Flooding is a natural phenomenon and cannot be prevented. However, modern flood protection systems can prevent flood water from causing a disaster. We would be delighted to advise you about PREFA’s flood protection systems!

The panels are available in two thicknesses (50 mm und 80 mm). Taller designs and wider span widths are possible with the 80-mm system. The aluminium profile of the panels can be easily stacked together via the tongue and groove system. This ensures that they interlock, guaranteeing high stability and maximum security. Finally, compression clamps fix the whole assembly in place.
The profiles are available up to a length of 6.5 m and can generally be built up to a height of 3 metres. The static load must be calculated. 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.
|Barrier panel thickness (50-mm system):||50 mm|
|Barrier panel thickness (80-mm system):||80 mm|
|Barrier panel weight/metre (50-mm system):||5.60 kg / 4.12 kg|
|Barrier panel height (50-mm system):||150 mm / 200 mm|
|Barrier panel joint (50-mm system):||15 mm|
The permanent mounting profiles can be installed in three ways: in the reveal, flush with the reveal, or in front of the reveal. Choose the mounting profile size suitable for the overall system and according to static requirements. Inserted system seals prevent water from penetrating.
Mounting uprights: 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 can be easily anchored to the ground sleeve with a bayonet locking device.
|Centre column diameter:||140 mm|
|Centre column height:||50–2150 mm (special lengths available on request)|
|Centre column thicknesses:||50 mm or 80 mm|
|Ground sleeve diameter:||170 mm / 230 mm|
|Ground sleeve depth:||420 mm|
The panels are fixed at the top by compression clamps. The compression clamp screws are gently tightened using an Allen key (alternatively: screws with a cross handle). The compression clamps prevent the profile from floating until the panels fill with water, increasing the contact pressure of the seals. The compression clamps can be removed during use – and more panels can be added to increase the system if necessary.
With the special aluminium barrier panels, windows, doors and door openings through which water can penetrate can be quickly sealed off.
