Gravel, Stone and Soil for Coos County, NH
New Hampshire Rock Supply handles gravel, stone and aggregate delivery in Coos County, NH. Crushed gravel, the standard base under North Country drives and parking pads, comes by the dump-truck load. So does crusher run, stone dust, pea stone, drain rock, loam and sand.
Ground here is stony glacial till and ledge in the hills, with sand and gravel in the main river valleys. That means a compacting base and a real drainage layer matter more here than they do on flat, sandy ground.
Materials Delivered in Coos County
Order by the ton and the load arrives on your site. Here are the materials for work in this county, grouped by family.
Crushed gravel is the common base course under Coos County drives and roads. It is a graded mix of stone and fines that packs down hard under a roller or a plate compactor. Item 304.2 is the gravel counterpart. Order it for a new drive build, a parking pad, a shed or garage base, or to rebuild a rutted drive after mud season. It is also the layer that sits under crusher run or driveway gravel when you want a top course that looks finished.
Washed stone covers the drainage side. 3/4" Crushed Stone, #57 Stone and #4 Crushed Stone go into French drains, curtain drains and construction entrances, where you want water to pass through instead of ponding. Finish flatwork joints and tight bedding with #89 Crushed Stone.
Sand, soil and decorative stone round out the order. Mason Sand beds brick and block and fills paver joints. Garden Soil and screened loam feed raised beds and lawns, while River Rock and Shredded Mulch handle bed borders and tree rings.
Ground Conditions Across Coos County
Start with the water. Snowmelt and a long mud season are the two forces that shape base work here, because thawed soil holds water above ground that is still frozen underneath. River ice jams add flooding on low ground in spring.
Frost runs deep in the North Country, and frost heaves lift gravel drives and roads every spring. Frost depth is set by the town building official, so confirm the local figure, as it can be deeper than the 4 feet common in southern towns. Build the base deeper than you would down south and compact it in lifts.
Erosion follows the same water. Spring runoff and ice jams scour river banks, and heavy rain washes out gravel roads and culverts on steep ground. RipRap on a bank, a culvert outlet or a lakeshore holds that edge in place.
Timing matters too. The colder climate leaves a shorter working season than in the south, so base, driveway and paver work fits between a late mud season and the fall freeze.

Sizing a load is simple. Enter the area and the depth you want in the calculator, and it works out the tons or yards. A driveway base is usually figured by length times width times depth, then converted by material weight.
Have the drop spot ready before the truck arrives. Clear overhead branches and wires, keep the path firm enough for a loaded truck, and pick a spot close to the work so you are not moving material twice. A tarp or a hard pad keeps the pile clean if it will sit a while.
Choosing the Right Material
The right material shifts as the ground shifts. In Grafton County the ground spans more than one zone, from the White Mountains through the Lakes Region to the Upper Valley. That mix means some jobs there want the same compacting crushed gravel base, while valley and lake lots often want more washed stone for drainage. Coos County ground is more uniform: stony till and ledge in the hills, sand and gravel in the river valleys.
Within Coos County the choice follows the project. A new drive on ledge wants crushed gravel first, then a topping. A low, wet lot wants drain rock and #57 stone before anything gets surfaced. Flatwork wants stone dust. Beds and lawns want screened loam or garden soil on top of what is already there.
