Crushed Stone, Sand and Gravel in Martinsville, NJ

New Jersey Rock Supply handles gravel and aggregate delivery in Martinsville, NJ, with quarry process at the center of most orders. This part of Somerset County sits on silty, clay-rich ground weathered from red shale and sandstone, with rock often only a short way down. That ground decides what you order and how deep you build.

You can buy quarry process, washed stone, sand, topsoil and decorative rock by the ton or the yard, ordered online and dropped at your site.

Materials for Martinsville Projects

Most work here starts with a base, and in New Jersey that base is quarry process, also called QP or 3/4 inch QP, a blend of 3/4 inch stone down to stone dust. It compacts hard and locks together under driveways, parking pads, shed bases and pavers. It is also specified as dense graded aggregate, or DGA.

Above that base you have choices. For a driveway surface, 3/4 inch trap rock is the hard, dark crushed stone New Jersey is known for. For a finer, walkable surface, use 3/8 inch crushed stone or Natural Pea Gravel. Where water has to move, clean stone does the work.

For drainage, #57 Stone and Drain Rock feed French drains, drywells and downspout runs. Stone Dust is the usual setting bed over a QP base for pavers and flagstone. Sand covers brick and block work, slab bedding and play areas. Fill dirt raises grade before any base goes down, and Top Soil finishes the lawn. Decorative beds and dry creek beds take river rock or Natural Pea Gravel.

Ground and Conditions in Martinsville

Start with where the water goes. Tight clay soil and shallow shale take in little rain, so runoff moves fast across Martinsville. Low flats stay soggy, and the Raritan and Millstone rivers and their tributaries rise quickly in big storms.

That shapes your base. A driveway needs a compacted QP layer deep enough to bridge wet, soft clay, and a drainage layer of clean stone beside it to carry water away. Skip the drainage and the base pumps and fails.

Fast runoff off clay soils and shale slopes also cuts into stream banks and bare ground, and exposed red soil washes into streams after heavy rain. Rip rap armors culvert outlets, stream banks and slopes where that flow hits.

Timing matters too. Wet clay ground is slow to dry after winter and long rainy spells, so spring base and grading work often waits for the soil to firm up. Frost reaches about 3 ft under the NJ residential code, so footings and buried work go below that line.

Delivery to Martinsville and the Surrounding Area

Bulk material arrives by dump truck and is tipped where you want it. Have the drop spot clear, reachable, and on firm ground, because a loaded truck on soft clay is a problem for everyone.

Order online and pick your material by the ton or the yard. Size the load to the job: base depth times area gives you volume, and the site converts that to weight for you. Ordering a little over is safer than running short mid-project.

New Jersey Rock Supply delivers across Martinsville and the rest of Somerset County, including Bridgewater, Somerset, Hillsborough, Warren and Franklin Park. Place the order and we will bring it to the site.
