Order Gravel, Stone and Soil in Holland, IA

Iowa Rock Supply brings gravel and aggregate delivery in Holland, IA to driveways, pads and farm lanes. Class A roadstone is the crushed limestone base course this part of Iowa builds on.

The ground here is loamy glacial till, planed down and covered with a thin, patchy layer of loess. That cover sits over a pebble band, and it moves when water gets under it.

Delivery to Holland and the Surrounding Area

You order online and pick a quantity by the ton or by the yard. Each product page has a calculator if you want to size the load before checkout.

Then you choose a delivery date and a dump truck tips the material on site.

Holland sits in Grundy County, and delivery covers the surrounding area, including Grundy Center, Reinbeck, Dike, Conrad and Wellsburg. The truck leaves one pile where it stops.

Have the spot clear before it arrives.

Materials for Holland Projects

Raising grade and building pads is the work that decides how everything above it performs. Fill goes down first, then a compacted base, then the surface you actually see and use.

For raising low ground or backfilling before a base course, use Fill Dirt. It brings ground up to grade so the layers above it have something solid to sit on.

For a driveway, a parking pad, a shed base or a farm lane, use Class A Roadstone. This is the 3/4 inch crushed limestone base course with the fines left in, so it binds and compacts.

Where a new drive crosses a soft spot, or a lane carries heavy equipment, start with 1 Inch Roadstone. It is the coarser grade, laid under a finer surface course.

For a patio or a walkway, bed the pavers on Limestone Screenings. The fines fill joints and give you a fine top dressing over a compacted roadstone base.

For a drain, a culvert outlet or a retaining wall, use Clean Rock. It is washed and open graded, so water moves straight through it.

Ground and Conditions in Holland

That loamy till and patchy loess cover is the reason a base gets built right or fails early. Loess loses strength fast once water reaches it, and the pebble band near the surface gives water a path.

Across the Iowan Surface, drainage networks are established but stream gradients are low. Water moves slowly, and low pockets hold it well into spring.

Limestone aquifers can also put groundwater close to the surface.

Sheet wash on the long, low slopes and gully cutting where runoff concentrates are the erosion patterns to plan around. Bank scour shows up after heavy rain and thaw.

Work starts once frost is out and the low ground has drained, and runs to the fall freeze. Low spots stay soft well after the uplands are ready, so a pad built too early can pump and rut.

Hard northern Iowa winters bring repeated freeze-thaw that lifts gravel drives, walks and slabs each spring. Frost depth is commonly 42 inches, and the local building official sets footing depth.
