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

Both work, and the right one depends on how you measured the job. If you worked from a plan or a takeoff in tons, order by the ton. If you measured in volume, order by the yard. Each product page has a calculator that converts between the two so the quantity matches the pile that arrives.

Which stone is best for drainage in Isanti County?

Drainage here means clean, washed, open-graded rock with the fines taken out. For French drains, drywells and footing drains, 1 1/2 inch clear drainage rock is the usual choice. For narrower trench work, 3/4 inch clear rock and 3/8 inch crushed stone both move water and bed pipe well.

What do I need to have ready for a bulk delivery?

The truck tips the load in one pile, so the spot needs to be reachable and clear. Have the pile location marked and the overhead lines checked before the truck arrives. Choose your delivery date at checkout and the driver brings the load to that point on site.

Class 5 is the standard Minnesota base course.

County highway departments and cities write their own standards against the same class numbers, so Class 5 is how a base is specified here. Order it for driveways, parking pads, shed and garage bases and road base.

Choosing the right material

Anoka County sits on different ground. Its Twin Cities metro ground runs from the Anoka sand plain to Grantsburg and Des Moines lobe till, with limestone and sandstone in the bluffs.

Red drift, sandy moraine and outwash sand are what you work with here. That difference shows up in drainage and in how a base holds together.

Sherburne County shares the same ground region as Isanti County: the East central sand plain and St. Croix moraine.

Chisago County shares it too, so the material reasoning is the same.

Ground conditions across Isanti County

On the East central sand plain and St. Croix moraine, bare sand blows and washes readily on open lots and fresh grading.

Water moves through sand fast, and tight red till on the moraine sheds it instead.

A base that is too thin shows up as ruts and soft spots where the sand below pumps. A clean, open-graded stone lets water through; a fines-bearing material like Class 5 binds and compacts into a surface.

Sand drains and refreezes quickly, so drives and walks move with each cycle rather than once in the spring. Frost depth is 3 feet 6 inches (42 inches) in Isanti County, set by the building official for footings.

Spring load limits go up on Central zone roads from March into late April or May, which sets the working season for anything hauled in.
