Resilience Measures for Built Environment- Summary



main characteristics

techniques used


Dry Proofing



The building is sealed i.e. the external walls are used to hold back the flood water

Sealing against pressurised water (water resistant concrete “Weiße Wanne”, polymer bituminous seal “Schwarze Wanne“)

Additional sealing against non-pressurised water (horizontal, vertical)

Protection (sealing) of the openings

Installing non-return valves (anti-flooding device) within the private sewage system as a protection from the sewerage backflow



The floodwater does not reach the building itself. Barriers are installed at some distance from the building or a group of properties

flood barriers, flood skirts







Controlled flooding of building using water resistant materials

Flood damage potential of a building is reduced by applying water resistant materials. Due to economic or technical reasons, the lower parts of the building (basement) is partly flooded and not used for living. At the same time, the ground floor can be dry-proofed.

e.g. water resistant paints and coating, lime based plaster, plasters of synthetic resin, mineral fiber, insulation tiles, oil based paints

adapting the occupancy of the building

raising the inventory, heating tanks and electrical appliances above the expected flood level


Elevating the inventory

Using easily removable pieces of inventory in lover parts of the building

e.g. removable furniture (e.g. with wheels), rugs rather than fitted carpets
