Dig modular antiinundatii PREFA

Simple assembly, fast protection

Flooding is always a natural phenomenon and cannot be prevented. However, modern flood protection can prevent this phenomenon becoming a disaster.

Optimum protection against extreme weather conditions with mobile PREFA flood protection! The special aluminium profiles are ideally suited to sealing windows, doors or gates effectively and protecting land or adjacent areas near to riverbanks.

Stop logs (to protect buildings and land)

The profiles are made from robust, corrosion-resistant aluminium alloy and are suitable for long-term storage, thanks to their low maintenance requirements. Two profile thickness versions are available (50 mm and 80 mm). Higher structures and greater span widths are possible with the 80 system.
The aluminium profiles can simply be stacked on top of each other in a tongue and groove system. The interlocking stop logs ensure high stability and maximum safety. The profiles are pushed into the fixing profiles on both sides and fixed in place from above with clamping elements. Profiles are available in lengths up to 6 m and can be installed up to a height of 3 m. Structural analysis is recommended in all cases. The system seal consists of EPDM / foam rubber and can be replaced easily when necessary. After use, ensure that the profiles and seals are cleaned and checked to ensure guaranteed functionality for future use.

Fixing profile (to protect buildings)

Solid fixing profiles can be mounted in three different ways: in, behind or in front of the jamb. The size of the fixing can be adapted to the structure as a whole, depending on structural requirements, and should be chosen individually for each case. The insertion of foam rubber seals stops water getting in.

Fixing supports (to protect land)

Weighs only 9,4 kg (50 mm system; 80 mm system - 11,3 kg) per running meter. Insert a ground sleeve in a suitable subsurface before initial installation. The supports are simply anchored into the ground sleeve via a bayonet socket, without any need for special tools. Additional bracing should be used if necessary.

Fixing support:
Diameter: 140 mm
Height: 600 - 2.190 mm
Versions: 50 or 80 mm thick.

Ground sleeve:
Diameter: 170 mm
Depth: 500 mm.

Two clamping elements are used to fix the logs in position from above Tighten the screws in the clamping element gently with a hexagonal spanner (alternative: screws with star-shaped head). The clamping elements prevent the profile from rising until the logs themselves fill with water, thus increasing the contact pressure of the seals. The clamping elements  can be removed at any time during use, in order to allow the system to be replenished.

Demountable flood barrier information

System

• 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 

Use

• 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

Possibilities

• 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.
