Further information


The following examples show possible applications of the Prefa flood protection dam locks in the field of building protection and landscape protection. The flood protection can also be installed over long distances.

Dam beam tongue and groove

Dam beam tongue and groove system

DAMBARKEN (property and landscape protection) The profile is made of a robust and corrosion-resistant aluminum alloy and is also suitable for long storage thanks to the low maintenance requirements. The profiles are available in two thicknesses (50 mm and 80 mm). With System 80, taller constructions and larger spans are possible. The aluminum profiles are simply stacked on top of one another in a tongue and groove system. High stability and maximum safety is guaranteed by the interlocking of the dam beams. The profiles are pushed into the fastening profiles on both sides and fixed from above with clamping pieces.

Fastening in front of or in the reveal

Object protection fastening profile - in or in front of the reveal

FASTENING PROFILE (for property protection) The fixed fastening profiles can be connected in three ways: In, behind or in front of the reveal, as described above. The fixing is dimensioned according to the static requirements to match the overall system and must be decided on a case-by-case basis. Inlaid system seals made of foam rubber prevent the ingress of water. The profiles are available up to a length of 6 m and can be installed up to 3 m high. A static calculation is recommended in any case and we also offer it without obligation and free of charge. The inserted system seal consists of EPDM / foam rubber and can be easily exchanged if necessary. After use, the profiles and seals must be cleaned and checked in order to guarantee functionality in the event of future events.
