Manchester Fibreglass Tank Lining These fibreglass tanks were imported from Italy. One of them arrived damaged and failed pressure testing before going into production. As fibreglass specialists, we knew we could carry out the repairs required, guarantee airtightness and get the tank back on line within days. The stressed areas were very visible from inside the tank. The 'spiders' were in random areas so it made sense to apply a reconstructive system to the complete wall/ floor area. We carried out abrasive sand blasting to the internal surfaces to create a good key for the localised fibreglass repairs and new fibreglass lining to adhere to. Layers of reconstructive fibreglass were applied to the stressed areas. When the repairs had cured, a chemical resistant double layer fibreglass lining system was applied to cover the complete internal surface area and reinstate the tanks integrity.
