Structure upgrade and mastic asphalt
Developing fair solutions thanks to committment and the passion for buildings
Materials like concrete and steel are tried and tested components of buildings, the quality of which needs to be checked from time to time. We offer you precise damage analyses, state-of-the-art technology, and first-class materials to maximise the life cycle of your buildings. No matter if waterproofing, pavement, surface protection, or renovation: our custom-made, economic concepts ensure your project and make your building future-proof.
