Bulk Aggregates for Drainage in North Wales, PA

Pennsylvania Rock Supply handles gravel and aggregate delivery in North Wales, PA. Most jobs here start with 2A modified, the standard base stone, but drainage work needs clean washed stone instead. Mixed Piedmont ground under heavy summer storms sends a lot of water across built-up lots, and that water has to go somewhere.

Materials for North Wales Projects

Drainage is the lead job in this market. Water off roofs, gutters and drives needs clean stone with no fines, because fines pack tight and stop flow. Here are the sizes to know, coarsest to finest, and what each one does.

• #4 Crushed Stone, also called no. 4 stone, is large clean stone used for construction entrances, subgrade stabilization and underdrains.
• 2B Stone, also called 2B clean stone or 3/4 inch clean stone, is washed crushed stone with no fines. It goes in French drains, drainage behind retaining walls and shed pads.
• #57 Stone and #67 Stone are clean drainage stone. Use #57 for retaining wall backfill, and #67 where a slightly smaller clean stone fits the pipe or the wall cavity better.
• Drain Rock covers French drains, downspout runs and drainage behind walls. Pennsylvania yards usually sell clean stone such as 2B for that job.
• Screenings, also called stone dust, are fine crushed chips under a quarter inch that pack firm. Use them for paver bedding, walkway surfacing and pipe bedding.

For a dry well or a footing drain, stay with washed stone all the way. A base material such as 2A Modified or Crusher Run holds the fines, so it compacts and sheds water rather than passing it.

Delivery to North Wales and the Surrounding Area

Order online, choose your quantity by the ton or the yard, size the load with the calculator, then pick a delivery date at checkout. A dump truck brings the material to your site and drops it where you need it.

Delivery covers North Wales and the rest of Montgomery County, including Abington, Cheltenham, Norristown, King of Prussia and Pottstown. Put the drop spot where the truck can reach it and where the pile will not block a drain or a gutter line.

Ground and Conditions in North Wales

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, so timing a delivery matters as much as the material.

Winters here bring repeated freeze-thaw cycles, and frost depth is about 30 to 36 inches as set by each municipality. A thin or poorly drained base can heave and break up even though frost does not reach as deep as it does in most of the state. That is the case for a clean drainage layer under a compacted base.

Storm runoff from paved and built-up ground scours stream banks and washes out ditches, culvert outlets and sloped gravel drives. Loamy upland soils over schist and gneiss drain at one rate, and the heavy clay soils in limestone valleys drain at another. Over limestone, runoff concentrated from roofs, gutters and drives can open sinkholes, so route it away from the foundation.
