Gravel and Aggregate Delivery in Griswold, IA

Gravel and aggregate delivery in Griswold, IA runs on the weather. Iowa Rock Supply sells Class A roadstone, gravel, sand and topsoil for drives, pads, lanes and beds across Cass County.

Clay ground here needs to dry before anything gets compacted, so a wet spring pushes base work back several weeks. Order when the ground is ready.

Materials for Griswold Projects

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

Order it at Class A Roadstone.

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

See 1 Inch Roadstone.

To top an existing drive or lane that has thinned out, driveway gravel goes over a compacted roadstone base. It is the surface layer, not the base.

See Driveway Gravel.

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

Order it at Clean Rock.

Limestone screenings bed pavers and flagstone and fill the joints. They also dress the top of a compacted roadstone base.

Order them at Limestone Screenings.

Sand, soil and decorative stone round out a load. Washed sand beds and levels under slabs and pavers, while black dirt repairs lawns and preps beds.

See Washed Sand and Top Soil.

Natural Pea Gravel suits walkways, play areas and patio bedding. River rock and large river rock build dry creek beds and borders.

Ground and Conditions in Griswold

Across the Southern Iowa Drift Plain, rain and snowmelt are the whole story. Old till sits under a windblown loess mantle, with a thick gummy grey clay beneath it that water will not move through.

So water perches, runs off and leaves drives soft at the bottom of a grade. Spring rain on saturated clay is the worst of it.

This is the state's most eroded landscape. Streams cut deep, hillslopes carry fine rills, and gully and stream bank erosion after heavy rain is why rock goes on slopes and at outlets.

That ground shapes material choice. Clean rock drains where fines would hold water, and riprap armors a bank or a culvert outlet against spring runoff.

See Riprap.

Cold winters bring repeated freeze and thaw, enough to heave gravel drives and lanes every spring. Footing depth is set by the local building official.

The working season here is the longest in the state, but clay has to dry before you compact over it. Plan base work around that window, not against it.
