A HIGH-WATER PROTECTION MEANS COMPRISING A WATER INSOLUBLE NON-SWOLLEN BUT IN WATER STRONGLY SWOLLABLE MATERIAL

摘要

1. Flood protection, characterized in that a casing contains a polymer which is insoluble in water and swells intensively in water, in a form in which at least one dimension is small enough to ensure a rapid intake of water and that the permeability of the casing in fact enables a fast penetration of water, but prevents the unswollen polymer from falling out.
