Crushed Gravel ordered online by the ton. A dump truck delivers to your Mackay address and unloads right where you point.
Crushed gravel is a common choice for driveways, base layers, and fill in Custer County. Mackay sits in a mountain valley where the ground freezes deep and stays frozen for months.
That freeze-thaw cycle makes the base under any gravel surface critical. Custer County permitted about 49 single-family homes in 2024, and many of those lots will need a solid foundation of crushed gravel before anything else goes in.
Crushed gravel ranges from fine dust to large stones. The right size depends on what you are building and how much weight the surface will carry.
| Size | Best for | Note |
|---|---|---|
| 3/8" Crushed Gravel | Fine compacting layer | Ideal as a top dressing or between larger stone. |
| 3/4" Crushed Gravel | The workhorse size for base and drives | Compacts well and handles cars and light trucks. |
| 1" - 1 1/2" Crushed Gravel | Structural base under heavy loads | Used under concrete slabs or commercial lots. |
| 1 1/2" Crushed Gravel | First lift over soft subgrade | Good for bridging soft ground in wet areas. |
| 2"-3" Crushed Gravel | Mud control and deep fill | Largest size, used for utility trenches or stabilising slopes. |
Match the stone size to the problem you are solving. A trench backfill needs a coarse stone that drains freely, while a driveway surface needs a smaller, angular stone that locks together under traffic.
| Project | What to order | Depth or note |
|---|---|---|
| Trench backfill | 2"-3" Crushed Gravel | Fill trench to grade, compact in lifts. |
| Soft or muddy subgrade | 1 1/2" Crushed Gravel | First lift to bridge the soft layer. |
| Farm and site access road | 3/4" Crushed Gravel | Best all-round depth is 6 to 8 inches. |
| Compacted base for a shed or pad | 1" - 1 1/2" Crushed Gravel | Minimum 4-inch compacted depth. |
| Shed or slab pad | 3/4" Crushed Gravel | Cover with 3/8" crushed gravel if a smooth finish is needed. |
Ground freezing in this area is deep and long. That means the base layer beneath a driveway or parking area must be thick enough to resist frost heave. Soils mapped in the Mackay area are commonly well drained, which reduces how much base stone is needed under the surface layer. You still need a good depth, but the drainage works in your favor.
The ground around Mackay is in hydrologic group B, meaning it takes water in at a moderate rate. Standard base depth is usually enough to handle rain and snowmelt because the water does not sit on top for long. Hard freezes shape the calendar here, so base work is easier to get right from late spring through fall.
If you are building on a new lot, the natural subgrade might be uneven or have soft spots. The coarse 1 1/2" crushed gravel works well as the first lift over soft subgrade.
Coverage depends on the size of the area and the depth you want. Use the material calculators on the Gravel Monkey site. Enter your length, width, and depth to get a tonnage estimate. For most projects, ordering a little extra is safer than running short.

Crushed gravel works well on its own, but sometimes a complementary material does a better job in a specific spot. Here are materials that pair with crushed gravel for Mackay jobs.
The price depends on the amount you order and your delivery ZIP code. You see the total at checkout before you pay. Gravel Monkey does not publish a per-ton rate to Mackay because the cost varies by source and distance. Use the online calculator to estimate tonnage, then place an order to see the delivered price.
Soils mapped in the Mackay area are commonly well drained, which means you may not need an extra-thick base to manage water. The ground here is in hydrologic group B and takes water in at a moderate rate, so standard base depths are usually sufficient. Deep frost is the bigger concern. Thicker crushed gravel layers help guard against frost heave.
Orders must be placed at least 3 business days before the chosen delivery date. That buffer gives the team time to source and confirm the load. Ordering a week or more ahead is a good idea during busy spring and summer months.
The sizes range from 3/8 inch up to 2 to 3 inches. Smaller stone compacts to a smooth surface, while larger stone provides drainage and structural bulk. The 3/4-inch crushed gravel is the most versatile for driveways and bases. Coarser stone works under heavy loads or over soft ground. Every size has a job it does best.
Ordering crushed gravel does not require a trip to a yard. Gravel Monkey brings it to your Mackay address by dump truck. Visit the Mackay materials page to start an order or use the calculator to figure out how much you need.
