Landscaping Material Delivered in Irwin, ID

If you are planning gravel and aggregate delivery in Irwin, ID, the first question is usually what to put down. For most ground work here that answer is road mix, the crushed base with the fines left in.

Idaho Rock Supply delivers bulk rock, sand and soil to Irwin and Bonneville County. This page starts with the decorative material: beds, dry creek beds and ground cover.

Delivery to Irwin 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 you check out.

Pick your delivery date at checkout, and a dump truck tips the material on your site in one pile. Irwin sits in Bonneville County, and delivery covers the surrounding area, including Idaho Falls, Iona and Swan Valley.

Bulk loads arrive loose and unloaded in a single pile, so the placement on your property is yours to plan before the truck arrives.

Materials for Irwin Projects

Start with what the space has to do. A decorative bed wants a different rock than a drive or a drain, and the local names below are the ones yards here use.

For beds, borders and dry creek beds, Snake River Rock is the round rock most landscape work here calls for. It is also listed as round rock, and it sits well in a dry creek bed or around a water feature.

Large River Rock is the bigger cobble, usually sold between 2 and 10 inches, for heavier borders, drainage swales and larger dry creek beds. 3/8" Natural Pea Gravel is round and uncrushed, which suits patios, dog runs and play areas where a soft surface matters.

Where you want ground cover that stays put, 3/8 Chip is angular, so the chips knit together on pathways and as a topping over a compacted base. Top Soil goes under any bed you plan to plant, since the native ground here is thin.

For the working surfaces, 3/4 Road Mix is the base course under driveways, parking pads, shop floors and shed slabs. Drain Rock is clean angular rock for french drains, foundation drains, drywells and downspout runs, sold in 3/4 inch, 1 1/2 inch and 2 inch.

Ground and Conditions in Irwin

Across the Central Idaho mountains and high valleys, the soil is thin and coarse over granite, and it weathers down to sandy Stone Screenings. Glacial till and moraine show up around the valley heads, with deep outwash sand and gravel on the valley floors.

That ground drains fast where it is deep. Where the soil is shallow over bedrock, meltwater runs across the surface instead, and a base that was never built for it will not hold.

Spring snowmelt and rain on snow scour creek banks and mountain roads here, and Stone Screenings washes out readily once it is disturbed. A drive cut into bare ground loses its shape over a season.

This is the shortest working season in the state. Snow and frozen ground close out base and paver work from late fall until the ground dries in late spring, so the reliable window runs early summer to early fall.

Long hard mountain winters bring deep snow, deep frost and a heavy spring breakup that softens and ruts gravel roads and drives as the frost comes out. Frost depth figures vary by county and the local building official sets footing depth, so check with yours before you build.
