At the end of the inspection, all material is compiled into a detailed inspection report with written notes, images and video footage. <\/p>\n\t\t<h2>\n\t\t\tAfter the inspection\n\t\t<\/h2>\n\t<p>After completion of the inspection, we deliver a complete report with pictures, video and clear recommendations. If necessary, we can immediately prepare a quote for the measures required to ensure optimal function and service life. <\/p>\n\t\t\t\t\t\t<h3>The inspection report contains<\/h3>\t\t\t\t\t\n\t\t\t<ul><li>General condition of the tank &#8211; walls, floor, partitions and structure<\/li><li>Presence of corrosion on sheet metal, pipes, flanges and fittings<\/li><li>Status of seals and joints &#8211; any damage or leaks<\/li><li>Need for cleaning &#8211; sediment, deposits or pollution in the water<\/li><li>Recommendations for action and preventive maintenance<\/li><\/ul>\t\t\n\t\t\t\t\t\t\t\t\t<img decoding=\"async\" src=\"https:\/\/cisternsolutions.eu\/wp-content\/uploads\/bb-plugin\/cache\/renovering-rostfri-tank-landscape.jpg\" alt=\"renovering-rostfri-tank\" itemprop=\"image\" height=\"600\" width=\"960\" title=\"renovering-rostfri-tank\" onerror=\"this.style.display='none'\"  \/>\n\t\t<h2>\n\t\t\tImportant when renovating a sprinkler tank\n\t\t<\/h2>\n\t<p>If the inspection shows that refurbishment is needed, it is important not to settle for anti-corrosion painting or a new liner. Such measures may hide damage temporarily, but will not restore the tank&#8217;s bearing capacity or structural strength. <\/p>\n<p>A proper refurbishment should always include rebuilding the structural steel to the same strength as when the tank was new. Weakened sections should be repaired or replaced before the shell is restored. <\/p>\n<p>Simply painting over rust gives a false sense of security &#8211; and in the worst case can put both the facility and people&#8217;s safety at risk.<\/p>\n<p>If you receive a proposal that only includes painting or liner, always get a second expert opinion. It could be the difference between a safe tank and a future risk. <\/p>\n\t\t<h3>\n\t\t\tWhy choose Cistern Solutions?\n\t\t<\/h3>\n\t<ul>\n<li>Inspection without emptying the tank &#8211; saving time and money<\/li>\n<li>High definition 4K documentation and sonar imaging<\/li>\n<li>Certified inspectors with extensive experience<\/li>\n<li>Clear reports and concrete proposals for action<\/li>\n<li>Focus on safety, sustainability and structural quality<\/li>\n<\/ul>\n\t\t<h4>\n\t\t\tContact us!\n\t\t<\/h4>\n\t<p>Want to find out what condition your sprinkler tank is in?
