Mason Sand for Patios in Greeley, IA

Iowa Rock Supply brings gravel and aggregate delivery in Greeley, IA, with Class A roadstone as the base course most drives and pads start from. This is the driftless northeast, where thin soil sits over limestone and water finds its way down through the rock instead of running off.

Your flatwork and bedding material comes from the same yard. Order online and a truck tips it on site.

Ground and Conditions in Greeley

Across the Paleozoic Plateau, the driftless northeast, soil is thin over limestone, dolomite, sandstone and shale. Bedrock is shallow on the ridgetops and exposed in valley walls, and the loess cover is patchy.

That matters most under a patio or a walkway. A base that is thin or poorly drained shows the failure first: pavers rock, joints open, and a slab edge settles after a wet spring.

The fix is a compacted roadstone base that carries the load, with the right bedding layer above it. On the Paleozoic Plateau, the driftless northeast side, water also disappears into sinkholes and fractures rather than sitting on the surface.

Steep valley sides send runoff down fast after a storm.

Work fits between the spring thaw and the fall freeze. Cold winters in deep, shaded valleys work frost into fractured rock and thin soil, and spring breaks up surfaces on steep lanes.

Frost depth is commonly 42 inches, the figure Dubuque publishes; the local building official sets footing depth.

Materials for Greeley Projects

Bedding under pavers and flatwork is where the wrong material shows up fastest. Limestone screenings, also called screenings or 3/8 inch minus screenings, are the fines left over from crushing.

Limestone Screenings bed pavers and flagstone, fill joints, and top dress a compacted base.

Washed sand and mason sand both work under flatwork and pavers, and they are not the same thing. Washed Sand beds and levels slabs, pavers and sand fill where a clean, free draining grade is wanted.

Mason Sand goes into brick and block mortar, paver joints, play sand and horse arena footing.

Everything above sits on a base. Class A roadstone, also called roadstone, 3/4 inch roadstone or road rock, is the standard Iowa base course: crushed limestone with the fines left in, so it binds and compacts.

Class A Roadstone carries driveways, parking pads, shed bases and farm lanes.

For a new drive, a soft spot, or a lane that carries heavy equipment, step up to the coarser grade. 1 Inch Roadstone (1 inch minus, 1 inch road rock) lays under a finer surface course.

Clean rock, also called clean stone, 1 inch clean or 1 1/2 inch clean, is washed and open graded so water moves straight through. Clean Rock handles subdrains, drainage tile backfill, pipe bedding, septic rock and backfill behind retaining walls.

Round stone comes out of the Missouri and Mississippi valleys. River Rock (washed river gravel) covers decorative beds, borders and dry creek beds, and Natural Pea Gravel, which Iowa calls Natural Pea Gravel rather than pea stone, suits walkways and play areas.
