EC Applications installs geomembrane liners across Texas from its Midland office, lining produced water pits, frac water ponds, drilling mud pits, and well-site secondary containment for Permian Basin operators, alongside municipal and industrial lining work statewide.
EC Applications is a geomembrane liner installer serving Texas from an office in Midland, with additional offices in Anaheim, California and Sparks, Nevada. The Midland location puts installation crews and lining material in the middle of the Permian Basin, where most Texas containment work concentrates, while statewide mobilization covers municipal, industrial, and agricultural lining projects from the Panhandle to the Gulf Coast.
The company engineers, fabricates, and installs the full range of containment geosynthetics used in Texas: smooth and textured HDPE and LLDPE, reinforced polypropylene, XR geomembrane, reinforced polyethylene, PVC, geosynthetic clay liner, geotextiles, geonet, and geocomposite. Because panels are fabricated in-house at sizes up to 25,000 square feet, most pit and pond liners arrive as a small number of large prefabricated panels instead of dozens of rolls that have to be seamed together in the field.
Produced water is the hardest fluid most Texas containment systems will ever hold: high total dissolved solids, chlorides well above seawater, and hydrocarbon carryover that attacks the wrong membrane. Pit lining West Texas operators can rely on starts with material selection matched to that chemistry, typically HDPE or a chemically resistant membrane such as XR geomembrane for produced water service, with HDPE, LLDPE, or reinforced polyethylene handling fresh and frac makeup water.
Texas pit construction operates under Railroad Commission of Texas oversight. Statewide Rule 8 has long governed water protection at oil and gas sites, and the RRC's updated waste management rules in 16 TAC Chapter 4 set permitting, liner, and monitoring expectations for produced water recycling pits and other authorized pits. A liner system built to those expectations, with documented material, seaming, and testing, is the difference between a pit that permits cleanly and one that stalls.
Speed matters as much as chemistry in the Permian. Prefabricated panels folded and palletized in the shop mean a frac pond or produced water pit can be deployed and welded out in a fraction of the time field-seamed rolls require, and off-the-shelf inventory for common pit and corral sizes can ship immediately. Fewer field seams also means fewer welds made in West Texas wind and dust, which is where liner defects tend to originate.
Tank batteries, chemical storage, and pump pads in Texas need engineered secondary containment that captures leaks and overfills before they reach soil. Federal SPCC rules under 40 CFR 112 drive containment sizing at facilities storing oil above threshold volumes, and lined earthen berms or prefabricated drop-in liners inside steel containment walls are the standard ways to meet them.
EC Applications installs both permanent field-welded containment systems and prefabricated drop-in liners built to the berm geometry, including boots and seals at pipe penetrations. For standard tank battery layouts, drop-in systems can be fabricated to dimension in the shop and shipped ready to place, which keeps containment work off the critical path when a battery is being set or expanded.
Texas lining work is not limited to the oilfield. EC Applications lines wastewater lagoons, holding ponds, evaporation ponds, and industrial secondary containment for municipal and industrial facilities across the state, where TCEQ permitting typically defines the liner and leak detection requirements. The same materials, fabrication capability, and installation crews that serve Permian operators handle these projects, from a single lagoon reline to multi-cell pond systems.
For any Texas project, the process starts the same way: fluid chemistry, site conditions, and schedule determine the membrane, and prefabrication determines how fast it goes in. Send the dimensions and the application and the team will scope material options and an installation plan.
