How deep should a Canyon County driveway base be with Idaho's frost guide?

Idaho's statewide guide lists a 30-inch frost depth, but that does not set one base depth for every driveway. Build the base for the vehicle load, soil condition and water movement at the site. Compact 3/4 Road Mix in lifts, and confirm structural requirements with the local building department.

Why are Nampa gravel orders measured in tons instead of cubic yards?

Cubic yards measure volume, while tons measure weight. Stone products have different weights because particle size, moisture and material type vary. Use the calculator to enter length, width and depth, then review the estimated tonnage before placing an order.

What is the difference between 3/4 Road Mix and Drain Rock?

3/4 Road Mix follows ITD Section 703 3/4 inch aggregate base and contains fines for compaction. Drain Rock, also called 3/4 clean or washed rock, has open spaces between pieces for drainage. Use the compacted base under support areas and the clean material where drainage is part of the plan.

Which ZIP codes are included for delivery planning in Nampa?

The listed ZIP codes are 83651, 83686 and 83687. Enter the delivery address when ordering so the site location and material quantity are tied to the correct project.

Bulk Gravel and Stone Delivery in Nampa, Idaho

Nampa is a large city in Canyon County. Patios, paver walks and shed pads all depend on the work below the finished surface, starting with a firm base and the right bedding layer. Idaho Rock Supply provides bulk material ordering for projects that need gravel, stone, sand or soil delivered on a scheduled date.

Materials for Nampa base, drainage and finish work

For a compacted foundation below a patio, paver area or shed pad, use 3/4 Road Mix, also called 3/4 minus, road mix or crushed base. It includes fines that lock the aggregate together during compaction. Drain Rock is clean stone for drainage zones where water needs open spaces to move through. Snake River Rock and Natural Pea Gravel fit finish areas where a rounded stone surface is wanted, while Topsoil is used to build up planting areas after hardscape work is complete.

Set 3/4 Road Mix in lifts rather than placing the full depth at once. Spread each lift, add moisture if needed for compaction, then compact before adding the next layer. For pavers, place the compacted base first and keep the bedding layer thin and even. Mason sand is used for bedding when the project calls for sand below pavers.

Ground, frost and drainage planning in Canyon County

Idaho's statewide frost-depth guide is 30 inches. That figure is a statewide guide, not a site-specific design depth, so confirm footing, utility and structural requirements with the local building department. A gravel base depth for a patio, walk or shed pad depends on the load, existing soil and drainage plan, with many light-use projects built with several inches of compacted base.

Ground conditions matter before choosing material depth. In Idaho, alluvial gravel in the Treasure Valley drains readily, while deep loess in the Palouse and clay in the Panhandle hold water longer. Check the actual job area before sizing the base, especially where irrigation, downspouts or low spots send water toward the work.

Use Drain Rock where a project needs a free-draining stone layer. Keep it separate from soil where the design calls for separation, and provide a route for collected water to leave the area. A dense base such as 3/4 Road Mix is for support and compaction, while clean stone is for drainage space.
