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

Crushed stone is angular and comes in named inch sizes, such as 3/4 inch and 3/8 inch crushed rock. Pea rock is rounded and small, about 3/8 inch. Crushed stone locks into a pad or a drainage bed; pea rock stays loose, which suits walkways, play areas and pipe bedding.

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

Both work. Quantities are ordered by the ton or by the yard, and each product page has a calculator for sizing the load. Sort out which unit you want before you pick a delivery date at checkout.

Which stone is best for drainage in Oliver County?

Washed rock is clean and open, so it suits drain tile beds, sump discharge and foundation drains. For heavier drainage, 3/4 inch crushed rock works for bin pads and construction entrances. Around coulee banks and culvert outlets, riprap armors the ground against fast runoff.

Materials delivered in Oliver County

Class 5 is the standard North Dakota base gravel.

Cities and counties write those class numbers into their own street specifications. That is how material is described and ordered here.

Sand, fill and mulch round out the list. Mason Sand beds block and brick work and fills paver joints.

Fill Dirt raises grade before a gravel course goes down.

Shredded Mulch holds moisture in beds and tree rings through a dry, windy summer.

Ground conditions across Oliver County

Base, driveway and paver work runs from the end of the spring thaw into late fall. Frozen ground stops compaction through the winter.

Spring load restrictions slow hauling while the frost comes out. Time a delivery around that window.

Drainage across the Missouri Slope is well developed. Water moves fast down the draws and coulees instead of standing.

The problem is runoff arriving all at once and cutting a drive apart rather than ponding on it. Erosion shows up as gully cutting in soft shale and claystone.

Slumping and landsliding follow on steep river bluffs and cut slopes. Riprap armors those faces against spring runoff and wave action.

Winters here are long and severe, with deep ground frost and a hard spring thaw. That thaw heaves and softens gravel drives, approaches and township roads.

Frost depth is set by the city or county rather than by a statewide table.

Choosing the right material

Burleigh County, Morton County and Mercer County all sit on the Missouri Slope, the same ground region as Oliver County. The soil there is the same soft Fort Union sandstone, siltstone, claystone and lignite under a thin cover, with swelling clay in places.

Glacial material is patchy, and sand and gravel sit on the Missouri River terraces. That ground does not change the base or drainage choice from one of these counties to the next.

So the choice comes down to size and job. Coarse open stone for drainage, graded base for a compacted surface, and fine material for bedding and joint fill.
