There are many years that adequate secondary containment is a legal requirement in many countries, especially around tanks, storage containers and other plant equipment that contain hazardous liquids. Regulations have been promulgated to establish preventive measures. If you do not comply with these regulations, the companies are subject to costly fines, sometimes subject to criminal proceedings.

Commonly, tile collection tanks, recall blocks and concrete are used as secondary containment systems to protect the environment from spills of corrosive and toxic chemical substances. These materials are economical and offer good structural strength. However, it can easily permeate due to its porosity. They also have some resistance to chemicals, which is susceptible to deterioration by chemical attack. Furthermore, the concrete in particular is very prone to cracking due to the movement of the substrate and the freezing and thawing cycles. If the deterioration is not observed in an early way, the structural integrity of the concrete will suffer and could lead to the contamination of adjacent areas.

But the repair and protection of collecting deposits presents a challenge. Technologies commonly used for the protection of containment areas include tiles, coatings and coatings with fiberglass. The tiles and coatings offer good chemical resistance but have to be quite rigid and susceptible to damage and lamination. The coatings are available in many varieties with different degrees of chemical resistance, flexibility, durability and application complexity, varying in price as well.

Advanced composite and coating systems

Wherever the chemical protection was spoken, the porous substrate does not have the potential to deteriorate quickly. This allows the chemical substance to penetrate through it. Repairs with concrete are very large due to the necessary preparations and the 28-day forging period of cement. In addition, the concrete in the second place on the old concrete, which causes weak areas in secondary containment.

A repair system that facilitates a quick response and offers a long service life is, therefore, a good alternative.

Barrier coatings and polymeric mortars in Belzona were used for the first time to repair collecting deposits in the 1980s. Belzona coating systems and mortars solidify in a few hours and reach all their resistance to chemicals and days.

In addition to repairing the damaged containment areas, Belzona can prevent the problem from simply occurring if protective coverings are used. These coverings also adhere to diverse substrates, among them concrete, metals, tile and existing coverings. Along with its ability to resist a wide range of chemical substances, in all concentrations of caustic substances and up to 98% sulfuric acid, Belzona offers a lasting solution wherever other technologies have been used.

Why choose the coverings and composites of Belzona?

Because the application is simple and fast, with conventional manual tools. The materials are 100% solid, they do not contract after forging. It has an excellent adhesion that prevents delamination and premature death, in addition to its high proven chemical resistance. Drastically reduce the remaining service times and other repair costs.

Where can the polymeric mortars of Belzona be applied?

The materials of Belzona are added to the majority of substrates and are used as a repair and protection system for the following:

  • Chemical Containment Areas
  • Concrete tanks and sinks
  • Supports and vertical structures of concrete
  • Pedestals
  • Alcantarillas and canals
  • Equipment that handle fluids
  • Containers and tubes

In summary, Belzona systems are suitable for use in any place where chemical substances are stored and transported.

What chemical substances can resist the materials of Belzona?

Belzona materials resist a wide range of chemical substances at different temperatures and concentrations. The materials were tested against a wide variety of chemical substances, and their results are registered in the table of chemical resistance available for each product in Belzona suitable for contact with aggressive chemical substances.

Belzona 4311, for example, can be applied for continuous service immersed in 98% sulfuric acid, 30% ammonia, sodium hydroxide, fuel oil and many other aqueous liquids and hydrocarbons.

The range of polymers Belzona Magma, on the other hand, they offer a complete solution for the reconstruction, refurbishment and protection of secondary containment deposits.

Belzona 4111 (Magma-Quartz) Reconstruction of surfaces subject to impact and abrasion
Belzona 4141 (Magma-Build) Lightweight repair material for rebuilding vertical surfaces
Belzona 4181 (AHR MagmaQuartz) For cases where maximum resistance to heat and/or chemical substances is required
Belzona 4131 (MagmaScreed) Kneaded in thin layers for larger areas
