Underground Water Tank Lamination


What is the need for GRP Lamination of Underground Water Tanks?
Underground water tanks may suffer from weep, seep, or leak behavior depending upon manufacturing
quality, handling during installation, operating extremes, degree of monitoring and inspection, and the
effects of wear over time.
All underground water tanks must meet specific regulatory requirements to be protected from the
environment. Steel and concrete water tanks require secondary containment as a means of corrosion and
leak protection, whereas GRP lamination can be applied as an internal coating and external overlap. GRP
water tanks have higher corrosion resistance and the need for maintenance is very low compared to other
How is Underground GRP Water tank Lamination done?
Surface preparation work would be carried out by removing any loose particles like dust, oils, grease, etc.
before laminating the underground water tank. All corners of the tank are made to be curved before GRP
lamination, and the process of GRP lamination is carried out in a sequence of the ceiling, then the wall,
and finally the floor. The first layer of putty filling is done after cleaning the surface, and then resin
coating is applied as an undercoat.
How can we select the Right materials for GRP Lamination of Underground Water Tanks?
Developments in resin technology have resulted in several case histories of the successful use of GRP in
hostile environments. GRP manufacturers have a lot of data that helps to identify which type of
resin is suitable for a particular environment. The Resin systems can achieve different maximum
operating temperatures, and accurate selection of the resin system helps GRP lamination to provide
resistance against a wide range of temperatures. Correct selection of resin should ensure that the GRP
laminated underwater tanks perform
satisfactorily at the specified temperature.
What are the Signs, which Indicate the need for GRP Lamination of Underwater Water Tanks?
Signs of degradation can be detected during a visual external examination, that includes various
parameters such as,
● The difference in surface condition
● Thinning of the surface material.
● Cracks
● Delamination
● Discoloration
● Colored spots
● Liquid droplets permeating the surface
GRP lamination of underground water tanks prevents leakage and absorption of water, thus preserving
water from all forms of contamination and helping to protect the tank from extreme weather conditions.
