Screenings for Patios in Northumberland, PA

Pennsylvania Rock Supply handles gravel and aggregate delivery in Northumberland, PA, and patio work is where the right bedding material matters most. You can order 2A modified, clean stone, sand, topsoil and more online and have it dropped at your site. This is folded bedrock country, so the ground under a patio is rarely flat or forgiving.

If you are building a patio or a set of steps, the material under the pavers decides whether the surface stays flat. Order the wrong bedding and the joints open within a season.

Materials for Northumberland Projects

Bedding is the heart of a patio build. Under pavers you want Screenings, the fine stone dust and chips under a quarter inch that pack firm and hold a screeded bed. It is what you screed to a uniform thickness before the pavers go down.

Below the bedding you need a compacted base that will not pump or shift. 2A Modified is the standard Pennsylvania base stone, crushed stone with the fines left in so it locks up hard when watered and rolled. That is the layer that carries the load.

Drainage under and around flatwork comes next. 2B Stone is washed clean stone with no fines, so water moves through it instead of sitting. Use it behind a retaining wall or in a French drain at the patio edge.

Then the finishes. Washed Sand works for leveling and bedding under pavers and slabs, and Mason Sand is what you want mixed for brick and block mortar or swept into paver joints.

Ground and Conditions in Northumberland

Valleys here are floored by shale or by limestone and dolomite that weather to clay, and the ridges above them shed water fast. A thin patio base laid on that clay shows the failure first: heaving, rutting, and pavers that rock at the corners after a wet winter.

The cause is water. Runoff from steep ridge slopes scours roadside ditches and gravel drives, and the same water finds its way under flatwork. Freeze-thaw cycles heave any base that holds moisture, so the base has to drain as well as compact.

The fix is a compacted 2A modified base with a clean stone drainage layer where water collects. In the limestone and dolomite valleys, concentrated runoff from roofs, gutters and drives can open sinkholes, so keep water moving away from the patio edge.

Timing matters too. Base, driveway and paver work runs from spring, once the ground has thawed and dried, into late fall. Base stone should not go down on frozen, soft or muddy ground.
