Bulk Aggregates for Patios in Colfax, IA

If you are planning a patio, a paver walk or a shed pad, gravel and aggregate delivery in Colfax, IA starts with the material under the surface. Iowa Rock Supply sells Class A roadstone, the crushed limestone base course with the fines left in, along with the sands and clean stone that finish the job.

This is Southern Iowa Drift Plain ground, where loess sits over old till and a gummy clay paleosol below that refuses water. Plan the base around that clay and the flatwork stays put.

Ground and Conditions in Colfax

A thin base over clay is where patios and walks go wrong here. The clay subsoil does not take water, so it perches, then spring rain on saturated ground softens the subgrade under the bedding layer.

Edges settle, pavers rock, and joints open.

The fix is a compacted base built thick enough to spread the load, with a drainage layer where water has nowhere to go. Across the Southern Iowa Drift Plain the ground is steeply rolling and drains at the surface, but drives and pads still go soft at the bottom of a grade.

Erosion shapes the work too. Streams cut deep and hillslopes carry fine rills, so slope work and culvert outlets get armored rather than left bare.

The working season here is the longest in the state, though clay has to dry before anything compacts, and a wet spring pushes base work back.

Freeze and thaw works on gravel drives and lanes every spring. Frost depth in Iowa commonly runs about 42 inches, and the building official sets footing depth for structures.

Materials for Colfax Projects

Flatwork lives on its bedding. Start with Class A Roadstone, the 3/4 inch crushed limestone base course with fines left in so it binds and compacts under a patio, walk or pad.

Above that base, Limestone Screenings are the fines that bed pavers and flagstone and fill the joints. Washed Sand does the same job under slabs and pavers, bedding and leveling where a clean, free draining grade is wanted.

Where water has to move, Clean Rock is washed and open graded, so it goes in subdrains, pipe bedding and backfill behind retaining walls. 3/8" Crushed Stone is the washed chips Iowa quarries sell for paver joints and fine drainage.

Rounding out a site: Top Soil for lawn repair, grading and bed prep, and Shredded Mulch for beds and tree rings. One inch roadstone goes under a finer surface course on a new drive or a lane carrying heavy equipment.
