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







Colebrook sits in Coos County, where about 197 days a year drop below 32F. That long freeze season means the ground shifts with every thaw, so a solid base under any gravel or rock surface is more than a convenience. Property owners across the county use tons of gravel and rock each year for driveways, paths, patios, and drainage work.
Whether you are shaping a new driveway, resurfacing a path, or controlling runoff along a slope, the choice between gravel and rock comes down to how the material handles weight, water, and movement. This page lays out what to order in Colebrook and why local conditions matter.
The sizes here range from small pea gravel up to 4-inch river rock. Each one suits a different job. The table below lists every option, what it does best, and a quick note on how it behaves.
| Product | Best for | Note |
|---|---|---|
| 3/8" Natural Pea Gravel | Play areas, patios | Rounded and smooth, easy underfoot |
| River Rock | Beds, borders, dry creek beds | Smooth stones that stay put in decorative settings |
| 2-4" River Rock | Larger decorative cover and erosion control | Heavy enough to hold against moderate runoff |
| Drain Rock | French drains and dry wells | Angular, washed stone that lets water pass through |
| Decomposed Granite | Paths and patios that compact firm | Packs into a hard surface with a natural look |
| Crusher Run | Compacting base under everything | Contains fines that lock the stone together |
| Road Base | Lanes and pads that carry trucks | Designed for heavy loads and repeated traffic |
Every project starts with a problem to fix. Choose the product that matches your goal from the table below.
| Project | What to order | Depth or note |
|---|---|---|
| Erosion control on a slope | 2-4" River Rock | 4 to 6 inches deep for stability |
| Path that stays firm | Decomposed Granite | 3 to 4 inches compacted, with a base |
| Dry creek bed | River Rock | 2 to 3 inches deep over landscape fabric |
| Landscape beds | 3/8" Natural Pea Gravel | 2 inches is enough for most beds |
| French drain | Drain Rock | Fill the trench 8 to 12 inches deep |
Colebrook gets about 43 inches of precipitation a year. That moisture means you need good drainage under any surface that will hold traffic. The soils mapped in the Colebrook area are commonly moderately well drained, which in practice means more base stone may be needed under the top layer than in a sandier area. Soils in hydrologic group C take water in slowly and shed a fair amount across the surface, so a deeper drainage layer under patios or driveways earns its place.
Snowfall here averages about 111 inches a year. Plowing a gravel or rock surface repeatedly can push the loose material aside and leave ruts. Using a compacted base like crusher run or road base helps the top layer stay in place through the winter. Ground that freezes deep moves as it thaws, which is why the base layer matters more here than the top layer. A proper base below the frost line or at least a thick compacted layer reduces the shifting that can crack patios or buckle paths.
Freezing happens on roughly 197 days a year. That long cold window shortens the working season for digging and grading, so scheduling delivery onto firm, dry ground is important. About 96 days a year bring at least a tenth of an inch of rain, further narrowing the best days to place a load.
Gravel and rock are sold by the ton. To figure out the weight you need, measure the length and width of the area and decide on a depth. Multiply them to get cubic feet, then convert to tons based on the material's density. You can use our material calculators to do that conversion quickly and get a number for checkout.
Ordering is simple. You pick your product and quantity online, enter your ZIP code for a delivered price, and choose a delivery window: morning from 7 am to 12 pm or afternoon from 12 pm to 5 pm.

Gravel and rock work alongside other bulk materials for a complete job. Here are materials that solve the same site issues or complement the surface layer.
Yes. Colebrook receives about 43 inches of precipitation a year, which means moisture management matters. A well-drained base layer such as crusher run or drain rock helps prevent settling and washout under the surface material.
Yes. With roughly 197 freezing days each year, the ground moves as it freezes and thaws. A thicker compacted base layer underneath the top gravel or rock reduces frost heave and keeps the surface level through the winter.
The size depends on the use. Small pea gravel (3/8 inch) works for patios and play areas. Medium river rock (1 to 2 inch) suits decorative beds and dry creeks. Larger rock (2 to 4 inch) handles erosion control and heavy flow. For a firm base, use crusher run or road base with fines.
