POLY·VAS Limited · Initial project enquiries
Protection and rehabilitation of existing concrete structures. POLY·VAS Limited develops technical solutions for existing concrete tanks and containment structures. Based in Nairobi, Kenya, we draw on ideas developed in Germany and practical experience across Europe.
For projects in the Gulf region, we begin with information about the structure, its contents, operating conditions and damage. Local temperatures, exposure and access help determine the materials and installation approach.
What is the problem?
The first step is to identify the cause and extent of the damage.
Existing tanks may show loss of concrete, cracks, leaks or failed protective coatings. The construction, tank contents and operating history help explain the damage and establish which repairs and protection are needed.
What information do we need?
Please send the information already available, including photographs and drawings.
Useful details include the location, tank dimensions, construction type, contents, operating temperatures and observed damage. Previous repairs, access conditions and the proposed shutdown period help us assess how the work could be carried out.
Is a suitable solution possible?
A suitable method must match the concrete, the exposure and the installation conditions.
Mineral systems, resin coatings, reinforced linings and thermoplastic linings have different preparation and application requirements. We compare material resistance, movement and connection details, and identify any further information or inspections needed.
What is TP·VAS?
TP·VAS protects concrete with mechanically fixed PP-H plates and welded flexible FPP cover strips.
The strips close the connections and completely cover the metallic fasteners on the side exposed to the tank contents. Material suitability, anchorage, movement and pipe penetrations are assessed and detailed for each tank.
How can we work together?
Cooperation starts with a technical review and a discussion of the work required.
The next steps cover the proposed scope, material requirements and construction details. Installation arrangements and suitable independent partners are discussed as part of the project planning.
Submit project information
Send a short description of the structure, its contents and the damage, together with available photographs, drawings or inspection reports.
