The Anhamm Spillbarrier is an automatic flood barrier that provides a specially designed solution for the retention of floodwater, heavy rainfall and other uncontrolled volumes of water. Its purely mechanical operation ensures maximum safety - completely independent of electrical or hydraulic energy sources.

First, incoming water is completely absorbed by all openings in the Spillbarrier.

The Spillbarrier is triggered by the water collecting in the Spillbarrier tray and floats up.

Finally, springs fold the Spillbarrier into an upright and tightly closed position.

Answers from our product specialists.
At the customer’s request, we can install a limit switch in the post of the folding bulkhead, where the customer can have an approved electrician connect a flashing warning light or an acoustic warning signal, for example.
Minimum seal height is 300 mm. From door width to customer requirements. The longest width produced to date was 47 m with a sealing height of 1 m. The passage width is not interrupted, it is fully usable. The maximum height is now 2.40 m and we are constantly developing in this area as well. Anhamm Spillbarriers are manufactured to customer specification.
No, we adapt the design of the Spillbarrier to suit the conditions on site. We can build into any slope.
The Anhamm Spillbarrier is currently the only spillbarrier that can be lifted manually without much effort, using a tyre iron at most. The weight of the flap is reduced by the pre-tensioned springs. The flap must be lifted briefly by hand to the pivot point and swings automatically into the closed position. Once the flap has been raised, the barrier tray can be cleaned and returned to its original position by hand.
