Nuclear power plant

Our team protected sensors and cameras on safety equipment against seagulls at a large north German nuclear power plant. The seagulls often triggered false sensor alarms. We also closed the landing niches direct on the dome with large PE netting. Zips were built into the netting to allow regular maintenance work.

Airport hanger: netting with bonding technology

Birds were nesting in the hanger of an airport in south Germany and soiling the aircraft, with significant damage.  

Together with the customer’s installation team we bonded more than 2,000 m2 PE Antec netting. In addition, several thousand fasteners were attached to the cross bracings with high performance bonding agent. After sufficient drying time the very light netting could be hung in the fasters without any problems. The result is almost invisible netting.

Brewery silos: extensive netting

Several flocks of pigeons were spread out on and between the silos of a large brewery. The result wa heavy soiling and nesting between the silos.   

We installed more than 1,000 m2 of netting with cable technology. Access is possible through zips. Industrial climbing technology was used for the installation.

Inner courtyard: netting with industrial bonding technology

Large inner courtyards can be gateways for pigeons. The installation of large netting is not easy in these cases. Scaffolding must be removed first – if the netting is already hanging, it is no longer possible. How can the netting be fixed?

In the two large courtyards we used industrial bonding technology. Our climbers carried out the work with flair. As you can see the netting not only keeps the pigeons away, but also the remains of the workers’ breakfasts.

Hydroelectric power plant: netting

Netting was fixed over the forecourt of a hydroelectric power plant in Würzburg. The netting is hardly noticeable due to the choice of colour and mesh size.

Church of St. Martin Bingen: netting

Church towers are often an attraction to pigeons and other birds. The famous Church of St. Martin in Bingen attracts not only pigeons but also larger birds from the Rhine valley. Heavy soiling of the bell tower and the bells was the result.

Our industrial climbing team cleaned the pigeon droppings and disinfected. The sides of the bell tower were then netted. The pigeons could no longer get into the bell tower; this meant predators were no longer attracted to the flocks.

University Clinic: netting with bonding technology

There are skylights controlled by the air conditioning in the reception area of this university clinic, they open and close automatically. The pigeons discovered this spacious area and flew in when the skylights were open.  

The challenge was to install netting with as little damage as possible, and also not in the way of the opened skylights. We realised this by bevelling the netting. The bonding technology was very suitable for this project.

Stadium in Luxemburg: polyethylene netting

We installed large area netting underneath the grandstand of the Ettelbruck stadium. The zip access in the netting enables maintenance to be carried out on the lighting under the roof.

Inner courtyard Frankfurt: netting

We installed netting using cable frame technology in the inner courtyard of a bank in Frankfurt. Pigeon dropping also had to be removed and disinfection carried out.

Deutsche Welle, Bonn: netting installation

An open staircase leading to the Park provided shelter and roosting to pigeons. We installed large netting to prevent them flying in.

Swallow netting: PE netting with bonding technology

With a contract from the Cornelia Hopf property management company we installed preventative swallow protection on the facades of these properties.

The netting is strectched between the guttering and house walls. By using PE Antec netting with bonding we were able to avoid boring special dowels through the insulation. A major advance, due to which time was saved and costs were lower to the client.

Suspended facade: stainless steel netting

The concrete segments of this suspended facade provided pigeons with many roosting possibilities. As a result the facade and in particular the window sills were soiled by pigeons, some even brooding.  

The pigeons were successfully driven away by the installation of stainless steel netting.

Chemical plant North Rhine Westphalia: PE Antec netting and strip curtains

Chemical plants are usually open on all sides and provide birds with many nesting possibilities. We installed netting with bonding technology and strip curtains at a large chemical plant in NRW.

The area is still accessible to the employees.

Inner courtyard Dresden: netting using industrial climbing

Pigeons infested the inner courtyard of a new building opposite the famous Church of Our Lady in Dresden. Due to the difficult access we installed the netting using industrial climbing technology.

Bonding the netting also proved itself here. A steel cable frame attachment would have been very complex as the facade also functions as insulation.

Church in Allenbach: Cleaning of pigeon droppings and netting

This evanglic church in Allenbach is more than 200 years old. The window laths of its steeple were broken, allowing pigeons to fly in and breed for many years.

The droppings of the birds were immense. It was not possible to enter the roof structure without protective suits and breathing masks. We have cleaned and disinfected the whole roof from the droppings according german method BGI 892. To protect the roof from the birds, we have netted all windows of the steeple with our specially flame-resistant PE-net.

Bremen Cathedral: Nettings

During the renovation of the Bremen Cathedral, the existing bird control measures had to be renewed.

We have netted roundels and access balconies of the church with stainless steel nettings.

Mainz Fortress: Netting

During the renovation of the Mainz fortress, the portal and emblem were recreated and freshly coated. As a bird control method, spikes had been used, which had to be taken off before renovating. The spikes turned out to be quite inefficient, since pigeons were breeding behind them.

The house owner preferred a complete netting using bonding techniques. Drillings became unnecessary and the netting itself could be attached very closely to the architectural structure.

Goettingen Hospital: PE-netting Antec

Especially for hospitals hygiene is of extreme importance. Bird and pigeon droppings must be prevented with all means.

At the Goettingen hospital, stainless stell pipes are being used as snow guard. To prevent pigeons from roosting, we have installed a special stainless stell wire-system.

Beneath the roof pigeons also roosted directly on the tiles, since this place is best sheltered from the wind. We have installed PE-netting Antec, glueing it directly on the tiles.

Stainless stell spikes on roof ridges and ledges make bird control on this building complete.

Altenberg Cathedral: Nettings and Wire System

The Altenberg Cathedral of the Cistercians receives pigeon visits quite often. They like to sit on the overhanging ledges of the window ornaments, which is a common place for pigeons on churches - especially at wind-protected parts of the building.

We have protected the ornaments with a netting of the upper part. The cross-bracings above that window had many pigeons too. There we have used a special pipe clamp wire system.


A4 Federal motorway bridge at Jena

We installed more than 100 square metres of polycarbonate plates as bird protection underneath the Podelsatz Bridge near Jena.  

After an exact survey we prepared plans and cut the material accordingly. All the plates were installed at a height of over 30m using industrial climbing technology, thus saving substantial costs on bridge bottom view equipment. To enable planned maintenance purposes in future most of the plates have additional handles and can thus be easily removed. The high specification of the fastening material ensures the long-term quality of the bird control measure, which is almost invisible due to the material selected.

Niederwartha Bridge: netting and spikes

The Niederwarthaer bridge at Dresden is a modern cable-stayed bridge with a main opening of 192m. The existing parallel railway bridge is heavily infested with pigeons. Therefore, the client decided on extensive bird control measures.  

The underside of the steel structure has a complex geometry, why a bird intrusion measure with grating or expanded metal would have been very complex. Our netting with bonding technology provided an excellent suitable alternative. It can cover large areas and is cheap to install, without damaging the structure by drilling. More than 2,000 square metres of 18mm x 18mm PE netting was installed by bonding on the steel structure and abutments. The netting is held in place by more than 5,000 plastic fasteners, which are attached to the structure by special adhesive.  

Likewise, the cable anchors are favourite roosting places for pigeons. Special stainless steel spikes prevent this. They were also installed on the drainpipes, the upper edges of the pillars and the pylon.

B404 Elbevorland Bridge Geesthacht

The abutments and pressure plates on the bridge at Geesthacht were protected by us. Our team installed ca. 200 m2 GRP (glass fibre reinforced plastic) grating. Gratings, made of V4A binding agent and specially manufactured posts, were cut using laser technology and assembled after detailed planning and 3D modelling.  

In one of the V4A frame constructions grating was installed as a door, to allow easy access to the pressure plate. GRP gratings are light and stable, economic, and enable dependable rear ventilation to the bridge components, compared to other solutions.

Bridge near Bonn: PE netting in bonding procedure

We cleaned and disinfected a heavily soiled abutment on this bridge near Bonn.  Bird control was with PE netting Antec and bonding technology.  Thus, there are no drill holes in the structure. Zips were included to ensure access to the abutments.

Federal German Railways, Frankfurt: Netting

We protected the abutments of the bridge pillars with PE netting on the German Railways bridge. Zips were included to ensure access for maintenance purposes at all times.

Federal German Railways: pigeon droppings cleaning and disinfection

Bridges are often used by pigeons for sleeping and breeding. They are thus often heavily contaminated.  We removed and disposed of several tons of pigeon droppings in accordance with Health and Safety Executive Regulation 892 from this bridge. After disinfecting the bridge was reopened for tests.

In the Wetzlar area: cleaning and disinfecting underneath bridges

There were heavy pigeon droppings soiling the underneath of this bridge. All work was carried out with the strictest protection measures for our employees. The pigeon droppings have been disposed of in accordance with the Hazardous Waste Regulations.  

After two disinfections it was possible to carry out the bridge testing.

In the Wetzlar area: netting underneath bridges

At this motorway bridge in Hessen we had to protect the entrances, which were heavily contaminated with pigeon droppings, from bird intrusion. The entrances and abutments were protected with several hundred m2 fine mesh PE netting using cable frame technology.

Duisburg: closing of entrances on the abutment

The entrances on the abutment of this bridge on the B57 in Duisburg were closed with polycarbonate plates. It was not possible to completely close the entrances with plates, so the remaining open area was closed with bonding technology. The pigeons found this open area and quickly repopulated the rear of the abutment making a second cleaning and disinfecting necessary.

Hessen: closing of entrances on the abutment

We closed the entrances to the abutment of this bridge with stainless steel netting. This method of installation is time-saving and cost effective due to the high inherent stability of the netting.

Duisburg: PE netting Antec in bonding procedure

Under this bridge on the A59 in Duisburg abutements are protected with steel gratings. The gratings didnt reach the under edge of the bridge, leaving place for pigeons to breed.

With PE netting Antec and bonding technology we have securely protected these openings. Antec-nets can be flexibly attached to any structure, although costs are much less compared with those of gratings.

Cologne: Stainless steel spikes on drainpipes

Under this bridge in Cologne, we have installed stainless steel spikes directly on the drainpipes.

Wire systems

State Museum of Mainz: stainless steel wire system

In the framework of renovating the State Museum of Mainz parapets and surrounding beams were protected with a multiple row wire system. The multiple rows of the system ensure complete protection and prevent birds from settling in the open space behind a shorter system.

Klauser Wuppertal: stainless steel wire system

Our proven stainless steel wire system effectively prevents bird intrusion. A three row system was selected to protect the attics and window sills. Corner pieces ensure all-round protection.

University of Düsseldorf: stainless steel wire system

The wire system protects the edges of the attics from bird intrusion. A three-row system was chosen.

Exhibition Hall Frankfurt: Special Product Stainless Steel Wire System

The entrances of the new Exhibition Hall 11 in Frankfurt are suitable for pigeons flying in. In particular, the birds roost on the air conditioning directly behind the facade.

The challenge was to develop a system that on the one hand functions and on the other integrates harmoniously with the optical characteristics of the building.

The result is a multi-row stainless steel wire system that is anchored sideways in the soffits.

Waste management company: wire system as shield

For handrails stainless steel wire systems can be successfully installed as a shield. A risk of injury does not exist.  

We have installed a shield system on several storeys of the Bonn waste management company.

Church of St. Martin Bonn: stainless steel wire system and netting

Older structural substance can also be effectively protected: a stainless steel wire system was attached to the guttering here.

Inner Courtyard Dresden: Stainless Steel Wire System

Pigeons like to populate city centres. This was also the case in the centre of Dresden, where we protected the parapets of a new building opposite the Church of our Lady with several rows of stainless steel wire system.

Wire systems have a very high efficiency and are, not least because of the good visual effect, suitable for repelling birds.

Goettingen Hospital: Wire-system

Especially for hospitals hygiene is of extreme importance. Bird and pigeon droppings must be prevented with all means.

At the Goettingen hospital, stainless stell pipes are being used as snow guard. To prevent pigeons from roosting, we have installed a special stainless stell wire-system.

Beneath the roof pigeons also roosted directly on the tiles, since this place is best sheltered from the wind. We have installed PE-netting Antec, glueing it directly on the tiles.

Stainless stell spikes on roof ridges and ledges make bird control on this building complete.

Electrical systems

Egana Goldpfeil Offenbach: profile electrical system

Pigeons had nested in the inner courtyard of a branch of Egana-Goldpfeil in Offenbach – a sign of colonisation. An electrical system installed on the roller blinds box and the window sills solved the problem.

Office building Karlsruhe

An electrical system compatible with the expensively renovated facade was selected. The facade was not visually impaired – efficiency was very good.

E.On Düsseldorf: electrical system

The goal at the head office of E.On and the E.On Academy in Dusseldorf was to keep the roof cornices, the roof ridges and the entrance area free of birds. We successfully installed the TAPO profile electrical system here.

E.On hydroelectric Würzburg: electrical systems

The historic listed monument and architecturally valuable hydroelectric power station in Würzburg had to be carefully protected against pigeon droppings. The TAPO profile electric system was selected, together with a special clamping system for the snow guards.

An extensive forecourt was also covered with netting.

Chamber of Commerce Bremen: Electrical system Columbex

The building of the Chamber of Commerce in Bremen is several hundred years old and a listed building. Its location in the centre of the town right at the market, exposes it directly to pigeons. Top quality ornamentation and its sandstone construction urge for an effective bird control.

Therefore, the owner decided in favor of the electrical system ColumbEx, which we glued on the surface with special primer and adhesives. We also protected the ornaments with the system, which is flexible and can be adjusted to every curve. We have met the high expectations of the owner, the requirements of the monument conservation and bird control.

University Campus Munich Martinsried: electrical system

We installed over the reception area of the new building of the University Campus Martinsried the TAPO profile electric system. In close cooperation with the architects, the planners and TONI the client finally decided on the anthracite coloured version of the system.  

The current source was installed in a separate high quality terminal box, which was specially coated in the colour of the facade. Due to the excellent colouring the pigeon deterrent was almost invisible.

Housing in Cologne: Electrical System

This inner courtyard of this new housing was protected with an electrical system against pigeons. The system is installed in the front attic in an area that is not easy to reach. Therefore, the occupants, children etc cannot  reach the system and frighten themselves.

Electrical systems are particularly effective because there is no habituation effect and they are optically discreet. They are also just as suitable for private accommodation.

Wehmeyer Giessen: electrical system

At the Wehmeyer department store in Giessen we installed the TAPO profile electrical system as arris protection.

The parts of the building that were difficult to reach were protected by spikes.

Frankfurt, Zeil: TAPO profile electrical system

Pigeons often use protruding glass- or sunawnings to perch. Many pedestrians and customers have had an unpleasant surprise.

We installed the TAPO profile electrical system on the glass roof to prevent this. The light boxes of the advertising were connected to the electrical supply.

Talos1 / Combination system

Facade in Karlsruhe: Electrical System

We installed our combination system on this facade in Karlsruhe to protect the parapets. The system can function as a pure wire system or – with electricity – as an electrical system. We installed it as an electrical system on the facade in Karlsruhe.

For this purpose we assembled and fixed one after the other and under each other several segments – each of three stainless steel wires. Each segment protects ca. 18 – 20 m parapet. Direction changes at edges were achieved with oblique profiles.

The system could protect several hundred metres from pigeons on this facade at an attractive price. By the use of solar energy the system is completely self-sufficient.

Flat Roof-Parapets: Electrical System

On one of the largest warehouses in Europe there was heavy contamination caused by large birds roosting on the parapets.

The customer decided on our combination system as it is suitable for nearly all birds, but in particular the larger birds here. There is also no habituation by the birds due to the electric feed, similar to the meadow wire principle.

In total we have protected more than 500 m of parapet each with three parallel electric wires.  The installation rails were set so that a rail was only necessary every ca. 20 m. We realised the power supply with solar energy, so that the system is completely self-sufficient.

Optically the system is discreet and does not impair the appearance of the clearly articulated facade.

Nuclear power plant: Electrical system

Its location makes the nuclear power plant in Stade very attractive for sea gulls. The dirt at the facades of the buildings around the reactor are quite enormous.

We have installed several hundred meters of our wire-electrical combination system at the attics of several buildings. Because of its construction, the system is suited much better to control gulls than other electrical systems. Habituation is almost impossible. Facades do keep much cleaner now.


Facade in Frankfurt: stainless steel spikes

During renovating we cleaned and disinfected the facade from pigeon droppings. Stainless steel spikes were discreetly installed for protection.

ETG Frankfurt: stainless steel spikes -installation

Guttering is a bird favourite. Special spikes helped here. These went so far into the recess that the birds could no longer nest in the guttering.

Cologne: Stainless steel spikes on drainpipes

Under this bridge in Cologne, we have installed stainless steel spikes directly on the drainpipes.

Goettingen Hospital: Stainless steel spikes

Especially for hospitals hygiene is of extreme importance. Bird and pigeon droppings must be prevented with all means.

At the Goettingen hospital, stainless stell pipes are being used as snow guard. To prevent pigeons from roosting, we have installed a special stainless stell wire-system.

Beneath the roof pigeons also roosted directly on the tiles, since this place is best sheltered from the wind. We have installed PE-netting Antec, glueing it directly on the tiles.

Stainless stell spikes on roof ridges and ledges make bird control on this building complete.
