Screenings for Patios in Parker, PA

If you need gravel and aggregate delivery in Parker, PA, Pennsylvania Rock Supply supplies bulk material to contractors and homeowners across Armstrong County. Contractors building patios and flatwork order 2A modified and bedding stone, while homeowners order smaller loads for a walkway or a bed. Clay-rich ground on these hillsides sets the rules for what goes under your pavers.

Parker sits on hilly ground cut by steep valleys, so water running off a slope is often the reason a patio fails long before the pavers wear out.

Ground and Conditions in Parker

A patio that fails early usually fails from underneath. The shale, siltstone and clay-rich soils across the Western Pennsylvania plateau hills hold water, and a base that is thin or poorly drained softens and heaves with every winter freeze and thaw.

Repeated freeze-thaw cycles are the reason the base matters more than the surface. When roof and drive runoff is sent toward a patio edge, that water soaks into the clay beneath and keeps it soft through spring.

The fix is a base that drains and a pitch that moves water away from the slab. Clean stone carries water; a material with fines compacts hard but holds moisture, so the two do different jobs and both have a place under flatwork.

Materials for Parker Projects

Under pavers and flagstone, the bedding layer is what makes the surface sit flat. Start with 2A modified, the standard Pennsylvania base stone, crushed stone with the fines left in so it compacts hard and stays put. It carries the load when you build a patio, pad or driveway, and you can see it at 2A Modified.

On top of that compacted base, bedding is where the choice narrows. Screenings, also called stone dust, are fine crushed chips under a quarter inch that pack firm and let you set pavers without them rocking. They bed pavers and flagstone, surface walkways and bed pipe, and you can order them at Screenings.

Where the patio meets a wet slope, drainage has to be handled before the base goes down. 2B stone is clean, washed 3/4 inch crushed stone with no fines, so water moves through it instead of sitting against the wall. It goes in French drains and behind retaining walls; see 2B Stone. For a smaller clean chip on walkways and decorative topping, 1B stone is the half-inch-and-down option at #8 Crushed Stone.

Sand and soil finish the job around the patio. Washed sand is the concrete and leveling sand that beds slabs and pavers, available at Washed Sand, while screened topsoil brings a lawn back after the work is done at Top Soil.

Delivery to Parker and the Surrounding Area

Ordering online lets you pick the material and the quantity together. Bulk stone is sold by the ton or by the cubic yard, and choosing between the two comes down to how you measured your project. The calculator sizes the load from your numbers so the truck arrives with enough material and not much more.

Once the quantity is set, you choose a delivery date at checkout and a dump truck brings the load to your site in Parker. Think about where the truck can back in and where you want the pile dropped, because the material is dumped where it lands.

Delivery covers Parker and the rest of Armstrong County, including Kittanning, Ford City, Leechburg, Freeport and Apollo.

Questions About Gravel and Patio Base in Parker

What gravel is best for a driveway in Parker?

For most driveways here, 2A modified is the base because the fines let it compact hard and hold up through freeze-thaw cycles. Top it with driveway gravel if you want a cleaner surface, or use 2B stone where the drive stays wet and needs water to drain through. On a slope, direct runoff away from the drive so water does not sit in the base.

How much material will my project need?

Use the calculator on the product you are ordering. Enter your measurements and it converts them into tons or cubic yards, so you order a load sized to the job. Measure the area first, including the base layer under a patio as well as the bedding and surface material, and keep the numbers in one place before you order.
