Blow-Up Bulwark

We associate inflatable structures with ludic landscapes like the bounce castle and hippie hangout. Impractical technoutopias all. But for engineer Sigrid Adriaenssens and her Form Finding Lab, inflatables could offer a very practical response to the growing threat of storm surge flooding and the uncertainty of climate change. More air bag than pleasure dome, inflatable sea walls could be an affordable and flexible solution to protect coastal cities from rising tides. Adriaenssens and her collaborator Steven Strauss make the case below. Whether building a sea wall or replacing a neighborhood with a swale, soft and hard infrastructures both come with high costs and take a long time to put in place. Ready in three years and deployable in three hours, inflatable rubber barriers present a different direction for life on the water.
