Living in a flood prone area can make a simple thunderstorm a pretty stressful experience. While sandbags are one option for protecting one’s home or business, Hydroguard is a mechanism that seems far easier to use and potentially more effective. The sliding barrier includes a unique sealing technology that is supposed to allow the flood water damage preventer to fit any doorframe within minutes, and it’s reusable. It’s not clear how many feet or meters the flood blocking gadget can keep out, but for £199 GBP, early bird backers get one product, with an expected delivery of March 2015. The expected retail is £249.
