Gravel, Stone and Soil Delivery in Gastonia, NC

Sandy clay loam on a rolling surface

The USDA soil survey maps Madison sandy clay loam, 2 to 8 percent slopes, moderately eroded, at the ZIP's center point. Madison makes up 85 percent of the unit. Moderately eroded means part of the original topsoil has washed off, so the clay-rich layer sits closer to the surface than it once did.^[1]

The survey rates Madison well drained and puts it in hydrologic group B, with moderate infiltration. The top mineral layer is sandy clay loam, and shrink-swell is low, at 1.5 percent. That makes a firm, workable base for a gravel drive. It holds compaction well and does not heave much with moisture.^[1]

Sandy clay loam packs hard when dry and gets slick when wet. Trucks and loaders can rut it after a rain, and a base built on wet ground may settle. Work it when it is damp, not soaked.^[1]

Below the soil, the geologic map shows Foliated to Massive Granitic Rock, made of granite. Weathered granite near the surface can crumble into a gritty sand, while fresh rock deeper down is very hard. The ground at the center point stands at 770 feet above sea level.^[2],[3]

Rain and frost at Gastonia Muni AP

The NOAA normals station at Gastonia Muni AP, NC, about 5 miles away, averages 43.3 inches of precipitation a year. Rain falls in every season. On eroded clay loam, the surface sheds part of a heavy storm as runoff, and that water carries loose gravel and soil downhill.^[4]

The station counts 60 days a year when the low reaches 32 F or colder. Most cold nights are mild, but water held in a soft base can still freeze and loosen stone. The median last spring freeze is March 24, and the median first fall freeze is November 9.^[4]

Building a drive on clay loam

Strip the topsoil, shape the subgrade with a crown, and compact it. Lay woven geotextile fabric. Sandy clay loam is firmer than pure clay, but fabric still keeps fines from mixing into the base on a wet day and adds life to the drive.^[1]

Build Road Base or Crushed Concrete in thin, compacted lifts. Top the drive with 3/4" Crushed Stone or Driveway Gravel. Asphalt Millings pack into a dark, firm surface that sheds water. On the steeper part of a slope up to 8 percent, angular stone holds far better than round Pea Gravel.^[1]

Ditches and swales keep the drive alive. A shallow swale along the uphill side, lined with #57 Crushed Stone, catches runoff before it crosses. A culvert or a stone crossing where the drive meets a low spot keeps storm flow off the surface.^[4]

Stopping erosion on eroded ground

Ground mapped as moderately eroded has already lost soil to runoff, and bare spots will keep losing it. Cover them. Wood Chips and Brown Shredded Mulch protect beds and slopes under trees. River Rock or 1-1/2" Crushed Gravel over fabric covers bare strips along a drive or under a roof edge.^[1]

Where water gathers into a channel, line it with River Rock and set Riprap at the bends and the outlet. A French drain of Drain Rock or #57 Crushed Stone around a perforated pipe pulls water out of a soggy low spot and carries it away.^[1],[4]

Choosing between #57 and #89 Crushed Stone

#57 Crushed Stone is the most common all-round size. Its pieces are big enough to leave open space for water and small enough to walk on. It suits drain trenches, the base under a shed and the strip along a drive.^[1]

#89 Crushed Stone is smaller and packs into a smoother floor. It suits garden paths, the space between pavers and the surface of a patio where bare feet walk. For drainage, choose #57. For comfort and a finer look, choose #89.^[1]

Beds on clay loam

Sandy clay loam holds water and nutrients well but can pack hard. Mix Compost into beds to loosen it. Garden Soil fills raised beds and planting holes. Topsoil rebuilds thin spots where the original surface has eroded.^[1]

Plant tender beds after the March 24 median last spring freeze. Black Shredded Mulch and Red Mulch give color near the house. Pea Gravel, 3/8" Crushed Stone and Walkway Gravel make clean paths. Stone Dust Screenings and Concrete Sand set pavers, and Mason Sand fills the joints.^[4]

Lawns on eroded ground often have thin, patchy spots. Spread a layer of Topsoil over those areas, rake it smooth and seed or sod on top. Fill Dirt suits deeper holes and the backfill around a new wall, where plants will not grow.^[1]

Retaining walls, sheds and side lots

Rolling ground with slopes up to 8 percent invites short retaining walls that turn a sloped yard into flat shelves. Set the first course of block on a compacted pad of Road Base. Backfill behind the wall with #57 Crushed Stone or Drain Rock wrapped in fabric, and run a perforated pipe at the base so water can leave. Native clay loam behind a wall holds water and pushes on the blocks.^[1]

Weathered granite may turn up when a wall footing or a shed pad is dug deep. Gritty, crumbly rock is easy to level and makes a firm floor. Harder rock may call for a change in plan, such as a raised pad built up with compacted Crushed Concrete instead of a deeper cut.^[2]

A shed or a playhouse on clay loam should sit a little above the yard on a pad of compacted stone. Frame it with timber, fill it with Road Base, and top it with #57 Crushed Stone so rain drains out under the floor. Playground Sand or Wood Chips give a soft floor beside a swing set.^[1],[4]

Side lots and the strip behind a garage often collect runoff from the roof and the drive. A shallow swale lined with River Rock moves that water to the street or a lower corner. Fill Sand beds a drain pipe so it sits on an even slope, and Railroad Ballast holds the bank where a swale turns hard.^[1],[4]

Homes in ZIP 28052 and Gastonia

The Census counts 15,288 housing units in ZIP 28052, with a median build year of 1967. Detached single-family houses make up 75 percent of them. Owners live in 55 percent of the occupied homes in the ZIP.^[5]

Gastonia as a whole has 35,337 housing units, and 68 percent are detached houses. The city's median home was built in 1978. The North Carolina Department of Transportation sets Aggregate Base Course, Section 520, Standard Specifications for Roads and Structures (January 2024), as the stone layer under its roads.^[5],[6]
