Gravel & Aggregate Delivery in Miami-Dade County
The densest construction market in the state, and the place where crushed concrete genuinely competes with virgin rock.
Miami-Dade is our largest market by volume after Broward, and the most competitive by some distance. It is also where the aggregate industry in South Florida physically lives — the pits, the recyclers and the trucking yards are concentrated in and around Medley, which sits at the centre of the county.
Most Miami-Dade deliveries are next-day. Same-day is achievable on staged materials with an early call, but the traffic and the distance make it less reliable than Broward.
Why crushed concrete dominates here
Miami-Dade demolishes and rebuilds more than anywhere else in Florida, and that produces an enormous stream of reclaimed concrete. The processing capacity grew to match it, which means crushed concrete is abundant, consistent and cheap in this county in a way it is not everywhere.
On private work it is the default base on a very large share of jobs. It performs at or near limerock base, it continues gaining strength as residual cement rehydrates, and the price difference is meaningful at any real volume.
The caveat is unchanged: acceptance is job-specific. Some specifications and some inspectors require virgin limerock. Confirm before you build on it — the material is fine, the paperwork is what catches people.
Miami oolite and what it means for you
The limestone under Miami-Dade is Miami oolite, a young, porous formation quite different from the harder Ocala limestone further north. It is quarried extensively in the northwest of the county, and it is the reason base rock is cheap here.
Its porosity also explains the drainage behaviour that catches out contractors from other markets. The rock takes water readily, which is why so much of the county relies on drainage wells and why #57 rock shows up in so many details.
Working in Dade
Two practical realities. First, traffic. A delivery that would take forty minutes at 6 AM takes two hours at 4 PM, and that is a scheduling problem rather than a driving problem. Early deliveries work; late-afternoon deliveries are a gamble.
Second, site density. Much of the county is built out, which means infill sites with no laydown area, deliveries timed against road closures, and general contractors running tight windows. Give us the window and the contact and we will hit it.

Ground conditions in Miami-Dade County
Miami-Dade sits on Miami oolite, and that single geological fact explains a surprising amount about how construction works here.
Miami oolite
Oolite is a young, porous limestone formed from small spherical grains cemented together. It is softer and considerably more permeable than the older Ocala limestone found further north, and it is quarried extensively in the northwest of the county — which is why base rock is cheap in Dade and why the aggregate industry clustered around Medley.
Its permeability is the reason so much of the county drains into wells rather than into surface systems, and the reason #57 rock and other open-graded stone appear so consistently in drainage details.
Thin soil, hard rock
Across much of the county the soil cap is shallow and rock is close beneath it. Excavation frequently means breaking rock rather than digging soil, which changes the economics of any job involving depth — pools, foundations, deep utilities. It also means the subgrade you are building on is often genuinely competent, which is one of the few things that makes construction here easier than elsewhere.
Why recycled material makes sense here
Miami-Dade demolishes and rebuilds at a rate no other Florida county matches, and the processing capacity grew to match the feedstock. The result is that crushed concrete is abundant, consistent and inexpensive here in a way it simply is not in most markets.
On private work it is the default base across a very large share of jobs, and it performs at or near limerock base while continuing to gain strength as residual cement rehydrates. The only real question is acceptance: check your specification before building on it.
Choosing the right material
Most ordering mistakes are not quantity errors — they are the wrong material bought for the job. This is the short version of what goes where.
| If the job is… | Use | Not | Why |
|---|---|---|---|
| Base under pavement, inspected | Limerock base | Shell rock | Spec work needs the certified bearing value. Shell rock will not satisfy LBR 100. |
| Base under pavement, not inspected | Crushed concrete | Virgin limerock | Performs at or near limerock, gains strength over time, costs less. |
| Driveway, pad or ranch road | Shell rock | Spec limerock | Nobody is testing the bearing value. Put the saving into thickness. |
| Driveway wearing surface | Asphalt millings | Loose stone | Binds in the sun into a firm dark surface that does not wash out or dust. |
| French drain or drainfield | #57 rock | Crusher run | Washed and open-graded, so water moves through it. Anything with fines clogs. |
| Under pavers — bedding | Washed concrete sand | Mason sand or stone dust | Only well-graded coarse sand locks under load. One inch, screeded. |
| Permeable paver bedding | #89 rock | Concrete sand | Permeable systems are a different detail — open-graded stone, not sand. |
| Mortar, play areas | Mason sand | Concrete sand | Fine and uniform, so it trowels smoothly and is soft underfoot. |
| Raising grade under a slab | Fill sand | Fill dirt | Drains freely and compacts predictably. Dirt holds moisture and moves. |
| Landscape grade, berms | Fill dirt | Fill sand | Cheaper per ton, and bearing capacity is not the concern. |
| Under new sod | Topsoil | Fill dirt | Fill is deliberately low in organics. Sod on fill declines once it exhausts what it arrived with. |
| Pool deck, path, borders | Pea rock | #57 rock | Rounded and smooth underfoot. Angular stone is uncomfortable and looks harsh. |
| Seawall, shoreline, scour | Rip rap | Anything smaller | Stone has to be heavy enough that design-storm flow cannot move it. |
Not sure? Call and describe the job. We would rather spend two minutes on the phone than deliver the wrong thing.
Timing the work around the weather
South Florida has two seasons that matter to anyone moving material, and planning around them is worth real money.
Wet season, roughly May to October
Afternoon storms are close to daily and they are heavy. Three practical consequences:
- Ground goes soft fast. A site that carried a loaded truck on Monday may not on Wednesday. A tri-axle raising its bed puts enormous load through the rear axles, and we would far rather drop on firm ground near the road than bury a truck on your lot.
- Compaction gets harder. Base and fill compact best at near optimum moisture. Saturated material pumps under a roller instead of densifying, and no amount of extra passes fixes it.
- Uncovered piles absorb water. Topsoil and fine sand are worst affected — a soaked pile is significantly harder to spread. Tarp anything that will sit more than a day or two.
Dry season, roughly November to April
Better ground, easier compaction, and the busiest construction period of the year — which means pits and trucking are in higher demand and lead times stretch. Book earlier than you would in August.
The exception is asphalt millings, which want heat. Millings laid and rolled in June bind within days; the same load in January can take weeks and may need re-rolling.
Hurricane season, June through November
Two effects. Before a storm, demand for rip rap and shoreline protection spikes and everything gets tight. Afterwards, cleanup and repair work absorbs regional trucking capacity for weeks.
If your project involves shoreline protection, do it in the spring. Trying to armour a seawall with a named storm in the forecast is how people end up paying premium rates for whatever stone is left.
How ordering works
There is no account to open and no portal to log into. You tell us the material, the tonnage, the site address and when you need it on the ground, and we come back with a locked, all-in delivered price — usually within the hour during business hours.
That price includes the haul. We quote delivered, not ex-pit, so the number we give you is the number on the invoice. If you are comparing quotes, check whether the other one has trucking in it.
What we need from you
- Material and gradation. If you are working from a plan set, send us the page — it saves a conversation.
- Quantity in tons, or the dimensions. If you have length, width and depth we will work the tonnage out. The tonnage calculator does it too.
- Site address and access notes. Overhead wires, gate widths, soft ground, HOA windows, where exactly the pile goes.
- When you need it. Same-day, a date, or a window against a construction programme.
Payment
First-time customers are COD or prepay for the first few loads. Once there is a clean payment history we move qualified customers onto standard credit terms with a signed credit application. We take ACH, check and major cards, and terms are confirmed at quote rather than negotiated at delivery.
On jobs where we are delivering material to real property we can preserve lien rights under Florida statute by filing a Notice to Owner within 45 days of first delivery. It protects everyone in the payment chain, and it means we get paid, which means you keep getting material on time.
Working out how much you need
Material is sold by the ton. Plans are drawn in cubic yards. That mismatch is where most ordering errors come from, and they are expensive in both directions — running short stops a crew, and over-ordering by a large margin ties up money in a pile.
The arithmetic: multiply length by width by depth in feet, divide by 27 to get cubic yards, then multiply by the material's weight per yard. Most rock runs about 1.35 to 1.4 tons per cubic yard; compacted base is heavier at roughly 1.65; topsoil is lighter at about 1.15.
Then allow for compaction. Base and fill lose roughly 20 to 25 percent of their loose volume once they are properly compacted, so the tonnage you order should be above the theoretical plan volume. Our tonnage calculator builds that allowance in and converts the answer into truckloads.
Order slightly heavy. Two extra tons in a pile costs almost nothing and always gets used. Two tons short on a Friday afternoon costs you a whole extra delivery and a crew standing around.
