Large River Rock, Stone and Soil Delivery in Alma, WI

Start with the math, then pick the stone. For gravel and aggregate delivery in Alma, WI, Wisconsin Rock Supply sells by the ton, so you can figure your square footage, your depth, and your tonnage before you order. Traffic bond covers most drives and pads. On the steep ground above the river, though, the first load is often coarse stone for slope and bank protection.

Measure the area, set the depth, and convert. That number tells you what to order and keeps a hillside job from running short halfway through.

Materials for Alma Projects

Slope, swale and bank work drives this list. Coarse stone goes down first, then finer material caps it. Work from the coarsest size down to the finest.

RipRap is the heavy option for lakeshore, stream bank and culvert outlets. It armors a slope against waves, spring runoff and heavy rain. Breaker Run is coarse crushed stone with the fines left in, and it builds a sub-base over soft or clay ground. Cap it with traffic bond.

For drainage, Drain Rock handles French drains, foundation drains and downspout runs. 3/4" Crushed Stone, which many yards here call clear stone, works for drainage beds and backfill around foundations and pipe.

Traffic bond, also sold as 3/4 inch traffic bond, is the crushed dense-graded base that packs hard.

Finish with Screenings, the stone dust that packs hard under pavers and on walkways. Large River Rock suits dry creek beds and heavier decorative work where water needs to move.

Ground and Conditions in Alma

Timing matters as much as stone choice. Base work runs from the end of the spring thaw into late fall. Wet silt loam on steep grades ruts easily, and low valley sites should allow for high water after big storms.

This is Driftless Area ground: silt loam formed in windblown loess over sandstone and dolomite, thin and stony on steep slopes and some ridge tops, with sandy and silty river deposits on valley floors and terraces. Where bedrock is shallow, water also drains through cracks, sinkholes and springs.

Runoff on steep slopes washes that loess downhill and cuts gullies and stream banks, worst in heavy storms. That is why coarse stone belongs on the slope and at the outlet, not just at the bottom.

Frost drives the depth. Freeze-thaw cycles run into early spring, and silty soils hold water and soften as frost comes out. A thin base on a slope or at a hillside seep ruts easily. Frost depth runs at least 48 inches for footings under the Uniform Dwelling Code, and 48 to 72 inches under pavement by late winter.

Class II state highways and posted county, town and village roads carry spring weight limits while frost comes out. Plan the haul around that window.

Delivery to Alma and the Surrounding Area

Order online, choose your quantity by the ton or the yard, and we deliver bulk to your site. Coverage is easy to work out: one ton of most base material covers a known area at a set depth, so your square footage and depth give you the tonnage.

Lead time depends on the material and the season, so order ahead when the thaw opens the schedule up. A truck needs a clear, firm place to dump, and on a narrow valley lot that spot is worth picking before the driver arrives.

We deliver in Alma and across Buffalo County, including Mondovi, Fountain City, Cochrane and Nelson.

Questions from Alma Buyers

What stone should I use for drainage in Alma?

Match the stone to the water. Drain Rock and 3/4" Crushed Stone, which yards here call clear stone, handle French drains, foundation drains and downspout runs. For a swale or a culvert outlet, RipRap armors the slope against spring runoff and heavy rain. Where bedrock is shallow and water moves through cracks and springs, size up rather than down.

What should I have ready when the truck arrives?

A clear, firm spot to dump, and enough room for the truck to turn around. Mark anything you do not want buried, and know where you want the pile placed. On wet silt loam or a steep grade, wait for drier ground so the truck does not rut the drive. Have your tonnage and depth confirmed before the load shows up.
