Gravel & Rock ordered online by the ton. A dump truck delivers to your Duncannon address and unloads right where you point.







Contractors tend to buy gravel and rock by the project tonnage, while homeowners often shop by the bag or the truckload. Both need a supplier that delivers without a trip to a yard.
Duncannon gets about 48 inches of precipitation a year, so drainage and washout planning should drive every gravel or rock purchase here.
All products are sold by the ton and delivered in a dump truck. The table below lists the most common sizes and uses.

Perry County, where Duncannon sits, mixes rural lanes and in-town lots. About 82 days a year bring at least a tenth of an inch of rain, so scheduling a delivery onto firm ground matters. The ground around Duncannon is in hydrologic group B, which takes water in at a moderate rate, meaning standard base depth is usually enough.
Duncannon sees about 111 freezing days a year. That freeze-thaw cycle can shift an unsettled base. Winters here are cold enough to move an unsettled base, so compaction is worth the extra pass. Soils mapped in the Duncannon area are commonly well drained, which suggests you might need more or less base stone under the surface layer depending on your specific site.
About 28 inches of snowfall a year means plowing can damage a loose gravel surface. Plan for a top layer that can handle a blade.
