Water flowing into an Anhamm Spillbarrier, which activates automatically without electricity

Water Spillbarrier - Flood Protection

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.

Fully automated flood and heavy rain retention

  1. Spillbarrier at rest, installed flush with the floor
    Step 1

    Fluid intake

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

  2. Spillbarrier as the barrier begins to rise
    Step 2

    Automatic release

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

  3. Spillbarrier fully raised and sealed
    Step 3

    Seal & retain

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

Technical safety, design and optional signaling

Certified safety even under extreme impact loads

Successfully tested to the FM-2510 water flap gate test: a specially prepared timber beam was directed at the upper center of the system - result: passed without relevant deformation or impermissible leakage. The watertight seal and structural integrity remained intact. This performance supports reliable use as an automatic flood & spill barrier where debris impact can occur.

Custom color finish on request

Custom wrapping in your preferred color (building design, corporate identity, or safety marking). Premium branded films (ORACAL®, Avery Dennison®, 3M™) support a durable, weather-resistant finish - ideal for industrial environments and spill containment system installations.

Audible & visual signaling

Optional audible/visual signals provide clear indication when the barrier activates - improving operational transparency during a spill event.

  • Signals: audible and/or visual - available for all barrier variants.
  • Integration: connection to existing alarm/building systems possible (mechanical pull-cable switch; electrical integration by the customer on site).
  • Smart notification: optional, project-specific (higher planning/cost effort).

FAQ

Questions about the Water Spillbarrier

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.
