Bulk Aggregate Delivery Across Mercer County, PA
If you are building a driveway, setting a patio base or running drainage behind a wall, you need the right stone under it. Pennsylvania Rock Supply handles gravel, stone and aggregate delivery in Mercer County, PA, and 2A modified is the base most local jobs start with. Crushed stone with the fines left in, it compacts hard and holds up under traffic.
Mercer County sits on glaciated ground, so you are working over stony till on the uplands with sand and gravel in many valleys. That shapes what you order and when you can put it down.
Ground Conditions Across Mercer County
The problem a thin base shows here is rutting and pumping in spring. Water perches above the dense till layer from fall into late spring, so low spots, drives and footings stay wet. Snowmelt and heavy rain add to it, and wetlands are common.
The fix is a base that drains and a depth that suits the subgrade. Where the ground stays soft, a clean stone layer lets water move instead of sitting. Long, cold winters bring repeated freeze-thaw cycles, and wet soils above the dense till layer are prone to frost heave under a thin base. Frost depth runs 36 to 42 inches, set by each municipality.
Snow and wet, soft ground can last well into spring. Base work waits until the ground has thawed and drained, then runs into fall. Do not put base stone down on frozen or muddy ground.
Materials Delivered in Mercer County
2A modified is the trade name for a 2A-type base with extra fines added.
2B is #57, and 1B is #8. Order 2A modified for driveways, parking pads, and shed and patio bases.
Clean stone is what handles wet ground. Use drain rock for French drains, downspout runs and drainage behind walls. #89 crushed stone works for joints and tight bedding.
For surfaces, driveway gravel tops a compacted 2A modified base, and walkway gravel gives paths a finer, walkable finish. River rock covers decorative beds and dry creek beds.
Soils round out the order. Topsoil is screened to take out stones and roots for lawns and bed prep. Fill dirt raises grade and backfills before a base or topsoil goes down.

Choosing the Right Material
Ground changes as you cross into neighbouring counties. Butler County and Lawrence County both sit in Southwestern Pennsylvania and span the same glaciated zone plus the Western Pennsylvania plateau hills, so their ground is similar to Mercer County's. Typical projects there follow the same pattern: 2A modified for a base, 2B or #57 for drainage.
Venango County is Northwestern Pennsylvania and spans the North-central high plateau and Allegheny Mountains along with the plateau hills and the glaciated zone. Higher, steeper ground means more attention to slope protection and clean stone on drainage runs.
On your own site, match the material to the job. Wet ground calls for clean stone such as 2B. A drive or pad that needs to pack hard calls for 2A modified. Where the subgrade stays soft, start with fill dirt or a drainage layer before the base goes down.
