Order Item 4 and Crushed Stone in Sullivan County, NY

New York Rock Supply brings gravel, stone and aggregate delivery in Sullivan County, NY to driveways, drainage jobs and building pads from Monticello to Livingston Manor. Item 4 is the compacting subbase stone most yards here order first, and it works over the stony, silty glacial till that covers the hills. Around it we stock crushed stone sizes, washed sand, topsoil, mulch and riprap.

Steep hillsides shed heavy rain fast, so what you put down has to move water as well as carry weight. Pick the material by the job, and order it by the ton or the yard.

Ground conditions across Sullivan County

A driveway base that is too thin tells you quickly here. After a wet spring the surface rutts, the edges break down, and soft spots open where water sat in the subgrade. The cause is usually the ground itself, not the stone on top.

Most of the county sits on stony, silty glacial till over layered shale and sandstone. Upland soils often carry a dense subsoil layer that holds water near the surface. Valley floors carry gravel, sand and silt.

That dense layer is why drainage matters as much as thickness. Water trapped under a compacted base softens the till below it, so the stone loses support and pumps.

Frost adds a second round of trouble. Long, cold winters bring repeated freezing and thawing, and wet silty till can heave and turn soft as the frost comes out of the ground in spring. Footings usually go about 4 feet down, and the local building department sets the exact depth.

Work from spring thaw into late fall. Frozen ground stops compaction in winter, and hillside sites and back roads can stay soft and wet into spring.

Materials delivered in Sullivan County

Item 4 is the standard New York name for compacting subbase stone, and it is the material most driveways, parking pads, patio and shed bases start with. New York yards use the trade name. Crushed stone sizes such as 1A. Order Item 4 when you want a base that locks up under a plate compactor or roller and stays put.

Above that base, the choice depends on the surface and the water. Here are the materials we run most often in this county.

For drainage runs, Drain Rock handles French drains, drywells, foundation drains and downspout runs. #4 Crushed Stone suits heavy drainage, construction entrances and trench bottoms, and #67 Stone covers drainage and concrete work at a slightly smaller size. Where a drive just needs a fresh wearing surface over a sound base, Driveway Gravel is the practical pick, and Walkway Gravel gives paths a finer, walkable finish. For beds, borders and dry creek beds, River Rock and Large River Rock do the decorative work, and Shredded Mulch holds moisture in beds and tree rings through the summer.

Delivery across Sullivan County

You order online, choose a quantity by the ton or by the yard, and pick a delivery date at checkout. A dump truck then brings the load to the site and drops it where you want it.

The one part worth slowing down on is quantity. Tons and yards are not the same measure, and the material you pick decides the difference.

We deliver across the county, including Monticello, Rock Hill, Fallsburg, South Fallsburg, Loch Sheldrake, Cochecton, Hurleyville, Bloomingburg, Woodridge and Livingston Manor. On hillside sites and back roads, pick a drop spot the truck can reach and turn around in, and keep it clear of soft ground.

Choosing the right material

Ground next door changes the answer. In Orange County, stony glacial till covers the hills and highlands, where ledge rock is often close to the surface, and many valley floors along the Hudson, Wallkill and Mohawk carry silt, clay and sand left by old glacial lakes.

Ulster County spans more than one zone, so conditions shift from town to town. Where it shares the Southern Tier, Catskills and Finger Lakes hills, the ground is similar to ours and the same materials apply.

Delaware County sits in the same ground zone as Sullivan, with stony, silty glacial till over layered shale and sandstone, dense subsoil on the uplands, and gravel, sand and silt on the valley floors. The ground is similar, so compare typical projects instead: a steep driveway there wants the same compacted Item 4 base and edge drainage a Sullivan County drive does, while a valley-floor pad leans on clean stone for drainage.
