Materials for Cresskill Projects

A Cresskill patio depends on its bedding. Under pavers and flatwork you build a compacted quarry process base, then set the pavers on stone dust. Skip either layer and the surface rocks, heaves and drops within a season or two.

Quarry process, also called QP, 3/4 inch QP or DGA, is the standard New Jersey base. It blends 3/4 inch stone down to stone dust, so it compacts into a tight, binding mat that sheds water instead of holding it.

Stone dust, also called screenings, is the setting bed. Spread it thin and screed it flat for paver and flagstone bedding, joint fill and firm path surfaces. It locks the pavers without letting them sink.

Top the finished patio with clean stone or Natural Pea Gravel where you want drainage at the edge. Trap rock is the hard, dark crushed stone New Jersey is known for, sold here as 3/4 inch trap rock.

Washed sand and mason sand handle the wet work. Mason sand suits brick and block work and paver joints; washed sand levels and beds under slabs. Pair them with a QP base and the patio drains from the bottom up.

Ground and Conditions in Cresskill

A thin base shows itself fast here. Red shale and sandstone bedrock sits under compact glacial till, sand and gravel, and silt and clay left by old glacial lakes. Clay holds water, so an underbuilt patio pumps, settles and cracks at the corners.

Adding more on top will not help; a deeper base with drainage will. Excavate to full depth, compact the quarry process in lifts, and give the base somewhere to shed water. Add a clean stone drainage layer where the subgrade stays wet.

Freeze-thaw runs every winter. Frost depth is 3 ft under the NJ residential code, and ground that stays saturated will not compact. Build from spring into late fall and cover open subgrade before storms.

Heavy rain scours stream banks and channels in the river valleys, and runoff cuts into steep slopes and bare soil. Pumped sump lines, downspouts and slope edges call for rip rap or clean stone, not fill.

Delivery to Cresskill and the Surrounding Area

Order online and choose your quantity in tons or cubic yards. Bulk material is sold by weight or by volume, so know which one your numbers are in before you check out.

To estimate, take length times width times depth in feet, divide by 27 for cubic yards, then convert to tons with the material's weight. A thick patio base needs far more material than a thin layer over the same area. Use the on-site calculator to skip the math.
