Tank Base Mastic

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 which can lead to corrosion of the tank base, leakage or ultimately tank failure.

The implications of this however, extend far wider than just the cost of the tank and its contents.

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 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. However, 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

Our Tank Base Mastic & Foundation Solutions

What makes High Performance Tank Base Mastic different?

Long-term solution
•The High Performance Tank Base Mastic solution will not only seal your tank base for 20 years but also allow the tank base to breath and dry out, offering a long-term solution and improvement, making your job easier.

Cost Effectiveness
•The High Performance Tank Base Mastic 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 High Performance Tank Base Mastic product permit the substrate to breathe, allowing trapped moisture to evaporate, keeping the tank base dry.

Durability
•High Performance Tank Base Mastic products are resistant to a wide range of chemicals and heat and in addition provide excellent corrosion protection, therefore offering long-term solutions.

Why does it work?

The supplied Tank Base Mastic system is both flexible and waterproof, and totally protects and encapsulates the circumference of the tank base, whilst allowing any residual moisture under the tank to permeate through the material’s microporous structure.
