Dirt Export and Haul-Off, Explained
Dirt export, or haul-off, is the removal of surplus or unsuitable excavated material from a site. When a job cuts more than it fills, or the native ground cannot stay, the extra dirt has to leave, often by the thousands of cubic yards. This guide explains how export works on commercial sites: why a site generates spoil, why you haul more than you dig, what makes material reusable instead of waste, and how export is priced and moved.
Key takeaways
- Dirt export is the haul-off side of earthwork: moving surplus or unsuitable soil off a site, the mirror image of importing fill.
- Sites generate export from a cut-and-fill imbalance, from basements, ponds, and detention, and from removing soft or expansive clay that cannot support the build.
- Excavated soil swells, so the loose yards you haul are greater than the bank yards you dig. Plan loads on loose volume.
- Clean, inert soil is not solid waste under Texas rules, so it can be hauled to beneficial reuse rather than a landfill, which is usually cheaper and better.
- Trucking distance, volume, and material drive the cost. We size the haul, classify the material, and move it across DFW, Austin, San Antonio, and Houston.
What dirt export actually is
Every site balances two earthwork flows. When a project needs more soil than it has, it imports fill. When it has more soil than it needs, or the soil it has will not perform, it exports the surplus. Export, also called haul-off or dirt removal, is simply the second flow: loading excavated material into trucks and hauling it away so the grade, the foundation, or the structure can be built. It is half of what a soil partner does, and on a cut-heavy site it can be the larger half. We handle export as a commercial service for contractors, site-work crews, and developers, with a 4,000 cubic yard minimum, the same threshold as our import work.
Why a site has dirt to export
Spoil does not appear at random. It comes from a handful of predictable sources, and knowing which one you are dealing with tells you how much will leave and whether it can be reused.
- Cut-and-fill imbalance. When the design cuts more material than it needs for fill, the difference is exported. A balanced site moves dirt around in place; an unbalanced one ships the remainder out.
- Below-grade excavation. Basements, elevator pits, underground parking, detention ponds, and water-quality basins all generate large volumes that have nowhere to go on site.
- Unsuitable or reactive soil. Soft, wet, organic, or high-plasticity expansive clay is often removed and replaced with engineered fill, so the native material becomes export.
- Grade lowering and over-excavation. Dropping a pad or stripping unsuitable subgrade for stabilization produces material that has to be hauled off.
Bank versus loose: why you haul more than you dig
Soil sitting undisturbed in the ground is denser than the same soil after a bucket breaks it up. When you excavate, the material loosens and takes up more space, a behavior called swell or bulking. So the in-place volume you measure, the bank cubic yards, becomes a larger loose volume in the truck, the loose cubic yards. You pay to haul the loose yards, not the bank yards, which is why an export takeoff that ignores swell underestimates the truck count.
Clean fill versus regulated waste
Where the dirt can go depends on what it is. Texas environmental rules draw a clear line between clean, inert material and contaminated waste, and that line decides whether your export is a low-cost reuse or a regulated disposal.
The practical upshot: clean fill is an asset, not just a cost. Surplus soil from one site is exactly the material another site needs to import, and matching the two is cheaper for everyone and keeps usable dirt out of landfills. That matching is the core of soil brokerage, and it is why we run import and export as one network.
What drives the cost of export
Hauling dirt is mostly a trucking problem, so the cost tracks the things that move trucks: how far the material has to travel, how many loose yards there are, and what the destination charges to take it. Clean fill bound for beneficial reuse nearby is the low end; contaminated material bound for a regulated facility far away is the high end. Material type matters too, because heavy, wet soil can hit a legal weight limit before a truck fills, so dense clay can cost more per yard to move than light, dry fill. We quote export by the job, after a takeoff, so the number reflects your actual volume, distance, and material rather than a guess.
How export gets hauled
Once the loose volume is known, the haul is a logistics exercise. Dividing the loose yards by truck capacity sets the load count, which drives site access, staging, and timing. A tandem dump truck carries roughly 10 to 16 cubic yards and larger end-dump and belly-dump trailers carry more, with the exact figure governed by the truck and by DOT axle-weight limits. On a large export we plan the fleet by both volume and weight, sequence loads to keep the excavator working, and confirm the route and destination up front. The cleaner the takeoff, the tighter the schedule.
Setting up export on your job
Have your earthwork quantities or grading plan ready so we can size the haul, and know the material, whether it is clean fill, structural spoil, or reactive clay, so we can route it to reuse or disposal correctly. Scope the volume with our soil calculator, confirm coverage on the service areas page, and send us the details. We will classify the material, price the haul, and schedule the trucks.
