For most Texas Hill Country driveways, crushed limestone is the best gravel choice — it’s locally abundant, compacts tightly under equipment, and holds up to truck and trailer traffic without shifting. But the right answer depends on your property’s slope, how the driveway will be used, and what you’re willing to spend on material versus long-term maintenance.
We’ve matched dozens of Central Texas property owners to the right gravel type, and the decision usually comes down to three things: load bearing needs, drainage characteristics, and what’s cheapest to source near your land. This guide covers every common gravel option for Hill Country driveways, with a straight recommendation for each situation.
Why Gravel Type Matters More Than Most People Think
The number one reason gravel driveways fail before their time isn’t bad weather — it’s using the wrong gravel for the job. Rounded stones like pea gravel look great in a garden but behave like ball bearings under tires. Angular, crushed stone locks together when compacted and stays put. That’s the core distinction that shapes every choice below.
As we cover in our complete gravel driveway guide, a properly built driveway has three layers: a coarse base, a middle drainage layer, and a top surface. The best gravel for each layer is often a different material — and what works well on a flat suburban approach can perform poorly on a steep Hill Country slope.
The Four Gravel Types Used Most in Central Texas
Crushed Limestone
Best for: Base layer and top layer on high-traffic driveways
Crushed limestone is the go-to choice across Hays, Comal, and Blanco counties — and for good reason. It’s quarried close to most Hill Country properties, which keeps delivery costs low. More importantly, it’s angular, meaning the jagged edges of each piece interlock when compacted — and that’s what gives a limestone driveway its load-bearing stability under heavy vehicles.
Limestone works well as both a base layer material and a top layer. If you’re building a full three-layer driveway and want to keep it simple, crushed limestone in different size grades for each layer gets the job done at a lower cost than mixing materials.
Pro Tip: Ask your supplier for #57 crushed limestone for the top layer and crusher run or #411 for the base. The larger stones on top give the driveway a clean, finished look while the finer-grade base locks in tight during compaction.
Drawbacks: Freshly spread limestone is sharp and can be hard on bare feet. It also fades from white-gray to tan over a few seasons — not a problem for function, but worth knowing if appearance near the house matters to you.
Approximate cost: $25–$45 per ton delivered in Central Texas
Caliche
Best for: Budget base layers on flat or gently sloped driveways
Caliche is a naturally occurring mix of calcium carbonate, clay, and soil that’s common just below the surface across the Hill Country. On properties where it’s already present on-site, it can be the most cost-effective base layer available.
When properly graded and compacted, caliche performs well as a foundation material — it gets harder as it dries, which helps it lock in place. The catch is that it can become muddy and soft when saturated, so on low-lying sites or properties with poor drainage, it needs a higher-quality topping to stay passable in heavy rain.
Did You Know? Some Hill Country properties have enough caliche close to the surface that excavation during driveway prep turns up usable base material. That’s a legitimate cost reduction — one we flag for property owners whenever it comes up during a site walk.
Drawbacks: Caliche breaks down faster than crushed limestone under heavy truck traffic and needs replenishment sooner. Not the right choice as a standalone top layer.
Approximate cost: $15–$30 per ton delivered, often less if it’s already on-site
Pea Gravel
Best for: Decorative top layer on low-traffic or pedestrian paths
Pea gravel is small, rounded, and smooth — the kind of stone you see in decorative landscaping. It drains well and looks clean near the house, but shifts constantly under tire pressure. For a parking pad or pedestrian path, it works fine. For a 200-foot rural access road that takes a loaded trailer once a week, it will migrate to the edges within a season and leave bare ruts in the center.
Drawbacks: Disperses under tires, needs frequent raking, and won’t compact into a stable surface.
Approximate cost: $35–$55 per ton delivered
Decomposed Granite
Best for: Decorative driveways and approaches near the home with moderate traffic
Decomposed granite (DG) is a fine-grained, sandy material that packs down smoothly and gives driveways a clean, natural look that fits Hill Country architecture well. It compacts better than pea gravel and drains well, but erodes faster than crushed limestone on steep grades and tracks into the house more than coarser stone. On flat or gently sloped approaches with moderate traffic, it holds up well before needing a fresh top-dressing.
Drawbacks: Erodes faster on sloped sites. Tracks into interiors. Not suitable as a base or middle layer.
Approximate cost: $40–$65 per ton delivered
Which Gravel Should You Choose? A Quick Decision Guide
| Property Situation | Best Choice |
| High-traffic rural driveway or access road | Crushed limestone (all layers) |
| Budget-conscious base layer, flat site | Caliche base + limestone top |
| Decorative approach, light traffic | Decomposed granite |
| Landscaping path or pedestrian walkway | Pea gravel |
| Steep slope or frequent heavy rain | Crushed limestone only — avoid caliche top |
The Layer Strategy Most Property Owners Get Wrong
The most common mistake we see isn’t picking the wrong gravel type — it’s using the same material for all three layers. Each has a different job: the base needs structural strength; the middle layer handles drainage; the top takes daily wear from tires and weather.
A cost-effective Hill Country approach: caliche or crusher run for the base (3 to 4 inches, compacted), #411 crushed limestone for the middle layer (2 inches), and #57 crushed limestone or decomposed granite for the top (1 to 2 inches, depending on traffic). This layered approach costs more upfront than dumping one material throughout, but it lasts far longer and requires less regrading between top-ups.

A Note on Locally Sourced Material
Gravel prices in Central Texas shift based on quarry proximity. Properties closer to quarries near Marble Falls, Georgetown, or Kyle pay less for delivered material; properties farther into the Hill Country pay more per ton. Before ordering, ask whether the supplier is sourcing locally — locally sourced limestone is almost always cheaper on larger jobs and consistently good quality.
Frequently Asked Questions
What is the best gravel for a driveway in Texas? Crushed limestone is the best all-around choice for Texas Hill Country driveways. It’s locally sourced, compacts tightly under equipment, and holds up to heavy vehicle traffic without shifting the way rounded stones do.
Is caliche good for a driveway in Texas? Caliche works well as a base layer on flat sites and is one of the most affordable options in Central Texas. It softens when saturated, so it’s not recommended as a standalone top layer on sites with poor drainage or steep grades.
Can I use pea gravel for a driveway? Pea gravel is not a good choice for a working vehicle driveway. Its rounded shape means it disperses under tire pressure rather than locking in place. It works well for decorative paths, landscaping borders, and light pedestrian walkways.
How often does gravel need to be replenished? Most driveways need a fresh top-up every one to three years, depending on traffic load, gravel type, and how well the driveway was built. Angular materials like crushed limestone last longer between top-ups than rounded stone like pea gravel.
Does gravel type affect how much the driveway costs? Yes, both in upfront material cost and long-term maintenance cost. Premium angular stone costs more per ton but lasts longer between top-ups. Caliche is cheaper but may need replacing sooner on high-traffic driveways. Choosing the right material for each layer usually saves money over time even if it costs more to install.
