Aggregates & Gravel
Crushed stone, base materials, and gravel sourced directly from our own quarries and pits in the Rio Grande Valley. We own the source — you get the savings.

From our quarries to your job site
Frontera Materials owns and operates quarries and gravel pits across the Rio Grande Valley. That means we control every step — from extraction to crushing to delivery. No middlemen, no markup from third-party suppliers, no supply uncertainty.
Our aggregates are used in road construction, drainage systems, and general site work throughout South Texas. We carry a full range of grades and sizes to meet any project specification.
These same aggregates go directly into our asphalt mixes. Owning the raw material source gives us quality control that most suppliers in the region simply cannot match.

Why Frontera
Why owning the quarry matters
Most aggregate suppliers in South Texas buy from someone else and mark it up. We dig it, crush it, and deliver it. That vertical integration means you pay less and get a more consistent product.
It also means we never run out. When regional shortages hit — and they do — our customers keep their projects moving while others wait. For contractors who need caliche and aggregates on the same job, we handle both from one source.
- Own quarries, caliche pits, and asphalt plants
- Quarry-direct pricing — no middleman
- TxDOT-approved materials
- Same-day delivery available
- Single loads to long-term contracts
- Local team that knows Valley construction
