Mason Sand for Patios in Crooks, SD

South Dakota Rock Supply handles gravel and aggregate delivery in Crooks, SD, and the working season here runs from the spring thaw into late fall. Wet spells shut the silt soils down while they are too soft to compact.

That timing decides when a load of base course can go down. Plan the flatwork first, because everything under it has to be right before the pavers land.

Ground and Conditions in Crooks

Crooks sits on the Southeastern till plains and Big Sioux valley ground, where loess-mantled glacial till leaves deep silty prairie soils. Those soils crust over and shed water instead of taking it in.

Sand and gravel run along the Big Sioux valley, and Sioux Quartzite bedrock sits close to the surface around this corner of the state. Water that gets past the silt has nowhere to go in places.

On a paver patio or a walk, that shows up as a thin base that moves. The silt holds moisture, frost heave lifts the slab every spring, and the joints open.

The fix is a real granular base under the bedding layer, not more sand. Screenings or mason sand bed the pavers, and a compacted course beneath them carries the load.

Frost goes deep here even in the mildest winters in South Dakota. The residential code adopted in Sioux Falls sets frost depth at 42 inches, and the local building official sets the figure in other towns.

Materials for Crooks Projects

Bedding is where flatwork is won or lost. Screenings, also called crusher dust or chips and dust, bed pavers and flagstone and fill the joints, and they pack hard under a walk.

Mason sand is the other bedding choice, and it also serves brick and block work, paver joint sand and play sand. Washed sand, or concrete sand, beds and levels under slabs and pavers.

Under all of it goes base course. It is also called aggregate base course, 3/4 minus or crushed base, and it builds driveways, parking pads and shop and shed slabs.

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

For drainage, washed rock, also called drain rock or clean rock, handles drain tile, drywells, sump and downspout runs and window wells. Natural Pea Gravel, or pea rock, suits paths, play areas and dog runs where a rounded, walkable stone is wanted.

Topsoil, or black dirt, builds a growing layer over stony till, and shredded mulch holds moisture in beds through a dry, windy summer.
