Low Tech Magazine has an article on fascine mattresses, historically used for inpoldering in the Netherlands, and I noticed that the technique is still in use in modern construction https://solar.lowtechmagazine.com/2021/11/fascine-mattresses-basketry-gone-wild.html
@th Thanks for that article! Seeing the enormous negative climate impact of the now ubiquitous concrete (worse than all co2 emissions of transport), it could be a good alternative for the future. And keep the Netherlands dry.
@th They should be quite happy there. It may remind them of the swamps of Sqornshellous Zeta.
