Bulk Aggregates for Patios in Colo, IA

Iowa Rock Supply handles gravel and aggregate delivery in Colo, IA, and the season sets the schedule. Compaction waits for the frost to come out and for the flat ground to shed its spring water.

Class A roadstone is the base most of that work starts from, and you can order it by the ton or the yard. A wet spring shortens the window, so the earlier you size the load, the better the date you pick.

Ground and Conditions in Colo

Colo sits on the Des Moines Lobe, the youngest glacial ground in Iowa. The till here is thick, compact and pebbly, and it runs deep.

This is pothole country. The drainage network is young and inefficient, kettles and closed depressions hold water, and most of the ground only drains at all because it is tiled.

Snowmelt and spring rain sit on the surface where the ground below is still frozen. A paver patio set on a thin base shows the result: the surface rocks, joints open, and the edges drop.

The fix is a base that spreads the load and a bedding layer that stays put. Base and paver work runs from late spring to the fall freeze here, so plan the pour and the bedding around that window.

Materials for Colo Projects

Bedding is what makes a patio last, and bedding is where most of the material decision sits. Limestone screenings are the fines left over from crushing, and they bed pavers and flagstone, fill joints, and top a compacted base.

Under that bedding goes the base course. Class A roadstone is crushed limestone with the fines left in, so it binds and compacts, and it carries driveways, parking pads, shed bases and farm lanes.

For a new drive, a soft spot or a lane that carries heavy equipment, 1 inch roadstone is the coarser grade, laid under a finer surface course.

Where water has to move rather than sit, clean rock is washed and open graded, so it drains. It backfills subdrains, drainage tile, pipe bedding and retaining walls.

Washed sand beds and levels under slabs and pavers, and it works as sand fill where a clean, free draining grade is wanted.
