Rain and snowmelt run fast off the steep valley sides here, so water shows up where you do not want it. Drainage is the first call on most jobs in Orviston.

Materials for Orviston Projects

Most of the work in this valley starts with moving water away from a building, a drive or a ditch. That job takes clean, washed stone with no fines. The fines are what make a base stone pack hard, and packed stone will not pass water. Listed coarsest to finest, here is what to order.

Large and coarse clean stone

Riprap goes on stream banks, ditch bottoms, culvert outlets and slopes that keep washing out. Pennsylvania yards sell it by R-number, with R-4 for ditches and larger R-5 sizes for banks. For underdrains and a construction entrance, #4 Crushed Stone is the big open-graded option.

Drainage stone

2B Stone is the workhorse for French drains, drywells and downspout runs. It is washed 3/4 inch clean stone, so water moves through it instead of sitting on top.

Bedding and fine stone

Screenings, also called stone dust, pack firm for paver and flagstone bedding and pipe bedding. #89 Crushed Stone is the small washed stone for joints and tight bedding. For a walkable surface, #8 Crushed Stone, sold locally as 1B, is the half-inch-and-down clean chip.

Base and soil

When the ground is dry and you need something that locks up, 2A modified is the standard Pennsylvania base stone. It is crushed stone with the fines left in, so it compacts hard under a driveway, parking pad, shed or patio. Set base first, then surface over it with Driveway Gravel.

Delivery to Orviston and the Surrounding Area

You order online, choose your quantity by the ton or the yard, and pick a delivery date at checkout. A dump truck then brings the load to your site. If the drive is tight or the ground is soft, say so and drop the pile where the truck can reach it.

Delivery covers Orviston and the rest of Centre County, including State College, Bellefonte, Boalsburg, Philipsburg and Centre Hall. Bulk stone, sand, soil and mulch all move the same way.

Ground and Conditions in Orviston

This is the north-central high plateau and Allegheny Mountains ground: sandstone, siltstone, shale and conglomerate under stony soils on the ridges, cut by deep, steep-sided valleys. Old mine ground turns up in parts of the zone. Water runs off those valley sides fast and concentrates in the ditches and low drives.

That is why a thin or poorly drained base breaks up here. Cold winters bring repeated freeze-thaw cycles, and frost depth commonly runs 36 to 42 inches, set by each municipality, with the deeper figures in the mountains. A clean drainage layer under a compacted base keeps that water moving.

Timing matters as much as material. Winter snow and frozen ground limit base, driveway and paver work to the thawed, dry months from spring into fall. Base stone should not go down on frozen or muddy ground, so plan the delivery date around the season.
