We recommend a yearly service on all our gates by our qualified service engineers to ensure the gate is in full working order. This is to make sure the gates are fully operational in a possible flood event and that they are free from any obstruction or any vandalism. As our floodgates are very low maintenance, they require a quick check of the seals for compression and a grease of the hinges, mechanism’s require a visual check and an application of penetrating oil (WD40) and a trial deployment A lot of our client’s insurance companies are now insisting on this.
