Questions New York Buyers Ask Before a Bulk Order

The order that goes wrong most often here is the one placed for a single material when the job needed two: clean stone spread where a compacting base was wanted, or Item 4 tipped into a trench that needed water to move through it. Fines are the difference, and almost everything below comes back to them, to the depth the frost argues for, and to what the ground underneath is doing. The questions run from the ones that cause wrong orders through to cutting a drive that will hold.

Slope and fines: the two that cause the most wrong orders

How do I stop gravel washing off a slope?

Size and shape do most of the work. Rounded stone like pea gravel or river rock rolls; angular crushed stone keys together and stays put far better on a grade. On a Hudson Valley or Catskill hillside, where heavy rain runs off fast and creeks rise quickly, the surface also needs somewhere for water to go: a cross-fall of roughly a quarter inch per foot, a shallow ditch or swale at the uphill side, and edging or a timber to hold the toe. For a steep bank rather than a path, the answer is not gravel at all but RipRap placed over fabric in a proper layer. Where a drive climbs, expect to drag material back uphill once a year after the spring runoff.

Item 4 and #2 stone both look like gray rock in the pile. Which one goes under a French drain?

Clean stone has been washed or screened so the dust and small particles are gone. Water runs straight through it, and it never really compacts, which is exactly what a French drain, a septic bed or pipe bedding wants. Material with fines keeps that dust, and under a compactor the fines fill the gaps between the larger pieces and lock the layer solid. Item 4, crusher run and stone dust are the ones with fines; the washed grades listed as 3/4 inch crushed stone, #57 and drain rock are the clean ones. Swapping them gives you either a drain that silts up or a surface that never firms.

Depth, and what is left in the pile afterwards

Does an equipment trailer on the lane change the Item 4 section?

It does, and the ground underneath moves it further. A lane taking loaded trucks, equipment trailers or a delivery truck needs a thicker compacted section than a single-car drive over sound ground, placed in lifts rather than one deep dump so each layer can actually be compacted. Soft clay valley ground, thawing lake-plain soil and anything on Tug Hill push you deeper again whatever the vehicle. There is no published depth figure on this site to hand you, so take the guidance on the product page as the starting point, add depth for wet ground and heavy vehicles, and get a designed figure where the lane is genuinely load bearing. Frost reaches about 4 feet down across most of the state, with your building department setting the exact footing depth, so no gravel base sits below it; keeping water out of the layer is what stops a thin lift heaving every spring.

Is it worth keeping material that is left over?

Usually, and it depends on the type. Clean stone keeps indefinitely and is worth having for a washout or a soft spot. Item 4 and crusher run keep well too, though a small pile left uncovered through a New York winter will freeze solid and take some breaking up in March. Topsoil and garden soil go weedy if left open; cover them. Mulch is fine to hold over for a season. Keep leftovers on a tarp rather than on lawn or bare soil, and put them somewhere the plow will not find them.

Item 4, #2 stone and picking the right product page

The yard calls it Item 4 but the catalogue says something else. Which do I order?

Item 4 is the New York trade name for compacting subbase stone and is what you want for a drive, pad or patio base; it sits under the road base product here. #2 stone and #1 stone are the local numbers for the washed crushed grades, and stone dust is screenings, so take the size for each from its own product page rather than from the number. Where a name is ambiguous, ignore it and read the size and grading on the product page against what your job or your plan sheet calls for. New York material is specified under NYSDOT Section 304 for subbase and Table 703-4 for stone sizes, which is how a spec describes it rather than anything this storefront certifies.

Two layers on one drive: which gets measured and bought first?

Treat them as two orders that travel together. Work out the finished level first, then subtract the surface course and the base course to get the depth you need to excavate to. Size each layer in its own calculator, because the depths and the weights differ, then put both products in one order so they arrive on the same delivery. Spread and compact the base, check it is flat and draining, then bring in the top course.

What should I do if the site is soft or wet?

Wait, if the calendar allows it. Rolling stone into ground that is still pumping water gives you a base that has to come out again. Silt and clay valley floors along the Hudson and the Mohawk, flat lake-plain ground inland of the lakes, and the dense upland subsoils of the Southern Tier all stay soft well after the surface looks dry. If waiting is not possible, a separation fabric under the stone, sourced locally since it is not a catalogue item here, stops the base working down into the soft material, and a deeper lift placed in stages does better than one thick dump. The same applies to the truck: soft ground at the drop point is a problem before the material is even off it.

The layers that survive a spring thaw

Cutting a drive to survive the spring thaw: what sits at each level, bottom to top?

From the bottom: strip the sod and topsoil and cut to the full depth of everything going in. Set a crown or cross-fall so meltwater runs off. Lay separation fabric if the subgrade is soft clay or silt. Place the base, Item 4 or crusher run, compacted in lifts, thicker where heavier vehicles will use it. Then the surface course of driveway gravel over the top. Skipping the top course leaves the fines exposed, and the first spring thaw will find them.

Three things are answered better a page over. Tons against yards, the weight behind a volume and the tonnage arithmetic are in the calculators. Access, the checkout fields and the tipped pile belong to the delivery page, and it settles what most people ask next: a short order is topped up by buying the balance separately, not by reopening a load already on the schedule. The refund and order-change policy is published with it. Still stuck between two products? Send the measurements, the ZIP and a line about the ground through the contact page, or start from the full catalogue.
