Gravel Delivery in Louisiana

The state geologic map shows loose sediment under our Louisiana cities. At the New Orleans center point it lists silt, clay and sand. Baton Rouge shows the same three. Lafayette adds gravel to the mix, with clay, silt, sand and gravel at its center point. Shreveport is the odd one, with sand, clay, lignite and limestone listed at its center point.^[1]

Rivers laid most of this material down, grain by grain, over a long time. Fine silt and clay settle where water slows and spreads out. That kind of ground is soft and flat, and it holds water close to the surface. For a buyer, this means the native soil in these places will not hold up a driveway on its own, so the strength has to come from stone brought in.^[1]

Hard, angular stone is the piece that the local ground lacks. Crushed rock such as #57 Crushed Stone and 3/4" Crushed Stone is broken from solid bedrock, which gives every piece flat faces and sharp corners that lock when packed. Gravel dug from old river beds tends to be round, which is fine in a garden bed or a drain and weaker under a parked truck. Crushed Concrete is another strong, angular option for a base.^[1]

Lafayette is the one city here where the USDA soil survey names a texture at the center point: silt loam, classed well drained. Silt loam is smooth and easy to dig. It drains at a fair pace when the water table allows, and it softens fast once it is soaked through. Garden plants like it, and stone needs a firm layer under it to stay level there.^[2]

The ground at the New Orleans center point sits at 0 feet, right at sea level. Lafayette reads 40 feet and Baton Rouge 50 feet. Shreveport stands higher, at 180 feet. Treat each figure as one spot on a map. A yard a few blocks away can sit lower or higher, and on flat ground a small dip is enough to hold a puddle for days.^[3]

Louisiana's Department of Transportation and Development writes up the stone course under its pavements as Base Course Aggregates, Stone, Section 302 Class II Base Course, in the Louisiana Standard Specifications for Roads and Bridges (2026). A homeowner does not need to meet a state road book. The lesson carries over well, though: a layer of graded crushed stone, packed tight, spreads a heavy load over soft soil.^[4]

Rain sets the schedule. The weather station used for New Orleans averages 65.9 inches of precipitation a year, and the Lafayette station 62.8 inches. Baton Rouge's station reads 60.5 inches and Shreveport's 48.9 inches. After a big storm on flat clay and silt, standing water can linger in a yard, and a loaded dump truck can sink in where the ground looked firm the day before.^[5]

For that reason, a paved drop spot is the safest choice in all four cities. A concrete driveway, a parking pad or the edge of the street can take the weight of a full truck in any weather. If the stone has to land on grass, wait for a dry run of days and pick the highest, firmest part of the yard. Lay plywood or a tarp under the pile to keep fines out of the turf.^[5]

Cold is rarely in the way. The New Orleans station logs 7 days a year at 32 F or colder, and the Lafayette station 11 days. Baton Rouge's station counts 20 days and Shreveport's 29 days. The New Orleans station averages 0.0 inches of snowfall. Frozen ground almost never holds up a load, and a winter delivery works much like a summer one, as long as the yard is dry.^[5]

Many city lots are tight. Older streets can be narrow, with parked cars on both sides, trees that hang low and wires strung across the drive. A dump truck needs room to back in straight and open air above it to lift its bed. Measure a gate before you count on the truck fitting through it, and tell Gravel Valet about any low branch, soft shoulder or sharp turn when you place the order.^[3]

Think about where water will run once the pile is down. Fines in Road Base and Stone Dust Screenings can wash out of a pile in a downpour and drift onto a sidewalk or into a storm drain. Cover a pile you will not spread right away, or set it where runoff flows toward grass rather than pavement.^[5]

Driveways on soft ground lead the list. On the silt and clay shown at the New Orleans and Baton Rouge center points, dig out the top layer, lay a heavy woven fabric on the subgrade and build up a thick course of Road Base or Crushed Concrete, packed in thin lifts. Top it with Driveway Gravel or #57 Crushed Stone. Raise the finished surface a little above the yard so rain runs off it instead of onto it.^[1]

Drainage comes close behind. With 65.9 inches of yearly precipitation logged at the New Orleans station, low spots and soggy side yards are common complaints. A shallow swale lined with River Rock carries water across a lawn and looks neat doing it. A French drain, filled with Drain Rock around a perforated pipe and wrapped in fabric, moves water under the surface. At a ditch outlet, Riprap keeps fast water from eating the bank.^[5]

Parking pads and shed bases work the same way as a drive, on a smaller scale. A pad for a boat trailer or a camper wants a firm crushed base with the same fabric under it. For a shed, a level frame filled with 3/4" Crushed Stone lets water drain away from the floor and keeps the wood off wet soil.^[1]

Garden beds do well with a lift. Raised beds filled with Garden Soil or Topsoil and mixed with Compost drain better than flat beds on wet silt and clay. The Lafayette center point reads well drained silt loam, which mixes in easily. A cover of Red Mulch, Brown Shredded Mulch or Wood Chips shades the soil in summer and slows weeds.^[2]

Patios, walkways and play areas use the finer products. Pavers sit on compacted Road Base with a bed of Concrete Sand on top. Pea Gravel and Walkway Gravel make a path that drains fast after rain. Playground Sand fills a sandbox, and Fill Sand or Fill Dirt raises a low spot before any of these go in. Our area calculator turns each layer into tons.^[1]
