Technical information
- 1. wall profile: Permanently built into the masonry or installed in front of, in or fitted flush in the reveal
- 2. barrier panels: Illustrated here: the lowest barrier panel is connected to point 3.
- 3. ground seal: Ensures sealing between the lowest barrier panel and the ground
- 4. centre column: In larger areas, these uprights can be used as intermediate columns.
- 5. compression clamp (with hex-head screw or with star-shaped handle): For clamping the barrier panels in place
- 6. retainer: Prevents vertical deflection of the barrier panels and increases pressure on the ground seal.
- 7. ground sleeve: Sleeve fixed permanently in the foundations with concrete for inserting the centre column
- 8. wall bracket: For stacking the barrier panels during storage when not in use
- 9. angular cover: For covering the wall profiles when not in use.
- 10. storage casing: The individual sections (length: 445 mm) are screwed together.
- 11. base profile seal
- 12. barrier panel seal
- 13. seal for cover and ground sleeve
barrier panels (property and perimeter protection)
The profile is made from a robust aluminium alloy and, as it requires very little maintenance, it can be stored for long periods without rusting. The profiles are available in three thicknesses (25 mm, 50 mm and 80 mm). Taller designs and wider span widths are possible with the 80-mm system. The aluminium profiles can be easily stacked together via the tongue and groove system. The insertion barrier panels ensure a high level of stability and maximum safety. Both sides of the profiles are inserted into the mounting profiles and fixed at the top by compression clamps. The profiles are available up to a length of 6 m and can be stacked up to a height of 3 metres. Calculating the static load is strongly recommended. The inserted system seal is made of EPDM foam rubber and can easily be replaced if necessary. After use, it is essential to clean and inspect the profile and seals to make sure that they can be used again in the future.
The PREFA flood protection system is available in three different thicknesses:

mounting profile (for property protection)
The permanent mounting profiles can be installed in three ways: in the reveal, behind the reveal, or in front of the reveal. The fastener dimensions are calculated on a case-by-case basis according to static requirements to suit the overall system. Inserted system seals made of EPDM foam rubber prevent water from penetrating.
mounting upright (for perimeter protection)
The 50-mm system weighs only 9.4 kg, and the 80-mm system weighs 11.3 kg per metre. When installing the system for the first time, a ground sleeve should be mounted in advance on a suitable supporting structure. The uprights are easily anchored to the ground sleeve by means of a bayonet locking device without the need for any special tools. Additional supports can be provided if necessary.

compression clamp (property and perimeter protection)
The panels are fixed at the top by two compression clamps. The compression clamp screws are gently tightened using an Allen key (alternatively: screws with a cross handle can be used). The compression clamps prevent the profile from rising until the panels fill with water, increasing the contact pressure of the seals. The compression clamps can be removed during use to allow the system to be extended, if required.

Questions and answers: PREFA flood protection
PREFA’s mobile flood protection in the aluminium barrier panel system is used to protect buildings and land. It is a reliable water and mud barrier even in extreme situations – from the Danube to the North Sea. Lightweight, robust and easy to assemble, aluminium barrier panels are stacked on top of each other in a tongue and groove system and inserted between two fastening profiles or uprights – in an emergency, they can even be installed by just one person.
The length is determined according to structural calculations and depends on the water level.
A flood protection system does not have to be 100% watertight. Minimal water ingress is acceptable. With the PREFA system, the aluminium profiles are stacked on top of each other in a tongue and groove system and inserted into fastening profiles or uprights on both sides.
