Technical guides on liner materials, regulations, and installation practice from the EC Applications field team.
HDPE is the best liner material for most heap leach pads, with LLDPE taking the floors where ore settlement governs and a GCL or compacted clay forming the low-permeability layer underneath. Here is the full ranking, what each material contributes, and how Nevada zero-discharge designs combine them.
Geomembrane selection comes down to five questions: what the liner will contain, what it will be exposed to, what it sits on, how it will be installed, and what standard it must meet. This guide walks through how HDPE, LLDPE, RPP, PVC, and reinforced membranes differ, and how engineers and installers narrow the field to the right material.
A heap leach pad liner is a composite geomembrane system, typically 60 to 100 mil HDPE or LLDPE over a low-permeability soil layer, that contains process solution and routes it to recovery. Here is how the system works, what a typical cross-section includes, and what quality assurance actually prevents.
A methane barrier is a gas-impermeable membrane installed under a building's slab and against below-grade walls to block methane intrusion. Here is what the barrier system consists of, how Los Angeles methane zone requirements work, and what the LADBS approval and inspection process looks like from soil testing to slab pour.
Before lining a produced-water pit, nail down seven things: the permit requirements, the water chemistry, single or double liner, material and thickness, subgrade responsibility, seam testing, and the details at pipes and anchor trenches. Asked up front, these questions set the price, the schedule, and whether the pit passes inspection.
Produced water is the highest-volume waste stream in oil and gas, and a lined pit is often the most economical way to store it. Here is how liner materials, state regulations, QA testing, and installation speed actually work.
If your facility stores more than 1,320 gallons of oil aboveground, the federal SPCC rule requires secondary containment that is sufficiently impervious to hold a spill. Here is how the thresholds, sizing math, liner options, PE certification, and inspection duties actually work.
