How do I keep a gravel driveway from rutting during spring in Post Falls?

Start by directing water away from the drive instead of allowing it to collect in the wheel paths. Add and compact 3/4 Road Mix in controlled lifts where the base is thin or soft. Regrade the top surface to maintain a crown, then compact again after spreading fresh material.

How deep should a Kootenai County gravel driveway base be with the 30-inch frost guide?

The 30-inch figure is Idaho's statewide frost-depth guide, not a required driveway-base depth. For a vehicle driveway, 6 to 8 inches of compacted base is a useful planning range, with more depth needed over weak or wet ground. Confirm frost-related building requirements with the local building department when the project includes structures or footings.

Which base stone works under pavers or a shed pad here?

Use 3/4 Road Mix for a paver or shed base because its blended fines compact into a stable layer. Ask for 3/4 minus, road mix or crushed base if that is the name used in your plans. Compact the material in lifts and grade the finished base so water drains away from the structure.

What ZIP code should I use for a Post Falls delivery location?

Post Falls uses ZIP code 83854. Enter the full street address and describe the access route and intended dump spot. That information helps match the delivery plan to the conditions at the property.

Bulk materials for Post Falls jobs

For a driveway, shed pad or paver base, use a compactable material with fines that lock together. For drainage behind a retaining wall or around a line, use clean rock with open spaces between pieces. Decorative rock, sand and gravel each have their own purpose, so keep base material separate from finish material when ordering.

3/4 Road Mix is also called 3/4 minus, road mix or crushed base. It aligns with ITD Section 703 3/4 inch aggregate base and is the material to consider where a firm, compacted surface is needed. Drain Rock, also called 3/4 clean or washed rock, belongs in applications where water needs an open path through the rock. Snake River Rock, known as river rock or round rock, is better kept for visible finish areas instead of a compacted base.

Ground, frost and drainage for Kootenai County work

Plan the base after looking at the soil, slope and where water will leave the finished area. Idaho ground conditions vary substantially. Alluvial gravel in the Treasure Valley sheds water readily, while deep loess in the Palouse and clay in Idaho's Panhandle retain water. Check the soil at the actual job before deciding on base thickness and drainage rock.

The statewide frost-depth guide is 30 inches. Confirm local requirements with the local building department before setting footings, placing structural pads or building work that needs frost protection. A gravel driveway base is not a footing, but frost and wet subgrade still matter because they affect movement and rutting.

For light pedestrian work, a compacted base around 4 to 6 inches is a practical starting range. Driveways and vehicle pads commonly call for 6 to 8 inches or more, depending on soil condition and vehicle use. Spread 3/4 Road Mix in lifts, wet it lightly as needed and compact each lift before adding the next. Keep the finished surface crowned or sloped so water does not stand in the wheel tracks.
