Gravel & Rock ordered online by the ton. A dump truck delivers to your Ankeny address and unloads right where you point.







Polk County properties, from new construction to established homes, regularly order gravel and rock for paths, beds, and foundations. Ankeny gets about 37 inches of precipitation a year, which makes drainage and washout planning an important part of every project.
Whether you are building a patio, a driveway, or a dry creek bed, choosing the right size and type of gravel or rock saves time and rework. The sections below walk through what is available and how to match it to your job.
Gravel and rock come in sizes from pea gravel to four-inch river rock. The right choice depends on whether you need a compacted base, decorative cover, or drainage. Each product has a specific strength. The table lists the choices.
| Product | Best For | Note |
|---|---|---|
| 3/8" Natural Pea Gravel | Play areas, patios | Rounded and smooth surface that is comfortable underfoot. |
| River Rock | Beds, borders, dry creek beds | Natural look with varied sizes for a soft, decorative finish. |
| 2-4" River Rock | Larger decorative cover and erosion control | Stays in place on slopes and handles runoff well. |
| Drain Rock | French drains and dry wells | Clean, angular stone that allows water to move through freely. |
| Decomposed Granite | Paths and patios that compact firm | Compacts to a solid, walkable surface that resists weeds. |
| Crusher Run | Compacting base under everything | Angular stone and fines that lock together tightly. |
| Road Base | Lanes and pads that carry trucks | Heavy-duty mix designed for vehicle traffic. |
Each project needs a specific size and type. The table below matches common Ankeny jobs to the gravel and rock that works best for them.
| Project | What to Order | Depth or Note |
|---|---|---|
| Landscape beds | River Rock | 2 to 3 inches deep, covers bare soil and suppresses weeds. |
| Path that stays firm | Decomposed Granite | 3 to 4 inches after compaction, provides a stable walking surface. |
| French drain | Drain Rock | 12 to 18 inches deep in the trench, ensures water flows away. |
| Dry creek bed | River Rock | 4 to 6 inches deep, mimics a natural streambed. |
| Erosion control on a slope | 2-4" River Rock | 4 to 6 inches deep, the large size resists movement in heavy rain. |
Ankeny sees about 147 days a year when the temperature drops below freezing. That long freeze season means the ground freezes deep, and the freeze-thaw cycle puts stress on any gravel surface. The consequence is that how you prepare the base matters as much as what you put on top.
Snowfall averages about 33 inches a year. Plowing can disturb a loose top layer, so a stable surface is important. Ground that freezes deep moves as it thaws, which is why the base layer matters more here than the top layer. Soils mapped in the Ankeny area are commonly somewhat poorly drained. That means more base stone may be needed under the surface layer to improve drainage and prevent settling.
The ground around Ankeny falls into dual hydrologic group C/D. Where the soil is drained, it takes water in slowly and sheds a fair amount across the surface. Where it is not drained, water runs across the surface almost entirely. This makes drainage and a deeper base more important here than elsewhere. The exact condition depends on your specific lot's drainage, but planning for adequate base material is a safe step.
To figure out how many tons you need, measure the area's length, width, and desired depth in feet. Multiply them to get cubic feet, then convert to tons. Gravel Monkey's material calculators on the calculators page can do that math for you. Simply enter your dimensions and the calculator gives a tonnage estimate.

Gravel and rock often work alongside other bulk materials. Consider adding one of these to your order.
Yes. Ankeny has about 147 freezing days per year, which means deep frost. A well-compacted base like crusher run or road base helps prevent heaving and settlement.
Yes. With about 37 inches of annual precipitation, drainage is a key factor. Choosing drain rock for sub-surface projects and a base layer that handles moisture will extend the life of your gravel surface.
The size depends on the project. For paths that need to be firm and walkable, decomposed granite or crusher run works well. For decorative beds, river rock or pea gravel. For drainage, drain rock. For erosion control, larger river rock.
