Frequently Asked Questions
Is fill dirt clean?
Our fill dirt is sourced from clean excavation sites and is free of organics, trash, and large debris. It's appropriate for grading and compaction.
Can fill dirt be used for a garden or lawn?
Fill dirt lacks the organic content for healthy plants — it's best used below grade as a base, topped with screened topsoil for growing applications.
What's the difference between fill dirt and topsoil?
Fill dirt is subsoil used for grading and structural fill. Topsoil is nutrient-rich surface soil for growing. Both are available — call to discuss your project.
How deep should fill dirt be for a building pad?
Depth depends on the existing grade and how much lift is needed. Most building pads use 2-4 feet of compacted fill. We can help estimate your site.
Can fill dirt be compacted?
Yes — our fill dirt is compaction-grade. It should be compacted in 6-8 inch lifts for structural applications like building pads and foundation support.

Fill Dirt Delivery in San Marcos, TX — What You Need to Know Before Your Project Starts
San Marcos sits in Hays County, where the native soil is often Houston Black clay — a high-shrink, high-swell material that becomes very plastic when wet and extremely firm when dry. If you are building a pad, leveling a yard, or grading a lot, understanding what is already in the ground matters before you bring in fill. Importing clean fill dirt gives you a more stable, workable base that behaves predictably under load and weather.
Construction projects in San Marcos that involve significant land disturbance or the placement of fill material typically require a Site Development Permit from the City. This applies to grading, filling, and related earthwork across much of the city's jurisdiction. Getting that permit sorted before delivery day keeps your project on schedule and avoids stop-work orders.
San Marcos also falls within the Edwards Aquifer recharge and contributing zones. The Texas Commission on Environmental Quality regulates construction activities in these areas, including clearing, grading, and the placement of fill. If your site is near a recharge zone, you may need to take extra steps to document the material you are bringing in and how it is managed on site.
The City requires erosion and sediment controls on construction sites — things like silt fences — to prevent fill material and runoff from reaching local waterways. We work with contractors and homeowners who are already thinking about this, and we can time deliveries to fit your site prep and stormwater control schedule.
If your project is in or near a 100-year floodplain, placement of fill is subject to additional permitting to make sure it does not raise flood levels on neighboring properties. Know your site's floodplain status before your first load arrives. We can work around these requirements — we just need to know upfront so we can plan accordingly.
Why San Marcos Contractors and Homeowners Work With O'Leary Development Group
We are a local hauling and material delivery operation based in South Texas. We do not manage projects from a call center — we work in the field, and we understand what it takes to get material to a job site on time without creating problems for your crew or your schedule.
San Marcos has real regulatory layers — site development permits, Edwards Aquifer rules, stormwater requirements, and floodplain restrictions. We are familiar with how these affect delivery timing and site logistics. When you tell us what your project involves, we can help you think through the delivery sequence so it fits what is happening on the ground.
Houston Black clay in Hays County means a lot of sites need imported fill to get a workable base. We deliver clean fill dirt that is appropriate for building pads, yard leveling, and site grading — material that performs the way you need it to, not whatever happened to be available that day.
We serve San Marcos along with Kyle, Buda, New Braunfels, Wimberley, and Seguin. If your project spans multiple sites or phases, we can coordinate deliveries across locations. Our goal is to be the material and logistics partner you call once and rely on throughout the job.
