Tank Chime Sealing in Saudi | Tank Base Protection System Saudi

Nassguard supplies Tank Chime Sealing in Saudi with the Denso Viscotaq™ Tank Chime Sealing System, a flexible barrier that helps prevent water entering the interface between an aboveground steel tank and its concrete ring wall.

This exposed junction needs protection that follows the tank’s movement during filling and emptying. The Viscotaq tank chime seal combines conformable sealing materials with protective wrapping to maintain coverage around the tank-base perimeter.

Nassguard supplies project and maintenance requirements across Riyadh, Dammam, Jubail, Jeddah and Al Khobar.

What Is the Denso Viscotaq™ Tank Chime Sealing System?

The Denso Viscotaq Tank Chime Sealing System protects the external base area of aboveground steel storage tanks. It seals the junction where the projecting tank-bottom plate meets the supporting foundation.

Its visco-elastic material remains flexible and adhesive, helping the seal accommodate movement without forming a rigid bridge across the interface. The system uses ViscoSealant or a suitable ViscoMastic grade, combined with Viscotaq EZ Wrap and a compatible finish.

The system suits new and existing tanks and can accommodate future inspection and maintenance when the installation preserves the required access.

Key Features of the Tank Chime Sealing System

The system combines water exclusion with flexibility for the tank-to-foundation transition.

• Water-infiltration protection helps protect the concrete ring wall interface.
• Permanent flexibility accommodates movement during filling and emptying.
• Adhesive contact helps maintain a continuous protective barrier.
• Cold application avoids heat-shrinking the sealing layer.
• Conformable materials follow irregular and stepped profiles.
• Weather and salt resistance supports exposed installations.
• Paintable wrapping allows a compatible protective finish.
• Retrofit suitability supports maintenance of existing tank bases.

Applications of Tank Chime Sealing

Tank base corrosion protection should address the full perimeter, including difficult transitions and previous repair areas.

• Aboveground storage tank chimes: Seals the exposed tank-base junction.
• Concrete ring wall interfaces: Limits moisture entry beneath the plate edge.
• New tank installations: Adds external protection following construction and inspection.
• Existing tank maintenance: Renews suitable deteriorated sealing arrangements.
• Stepped foundation details: Profiles irregular transitions before wrapping.
• Inspection-led refurbishment: Incorporates sealing work into a planned tank maintenance programme.

For enquiries from Jeddah, Dammam, Jubail, Riyadh and Al Khobar, include photographs of the chime and foundation. A clear view of gaps, drainage and existing coatings helps define the work accurately.

Tank-Base Preparation and Sealing Installation

A continuous seal needs sound surfaces, complete gap filling and properly finished edges.

• Inspect and photograph defects before covering the area.
• Remove damaged coatings and contamination, then clean and dry the interface.
• Apply adhesion promoter where specified, keeping it within the defined area.
• Pack the selected sealant or mastic into gaps without leaving cavities.
• Create a smooth profile for the wrapping.
• Apply EZ Wrap from the bottom upwards, maintaining overlaps.
• Finish all wrapping and edges with the compatible topcoat.
• Keep required welds visible where the inspection arrangement demands access.

Applicable Standards and Inspection Compatibility

• API 653 — Tank Inspection, Repair, Alteration and Reconstruction: The system accommodates tank inspection programmes through appropriate detailing and preservation of weld access; this is inspection compatibility, not API product certification.
• ISO 8501-1: Provides the steel-surface preparation grades associated with the specified St 2 minimum cleaning.

Inspection and Maintenance

Include the tank chime seal in routine external tank inspections.

• Check upper and lower terminations for lifting or separation.
• Look for punctures, wrinkles and exposed wrapping.
• Inspect the finish after nearby maintenance or accidental impact.
• Investigate ponding water and drainage problems around the foundation.
• Monitor changing gaps that could indicate settlement or movement.
• Preserve inspection access when repairing the seal.
• Record repairs and findings against the tank identification.

A chime seal cannot restore corroded plate thickness, repair structural settlement or replace assessment of a leaking tank.

Frequently Asked Questions

1. What does tank chime sealing protect?
It protects the external tank-base-to-foundation interface against water infiltration.

2. Can Viscotaq accommodate tank movement?
Yes, its visco-elastic materials remain flexible as the tank moves during normal filling and emptying.

3. Can the system cover an existing tank base?
Yes, following inspection, preparation and selection of an appropriate installation arrangement.

4. What are the main system components?
The system combines a suitable sealant or mastic, EZ Wrap and compatible topcoat, with adhesion promoter where specified.

5. Will it interfere with API 653 inspections?
Appropriate detailing preserves required inspection access, including visibility of relevant welds.

6. Does the seal repair tank-bottom corrosion?
No, it provides external protection; existing metal loss requires assessment and any necessary repair.

7. What should I send Nassguard for a quotation?
Provide tank dimensions, gap details, photographs, temperature, quantities and delivery location.

Conclusion

Tank Chime Sealing in Saudi with the Denso Viscotaq system helps protect a vulnerable junction around aboveground storage tanks. Its flexible materials maintain a protective transition between the steel base and concrete ring wall.

Reliable performance depends on preparation, compatible components and continued inspection. Contact Nassguard with your tank-base requirements for supply across Riyadh, Dammam, Jubail, Jeddah and Al Khobar.
