Our team has more than 10 years of experience in various international projects. The countries of deployment include Germany, Brazil, Israel, South Africa and Georgia.


We have extensive experience with hydroacoustic surveys and sediment investigations. We combine hydrography with sedimentology and ecological understanding of the sediment and nutrient balance of water bodies and develop economic solutions for your water management.


We speak seven languages (German, English, Albanian, Portuguese, Spanish, Greek and Italian) and can therefore handle international projects excellently and solve logistical challenges.
