Crushed Stone, Sand and Gravel in Trenton, NJ

For gravel and aggregate delivery in Trenton, NJ, New Jersey Rock Supply stocks the materials this market actually asks for by name. Quarry process, or QP, is the base most driveways and parking pads here start with. Ground in this part of Mercer County runs to layered sand, silt and clay, so a compacted base matters more than it would on straight sand. Work runs most of the year, and scheduling around wet spells saves you a torn-up drive.

Materials for Trenton Projects

Quarry process is the standard New Jersey base material. It blends 3/4 inch stone down to stone dust, and it locks up hard under a plate compactor or a roller. For a driveway, spread it in lifts and compact each one before the next. Order QP (Quarry Process) for driveways, shed bases and the base under pavers. Some suppliers sell the same blend as crusher run, so ask for Crusher Run if that is the name on your plans.

Once the base is tight, top it. 3/4" Trap Rock is the hard, dark crushed stone New Jersey is known for, and it wears well on a drive. For a finer, easier-to-walk surface, Driveway Gravel is the practical choice on an existing drive.

Washed stone handles water. #57 Stone is the usual pick for French drains, drainage behind retaining walls and concrete aggregate, and Drain Rock covers drywells, foundation drains and downspout runs.

Sand and soil finish the job. Stone Dust is the setting bed over a QP base for pavers and flagstone. Mason Sand handles brick and block work, and Top Soil rebuilds lawns and beds after grading.

Ground and Conditions in Trenton

Trenton sits on the Inner Coastal Plain, where layered sand, silt and clay hold water better than the sands farther southeast. Flat ground and clay layers slow drainage in low spots. After a summer storm or a nor'easter, water backs up creeks running to the Delaware River, and it has to go somewhere on your lot.

That is why base depth and drainage matter here. Cut the base thick enough to bridge the soft clay underneath, then compact it in lifts. Put a drainage layer under the edges so water leaves instead of sitting in the subgrade. For a driveway, plan a solid layer of compacted quarry process, and more where the ground stays wet.

Freeze-thaw comes every winter, but it is milder here than in the northern hills. Mercer County frost depth runs to 3 feet under the residential code, so footings and buried drains need to sit below that line. Mid-winter and long wet spells slow base and grading work. Most of the year, though, the ground is workable.

Runoff also scours creek banks and bare slopes in downpours. If your property touches a waterway, RipRap armors the bank against that flow.

Delivery to Trenton and the Surrounding Area

Order online and pick your material, then choose a quantity by the ton or the cubic yard. A driveway base usually runs by the ton, while soil and mulch are easier to figure by the yard. If you know your square footage and depth, you can size the load before you check out.

Bulk material arrives on a dump truck and gets tipped where you want it. Have the drop spot clear and reachable, and keep cars, bins and low wires out of the path. Tell us at checkout if the truck needs to stay on pavement, and we can work from the street.

We deliver across Trenton and Mercer County, including Princeton, Robbinsville, Hightstown, Pennington and Princeton Junction.
