POLY·VAS Limited · Initial project enquiries
Protection and rehabilitation of existing concrete structures. POLY·VAS Limited is a technical project development company based in Nairobi, Kenya. Our technical ideas originated in Germany and draw on practical experience in several European countries.
We examine selected projects involving existing concrete tanks and containment structures. Our first objective is to understand the actual conditions and determine whether a technically suitable solution can be developed.
What is the problem?
Concrete damage has different causes. We need to know what is happening in the actual structure.
Existing tanks may suffer from chemical attack, cracking, leakage, corrosion or failure of earlier protective coatings. The cause depends on the construction, stored medium, environment and operating history.
What information do we need?
A first assessment requires facts about the structure and its operating conditions.
Please provide the location, dimensions, construction details, medium or stored substances, temperature, observed damage, photographs and available drawings. Earlier repairs, access conditions and the proposed work period are also useful.
Is a suitable solution possible?
Suitability cannot be determined before the project information has been examined.
Coatings, mineral systems, reinforced linings and thermoplastic solutions have different requirements. Depending on the structure and medium, another method—or further investigation—may be more appropriate.
What is TP·VAS?
TP·VAS is one defined method, not a universal answer.
It is a mechanically fixed PP-H composite lining system for existing concrete tanks. Its suitability, including material compatibility, anchorage and welded details, must be evaluated for each project.
How can we work together?
We can begin by reviewing available technical information and discussing the actual requirements.
If a viable approach is identified, further technical preparation may be considered. Cooperation with suitable independent local installation partners is possible only where project conditions allow it. No regional service network or solution is assumed in advance.
Submit project information
Send a short description and the information already available. An initial review will determine whether further evaluation is useful.
Include the structure, medium, damage, location and any drawings or photographs. Contact: info@poly-vas.com.
