Screenings for Patios in Bradford Woods, PA

Patio work around Bradford Woods runs from spring, once the ground has thawed and dried, into late fall, and the bedding under your pavers is what decides how that patio looks after a few winters. Pennsylvania Rock Supply sells gravel and aggregate delivery in Bradford Woods, PA, starting with 2A modified, the base stone this market asks for by name.

Under the base sits clay-rich ground on a hillside. Wet clay softens and heaves through freeze-thaw, so a thin base shows its failure fast.

Ground and Conditions in Bradford Woods

The Western Pennsylvania plateau hills leave silty, clay-rich soils over flat-lying shale and sandstone, and water soaking into clay layers on slopes is what gets ground moving. On a patio, that failure mode is a base that stays wet and loses its shape, so pavers rock and joints open.

Send roof and drive runoff away from the patio edge instead of letting it pond against it. A clean stone drainage layer, or a base that drains, keeps the clay under the patio from holding water.

Frost depth here is commonly about 36 inches, set by each municipality. Clay soils that stay wet soften and heave, so a thin or poorly drained base breaks up.

Materials for Bradford Woods Projects

Screenings, also called stone screenings or stone dust, are the fine crushed stone under a quarter inch that packs firm. That is the bedding layer pavers and flagstone sit in, and it is the material most patio jobs here start with. Order Screenings for bedding, walkway surfacing and pipe bedding.

Under the screenings you want 2A modified, crushed stone with the fines left in so it compacts hard. It is the standard Pennsylvania base for driveways, parking pads and patio bases on this ground. Order 2A Modified and compact it in lifts, because one thick loose layer will not tighten up.

Where the patio edge meets a slope or a wet corner, 2B stone gives you a clean, washed crushed stone with no fines. Water moves through it and it does not pack hard, which suits French drains and drainage behind a retaining wall. Order 2B Stone for that work.

For the joints and tight bedding between pavers, #89 crushed stone is a small washed stone that flows into the gaps. Order #89 Crushed Stone for joints and tight bedding.

Finish the planting around the patio with screened topsoil for final grading and bed prep, or shredded mulch for beds and tree rings. Both are the last step after the stone is set.

Questions About Patio Stone in Bradford Woods

What gravel is best for a driveway in Bradford Woods?

Start with 2A modified as the base. It is crushed stone with the fines left in, so it compacts hard and holds up on clay ground. Top it with driveway gravel for the surface. If the drive sits in a wet spot, put clean 2B stone underneath for drainage first. Compacting 2A modified in lifts is what keeps a drive from rutting.

How much material will my project need?

Use the calculator on each product page and enter your measurements. It converts your area and depth into tons or yards, so you can order the right amount the first time. Have your patio or driveway dimensions ready before you start. If you are unsure which unit to order in, order by the yard and let the calculator do the conversion.
