Bird Balls & Cover Balls from EURO-MATIC
Floating cover balls – known as "Bird Balls" – offer an innovative, effective, and sustainable solution for covering water surfaces. They reduce algae growth, prevent the spread of duckweed, minimize evaporation losses, and protect birds from drowning – especially at airports. EURO-MATIC supplies these industrial-quality balls – TÜV-certified, durable, UV-resistant, and environmentally friendly.
Why Bird Balls?
- Prevent algae growth and duckweed by light shielding
- Reduce evaporation by up to 90%
- Reduce bird strike risk at airports
- Stabilize water quality in retention basins, sewage treatment plants and reservoirs
- Maintenance-free & durable – up to 10 years of service life
Effective protection against duckweed and algae
Algal blooms and duckweed (Lemna) are often caused by excessive nutrient input and intense sunlight. The consequences: oxygen deprivation, unpleasant odors, hygiene problems, and even the watercourse's erosion. Bird Balls block up to 99% of the sun's rays, depriving algae and duckweed of their vital resources – without the use of chemicals or mechanical intervention.
Bird control and airport security
Open bodies of water near taxiways or runways attract birds – with fatal consequences. Birds can become trapped in aircraft engines during takeoff or landing (bird strikes), leading to dangerous incidents worldwide. Bird Balls make bodies of water unattractive to birds: The balls move, reflect light irregularly, and prevent them from landing – without harming the birds.
Further applications
- Rainwater retention basins & open water reservoirs
- Industrial tanks with chemicals
- Wastewater treatment plants & biological basins
- fire water tanks
- Water collection basins in the food and pharmaceutical industries

Can Bird Balls save animals?
- Yes, especially at airports, Bird Balls prevent birds from landing on water and drowning. This reduces both animal welfare problems and risks to aviation.
How many balls do I need per m²?
- For complete coverage, approximately 250–300 spheres (depending on size) are required per m². EURO-MATIC provides customized support with the calculation.
How long do the balls last?
- The balls are designed to last up to 10 years – even under direct UV radiation and chemical stress.
