HydraStone provides onsite internal / external inspections of tanks and pipes to determine the basic condition of the substrate and existing lining. If inspection reveals damaged lining or substrate future recommendations will be provided. If severe corrosion is found non-destructive testing may be recommended along with a full written report complete with pictures and future work to be completed. When dealing with large companies or government institutions which have numerous tanks, located quite often at more than one location, we have found the best way to begin is to prepare a complete inventory. External inspections will be completed for each site at no charge to develop a chart that will specify all tank sizes, location, external condition and any information that can be retrieved from attached nameplates. This information will be given to the customer with future recommendations and associated cost to complete listed work.
