About Dost Group
Dost Group GmbH, based in Witten (North Rhine-Westphalia), has specialised in professional surface and protection systems for industrial plants since 2005. Its range of services includes the pre-production, finishing, repair and coating of wind turbine rotor blades, complete tower coatings, maintenance of offshore production facilities and oil rigs, as well as industrial climbing and rope access technology. Further business areas are maritime surface protection (blasting work, derusting, tank coating), yacht finishing for new builds and refits, industrial surface protection for industrial and chemical plants, floor and fire protection coatings, and temporary staffing with a focus on surface protection. The portfolio is complemented by drone inspections (including wind turbines, solar systems and high-voltage power lines via Lidar) with AI-supported evaluation, as well as IT and digital industry solutions. Projects are realised throughout Europe and in international markets such as Turkey, India, Mexico, the USA and Morocco. The materials processed are primarily GRP, steel and concrete.
