EF carryout a large number of process water tank restorations,this is due to an " out of site, out of mind" policy by many industries, leading to corrosion problems. Around 50% of process water tank refurbishment are due to leakage problems. EF repair the perforated areas using riveted corrosion proof plates and fibreglass, finishing off with a Epoxy Coating to prevent further corrosion and leakage problems. EF offer a ten year year guarantee.
