Across industrial sites, power plants, and mining operations, protecting soil and groundwater from chemical or fuel leaks is a critical responsibility. A single spill can cause long-term environmental damage, expensive remediation, and regulatory penalties.
That’s why more companies are turning to Secondary containment liners, engineered barriers that prevent leaks from storage tanks, refueling areas, or chemical handling zones from reaching the soil or groundwater beneath.
SAI is a specialist in designing and installing geomembrane containment systems that provide dependable, long-term protection against spills and seepage, helping industries stay compliant, sustainable, and safe.
In simple terms, secondary containment is a protective system designed to capture and control any accidental release from a primary storage unit, such as a fuel tank or chemical vessel.
This “second line of defense” ensures that even if a leak occurs, the material remains fully contained within a lined and sealed area, never reaching the ground or nearby water sources.
For example, a secondary containment system might include:
The core of an effective containment system is the geomembrane liner. These liners, typically made from HDPE (High-Density Polyethylene) or LLDPE (Linear Low-Density Polyethylene), act as a durable, chemical-resistant barrier that prevents hazardous liquids from migrating into the subsurface.
By isolating the stored materials from the surrounding environment, liners:
As a certified contractor, SAI follows strict QA/QC protocols, including seam testing, vacuum inspections, and field verification, to guarantee liner integrity from day one.
Regulatory agencies such as the EPA (under 40 CFR 112 for Spill Prevention, Control, and Countermeasure Plans) and state environmental departments require secondary containment for many storage operations.
Beyond compliance, these systems represent a tangible commitment to environmental stewardship, demonstrating that an organization prioritizes safe, sustainable operations.
By incorporating geomembrane liners into containment systems, companies meet and often exceed these regulatory standards while protecting valuable natural resources.
Secondary containment systems are used wherever chemicals, fuels, or process liquids are stored or transferred. Common applications include:
Groundwater is one of our most valuable and vulnerable natural resources. SAI believes that protecting it isn’t just a regulatory requirement, but a responsibility.
Through careful design, material expertise, and certified installation, we deliver secondary containment systems that stand up to time, stress, and exposure, keeping industries operational and the environment safe.
