Every containment system is designed around the 110% volume requirement in Ontario Regulation 675/98 (Liquid Fuels) and TSSA guidance for above-ground storage tanks, with chemical resistance checked against what you actually store. Containment coatings fail in ways floor coatings never do. A floor coating only has to shed a splash. A containment berm, after a spill, sits full of liquid. Standard epoxy over a slab that emits moisture delaminates under hydrostatic backpressure when the berm fills, letting the spill work under the coating from below. Vinyl ester systems, used for chemical containment under NACE SP0892 and ASTM C722, resist concentrated sulphuric, hydrochloric, and nitric acid, solvents, and petroleum under full immersion where novolac would eventually fail. The Ontario Building Code also requires floors where dangerous goods are stored to be impermeable, and a failed containment surface leaves the owner exposed to soil remediation that routinely costs $50,000-$500,000 per site. Mississauga has a heavy concentration of chemical, fuel, and hazardous material storage, from the Southdown Industrial Area and Clarkson's process plants to fuel storage at logistics hubs around Pearson and generator tanks at hospitals and data centres. Most containment projects run 100-2,000 sq ft and take 1-3 days. Pricing runs $10 to $18 per sq ft installed depending on chemical resistance, system, and documentation. TSSA and CCME compliance documentation is included with every project.

Our systems meet Ontario Regulation 675/98, TSSA technical standards, and the CCME Environmental Code of Practice, with full compliance documentation on every project. ### What Are Secondary Containment Coatings? Secondary containment coatings are immersion-rated epoxy or vinyl ester systems applied to the floors and walls of berms, spill pads, and chemical storage areas to keep fuel or hazardous chemicals out of the concrete and soil during a spill. Unlike floor coatings designed for splashes, they must stay impermeable under static immersion, the full load of a berm after a tank failure. ### What Does a Secondary Containment System Include? - ASTM F2170 moisture verification before application - CSP 3-5 diamond-ground or blast-cleaned surface preparation - Moisture-tolerant primer penetrant coat - Vinyl ester or novolac epoxy base coat (immersion rated) - Oil and chemical separator berm edge detailing - Wall-to-floor junction sealing - TSSA and CCME compliance documentation ### How Much Do Secondary Containment Coatings Cost? Containment coatings in Mississauga run $10-$18 per sq ft installed, depending on chemical resistance, system, and documentation. Most projects are 100-2,000 sq ft. ## Key Benefits of Secondary Containment Epoxy Systems Our containment systems are built for industrial reliability, environmental compliance, and chemical durability, protecting your concrete, your site, and your liability position. ### Environmental and Regulatory Compliance Our coatings are designed to meet provincial and federal requirements, including **Ontario Regulation 675/98**, **TSSA** guidance, and the Ontario Building Code requirement for impermeable floors where dangerous goods are stored. Those rules apply to manufacturing and chemical handling sites across Mississauga, from Southdown to the plants around Dixie Road. Every design includes **110% spill volume verification** and **oil and chemical separator berm detailing**, aligned with the **CCME Environmental Code of Practice**. Following the **NACE SP0892** lining standard keeps surface prep and application at a level that supports audits and environmental reporting. With the Credit River and Lake Ontario shoreline close to many of the city’s older industrial areas, keeping spills out of the soil and groundwater matters. We document substrate moisture, coating thickness, and cure times on every job. That record supports TSSA inspection readiness and ISO 14001 environmental management systems. ### Chemical and Impact Resistance Our industrial containment systems resist the acids, caustics, and hydrocarbons that destroy concrete in a spill. Formulated to **ASTM C722** chemical-resistant mortar performance, they reduce permeability and hold adhesion through thermal cycling and vibration. Where concentrated acids and solvents are handled, **vinyl ester** performs far better than novolac under full immersion. Its dense polymer network resists sulphuric, hydrochloric, and nitric acid and halogenated solvents in tank farms, mixing pits, and transfer areas where a berm fills completely. Impact resistance protects the system long-term. Our commercial-grade materials absorb shock from equipment and drums without cracking, protecting pumps and neutralization basins from damage that would eventually compromise containment. ### Longevity Under Continuous Chemical Exposure Our multi-layer systems combine a primer, immersion-rated mid-coat, and wear-resistant topcoat that handles forklifts and chemical carts. Bond strength between the liner and CSP 3-5 prepared concrete exceeds 300 psi pull-off, maintaining integrity under continuous exposure. A properly installed vinyl ester system lasts **10-20 years** depending on chemical contact, UV, and inspection. We recommend annual inspection of berm edges and junctions. A well-maintained containment coating also protects your position under the Ontario Environmental Protection Act, where soil contamination can mean remediation liability above $500,000 per site. ## Critical Installation Steps and Surface Preparation Containment depends on careful assessment, precise prep, and controlled installation. Hydrostatic backpressure, the coating lifting from below when the berm fills, demands a higher prep standard than any floor. ### Containment Volume Assessment and System Specification Every project starts on site, reviewing the slab, layout, stored substances, and regulations. Moisture readings, chemical compatibility, and volume calculations drive the design, so the system meets **Ontario Reg 675/98** and **TSSA** capacity and documentation requirements. We confirm **110% containment capacity** by calculating wall height, footprint, and internal slope, and specify thickness and primer to **NACE SP0892**. You receive a written scope covering resin selection, base coat thickness, and cure schedule before work begins. ### Concrete Repair and Chemical-Resistant Joint Treatment Sound concrete is the foundation for immersion-rated adhesion. We test strength, remove failed coatings and hollow areas, and fill voids. Structural cracks and cold joints receive flexible sealants or injections rated under **ASTM C722**, the same standard that governs the coating. We add **oil and chemical separator berm details** to manage spills and stop them spreading into neighbouring floor areas. Repairs are finished flush for even coating thickness. Older berms in Mississauga’s established industrial areas usually need this repair phase before recoating. ### Diamond Grinding and Surface Profiling (CSP 3-5) Containment coatings need a CSP 3-5 profile, higher than the CSP 3 used for most floors, because they face backpressure from below that floors never see. A deeper profile means a stronger mechanical bond and better integrity under immersion. Grinding is done with HEPA-filtered, dust-controlled equipment. We then run **ASTM F2170 testing** to confirm vapour emission below 3 lb/1,000 sq ft/24 hr. High vapour emission is the most common cause of containment failure, because the pressure from below lifts the coating when the berm fills. ## Epoxy Flooring Options for Containment Solutions Matching resin chemistry to the stored substance is critical. Putting novolac where vinyl ester is needed produces a system that passes the first inspection and fails in the first real spill. ### Industrial-Grade Novolac and Vinyl Ester Systems Our systems meet **Ontario Regulation 675/98** and **TSSA** guidance, using **ASTM C722** chemical-resistant mortars and dense industrial resins that resist fuels, acids, and alkalis under immersion. **Novolac epoxy** is right for petroleum containment, including fuel berms, transformer dielectric fluid pads, and waste oil sumps. **Vinyl ester** is required when concentrated acids, strong caustics, or aggressive solvents are stored, because its chemistry provides sustained immersion resistance where novolac would soften. Mississauga chemical plants with mixed storage areas often need both within the same containment footprint. | Feature | Specification | | --- | --- | | Chemical Resistance Standard | ASTM C722 Compliant | | Regulatory Compliance | Ontario Reg 675/98, TSSA, CCME | | Spill Capacity | 110% Verified | | Lining Standard | NACE SP0892 | | Liability Coverage | WSIB-Certified, $2M | ### Polyurea Spray Systems for Rapid Return to Service When downtime is the main constraint, polyurea spray systems return to mechanical service in 2-4 hours and full containment service in 24 hours, compared with 5-7 days for epoxy to reach full immersion cure. Polyurea also bridges cracks well. With 300-400% elongation, it accommodates joint movement and substrate cracking that would challenge rigid epoxy, which is valuable on older containment structures where complete crack repair is not always practical. ### Decorative Safety Markings and Zone Demarcation Performance comes first, but clear visual organization helps operations and maintenance. Safety-coded colours mark spill zones, drainage paths, and equipment boundaries. Lines and colour zones are built into the final coating layer without reducing chemical resistance, and colours follow Ontario occupational safety coding for industrial environments. ## Application Areas Across Industrial Sectors Wherever fuel, chemicals, or hazardous materials are stored, containment protects against regulatory and environmental liability. ### Industrial Facilities and Manufacturing Plants Plants handling chemicals, fuels, and wastewater need continuous protection with **110% volume verification** and immersion resistance to acids, caustics, and petroleum. Mississauga’s automotive, aerospace, food processing, pharmaceutical, and electronics plants all have chemical storage and transfer areas that need it. **Oil and chemical separator berm detailing** prevents cross-contamination between zones. Properly lined containment structures typically last 10-15 years longer than bare concrete, which starts absorbing contamination from the first spill. ### Fuel Storage Berms and Transformer Pads TSSA-regulated fuel berms are the most common containment application, from logistics fleets and backup generators near Pearson to industrial yards across the city. Above-ground tank berms must be coated with an impermeable system that meets the 110% requirement under Ontario Reg 675/98. We provide the specification, installation, and documentation package TSSA inspectors expect. Transformer pads need petroleum resistance, UV stability outdoors, and enough flexibility for Ontario freeze-thaw. Novolac with an elastomeric topcoat or a polyurea system is appropriate depending on the thermal profile and return-to-service timeline. ### Commercial and Institutional Environments Hospitals, research centres, universities, data centres, and utilities need containment for chemical storage rooms, generator fuel tanks, and lab chemical stores. These spaces combine regulatory requirements with appearance standards, so our coatings stay cleanable and semi-gloss while resisting chemicals. Each project includes thickness verification, WSIB-certified installation records, and full documentation. For facilities under several regulatory frameworks at once, we structure one documentation package to satisfy all of them. ## Related Questions Facility Managers Ask ### What is the most common failure mode in secondary containment coatings and how is it prevented? Hydrostatic backpressure delamination: the coating lifts from below when the berm fills because moisture pressure in the slab exceeds the coating’s bond. It is the most preventable failure and the most often overlooked. Prevention takes three things: ASTM F2170 testing to confirm vapour emission is within tolerance, a moisture-tolerant primer, and a CSP 3-5 profile for maximum bond. Facilities whose coatings lifted after a spill almost always skipped or shortchanged one of those steps. ### Why does a TSSA inspection sometimes fail a containment system that looks intact? Inspectors look beyond appearance. They check that the chemistry suits the stored substance, the geometry provides 110% volume, wall-to-floor junctions are sealed without voids, and the documentation shows correct installation. A flawless-looking coating of the wrong chemistry, such as standard floor epoxy instead of immersion-rated novolac, will fail because it is not rated for a real spill. ### Can an active industrial facility install containment coatings without shutting down? It depends on size and whether the stored material can be relocated temporarily. Small fuel berms under 500 sq ft can usually be drained, cleaned, and recoated in 48-72 hours. Larger chemical storage floors may need phasing. We build the drying and installation schedule around your operations, provide a written phase plan, and update the documentation to reflect any phased sequence. ### What documentation does a facility need to demonstrate containment compliance? At minimum: the product data sheet confirming immersion rating for the stored substance, installation records showing surface profile, moisture results, thickness per coat, and cure times. For TSSA-regulated fuel storage, add the system specification and the 110% capacity calculation. For sites under Environmental Protection Act oversight, records showing the containment surface is maintained to Ontario Reg 675/98 and CCME requirements. All of it is part of our standard handover package. ### What is the typical remediation cost exposure if a containment coating fails? Soil contamination in Ontario falls under the Environmental Protection Act and Record of Site Condition requirements. Costs depend on extent, substance, and whether an RSC filing is triggered. For petroleum from a failed fuel berm, remediation in the GTA typically runs from $50,000 for a small contained spill to more than $500,000 if contamination reaches groundwater. That is why $10-$18 per sq ft for a properly specified containment coating is risk management, not just maintenance.

They specified vinyl ester instead, calculated the 110% capacity, and documented everything for our environmental file. It has held through two simulated spill tests." Frank D. EHS Manager, Southdown Industrial Area ★★★★★ "TSSA flagged the coating on our fuel berms near the airport. They replaced it with an immersion-rated novolac system, provided the documentation for re-inspection, and finished in two days without interrupting fuelling. The inspector cleared us with no further questions." Lorraine M. Facilities Lead, Airport Corporate Centre ★★★★★ "Transformer pad and oil containment at our Meadowvale campus. They understood the dielectric fluid and maintenance solvent compatibility right away. Fourteen months in, including one small spill the berm held, and no lifting anywhere." Raymond T. Facility Engineer, Meadowvale ## Secondary Containment FAQs ### How much do secondary containment coatings cost in Mississauga? Containment coatings in Mississauga run $10-$18 per sq ft installed, depending on chemistry (novolac or vinyl ester), edge detailing, and documentation. Most projects are 100-2,000 sq ft and take 1-3 days. TSSA and CCME documentation is always included. ### Which coating do we need for our stored chemicals? It depends on the substance. Fuels, petroleum, dielectric fluid, and glycol: immersion-rated novolac epoxy. Concentrated acids, strong caustics, and aggressive solvents: vinyl ester rated under ASTM C722. Many plants in the Southdown and Clarkson areas need both in different zones. We specify from your Safety Data Sheets for the full immersion scenario. ### Can we keep operating while the berm is recoated? Small fuel berms under about 500 sq ft are usually drained, cleaned, and recoated in 48-72 hours while tanks are temporarily emptied. Larger chemical storage rooms are phased section by section. You receive a written phase plan before work starts. ### Why did TSSA fail a coating that looked fine? Inspectors check more than appearance: correct chemistry for the stored substance, 110% volume, sealed wall-to-floor junctions, and installation documentation. Standard floor epoxy in a berm can look perfect and still fail inspection because it is not rated for immersion. ### How do Ontario winters affect outdoor containment berms? Outdoor berms and transformer pads face freeze-thaw, de-icing salt, and big temperature swings. We use flexible epoxy-polyurea hybrids or elastomeric topcoats that bridge micro-cracks and keep chloride out, often building more than 60 mils total on exposed installations.
