Materials for Armour Projects

Raising grade is the job that comes first on a low, flat site. Fill Dirt builds a pad up before any base course goes down, and it backfills around foundations and shop slabs.

Once the pad is at grade, Base Course is the crushed base layer under drives, parking pads and shed floors.

Under concrete and asphalt, Gravel Cushion is the cushion course rolled out to a stable surface. It also acts as the crushed top course on a gravel drive.

For a finished drive surface, Driveway Gravel resurfaces an existing farm or acreage drive and tops a compacted base. For a finer, walkable surface on garden paths, Walkway Gravel is the smaller option.

Ground and Conditions in Armour

Across the James River Lowland and Lake Dakota Plain, the ground is flat to gently rolling glacial till over the silt and clay floor of glacial Lake Dakota. There is very little natural relief and little gravel at the surface.

That means a base built straight on the native soil sits on tight lake-bed silt. Fill Dirt and a compacted Base Course give you a working layer that the silt below cannot provide.

Almost no fall across the lowland means snowmelt and heavy rain sit on the surface. The tight silts below the topsoil drain very slowly, so water stays where it lands.

Sheet flow and ditch cutting follow heavy rain, and field runoff crossing a drive cuts gullies. Wind moves bare flat ground in spring.

A gravel cushion or washed rock layer at a low spot gives that water somewhere to go.

Work waits for the ground to dry in spring, and the flat black soils stay soft far longer than the coteau does. The season then runs through to freeze-up.

Cold winters bring deep frost and repeated freeze-thaw. The flat ground and heavy soils make the spring thaw slow and muddy, so timing matters as much as material.

What is the best base under pavers in Armour?

Start with a compacted layer of Base Course over fill where the grade is low. Washed Sand beds and levels the pavers above that, and Stone Screenings fills the joints.

On the tight lake-bed silts here, the base layer is what keeps the surface from moving when the ground stays wet.
