Screenings for Patios in Allenwood, PA

For gravel and aggregate delivery in Allenwood, PA, timing matters as much as material. Base and paver work runs from spring, once the ground has thawed and dried, into late fall. Pennsylvania Rock Supply stocks the local names you already ask for, starting with 2A modified. Valleys here are floored by shale or by limestone that weathers to clay, so a patio base has to shed water as well as carry weight.

Materials for Allenwood Projects

Under pavers and flatwork, the bedding layer is what holds the surface flat. The right bedding packs firm, drains, and will not shift under a chair leg or a foot. Screenings, also called stone dust, are the fine crushed stone under a quarter inch that does this work. They bed pavers tightly and lock them in place.

Everything under the bedding has to be right first. 2A modified is the standard Pennsylvania base stone, crushed stone with the fines left in, so it compacts hard. It carries the load beneath a patio, a parking pad, or a shed floor. Crusher run does the same job with fines mixed in, though most buyers here ask for 2A modified.

Wet ground changes the plan. 2B stone is clean and washed with no fines, so water moves through it instead of sitting. Use it in a drainage layer under a base in a wet spot.

Sand finishes the job on top. Washed sand, also called concrete sand, levels and beds under pavers and slabs. Mason sand suits brick and block mortar and paver joints. Gravel sand blends coarse sand and fine gravel for leveling.

Ground and Conditions in Allenwood

A base that is too thin or holds water will heave and break up. That is what repeated freeze-thaw cycles do here. Frost depth in this part of Pennsylvania is commonly about 36 inches, set by each municipality, and the ground moves through it all winter.

The local ground makes that worse. Bedrock is folded, with long sandstone ridges and thin, stony soils between them. In limestone and dolomite valleys, runoff concentrated from roofs, gutters and drives can open sinkholes. Runoff off steep ridge slopes scours roadside ditches, culvert outlets and gravel drives.

So the base has to drain as well as compact. Put 2A modified down over a clean stone layer in a wet spot, and never on frozen, soft or muddy ground. Wait for thaw and dry weather.
