Ground and Conditions in Walnut Bottom

A thin base is the failure you notice first here. Cold winters bring repeated freeze-thaw cycles that heave and break up a base that holds water or lacks depth. Frost depth runs about 36 inches, set by each municipality, so pavers laid over a weak layer will not stay flat through spring.

Rain and snowmelt off the steep ridge slopes move fast into the valleys. Where the valley floor is limestone or dolomite, runoff concentrated from roofs, gutters and drives can open sinkholes, so water needs somewhere to go other than under your slab.

That runoff also scours roadside ditches, culvert outlets and gravel drives, and it cuts stream banks during heavy rain and snowmelt. The practical answer is a compacted base that drains, plus clean stone where water collects. 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.

Materials for Walnut Bottom Projects

Patio work starts with what goes under the pavers, and in this market that means 2A modified. It is crushed stone with the fines left in, also called modified stone, and it compacts hard into a firm, unyielding bed. Order it for the base under pavers, patios, shed pads and parking pads. It is the standard Pennsylvania base stone, and it is specified locally by that name. See 2A Modified.

Above the base, bedding is where the finish lives. Screenings, also called stone dust or #10 screenings, are fine crushed stone under a quarter inch that packs firm under pavers and flagstone. They hold a paver bed flat and tight. See Screenings.

Drainage matters as much as bedding. 2B stone, also called 2B clean stone, is washed crushed stone with no fines, so water moves through it instead of packing. Use it in French drains, behind retaining walls and under shed pads in wet areas. See 2B Stone.

For a walkway or decorative topping, 1B stone is the small clean chip, about half an inch and down. Natural Pea Gravel stays loose underfoot on paths and play areas because it is rounded rather than crushed. See #8 Crushed Stone and 3/8" Natural Pea Gravel.

Topsoil and mulch finish the edges of a patio job. Screened topsoil goes down for lawns and final grading, and shredded mulch holds moisture in the beds through summer. See Top Soil and Shredded Mulch.

Questions from Walnut Bottom Buyers

What gravel is best for a driveway in Walnut Bottom?

Start with 2A modified. It is crushed stone with the fines left in, so it compacts hard and carries traffic through freeze-thaw cycles. Top it with driveway gravel if you want a fresh wearing surface. In wet spots, put 2B clean stone underneath for drainage, because it has no fines and water moves through it rather than sitting in the base.

How much material will my project need?

Use the calculator on the product you are ordering. Enter the area and the depth you plan to build, and it returns the quantity in tons or yards. Order the base, bedding and top layers together so the whole job arrives in one delivery. If your numbers land between two figures, size the load with the calculator and round up on the base.
