South Texas's Local Industrial Mineral Supplier

VP Trading Company is the Rio Grande Valley's locally owned mineral supplier, operating from our Edinburg facility at 19437 FM 493. We supply industrial minerals to construction contractors, civil engineers, soil stabilization subcontractors, and infrastructure project managers throughout Hidalgo, Cameron, Starr, Webb, and all surrounding South Texas counties.

Our proximity is a genuine competitive advantage: while distant suppliers require 3–5 business days for delivery, we typically deliver throughout the Rio Grande Valley within 24–48 hours of order confirmation. When your lime spreader crew is waiting and the grading subcontractor is ready to move, that lead time difference is the difference between a project on schedule and a project day lost.

South Texas Soil — Why Lime Treatment Is Essential Here

South Texas soils present construction challenges that contractors from other regions are often unprepared for. The Rio Grande Valley and surrounding areas are characterized by high-plasticity expansive clays — predominantly smectite (Montmorillonite) group clays with Plasticity Indexes (PI) commonly ranging from 30 to 60. These soils shrink and swell dramatically with moisture changes, causing pavement cracking, foundation movement, and embankment instability when untreated.

Lime treatment is the most effective and economical solution for these South Texas clay conditions. Calcium oxide or hydrated lime reacts with clay minerals in a pozzolanic reaction, permanently reducing plasticity, increasing bearing capacity, and preventing future swell. TxDOT, Hidalgo County, Cameron County, and most South Texas municipalities specify lime treatment for any road or site work on high-PI clay soils.

Construction Minerals We Deliver to South Texas Job Sites

  • Hydrated Lime (Ca(OH)₂) — Standard specification for TxDOT and county road soil stabilization. Pre-slaked, easy to apply with standard agricultural spreader equipment.
  • Quicklime (CaO) — Higher-reactivity option for moisture reduction (drying wet subgrades) and rapid modification. Requires slaking equipment on-site.
  • API Bentonite — For foundation waterproofing applications, slurry wall construction, and directional boring operations.
  • Pond Sealing Bentonite — For agricultural and industrial retention pond liners, reserve pit sealing, and environmental barrier construction.

Serving South Texas Contractors from the Rio Grande Valley

Our delivery network covers all South Texas construction markets: Hidalgo County (McAllen, Edinburg, Mission, Pharr), Cameron County (Brownsville, Harlingen, San Benito), Starr County, Webb County (Laredo), Jim Hogg County, and all surrounding rural areas. We navigate farm-to-market roads, agricultural access roads, and rural construction site conditions that distant suppliers routinely decline.
