Secondary Containment Coating in Greenville, SC
Greenville Supreme Epoxy Flooring has been installing epoxy and concrete flooring systems throughout Greenville, SC and the upstate for over 20 years! Secondary containment coating is a regulatory and safety requirement for any facility that stores, handles, or transfers hazardous fluids — fuels, acids, caustics, solvents, and industrial chemicals that cannot be permitted to reach the ground, drainage systems, or groundwater in the event of a spill or tank failure. The EPA's Spill Prevention, Control, and Countermeasure regulations require secondary containment systems capable of holding 110% of the volume of the largest single container in a storage area. In Greenville and Spartanburg County's manufacturing and industrial corridor along I-85 — home to BMW's Greer plant, Milliken & Company, and a dense network of automotive suppliers, chemical processors, and distribution operations — secondary containment coating isn't an optional upgrade. It's a compliance requirement with inspection and enforcement consequences when it fails or is absent.
The coating system used for secondary containment is not standard epoxy. Containment environments expose flooring and berms to concentrated chemical contact that would degrade a standard epoxy topcoat within months. Greenville Supreme Epoxy Flooring installs chemical-resistant containment coating systems engineered for the specific fluid exposures present at each facility — selected after assessment of what the containment area actually has to hold, not a generic system applied across all applications.

Secondary Containment Coating Services We Provide
Chemical Exposure Assessment & System Specification
No two containment environments have identical chemical exposure profiles. A fuel storage containment area at a distribution facility has different coating requirements than an acid storage area at a metal finishing operation or a caustic chemical containment berm at a food processing plant. Before specifying any system, we assess the chemicals present, their concentrations, contact duration in a spill scenario, and the containment structure's substrate conditions. The coating system is selected based on that assessment — not a catalog default.
Epoxy Containment Liner Installation
High-build, 100% solids epoxy containment liners are the baseline system for most industrial containment applications. Applied at significantly higher film thickness than standard floor coating — typically 30–60 mils versus 10–15 mils for a standard garage floor system — containment liners provide the chemical barrier, crack bridging capacity, and membrane integrity that secondary containment requires. We install containment liners on concrete pads, bermed areas, tank pads, and sumps throughout Greenville and Spartanburg County's industrial corridor.
Novolac Epoxy Systems for Aggressive Chemical Environments
Standard epoxy resin has chemical resistance limits. For containment areas exposed to concentrated acids, aromatic solvents, or oxidizing chemicals, novolac epoxy systems — a modified epoxy formulation with significantly higher chemical resistance than standard bisphenol-A epoxy — are the appropriate specification. Novolac systems are standard in chemical processing, pharmaceutical manufacturing, and metal finishing operations where standard epoxy would degrade under the actual chemical exposure. We specify novolac systems where the chemical assessment indicates standard epoxy resin is insufficient.
Polyurethane & Hybrid Containment Systems
For containment areas that combine chemical resistance requirements with thermal cycling — outdoor fuel storage pads, containment berms subject to seasonal temperature swings, and areas near heat-generating industrial processes — polyurethane and hybrid epoxy-polyurethane systems provide both the chemical resistance and the flexibility that rigid epoxy alone doesn't deliver. Greenville's summer-to-winter temperature range of 95°F+ across a calendar year puts real thermal stress on rigid containment liners. We specify flexible hybrid systems where thermal movement is a factor in the containment design.
Berm, Curb & Transition Coating
Containment systems aren't just floor coatings — they include the berms, curbs, and wall-to-floor transitions that define the containment boundary. A containment liner that terminates at the floor edge without coating up the berm face and sealing the transition is a containment system with a failure point at its boundary. We coat containment areas as complete systems — floor, berm faces, curb tops, and transitions — with cove detailing at all inside corners to eliminate the 90-degree joints where containment liners commonly fail under hydrostatic pressure from pooled fluid.
Containment System Repair & Re-Lining
Existing containment systems with cracked, delaminated, or chemically degraded liners require assessment before re-lining. We evaluate the existing substrate and liner condition, identify failure causes — chemical degradation, thermal stress cracking, or moisture-driven delamination — and specify the appropriate repair and re-lining approach. Re-lining over a degraded liner without addressing the underlying failure cause produces a new containment system with the same failure timeline as the one it replaced.
Types of Facilities We Serve
Manufacturing & Automotive Supply
Greenville and Spartanburg County's manufacturing base — automotive suppliers, metal fabricators, and light industrial operations along the I-85 and I-85 Business corridors — routinely handles hydraulic fluids, cutting oils, coolants, and chemical process solutions that require secondary containment. BMW's Greer facility and its supplier network represent the densest concentration of this demand in the Upstate market. We install containment systems for manufacturing operations throughout the corridor.
Fuel & Chemical Storage Facilities
Above-ground storage tank (AST) pads for fuel, lubricants, and bulk chemical storage are the most common secondary containment application. EPA SPCC regulations require containment capable of holding 110% of the largest tank volume — a specific, auditable standard that containment coating systems must meet and document. We install AST containment systems for fuel storage, fleet maintenance operations, and chemical distribution facilities throughout Greenville County and Spartanburg County.
Food Processing & Industrial Kitchens
Food processing operations handling cleaning chemicals, caustic sanitizers, and acid-based descaling solutions require containment in chemical storage and mixing areas. These environments combine the chemical resistance demands of industrial containment with the sanitation requirements of food-service flooring — a combination that standard containment or standard kitchen flooring alone doesn't address. We specify systems for food processing containment that meet both chemical resistance and sanitation compliance requirements.
Secondary Containment Coating FAQs
What chemical resistance standard should a containment coating meet?
Chemical resistance requirements are specific to the chemicals present — there is no single universal standard. Coating manufacturers publish chemical resistance charts for their products that rate performance against specific chemicals at specific concentrations and contact durations. We cross-reference the chemicals present at your facility against manufacturer resistance data before specifying any system. For regulated facilities, we can provide coating system documentation for compliance records.
How thick does a containment liner need to be?
Minimum film thickness depends on the chemical exposure, substrate condition, and applicable regulations. Most industrial containment liners are specified at 30–60 mils dry film thickness. Containment areas with significant crack potential or substrate irregularity may require thicker systems or membrane reinforcement. We specify thickness based on the actual conditions at each facility.
Can containment coating be applied over existing concrete without full removal?
In most cases yes, provided the existing concrete is structurally sound, the surface is properly prepared, and any existing coating or contamination is fully removed. Oil-contaminated concrete — common in fuel storage and automotive maintenance areas — requires specialized decontamination before any coating will bond. We assess substrate condition during our on-site evaluation and specify the appropriate prep approach.
How long does secondary containment coating installation take?
Installation timeline depends on containment area size, system complexity, cure requirements between coats, and whether substrate repair is needed. Most single-bay industrial containment installations complete in two to four days. Larger or more complex systems take longer. We provide a realistic timeline after the on-site assessment.
Do you provide documentation for regulatory compliance purposes?
Yes. We provide written documentation of the coating system installed — product data sheets, application records, and film thickness documentation — that facilities can maintain for EPA SPCC compliance records and insurance purposes.
