Belzona Tank Base Sealing Solutions
Easy, safe and rapid corrosion protection for industrial storage tanks.
Replace failed tank chime seals, stop water penetration and protect tank bottoms against crevice corrosion with Belzona’s tank base sealing solutions.
Above ground industrial storage tanks and their contents are extremely valuable assets that need to be protected. As a result of adverse weather conditions or condensation, moisture can accumulate at the chime angle or track under the base of the tank. This can lead to corrosion problems, leakage or ultimate tank failure.
By installing a Belzona tank base sealing system, you can prolong the tank base service life and reduce the risk of a tank demolition and replacement which often associates with high costs. The system offers an easy, safe and rapid installation. It does not require specialist tools or hot work permits.
How it works
A flexible membrane system in conjunction with a reinforcement sheet encapsulates the circumference of the tank base whilst allowing any residual moisture to permeate through its microporous structure.
- Reduce environmental damage
- Eliminate safety issues
- Increase asset life
Weather- and Waterproof
Prevents ingress of water, resists UV and is tolerant to movement through climatic variations.
Seamless and Microporous
Seals around irregular contours and dissimilar substrates, allows trapped moisture to escape.
High Performance
Offers excellent adhesion, quick back-to-service time and longevity.
Tested and Proven
Belzona membranes have been used by Supermajors in the Oil & Gas, Petrochemical, Power and other industries for many decades.
What causes tank base corrosion?
Tank base corrosion is often caused in the following ways:
- Settlement of storage tank Intermittently immersed in rainwater
- Localised void cavities between tank and base
- Saturated insulation creating localised and severe CUI
- Failure of mastic type sealants
- Cracking and shrinkage of hot bituminous applications
- Fire sprinkler systems creating pooling and ponding around the base
- Tank deluge systems
- Expansion and contraction of tank
Traditional tank base maintenance challenges
Storage tanks can be exposed to extreme weather and operating conditions such as rain, heat and loading. Conventional sealing methods, such as mastic tapes, are subject to shrinkage and UV attack which do not allow moisture to escape.
For a long-term solution it is essential to address the following challenges:
- Allow trapped moisture to permeate out
- Allow flexibility to adapt to thermal expansion loading
- Offer a long-term sealing solution
Belzona Tank Base Sealing Solutions
- Long-term solution: The Belzona solution will not only seal your tank base for 10 years but also allow the tank base to breath and dry out, offering a long-term solution and improvement, making your job easier.
- Cost-Effective: The Belzona approach of sealing prevents the need for a completely new tank base, saving the replacement costs. Offering a long-term protection, it gives you ease of mind for many years.
- Microporosity: The Belzona products permit the substrate to breathe, allowing trapped moisture to evaporate, keeping the tank base dry.
- Durability: Belzona products are resistant to a wide range of chemicals and heat and in addition provide excellent corrosion protection, therefore offering long-term solutions.
