What is the difference between crushed stone and Natural Pea Gravel?

Crushed stone has angular, broken faces because it is mechanically crushed, so the pieces lock together and compact. Natural Pea Gravel is rounded natural stone, usually about 3/8 inch, so it stays loose underfoot and drains well but will not hold a hard surface. Use crushed stone such as 2A modified for a base, and Natural Pea Gravel for walkways, play areas or a decorative bed.

Should I order material by the ton or by the yard?

Both work, and it depends on how you are measuring the job. Bulk aggregate is commonly sold by the ton, while soil, sand and mulch are often ordered by the cubic yard.

Which stone is best for drainage in Westmoreland County?

Clean stone with no fines, because water has to pass through it rather than sit on top. In this county that means 2B stone. It suits French drains, drainage behind retaining walls and shed pads in wet areas. Where you want a slightly smaller clean stone for concrete or tight drainage work, #67 stone is the usual pick.

Gravel, Soil and Stone for Westmoreland County, PA

If you are pricing gravel, stone and aggregate delivery in Westmoreland County, PA, the ground under your job decides most of the answer. Across the plateau hills around Murrysville and Greensburg, clay-rich soils sit on slopes that stay wet, so a base that drains poorly will soften and heave through repeated freeze-thaw. Pennsylvania Rock Supply delivers bulk loads of 2A modified and the other stone, sand and soil local crews ask for, ordered online and dropped at your site.

Delivery across Westmoreland County

You order online, choose a quantity by the ton or by the yard, and size the load with the calculator before you check out. Pick your delivery date at checkout, and a dump truck brings the material to the site.

Bulk delivery covers the whole county, including Murrysville, Greensburg, New Kensington, Jeannette, Latrobe, Monessen, Vandergrift, Scottdale, Mount Pleasant, Irwin, Manor, Loyalhanna, Trafford and Youngwood.

Two things help on delivery day. First, pick a spot a dump truck can reach and turn around in, since a full load is dropped in one pile. Second, order a little over what you think the job needs, because a second run costs you another trip. If you are unsure of the quantity, run the numbers in the calculator first.

Here are the sizes buyers order here, running from the coarsest down to the finest.

2A modified carries the most weight on most jobs here. It is the trade name for a 2A-type base with extra fines added. The fines let it bind and compact, which is what a driveway or a patio base needs on ground that moves. If you are on wet ground, top it with Driveway Gravel after the base is compacted.

For drainage work, clean stone is the right call. #67 Stone handles concrete and drainage where you want a slightly smaller clean stone than #57. Drain Rock suits French drains, downspout runs and drainage behind walls. #89 Crushed Stone is the small washed stone for joints and tight bedding, and River Rock works for decorative beds and dry creek beds. For lawns and beds, Top Soil is screened to take out stones and roots, and Shredded Mulch holds moisture through the summer.

Ground conditions across Westmoreland County

Westmoreland County spans two ground zones, and they behave differently.

Around Murrysville, Greensburg, New Kensington and Jeannette, the plateau hills carry flat-lying shale, siltstone, sandstone, claystone and coal beds weathered into silty, clay-rich soils on hilly ground cut by steep valleys. Many communities sit over old underground coal mines.

Up in the North-central high plateau and Allegheny Mountains, around Ligonier, New Florence, Bolivar and Seward, sandstone, siltstone, shale and conglomerate sit under thin to moderately deep, stony soils on broad uplands and wide ridges, cut by deep, steep-sided valleys. Coal beds and old mine ground occur in parts of the zone.

That drives two practical choices. On the plateau hills, freeze-thaw repeats every winter, and clay-rich soils that stay wet soften and heave, so a thin or poorly drained base breaks up. Frost depth runs about 36 inches there, set by each municipality. Higher up in the mountains, winters are colder and wetter and frost depth commonly runs 36 to 42 inches, also set by each municipality.

Timing matters too. Base, driveway and paver work runs from spring, once the ground has thawed and dried, into late fall, and base stone should not go down on frozen or muddy ground.

Choosing the right material

Somerset County to the south sits in the same North-central high plateau and Allegheny Mountains zone, so the ground is similar to Westmoreland's mountain side. Buyers there work the same thin, stony soils on broad uplands and the same steep-sided valleys, which means the same base and drainage logic holds.

Allegheny County and Washington County both sit in the Western Pennsylvania plateau hills, the same zone as Greensburg and New Kensington. Their silty, clay-rich soils on hilly ground behave like the ground on Westmoreland's western side, so the base and drainage choices carry over almost unchanged.

What shifts is the project, not the material. On gentle upland ground, compacted 2A modified is usually all a drive or pad needs.
