How to Shop Bulk Materials Online at O’Leary Development Group
If you need to buy bulk materials online in San Antonio for a driveway, building pad, landscape project, or site preparation job, we’ve built our online materials store to make the entire process straightforward and fast. At O’Leary Development Group, we know that coordinating material delivery shouldn’t require a dozen phone calls, back-and-forth emails, or driving to a quarry to place an order in person. That’s why we created a simple online catalog where homeowners, landscapers, and contractors across San Antonio, New Braunfels, San Marcos, Bulverde, Seguin, and Boerne can browse our full inventory of aggregates, soils, and base materials, estimate their quantities, and schedule direct dump truck delivery—all from their phone or computer.
In this guide, we’ll walk you through exactly how to shop our online materials store, explain what products we carry, show you how to estimate the right tonnage or cubic yardage for your project, and outline our delivery process across Greater San Antonio and the Hill Country. Whether you’re ordering road base for a private driveway in Bulverde or filling a grading project in New Braunfels, we’re here to help you get the right material delivered efficiently.
Why Local Property Owners Choose to Buy Bulk Materials Online in San Antonio
The San Antonio-New Braunfels MSA has expanded past 2.6 million residents, and that growth drives continuous demand for construction materials, site preparation, and infrastructure development. Texas accounts for nearly 15% of all building permits issued in the United States, and much of that activity runs right through the IH-35 corridor connecting San Antonio, New Braunfels, San Marcos, and Austin. When you’re managing a project—whether it’s a residential driveway, a commercial pad site, or a multi-acre ranch road—coordinating material delivery can become one of the most time-consuming parts of the job.
We built our online materials store to solve that problem. Here’s why local property owners and contractors choose to buy bulk materials online through O’Leary Development Group:
Transparent pricing: You can see exactly what each material costs per ton or cubic yard before you place your order.
Fast scheduling: Select your delivery date and time window directly through our system—no waiting for callbacks.
Full product descriptions: Each material in our catalog includes details about its typical uses, compaction characteristics, and best applications.
Accurate quantity calculators: We provide guidance on estimating tonnage based on your project dimensions.
Local delivery expertise: Our dump trucks serve the entire Greater San Antonio area, and we understand jobsite access across both urban subdivisions and rural Hill Country properties.
💡 Pro Tip: Shopping online doesn’t mean you’re on your own. If you have questions about which material to choose or how much to order, call us before you submit your order. We’re happy to walk through your project and confirm quantities.
New Braunfels and Comal County recorded over 70% population expansion since 2015, with new construction representing approximately 35% of local home sales. That growth creates steady demand for bulk material delivery in San Antonio and surrounding communities, and we see firsthand how challenging it can be to coordinate trucking, confirm availability, and schedule deliveries around tight project timelines. Our online system streamlines that entire process.
Exploring O’Leary Development Group’s Material Catalog: Gravel, Base, and Soils
When you visit our materials catalog, you’ll find a full range of bulk aggregates and soils that we deliver across the San Antonio region. We stock the materials that contractors, landscapers, and homeowners need most for driveways, building pads, drainage projects, and yard improvements. Here’s what you’ll find online:
Crushed Limestone and Gravel
Crushed limestone is one of the most versatile materials we deliver. It works for driveways, pathways, drainage layers, and decorative landscaping. We offer multiple sizes, from fine screenings up to larger decorative rock. If you’re looking to buy gravel online in San Antonio, our catalog breaks down each size and explains where it performs best. For example, 3/4-inch crushed limestone compacts well and creates a stable driveway surface, while larger river rock works better for decorative beds and erosion control.
Road base is a blended aggregate material designed specifically for load-bearing applications. It’s what we recommend for driveway foundations, parking areas, and any surface that will support vehicle traffic. Flex base contains a mix of crushed stone and fines that compact tightly and create a solid, stable layer. When contractors order materials for building pads or heavy equipment access roads, road base is almost always part of the specification.
Fill Dirt and Select Fill
Fill dirt is the workhorse material for grading, leveling, and raising elevations on construction sites. We deliver both standard fill dirt and select fill, which contains fewer organic materials and compacts more predictably. If you’re preparing a building pad, filling low areas, or establishing proper drainage slopes, fill dirt is typically the most cost-effective solution. Our online system lets you order by the load or by estimated yardage, and we’ll coordinate delivery based on your site access and schedule. For a detailed walkthrough, check out our guide on how to order fill dirt delivery in San Antonio.
Bulk Sand
We stock several types of sand, including masonry sand, concrete sand, and fill sand. Sand is essential for mixing concrete, creating bedding layers for pavers and flagstone, improving drainage in heavy clay soils, and filling playground areas. When you buy bulk materials online through our catalog, you’ll see descriptions for each sand type so you can match the product to your specific application.
Topsoil and Compost Blends
For landscaping and yard improvement projects, we deliver screened topsoil and compost-enriched blends that provide a quality growing medium for lawns, gardens, and planting beds. Topsoil delivery is one of our most common residential orders, especially in developments where builders have stripped or compacted the native soil during construction. Ordering topsoil online lets you compare pricing, schedule delivery, and ensure you have enough material to properly establish your landscape.
Mulch and Decorative Rock
We also offer bulk mulch delivery and landscape rock in a variety of colors and sizes. Mulch helps retain soil moisture, suppress weeds, and improve the appearance of planting beds. Decorative rock works well for xeriscaping, drainage features, and low-maintenance landscape design. You can explore different mulch options in our article on bulk mulch types.
How to Estimate Your Tonnage and Buy Bulk Materials Online in San Antonio
One of the most common questions we hear is, “How much material do I actually need?” Estimating quantities correctly saves you money and prevents delays caused by under-ordering or over-ordering. When you buy bulk materials online, understanding the difference between cubic yards and tonnage—and knowing how to calculate both—makes the entire process smoother.

Most bulk materials are sold by the ton, but projects are usually measured in cubic yards. Here’s how the two relate:
Cubic yard: A volume measurement representing a cube that’s 3 feet wide, 3 feet long, and 3 feet tall. This is how you calculate how much space your material needs to fill.
Ton: A weight measurement. Different materials weigh different amounts per cubic yard, so converting between volume and weight depends on the specific product.
For example, crushed limestone typically weighs about 1.3 to 1.5 tons per cubic yard, while sand might weigh closer to 1.2 to 1.4 tons per cubic yard. Fill dirt is often lighter, around 1 to 1.2 tons per cubic yard, depending on moisture content and composition. When you browse our online materials catalog, we provide approximate conversion factors for each product to help you estimate your order.
Basic Calculation Formula
Here’s the formula we use to estimate material quantities:
Measure your area: Calculate the length and width of the space you need to cover (in feet).
Determine your depth: Decide how thick the material layer needs to be (in inches).
Convert to cubic yards: (Length × Width × Depth in feet) ÷ 27 = Cubic Yards
Convert to tons: Cubic Yards × Material Weight per Cubic Yard = Tons Needed
Let’s say you’re building a driveway that’s 50 feet long and 12 feet wide, and you want a 4-inch base layer of road base. First, convert 4 inches to feet (4 ÷ 12 = 0.33 feet). Then calculate: (50 × 12 × 0.33) ÷ 27 = 7.33 cubic yards. If road base weighs approximately 1.4 tons per cubic yard, you’d need about 10.3 tons.
Real-World Estimation Tips
We always recommend ordering slightly more material than your calculations suggest. Material compacts during delivery and installation, and irregular site contours can require more fill than a flat-surface calculation indicates. Adding 5% to 10% to your estimated quantity helps ensure you don’t run short mid-project. If you’re working on a complex grading job or a site with significant elevation changes, reach out to us before you order. We can review your dimensions and provide a more accurate estimate based on our field experience.
💡 Pro Tip: If you’re not confident in your quantity estimate, submit a quote request with your project details. We’ll calculate the tonnage for you and confirm pricing before you commit to the order.

Fast Trucking and Direct-to-Site Delivery Across New Braunfels and the Hill Country
Once you’ve selected your material and estimated your quantity, the next step is scheduling delivery. At O’Leary Development Group, we operate our own fleet of dump trucks, which means we control the entire delivery process from dispatch to placement. That’s a significant advantage compared to suppliers who rely on third-party haulers or require you to coordinate your own trucking.
We deliver across San Antonio, New Braunfels, San Marcos, Bulverde, Seguin, Boerne, and surrounding communities throughout Bexar, Comal, Guadalupe, and Hays counties. Fast-growing Hill Country communities such as Bulverde—where median home values hover around $475,000—feature acreage properties that often require bulk deliveries of road base and crushed stone for private driveways and ranch roads. Our trucks are equipped to handle both tight residential lots and expansive rural properties.
Direct-to-Site Placement
When you order bulk material delivery in San Antonio through our online system, we don’t just drop your material at the curb. We work with you to place it where you need it on your property, whether that’s at the start of a driveway, near a building pad, or staged for a landscaping project. Our drivers are experienced with jobsite navigation, and we’ll coordinate access instructions before delivery day to ensure a smooth drop-off.
Flexible Scheduling
Our online ordering system lets you select your preferred delivery date and time window. We understand that construction schedules shift, and we do our best to accommodate last-minute changes when possible. If you need material delivered early in the morning before a crew arrives, or if you have gate access restrictions during certain hours, let us know in the order notes. We’ll work with your timeline.
Why Delivery Speed Matters
In a region experiencing the kind of growth we’re seeing across the IH-35 corridor, material availability and delivery speed can make or break a project schedule. Texas’s position as a national leader in construction activity means that demand for aggregates, road base, and fill dirt stays consistently high. When you buy bulk materials online and schedule delivery through our system, you’re locking in your material and your delivery slot without the uncertainty of calling around to multiple suppliers or waiting for availability updates.

We’ll also reach out if we need to clarify any site access information or confirm your delivery window. On delivery day, our driver will call when they’re en route so you know when to expect the truck.
💡 Pro Tip: Keep your phone handy on delivery day. Our drivers will call about 15 to 30 minutes before they arrive to confirm you’re ready and verify any last-minute placement instructions.
Preparing Your Site for Dump Truck Material Delivery
Getting the most out of your material delivery means preparing your site properly. When our dump truck arrives, we want to place your material exactly where you need it without delays or complications. Here’s what we recommend:
Clear the Delivery Path
Make sure the route from the street to your material placement area is clear of vehicles, equipment, and obstacles. Our trucks need adequate clearance to maneuver, especially if we’re delivering to a backyard or a location away from the main driveway. If you have low-hanging tree branches, narrow gates, or tight turns, let us know in advance so we can plan accordingly.
Mark Your Placement Area
Use stakes, flags, or spray paint to mark where you want the material placed. This is especially important if you’re ordering multiple loads or if you want material spread across different locations on your property. Clear communication on placement prevents the need for rework and ensures you get your material exactly where you need it.
Check for Underground Utilities
Before any excavation or material placement, call 811 to have underground utilities marked. While we’re not digging, it’s good practice to know where gas lines, water lines, and electrical conduit run across your property. This is particularly important if you’re grading or if our truck will be driving over areas that might have buried infrastructure.
Confirm Access for Heavy Equipment
Loaded dump trucks are heavy. If your driveway or yard has soft soil, recent rain, or poor compaction, there’s a risk of rutting or sinking. If you’re concerned about site conditions, talk to us before delivery. We can recommend lighter load sizes, multiple trips, or alternative placement strategies to avoid damage to your property.
Material delivered by dump truck will come off the truck in a pile. You’ll need equipment or manual labor to spread and grade that material across your project area. If you’re installing a driveway or building pad, plan to compact the material after spreading. Proper compaction is critical for load-bearing applications like road base and flex base. Many homeowners rent a plate compactor or hire a skid steer operator to handle spreading and compaction after delivery.
