Screenings for Patios in Lenhartsville, PA

If you need gravel and aggregate delivery in Lenhartsville, PA, you are probably weighing a patio base, a driveway top-up, or drainage behind a wall. Pennsylvania Rock Supply serves both contractors and homeowners here in Berks County, and most patio work starts with 2A modified as the compacted base. Above it, the bedding layer is what keeps pavers flat and true.

The valley ground around Lenhartsville is a mix of shale, limestone and dolomite that weathers to clay, so what you put under a patio matters as much as what you put on top.

Ground and Conditions in Lenhartsville

Folded bedrock gives this part of the state long sandstone ridges and thin, stony soils, with clay-heavy valley floors between them. That clay is the reason a patio base fails early here. A thin lift of stone sitting on wet clay cannot drain, so it holds water, moves under foot traffic, and shows up as sunken pavers and rocking slabs by the next spring.

Cold winters add repeated freeze-thaw cycles that heave and crack a base that stays wet. Municipalities commonly set frost depth at about 36 inches, and that figure belongs to footing design, not to patio stone. Your patio fix is a base that sheds water instead.

Runoff from steep ridge slopes also scours roadside ditches and culvert outlets, and stream banks cut back during heavy rain and snowmelt. In the limestone and dolomite valleys, concentrated roof, gutter and drive runoff can open sinkholes. Plan drainage before you plan the patio.

Materials for Lenhartsville Projects

For a paver patio or flatwork, the bedding layer is the detail that decides how the finished surface looks and how long it stays that way. The materials below cover the bedding, the base under it, and the drainage that keeps both dry.

• Screenings, also called stone dust or #10 screenings, are the standard bedding for pavers and flagstone. They are fine crushed stone under a quarter inch that packs firm, so bedding and pipe work both go quickly.
• 2A Modified, also called modified stone, is the Pennsylvania base stone for driveways, parking pads and shed and patio bases. The fines stay in, so it compacts hard when it is placed and watered in lifts.
• 2B Stone, or 3/4 inch clean stone, has no fines, so water passes through. Use it for French drains, drainage behind retaining walls, and drive bases in wet areas.
• Washed Sand, also called concrete sand, is the leveling and bedding sand for pavers, slabs and concrete work.
• #8 Crushed Stone, known locally as 1B, is the small clean chip for walkways, decorative topping, and asphalt and concrete mixes.

If your patio sits against a slope that stays wet, pair the 2A modified base with 2B stone on the wet side rather than thickening the base alone. Drainage does more for a patio than extra stone.
