths, and Top Soil finishes any bed you cut into the slope.

Ground and Conditions in Onalaska

Rain and snowmelt run fast off the steep ridges into narrow valleys here. Heavy storms can flood valley towns, and where limestone and dolomite sit shallow, water also drains through cracks, sinkholes and springs. That changes how you build on a terrace.

The soil is silt loam formed in windblown loess over sandstone and dolomite, thin and stony on steep slopes and some ridge tops. Silt holds water and softens as frost comes out, so a thin base on a slope or at a hillside seep ruts easily. Under pavement, frost reaches 48 to 72 inches by late winter, and footings need at least 48 inches under the Uniform Dwelling Code.

Runoff on steep slopes and ridge-top fields washes loess downhill and cuts gullies and stream banks, worst in heavy storms. If you are building a drive into a hill, put breaker run down first and cap it with traffic bond. Where water wants to move, use clear stone or drain rock instead of a tight base.

Base work runs from the end of the spring thaw into late fall. Wet silty soil on steep grades ruts easily, so time your haul when the ground is firm. Low valley sites should allow for high water after big storms, and spring weight limits post on county, town and village roads while frost comes out.

Delivery to Onalaska and the Surrounding Area

Bulk material arrives on a dump truck and is tipped where you want it, so plan the drop before the truck rolls. Pick a spot the driver can reach and turn around in, and keep it clear of overhead wires, parked cars and soft ground. If the truck cannot get close, expect to move the pile by machine or wheelbarrow.

Order online and size the load by the ton or by the cubic yard. Measure your length, width and depth, then use the calculator on the product page to turn that into a quantity. A driveway base, a patio bed and a topsoil layer all take different depths, so figure each one separately.

We deliver across Onalaska and La Crosse County, including La Crosse, Holmen, West Salem, Bangor and Rockland. Split loads are easy to arrange when one project needs fill dirt and another needs base.

Questions About Ordering in Onalaska

Can I order material by the ton for delivery in Onalaska?

Yes. Products are sold by the ton or by the cubic yard, and you enter the quantity when you order. Most buyers figure volume first from length, width and depth, then let the calculator convert it. If you are unsure, measure the job and let the calculator size the load before you check out.

What stone should I use for drainage in Onalaska?

Use washed stone with the fines screened out, because silt and dust clog a drain. Drain rock, clear stone or #57 stone all work in French drains, foundation drains and downspout runs. In the Driftless Area, where water finds cracks and springs in the bedrock, keep the stone clean and daylight the outlet.
