Gravel, Stone and Soil Delivery in Matthews, NC

Gravelly silt over soft rock

The center point of ZIP 28104 falls in a unit the soil survey calls Tarrus-Urban land complex, 2 to 8 percent slopes. Tarrus soil makes up 60 percent of it. Another 25 percent is urban land, ground that builders have paved, cut or filled, so the soil in one yard can differ from the soil next door.^[1]

Tarrus has a top mineral layer of gravelly silt loam, a fine soil mixed with small rock chips. It is rated well drained and placed in hydrologic group B, where water enters at a moderate rate. Shrink-swell in the top 100 cm is low, at 2 percent, so the ground holds its shape through wet and dry spells.^[1]

Paralithic bedrock begins about 42 inches down. Paralithic means soft, weathered rock that a backhoe can still break, unlike solid bedrock. Most yard jobs stay well above it, but a deep footing, a pond or a long drain line may reach it.^[1]

The geologic map shows Metavolcanic Rock of Neoproterozoic age beneath the point. These old volcanic rocks, changed by heat and pressure, weather into the rocky chips found in the soil above. The ground at the center point stands 730 feet above sea level.^[2],[3]

Rain and frost at the Monroe airport

Monroe AP, NC, about 5 miles from the center point, is the nearest NOAA normals station. It averages 37.9 inches of precipitation a year, and its low falls to 32 F or colder on about 57 days.^[4]

The median last spring freeze at Monroe AP is March 31. The station's median first fall freeze is November 5.^[4]

Mild winters mean frost heave rarely breaks up a sound base here. Summer storms do more damage. A short, heavy rain on a sloped yard can move loose stone and silt in minutes, so every gravel surface should have a planned route for runoff and a firm edge to hold the stone.^[4]

Warm, humid summers also favor weeds in any stone surface that collects soil and leaves. Rake fallen leaves off gravel paths each autumn, and lay fabric under decorative stone so seeds that blow in have less to root into.^[4]

Pine straw and leaves pile up on gravel in the fall in many wooded yards. Blow or rake them off before they rot into the stone, because broken-down leaves fill the gaps and slow drainage.^[4]

Subdivision yards and builder grading

Many houses in the ZIP are recent, and new construction often leaves yards with compacted, stony subsoil and only a thin layer of topsoil on top. Grass struggles on that kind of ground. Spreading Topsoil or Garden Soil over the yard before seeding gives roots a loose layer to grow into.^[1],[5]

Builder grading also shapes where water goes. Watch a rainstorm from a window and note where water collects. Those spots tell you where a French drain or a swale will help most. Fill Dirt can raise a low corner, packed in thin layers and capped with Topsoil.^[1]

Side yards between closely spaced houses often stay shady and bare. A path of 3/8" Crushed Stone or Walkway Gravel over fabric turns that strip into a clean walkway to the back gate, and it drains after every storm.^[5]

Fences, mailboxes and play sets go in often in a newer neighborhood. Set each post in a hole backfilled with 3/4" Crushed Stone, tamped in layers. Stone drains water away from the wood and holds the post as firmly as packed soil, without the rot that comes from a wet hole.^[1]

A driveway extension on gravelly silt loam

Extra parking for a boat, a trailer or a second car is a common project here. Mark out the pad, strip the turf and soft topsoil, and grade the subgrade to fall away from the house. On well-drained gravelly silt loam a fabric layer is optional, though it helps on any patch of soft fill.^[1]

Build the base with Road Base or Crushed Concrete in compacted lifts. Gravelly soil packs well under a plate compactor, and the angular base locks onto it. For the surface, Driveway Gravel matches most existing gravel drives, and #57 Crushed Stone drains faster where the pad catches roof water.^[1]

Where the new pad joins a paved drive, a strip of Asphalt Millings packs into a firm transition that keeps stone off the pavement. Edge the far sides with steel or block so the gravel stays in place.^[1]

Rock chips in gravelly silt loam can dull a tiller and catch on a rake, but they help the subgrade. Leave the small ones in place when you level the pad, and rake out only the pieces large enough to make a lump under the base.^[1]

Beds, mulch and drip lines

Gravelly silt loam drains well but holds few nutrients in its rocky top layer. Work Compost into new beds and plant into a mix of native soil and Garden Soil. After planting, cover the soil with Brown Shredded Mulch, Black Shredded Mulch or Red Mulch to slow drying in summer and keep weeds down.^[1]

Plant tender annuals after the March 31 median last freeze at Monroe AP. Trees and shrubs root best when set out in fall, ahead of the November 5 median first freeze, while the soil stays warm.^[4]

Along the drip line of a roof without gutters, a strip of River Rock or Pea Gravel over fabric stops rain from splashing soil onto siding. The stone strip keeps mulch from washing out of the bed below, too.^[4]

A play area beside the patio needs a soft surface. Wood Chips or Playground Sand, a few inches deep inside a timber or block border, cushion falls and drain quickly on well-drained ground.^[1]

Homes in ZIP 28104 and in Matthews

The Census counts 13,427 housing units in ZIP 28104. Detached single-family houses make up 92 percent of them, the median home was built in 2001, and owners live in 91 percent of the occupied homes.^[5]

The town of Matthews has 12,588 housing units, with 62 percent of them detached. Its median home was built in 1994.^[5]

North Carolina's state reference for a road base is Aggregate Base Course, Section 520, published in the NCDOT Standard Specifications for Roads and Structures (January 2024). A dense, graded base stone of that type suits a home drive just as well.^[6]

With nine in ten homes in the ZIP detached and owner-occupied, most jobs here are classic homeowner projects: fresh mulch every spring, a stone border along the front walk, a gravel pad for the trash cans and a drain for the soggy corner of the yard.^[5]
