INNOVATIVE SELF-EXTRACTING FLOOD-BARRIER WITH eXtra
eXtra is a self closing barrier which creates a robust and solid solution against flooding. eXtra works on water pressure: Due to the pressure of rising water, the elements are floating out of their base pans. Whilst rising, the elements shut off the compartments water tightly.
A creation of Van Dijk Maasland and Grontmij.
