FLOOD PROTECTION SOLUTIONS DEMOUNTABLE FLOOD BARRIER
- Demountable flood barrier made of aluminium
- Sealing the profile with replaceable UV-resistant EPDM foam rubber seals
- Provides protection as soon as the first panel has been laid
- Aluminium barrier panels are pushed into the mounting profiles or upright (anchored in the ground sleeves)
- Barrier panels are stacked on top of one another via the tongue and groove system
- The components are fixed at the top by a compression clamp
- The barrier panels fill up as the level of the water rises, preventing them from floating
- Property and perimeter protection
- The length of the safety barrier can be extended as necessary
- Existing safety barriers can be extended following a static test
- Individual adaptation of the length of barrier panels
DEMOUNTABLE FLOOD BARRIER – TECHNICAL INFORMATION

BARRIER PANELS (PROPERTY AND PERIMETER PROTECTION)
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|

MOUNTING PROFILE (PROPERTY PROTECTION) AND UPRIGHT (PERIMETER PROTECTION)
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.

COMPRESSION CLAMP (PROPERTY AND PERIMETER PROTECTION)
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.

|Compression clamp weight:||0.45 kg|

DEMOUNTABLE FLOOD BARRIER – POSSIBLE USES
With the special aluminium barrier panels, windows, doors and door openings through which water can penetrate can be quickly sealed off.
- Permanent mounting of the mounting profiles flush with, or in front of, the reveal.
- When used in the event of flooding, the barrier panels are pushed into the fastener and fixed at the top with a compression clamp.
- Mounting profiles and barrier panels can be colour-coordinated with the façade.
- Rapidly deployable, ideal for storing and easy to install individually with very little effort.
- Safety barriers can be used as new constructions or to increase the height of existing protection systems.
- When used in the event of flooding, the centre columns (supports) are anchored into the sunken ground sleeve and the barrier panels are then inserted. After use, everything can be easily removed again. Ground sleeves can be sealed with cover plates.
- The safety barrier can adapted to the final level of the water at any time.
