Materials for Trafford Projects

Erosion work starts with size. The coarsest stone goes where water hits hardest, and each step down the size range fits a tighter, more finished job.

Riprap and #4 stone armor the places where runoff concentrates. Ballast and 2B stone keep water moving instead of letting it sit against a wall or a pad. Where a base has to lock up hard, 2A modified is the standard Pennsylvania base stone, and screenings finish the surface above it.

For beds, borders and dry creek beds, river rock and large river rock handle decorative and heavier erosion work. On planting areas, topsoil and shredded mulch hold the finish.

Ground and Conditions in Trafford

Trafford sits in the Western Pennsylvania plateau hills. The ground is flat-lying shale, siltstone, sandstone, claystone and coal beds weathered into silty, clay-rich soils, on hilly ground cut by steep valleys.

Heavy rain and snowmelt run down those hillsides, and water soaking into clay layers on slopes is the main landslide trigger. That makes where you send roof and drive runoff a real decision on a hillside lot, not a detail.

Base, driveway and paver work runs from spring, once the ground has thawed and dried, into late fall. Long wet spells and rain on snow are when hillside ground is most likely to move. Repeated freeze-thaw cycles every winter soften clay-rich soils that stay wet, so a thin or poorly drained base breaks up. Frost depth is commonly about 36 inches, set by each municipality.

Questions Trafford Buyers Ask

What stone should I use for drainage in Trafford?

Use clean stone, not a compacting base. 2B stone, also called 3/4 inch clean stone, is the usual pick for French drains and drainage behind retaining walls because water moves through it and it does not pack hard. #57 stone works the same way. For ditch and bank protection, step up to riprap or #4 stone.

What should I have ready when the truck arrives?

A clear path to the dump spot and a firm, level place to set the pile. Know which part of the slope, ditch or drive the material is for, so the driver can drop it close to the work. Keep cars, toys and low wires out of the way before the truck backs in.
