Start with the calculator, then pick your stone. Pennsylvania Rock Supply handles gravel and aggregate delivery in Downingtown, PA, and everything we carry starts with 2A modified when a project needs a base. Downingtown sits on mixed Piedmont ground, so a bed or a dry creek bed here often needs clean stone and a little more depth than the uplands suggest.

You order online, choose your quantity by the ton or yard, and a dump truck drops it at the job site.

Delivery to Downingtown and the Surrounding Area

Ordering online keeps it simple. Enter your address, size the load with the calculator, and pick a delivery date at checkout. If you are not sure whether you need a ton or several yards, the calculator does the figuring for you.

Bulk delivery comes by dump truck and drops where you point it, so have the spot cleared before the truck arrives. We deliver across Downingtown and Chester County, including West Chester, Phoenixville, Coatesville, Exton, and Paoli.

For a landscape job, that usually means setting the pile close to the bed or the drainage run so you are not moving stone twice. A decorative order and a base order can both land the same day if you schedule them that way.

Materials for Downingtown Projects

Most landscape work in Downingtown comes down to decorative stone, bed material, and clean stone for water. Here is what to order for each job.

Decorative beds and dry creek beds

For beds, borders, and dry creek beds, River Rock and Large River Rock are the ones to order. Large River Rock carries the heavier erosion work in a dry creek bed, while the smaller river rock finishes borders and open beds. For a softer ground cover under plantings, 3/8" Natural Pea Gravel stays loose underfoot and drains well.

Driveways and bases

A driveway starts with 2A modified, the standard Pennsylvania base stone. The fines stay in it, so it compacts hard and locks up under traffic. Top it with Driveway Gravel for a clean running surface.

Drains and wet spots

Where water needs to move, use clean stone. 2B Stone goes in French drains, behind retaining walls, and under shed pads in wet areas. It has no fines, so water passes through instead of packing hard.

Walkways and bedding

Walkway Gravel gives paths a finer, walkable surface. Under pavers and flagstone, Screenings pack firm and hold a level bed.

Ground and Conditions in Downingtown

Downingtown sits on mixed Piedmont ground. Uplands are loamy soils weathered from schist and gneiss, the lowlands run to red shale and sandstone, and the limestone valleys weather to heavy clay. Each one behaves differently under a base.

That clay is the one that catches people out. It holds water, so a thin base over it stays soft and moves. Clean stone helps here, because it lets water drain instead of sitting in the subgrade.

Over limestone, watch how runoff concentrates. Water off roofs, gutters, and drives can open sinkholes where it collects, so send downspouts and driveway drainage somewhere safe.

Summer storms and spring rain push runoff off built-up ground, and that water scours stream banks and washes out ditches, culvert outlets, and sloped gravel drives. Riprap and clean stone armor those spots.

Winters bring repeated freeze-thaw cycles, and frost depth in this part of the state runs about 30 to 36 inches, set by each municipality. A thin or poorly drained base can heave and break up even though frost does not reach as deep here as in most of the state.

Base, driveway, and paver work runs from spring, once the ground has thawed and dried, into late fall. Do not put base stone down on frozen, soft, or muddy ground.
