Limestone Screenings for Pathways in Union, IA

Iowa Rock Supply brings gravel and aggregate delivery in Union, IA for driveways, patios, drainage runs and garden paths. If you are bedding a walkway, Class A roadstone under limestone screenings gives you the base and the finish in one order.

Ground here is loamy glacial till over a pebble band, so a walkway base has to hold shape through spring thaw. That is where screenings earn their place.

Ground and Conditions in Union

Across the Iowan Surface, loamy glacial till sits under a thin, patchy cap of loess. A residual pebble band often shows near the surface, along with large granite and quartzite erratics in the fields.

Stream gradients here are low, so water moves slowly and old wetland pockets still hold it. Limestone aquifers keep the rivers running in dry spells and can push groundwater close to the surface.

A path or walkway with a thin base shows the failure first. The surface ruts, the edges break down, and screenings pump up through the joints after a wet spring.

The fix is a compacted roadstone base built up to a real depth, with a fines-bearing surface course over it. Sheet wash on the long, low slopes and gully cutting where runoff concentrates are the other reason a path needs a firm, level bench.

Work starts once frost is out and the low gradient ground has drained, and runs to the fall freeze. Low spots stay soft well after the uplands are ready to work.

Materials for Union Projects

Fines and screenings do the finish work on paths and walkways. Limestone screenings, sold here as screenings or 3/8 inch minus screenings, bed pavers and flagstone, fill joints, and top dress a compacted roadstone base.

Under that finish you want Class A roadstone. It is the standard Iowa base course: 3/4 inch crushed limestone with the fines left in, so it binds and compacts.

Use it for driveways, parking pads, shed bases and farm lanes.

For a new drive or a lane that carries heavy equipment, 1 inch roadstone is the coarser grade laid under a finer surface course. For a drive that has thinned out, Driveway Gravel tops an existing compacted base.

Where water has to move, clean rock is washed and open graded. It goes into subdrains, drainage tile backfill, pipe bedding and behind retaining walls.

Clean Rock comes as 1 inch clean or 1 1/2 inch clean.

Decorative beds take rounded stone. River rock and large river rock suit dry creek beds and borders, while 3/8" Natural Pea Gravel fits walkways, play areas and patio bedding.
