Large River Rock, Stone and Soil Delivery in Amherst, SD

What do you order when a ditch is cutting back across your drive? You start with coarse rock.

South Dakota Rock Supply handles gravel and aggregate delivery in Amherst, SD, and base course is where most ground work here begins.

Amherst sits in Marshall County on the Coteau des Prairies, where stony loam covers dense till and water moves slowly through it. That ground decides what you need.

Materials for Amherst Projects

Slope, swale and bank work is coarse stone work. Amherst sits on ground that sheds snowmelt and storm runoff fast, so the material at the edge has to hold where water runs hardest.

Riprap is the heaviest answer.

Large River Rock suits dry creek beds, draw bottoms and heavier decorative or erosion work where you want stone that will not move.

#4 Crushed Stone, sold here as 1 1/2 inch clean rock, handles heavy drainage, approaches and trench bottoms in wet ground.

Railroad Ballast is the large angular option for severe drainage and heavy equipment standing.

Moving down in size, 3/4 Quartzite is the pink Sioux Quartzite from the southeast corner, the hardest rock sold in this part of the state, and it works for drives, drainage beds and landscape stone.

Washed Rock, the usual Dakotas word for clean drainage stone, goes into drain tile, drywells, sump runs and window wells.

Below that, Stone Screenings bed pavers and flagstone and pack hard on walks. Top Soil finishes the job where a real growing layer is needed.

Ground and Conditions in Amherst

On the Coteau des Prairies, closed pothole basins with no outlet hold snowmelt and spring rain. Dense till under the topsoil takes water slowly, so yard edges and drive edges stay wet after the surface looks dry.

That is why drainage stone belongs in the plan from the start. Coarse clean rock gives water somewhere to go instead of letting it sit against a base.

Base, driveway and paver work runs from the spring thaw into late fall. Frozen ground stops compaction, and the frost boil weeks in early spring are the worst time to place material.

Winters here bring deep frost, repeated freeze-thaw and drifting. Gravel drives heave through the winter and soften badly when the frost comes out, so timing a delivery matters as much as the material.

Questions About Stone and Delivery in Amherst

What stone should I use for drainage in Amherst?

Start with Washed Rock for drain tile, drywells and sump runs, because clean stone lets water pass. For heavier flow at a culvert outlet or a bank, step up to Riprap or Large River Rock.

In wet ground, #4 Crushed Stone, sold as 1 1/2 inch clean rock, is a practical heavy drainage choice.

What should I have ready when the truck arrives?

Have a clear route to the site and a clear spot for the pile. A dump truck tips the load in one place and leaves, so the spot you choose is where the material stays.

Order your quantity by the ton or yard, and use the calculator on the product page if you want to size it.
