Materials for Letcher Projects

Base and driveway surfacing carries the work around Letcher. Base course, also called aggregate base course or 3/4 minus, is the crushed base layer under drives, parking pads and shop slabs.

Gravel cushion is the South Dakota term for the cushion course rolled out under concrete and asphalt. It also acts as the crushed top course on a gravel drive.

For the drive surface itself, Driveway Gravel resurfaces an existing farm or acreage drive and tops a compacted base. Walkway Gravel gives garden paths a finer, walkable surface than a drive.

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

#57 Stone, also called 1 inch washed rock, covers drain tile beds and concrete aggregate.

Sand and soil round out the order. Mason Sand beds brick and block work and fills paver joints.

Top Soil, or black dirt, builds a real growing layer over the tight lake-bed silts.

Ground and Conditions in Letcher

Letcher sits on 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, with deep dark prairie soils and very little natural relief.

Almost no fall crosses this lowland, so snowmelt and heavy rain sit on the surface. The tight lake-bed silts below the topsoil drain very slowly.

A drive here has to move water off the surface rather than rely on the ground to take it.

That standing water shows up as sheet flow and ditch cutting after heavy rain. Field runoff crossing a drive gullies it, and bare flat ground blows in spring.

A crushed base spreads the load and holds its shape where bare soil will not.

Cold winters bring deep frost and repeated freeze-thaw. The flat ground and heavy soils make the spring thaw slow and muddy.

Work runs from the dry stretch after thaw through to freeze-up.

Frost depth for footing work is set by the local building official. Deep frost is the reason a base layer needs to be built to the depth your project calls for.

Delivery to Letcher and the Surrounding Area

Bulk material arrives by dump truck and is tipped on site in one pile. Have the drop spot clear and reachable, with room for the truck to pull in and out.

A firm, dry approach keeps the truck from cutting ruts in soft ground.
