Dirt delivery in Houston
Houston sits on Beaumont Formation clay a few feet above sea level. Nearly every dirt job here comes back to 2 problems: getting water to go somewhere, and getting a slab to sit still. Pool fills run 60 to 100 cubic yards and lot raises are set by a required elevation.
Which material do I need in Houston?
In Houston the clay decides the material. The coastal plain under this city is deep expansive clay that swells when it takes on water and shrinks when it dries. For adding volume, raising a low yard, filling a pool, clay fill dirt is the right and cheapest answer. For anything carrying a slab, a driveway or a footing, you want select fill in 6 to 8 inch compacted lifts, because native Gulf Coast clay moves too much to build on.
What is the ground under Houston made of?
The ground under greater Houston is dominated by the Beaumont Formation: deep, heavy, expansive clay laid down by the rivers that drain to Galveston Bay. It holds water, it stays wet for days after rain, and it changes volume with its moisture content. That mechanism is why this city supports a foundation repair industry the size of the one it has.
The second factor is grade, or the absence of it. The land is close to flat and the water table is close to the surface. Water does not run off a Houston lot so much as sit on it and wait to evaporate. Anything you build has to be higher than the ground around it, which is why so much of the dirt that moves in this market is being used to raise something rather than to level it.
What do people buy dirt for here?
A decommissioned pool is one of the most common reasons a Houston homeowner calls a dirt supplier. The shell gets broken up for drainage and backfilled, almost always with common fill, and it takes far more cubic yards than people expect. A 16 foot by 32 foot pool at an average 5 feet deep is about 95 cubic yards.
Older inner-loop lots settle, and the yard ends up lower than the street and the neighbours. Fill goes in to re-establish fall away from the house. This is the job where getting the material right matters: clay fill for the bulk of the lift, 4 to 6 inches of topsoil on the surface if grass has to grow on it.
New construction on the coastal plain gets built up above the surrounding grade, and floodplain rules in parts of Harris County and the surrounding counties drive how much elevation a given lot needs. Check what your permitting office requires before you work out yardage, because that number is a regulatory input rather than a preference.
Slab-on-grade houses here need the ground beside them to fall away, and 20 or 30 years of settlement undo that. A few cubic yards of clay fill regraded around the perimeter is one of the cheapest things a Houston homeowner can do for a slab, and it is usually a 20 yard order.
What do the local material names mean?
Houston has its own vocabulary for bulk material and the words are not interchangeable. Knowing which one your contractor actually means is the difference between 1 delivery and 2.
The mineral subsoil under the topsoil layer. In this market it runs clay-heavy. Bought for volume: raising ground, filling holes, backfilling pools. The cheapest bulk material sold here and the bulk of what we deliver into Houston.
A separate, spec-driven product blended to compact predictably. It goes under building pads, driveways and flatwork in the Gulf Coast clays. Plans calling for it usually name a plasticity index ceiling and a required compaction percentage against a Proctor test such as ASTM D698.
A sandy fill used where drainage matters more than cohesion, and commonly specified as a levelling or bedding course. It is the Houston homeowner default for filling low lawn areas and it is a different product from select fill with a different gradation and price. Ask us before you order whether we can source it for your address.
Recycled concrete crushed to a gradation and used as a base material for driveways, pads and laydown yards. It is one of the highest demand bulk materials in Houston, running ahead of topsoil on local search volume. It is a base product rather than a fill and it is not interchangeable with select fill. Ask us before you order.
The local name for the heaviest, stickiest of the dark Gulf Coast clays. It describes a soil, not a product you buy. If someone offers to sell you gumbo as fill, understand that you are buying the most difficult material in the region to place, compact and drain.
How do floodplain rules change how much fill I need?
Houston's dirt market is shaped by regulation more than most. Parts of Harris County and the surrounding counties have floodplain development rules that set how high a structure's finished floor has to sit relative to a base flood elevation. Where those rules apply, the volume of fill your lot needs is not a preference you get to optimise. It is an output of a permit condition.
The practical consequence is simple. Get the required elevation from your permitting office or your engineer before you calculate yardage, not after. A lot raise that has to hit a specified elevation is one of the few dirt jobs where ordering short does not just inconvenience you, it fails an inspection. Work out the volume from the required elevation, add 10 to 20 percent for settlement, and order against that number.
The other regulatory input is drainage. Raising your lot moves water somewhere, and in a city this flat, somewhere is usually your neighbour. Detention and drainage requirements exist for that reason. That is a conversation for whoever is designing the grade rather than for a dirt supplier, but it is worth knowing that it is why the yardage on an engineered lot raise is what it is.
How does scheduling and access work here?
Rain is the scheduling variable in this market, not the calendar. Our delivery policy allows for weather days and dry time days because clay that is saturated cannot be placed or compacted, and a loaded truck on a soft lot is a truck that has to be pulled out. After a wet stretch, expect dates to move.
Access is the other one. Inner-loop lots with narrow driveways, low power lines and tight turnarounds may need a smaller dump truck making 4 trips rather than an 18-wheeler making 2. Tell us about the approach when you order, not when the driver is already on the street.
How many yards will my Houston job take?
Houston jobs cluster into 3 sizes. A foundation perimeter regrade is usually 20 to 30 cubic yards, which sits right on our minimum. A back yard raise of 40 feet by 60 feet at 8 inches is about 59 cubic yards loose, so order around 68 with a settlement allowance.
A pool fill is the big one and the one people under-order. Use an average depth across the whole footprint rather than the shallow end. A 16 foot by 32 foot pool at an average 5 feet is about 95 cubic yards. On a tight inner-loop lot that is 8 to 12 tandem loads rather than 4 to 6 on an 18-wheeler, which is why access is worth talking about before you order.
Which cities do we deliver to?
- Houston
- Baytown
- Channelview
We also run north up the I-45 and US-190 corridor, where Madisonville and College Station have their own pages. If your address is outside the list, ask. Coverage is about haul distance from the pit, not about whether a suburb has a page on a website.
Houston dirt delivery questions
How much does it cost to fill a pool with dirt in Houston?
The material quantity is the part we can be precise about: budget 60 to 100 cubic yards for a typical residential pool, using an average depth across the whole footprint rather than the shallow end. The price depends on the material, the delivery address and the truck that can reach your lot, so we quote against the address.
What kind of dirt do I need to raise my yard in Houston?
Clay fill dirt for the lift and 4 to 6 inches of topsoil on top if grass has to grow. Do not use topsoil for the whole lift, because it has organic content, organic content breaks down, and the ground will sink. Do not use clay fill as the surface, because nothing will grow in it.
Do I need a permit to add fill dirt to my Houston property?
It depends on your location, the volume and whether you are in a regulated floodplain. Parts of Harris County and the surrounding counties set finished floor elevations and drainage requirements, and raising a lot changes where water goes. Check with your permitting office before you work out yardage, because the elevation sets the volume.
What is select fill and do I need it in Houston?
Select fill is a graded blend chosen so it compacts predictably, placed in 6 to 8 inch lifts. You need it under anything that carries load: a slab, a driveway, a patio, a footing. On Gulf Coast clay that is standard practice, because the native ground swells and shrinks enough to crack what sits on it.
How soon can you deliver dirt in Houston?
Most orders run 1 to 3 days, because we deliver from material we hold in stock. On very large orders of around 500 loads or more we can source to the cheapest supply instead, which takes longer. Rain is the real variable in this market. Saturated clay cannot be placed or compacted and a loaded truck on a soft lot has to be pulled out.
