Gravel, Crushed Stone and Soil Delivered in Fort Worth, TX

Rock close to the surface

Bedrock sits close to the surface at the center point of ZIP 76102. The USDA survey places hard, lithic bedrock about 17 inches down, which is shallow enough to stop a post-hole auger or a trenching bar on the first afternoon. Anyone planning a fence, a drain line or a footing should expect to break or work around rock rather than dig freely. Breaking rock is slow work, so plan layouts that keep trenches shallow and follow the existing grade wherever possible.^[1]

The rock itself belongs to the Fort Worth Limestone and Duck Creek Formation, undivided, an Early Cretaceous unit made of limestone, marl and clay. Limestone layers are hard, while the marl and clay beds between them soften when they stay wet. A base laid over that mix needs to carry weight across both kinds of material, so compaction and an even subgrade matter more than sheer depth of stone.^[2]

Above the rock sits the Aledo-Bolar-Urban land complex on 3 to 20 percent slopes. Aledo soil makes up 35 percent of the unit and urban land another 40 percent. The top mineral layer is a gravelly clay loam, rated well drained, with a moderate shrink-swell value of 4.5 percent in the top 100 cm.^[1]

Road Base or Crushed Concrete for the drive

Road Base and Crushed Concrete both compact into a hard, interlocking layer, and the choice between them comes down to the job. Road Base is crushed rock with enough fines to bind tight, and it gives the most predictable result under a long driveway or a turnaround that sees trucks. Crushed Concrete does much the same work from recycled material, packs nearly as firmly, and suits a work yard, an equipment pad or a farm lane where looks count for less.^[1]

On a gravelly clay loam with moderate shrink-swell, either one needs a geotextile underneath so the clay cannot pump up into the stone after a soaking rain. Spread the base in thin lifts and pack each one with a plate or roller until a boot heel leaves no mark. With bedrock about 17 inches down, there is little room for deep excavation, so build the drive up slightly rather than cutting it in.^[1]

For the finished surface, Driveway Gravel or 3/4" Crushed Stone spread thin over the packed base gives cars good grip and sheds water toward the edges. Asphalt Millings are another option on a long lane: they bind together as the sun warms them and traffic presses them down, giving a darker, firmer surface over time.^[1]

Storm runoff on group D ground

The NOAA normals station at FT Worth Meacham FLD, about 5 miles away, averages 35.3 inches of precipitation a year. North Texas rain can arrive in short, heavy bursts, and the soil at the center point is in hydrologic group D, the class with very slow infiltration and high runoff. Water that cannot soak in moves sideways, carrying loose stone and mulch with it.^[1],[3]

Plan every surface with that runoff in mind. Crown a gravel drive so water leaves both edges, and line the low side with a shallow swale of River Rock or Riprap that slows the flow without washing out. Around a foundation, a trench of Drain Rock wrapped in fabric, with a pipe to daylight, moves water away from the slab before it can soak the clay under it.^[1]

The Meacham Field station logs 33 days a year with a low of 32 F or colder. Its median last spring freeze is March 11, and its median first fall freeze is November 19. Light freezes like these rarely heave a well-drained base, so the bigger seasonal concern is the swing from soaked clay in spring to cracked, dry clay in late summer.^[3]

Base work goes best once the clay has drained after a rainy stretch. A damp subgrade packs well, while a muddy one squeezes up around the plate and leaves soft spots that turn into ruts later.^[1]

Garden beds over shallow limestone

A bed planted straight into a gravelly clay loam with rock about 17 inches down leaves roots little room. Raised beds filled with Garden Soil, or a thick layer of Topsoil mixed with Compost spread over the native ground, give shrubs and vegetables the depth they need. Marl and limestone below tend to push the native soil toward the alkaline side, so compost-rich fill helps plants that prefer a milder mix.^[1],[2]

Mulch does the most good in a hot summer. A layer of Brown Shredded Mulch or Red Mulch shades the soil, slows moisture loss and keeps clay from crusting. For a low-water bed, Decomposed Granite paths between clumps of native grasses, with River Rock in the drainage low spots, hold up through both storms and dry spells.^[1],[3]

Trees need extra thought where rock sits close to the surface. Dig the planting hole wider rather than deeper, rough up its sides, and backfill with native soil blended with Compost so roots spread outward along the top of the limestone. A ring of Wood Chips out to the drip line keeps that shallow root zone cool and moist through summer heat.^[1],[2]

Patios, paths and play areas

Moderate shrink-swell, at 4.5 percent in the top 100 cm, is enough to tilt a paver patio laid on a thin base. Lay fabric over the clay, pack a solid layer of Road Base, and set the pavers on a screeded bed of Concrete Sand. Firm edging on every side keeps the field tight as the clay below cycles between wet and dry. A flagstone path can rest on Stone Dust Screenings, which pack into a smooth, level bed that is easy to adjust if a stone settles.^[1]

For a play area, Playground Sand or Wood Chips give a soft landing, and either one needs a border to stay in place. Under a swing set on clay, a thin layer of Drain Rock beneath the sand keeps the surface from turning to mud after a storm. Mason Sand works for leveling small spots and for mixing mortar on a low garden wall.^[1],[3]

Housing in ZIP 76102

The Census counts 5,955 housing units in ZIP 76102. Detached single-family houses account for 7 percent of them, and the median home was built in 2006. Fort Worth as a whole holds 373,948 housing units, 65 percent of them detached, with a median build year of 1994.^[4]

Owner-occupied homes make up 21 percent of the occupied stock in the ZIP. Courtyard beds, shared walkways and small commercial lots are common projects in a dense area like this, alongside the yards of detached houses.^[4]

The Texas Department of Transportation sets its own requirements for the stone layer beneath highways as Flexible Base, Item 247, in the Standard Specifications for Construction and Maintenance of Highways, Streets, and Bridges (2024).^[5]
