What is the difference between crushed stone and Natural Pea Gravel?

Crushed stone has angular, broken faces and locks together under a load, which is why base course and 3/4 quartzite work as a base. Natural Pea Gravel is rounded and stays loose, so it suits paths, play areas and dog runs. Use crushed stone where a surface has to hold, and Natural Pea Gravel where a walkable, rounded stone is wanted.

Should I order material by the ton or by the yard?

Both work, and the choice comes down to how the job was figured. Contractors who bid by weight order by the ton, and buyers working from a volume order by the yard. Each product page has a calculator for sizing the load, so you can settle the quantity before checkout.

Which stone is best for drainage in Union County?

Washed rock is the clean drainage stone for drain tile, drywells, sump and downspout runs and window wells. Where water moves faster, riprap handles culvert outlets, dam faces and stream banks. For tight bedding, 3/8 inch crushed stone works.

Ground conditions across Union County

The working season here runs from the spring thaw into late fall, the longest in the state. Wet spells break it when the silt soils are too soft to compact, so timing a delivery around that matters.

Across the Southeastern till plains and Big Sioux valley, loess-mantled till leaves deep silty prairie soils that crust and shed water. Shallow quartzite bedrock leaves water nowhere to go in places, and river flooding along the Big Sioux is a real driver.

That combination pushes drainage to the front of the material list. Washed rock and the larger clean stone grades carry water away where the ground will not.

Gullying on the dissected slopes and sheet erosion on bare silt soils in spring are the erosion drivers. Riprap and large river rock hold banks and outlets where water moves fast.

Frost still goes deep and freeze-thaw heaves drives, walks and slabs every spring. Frost depth is set by the local building official, and the residential code adopted in Sioux Falls lists 42 inches.

Choosing the right material

Lincoln County and Clay County both sit in Southeastern South Dakota and share this ground region. The till, the silty prairie soils and the quartzite bedrock close to the surface are the same across all three.

Because the ground matches, the material choice does not change much from one county to the next. Base course, gravel cushion and clean drainage stone cover the same jobs on the same soils.

Match the material to the job rather than the county line. Base course for a compacted base, gravel cushion under a hard surface, washed rock where water has to move.
