Fiber Glass Tank Sealing System

The system is a rehabilitation of fiber glass tank in case of any local crack, hole or similar damage. It is a local patch repair with fiber glass reinforced laminate layer. This sealing system rehabilitates the original tensile strength of the fiber glass tank.

Structure of the lining system:

Schematic of the fiber glass sealing system

Surface Preparation:

The surface shall be solid, clean, dry and free of any hydrocarbon residuals. The surface must be slightly sanded with sandpaper.

Sealing:

For each application a dew point distance of 3°C must be observed.

Primer:

For proper adhesion special primer must be applied directly on the cleaned and solid underground surface. The primer shall be applied with a roller.

Laminate:

The laminate system is a 2 component epoxy based laminate resin and a special biwoven ultra high strength fiber glass sheet. The laminate can be applied in 1, 2 or even 3 layers up to the damage and the customers demand. For laminate application use roller and previously cut fiber glass sheets.

Thigness Test:

After this patch repair the tightness of the tank must be tested.

Installation note:

The above information is based on tests by approved institutes (e.g. TÜV Süd Germany) and many years of experience. As the lining performance depends on correct installation, we offer application courses for certified installers and installation supervisors and provide certificates which shall be renewed every 3 years.
