Bulk Aggregates for Drainage in Larchmont, NY

New York Rock Supply handles gravel and aggregate delivery in Larchmont, NY, and most orders here start with item 4. It is the standard New York name for compacting subbase stone, and it goes under driveways, parking pads, patio bases and shed bases. Around Larchmont, clay and silt left by old glacial lakes drain slowly and stay wet after storms, so what you put under a slab or a drive matters.

Materials for Larchmont Projects

Drainage drives most of the material choices here. Washed stone, French drains, drywells and downspout runs all need open, clean stone that lets water move instead of holding it. The list below runs from the coarsest stone to the finest, with what each size is good for.

• RipRap, also called rip rap, armors stream banks, culvert outlets, slopes and shorelines against runoff, waves and ice.
• #4 Crushed Stone is heavy drainage stone for construction entrances and trench bottoms.
• #57 Stone covers drainage, French drains and concrete aggregate. Some New York yards sell this size range as a #1 and #2 blend.
• 3/4" Crushed Stone, sold as #2 stone, handles drainage, septic beds, pipe bedding and backfill.
• Drain Rock is the one to keep on hand for French drains, drywells, foundation drains and downspout runs.
• 3/8" Crushed Stone, sold as #1 stone, works for fine drainage, pipe bedding, walkways and topping over a compacted base.
• Item 4 compacts into a firm base for driveways, parking pads, patio and shed bases.
• Stone Dust, also called screenings, beds pavers, flagstone and patio stone, and finishes fine pathways.

For a French drain or a drywell, the washed sizes do the work. #2 stone and #57 stone both stay open under a drain line, and #1 stone fits tighter pipe bedding. Pair the stone with filter fabric and the drain keeps running instead of silting up.

Where a surface is wanted rather than a drainage layer, Driveway Gravel tops a compacted item 4 base, and Walkway Gravel gives paths a finer, walkable finish. Beds and tree rings take Shredded Mulch, which holds moisture through the summer. Sand and soil round out most orders: Mason Sand for brick and block work and paver joints, Top Soil for lawn and bed prep, and Fill Dirt for raising grade and filling low spots before a base or topsoil goes down.

Delivery to Larchmont and the Surrounding Area

You order online, choose a quantity by the ton or the yard, and size the load with the calculator before checkout. Pick your delivery date at checkout, and a dump truck brings the material to your site. Larchmont sits in Westchester County, and delivery covers the county, including Yonkers, New Rochelle, Mount Vernon, White Plains and Port Chester.

Think about where the truck can drop before you order. A bulk load needs a clear, firm spot where the bed can tip without blocking the street or sinking into soft ground. If your driveway is the drop point, the material lands close to the work and saves moving it twice.

Ground and Conditions in Larchmont

Base and driveway work runs from spring thaw into late fall. Frozen ground stops compaction in winter, and wet clay valley ground can stay soft into spring, so timing a delivery matters as much as the material itself.

Stony glacial till covers the hills and highlands, where ledge rock is often close to the surface. On the valley floors, silt, clay and sand left by old glacial lakes drain slowly and stay wet after storms. Spring snowmelt, ice jams and heavy rain from coastal storms raise the Hudson and its tributaries.

Cold winters bring repeated freezing and thawing, and the silt and clay soils on valley floors are especially prone to frost heave. Frost depth is usually about 4 feet down for footings, and the local building department sets the exact depth. That cycle is why a compacted item 4 base and a clean drainage layer under a drive or patio hold up better than a thin layer of stone over soft ground.
