Screenings for Patios in York, PA

Pennsylvania Rock Supply stocks gravel and aggregate delivery in York, PA, and patio work starts with what goes under the pavers. In this part of South Central Pennsylvania, that base is 2A modified, and the bedding above it is usually screenings.

York County ground runs from loamy uplands to limestone valleys that weather to heavy clay. Each one changes what you order.

Ground and Conditions in York

A patio base that goes down thin or wet shows the same problems here: pavers rock underfoot, joints open, and the surface dips after a wet spring. York County has limestone valleys where soils weather to heavy clay, and that clay holds water instead of draining it.

Once that ground is soft, a compacted base loses its support and the patio moves. The fix is a base built on dry, firm subgrade with the right drainage stone at the edges. Clean stone like 2B lets water pass through instead of sitting in the base.

Heavy summer storms and spring rain run off built-up ground. Roofs, gutters and drives push that water fast, and over limestone ground it can open sinkholes. Direct downspouts and patio runoff away from the base.

Freeze-thaw matters too. Winters here cycle between freezing and thawing, so a thin or poorly drained base can heave and break up. Frost depth runs about 30 to 36 inches and is set by each municipality.

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

Materials for York Projects

Bedding is where patio jobs are won or lost. Screenings, also called stone dust, pack firm under pavers, flagstone and slab edges. The fine crushed chips under a quarter inch lock together and hold a level surface.

Use Screenings for bedding and pipe work. Beneath it, 2A Modified is the standard Pennsylvania base stone, crushed stone with the fines left in, so it compacts hard under a patio, driveway or shed pad.

Where water needs to move, order clean stone instead. 2B Stone is washed 3/4 inch stone with no fines, and it drains behind retaining walls, under shed pads and in French drains.

For sand bedding and mortar, Mason Sand handles brick and block mortar and paver joints. Washed Sand covers concrete and leveling under pavers and slabs.

Around the finished patio, Top Soil handles final grading and bed prep, screened to take out stones and roots.

Questions About Gravel and Patio Base in York

What gravel is best for a driveway in York?

Start with 2A modified. It is the standard Pennsylvania base stone, crushed stone with the fines left in, so it compacts hard and holds up under traffic. Top it with driveway gravel if you want a finished surface. In wet spots, put clean 2B stone underneath for drainage before the base goes down.
