Gravel, Sand and Mulch Delivery in Birmingham, AL

Plan for heavy rain first

The NOAA normals station at Birmingham AP, AL, about 5 miles away, averages 56.6 inches of precipitation a year. That is a lot of water, and much of it can fall in strong thunderstorms that dump a great deal in a short span. Any gravel surface here needs a place for that water to go, or the fines wash out and the stone starts to scatter.^[1]

Open-graded stone with no fines, such as #57 Crushed Stone or Drain Rock, lets rain drop through instead of running across the top. Use it where water collects: along a wall, under a downspout, or in a trench that carries runoff to the street. Dense Road Base belongs under a drive, where you want the surface to shed water to the edges.^[1]

Snow is light at that station, with 1.4 inches in an average year. The same gauge records 47 days a year when the low drops to 32 F or below. Freeze nights like these can lift poorly drained stone, which gives one more reason to keep water moving out of a base.^[1]

The median last spring freeze at Birmingham AP comes on March 21. The median first fall freeze arrives on November 11. Mulch spread before that first fall freeze helps protect the roots of new shrubs through the colder weeks.^[1]

Built-over ground on old limestone and shale

At the center point of ZIP 35203, the USDA survey maps Urban land, with 95 percent of that map unit paved or built over. Ground like that has been graded, filled and covered many times. When a small patch of it is opened for a planting strip or a parking pad, the first foot can hold brick bits, old base stone, cinders or packed clay.^[2]

Under the fill, the USGS geologic map puts the center point on the Conasauga Formation, a unit of limestone and shale from the Cambrian. Shale weathers into a sticky, fine clay, while limestone breaks into harder blocks. A trench that reaches down that far may turn up either one.^[3]

The ground at the center point stands 600 feet above sea level. On sloped streets, water from uphill lots crosses the lower ones, so look at where runoff enters a site before you set a grade.^[4]

A gravel courtyard or parking strip downtown

Small spaces are the norm in a dense area: a rear courtyard, a strip beside a building, a short alley pad. Begin by digging out the loose top material until you hit something firm, and pull out any large debris. If the subgrade is soft or clayey, lay a woven geotextile fabric so the base stone does not sink into it.^[1],[2]

On top of the fabric, compact a layer of Road Base or Crushed Concrete in thin lifts. Crushed Concrete makes good sense on a site that was once built over, and it packs as tightly as quarried base. Finish with 3/4" Crushed Stone or Driveway Gravel for a clean top surface that drains and gives good footing.^[3]

Slope the finished surface away from any wall, by a small amount over its width. Where the strip meets a building, run a narrow band of Drain Rock or #57 Crushed Stone to take roof water. That keeps water out of the base, which helps it ride out the winter freeze nights without heaving.^[1]

Sheds and small workshops on a tight lot need a level, firm pad. Frame the area, fill it with compacted Crushed Concrete or #4 Crushed Stone, and top it with a thin layer of Stone Dust Screenings that can be screeded flat. A stone pad lets water drain away from the floor and gives the shed a dry footing through wet seasons.^[2]

Raised beds and containers over fill

Planting straight into old urban fill rarely works well, since the native topsoil was stripped or buried long ago. Raised beds solve that. Build a frame, set it on loosened ground, and fill it with Garden Soil or a mix of Topsoil and Compost.^[2],[3]

With this much rain, raised beds also keep roots out of soggy ground. Line the bottom of large planters with a thin layer of #89 Crushed Stone so the soil does not stay waterlogged after a storm. Top each bed with Brown Shredded Mulch or Red Mulch to slow weeds and stop rain from splashing soil onto the pavement.^[1]

Plant cool-season crops early in the spring, and put warm-season plants in after the median last freeze date. River Rock around the base of a bed gives a tidy border that does not wash away.^[1]

Slopes, steps and stone that stays put

Hilly ground and heavy rain together make loose stone travel. A gravel path that runs straight down a slope turns into a gully after a few storms, with the stone piled at the bottom. Run paths across a slope where you can, or break a steep run into short level landings held by timber or stone steps.^[1],[4]

For a path on a grade, angular stone holds much better than rounded stone. Stone Dust Screenings compact into a firm surface that resists washing on a gentle slope, and 3/8" Crushed Stone gives a coarser path that still locks together. Pea Gravel and River Rock roll downhill, so keep them on flat ground or in beds with firm edges.^[2],[3]

At the bottom of a slope, a collection point for runoff saves the rest of the yard. A shallow basin filled with #57 Crushed Stone or Drain Rock lets water sink in or spread out slowly, and a ring of Riprap at the inlet takes the force of the flow. Keep the basin away from the house so the water does not reach a foundation, and clear leaves out of it each fall so it still drains when the freeze nights arrive.^[1]

Before you dig on built-over ground, call the utility locate line and wait for the marks, since old city lots can hide lines, pipes and buried footings in odd places.^[2]

Homes in 35203 and the wider city

The Census counts 2,272 housing units in ZIP 35203. Only 5 percent of those are detached single-family houses, so most homes are apartments, lofts and condos.^[5]

Birmingham as a whole holds 109,349 housing units, and 58 percent of them are detached houses.^[5]

The median build year for homes in ZIP 35203 falls in the 1939 or earlier bucket. The citywide median build year is 1965.^[5]

Owners live in 30 percent of the occupied homes in the ZIP.^[5]

The Alabama Department of Transportation calls the stone layer under its pavements Crushed Aggregate Base, written up in Section 825 of its Standard Specifications for Highway Construction (2026).^[6]
