Local fill-dirt in Bexar County is usually native subsoil that contains clay, caliche (limestone fragments), and reddish clay common to the region. Because it is subsoil, it often has low organic matter and can be heavier and stiffer than topsoil.

Yes, expansive clay is common in the San Antonio area and can cause shrink-swell movement if not handled properly. For structural or grade-critical work, use engineered fill or compacted lifts and consider a geotechnical recommendation to reduce future movement.

A tri-axle truck holding roughly 10 to 12 cubic yards equals about 270 to 324 cubic feet. That will cover about 648 square feet at 6 inches depth, 324 square feet at 12 inches, or 1,296 square feet at 3 inches; adjust for your planned depth to estimate coverage.

Generally, untreated fill-dirt is less expensive per cubic yard than crushed gravel because it requires little processing. However, costs depend on local availability, hauling distance, and whether you need compacted or engineered fill versus decorative or base gravel.

The red color comes from iron oxide in the clay minerals common to parts of Texas, including Bexar County. Color does not indicate suitability as fill; test for compaction and drainage instead of judging by color alone.

Bexar County falls mainly in USDA hardiness zones 8b to 9a. For fill-dirt, planting zone matters less than soil composition and organic content; if you plan to landscape, cap the fill-dirt with several inches of topsoil or amended soil suitable for your plants.

For exact soil series and technical maps, consult the NRCS/USDA Web Soil Survey or contact the Bexar County Extension office. Those resources will show local soil series and help you determine if native soils are appropriate as fill or need modification.

Many native subsoils in Bexar County trend neutral to slightly alkaline due to limestone and caliche content. If you plan planting after placing fill-dirt, check pH and add topsoil or amendments as needed for vegetation.

Fill-dirt is intended to raise grade or fill voids and is usually low in organic matter, so it is not ideal for lawns and gardens on its own. For planting, place 4 to 6 inches (or more) of quality topsoil or amended soil over the fill to support plant growth.

Yes, improper use of native fill-dirt over expansive clay or caliche can increase the risk of foundation movement. For building pads, follow a geotechnical report, use engineered fill compacted in lifts, and avoid untested loose fill under foundations.

Fill-dirt density varies, but a practical estimate is about 1 to 1.5 tons per cubic yard depending on moisture and clay content. Because Hello Gravel has a 3-ton minimum, use the cubic-yard-to-ton estimate when calculating how much to order and request a supplier weight estimate if exact tons matter.

Drivers may be able to perform tailgate spreading at their discretion and when safe to do so. Request spreading at checkout, but note Hello Gravel does not guarantee spreading; final decision is up to the driver on site.

For bulk purchases, ordering through Hello Gravel connects you with local suppliers who provide regionally sourced fill-dirt and scheduled dump-truck delivery. For landscape or planting projects, consider buying separate topsoil or compost to cap the fill for plant health.
