A comparison showing the advantages of modern techniques

Fast, safe, high-quality

Members of the ECS offer products that make building with concrete easier, safer and faster: in the case of fixing systems, products such as anchor channels ensure that elements are connected safely; lifting anchors facilitate assembly. Reinforcement for various areas of application not only makes concrete resistant to pressure, but also to tension. And the basis of a façade system for an appealing external envelope is formed by special fastenings for concrete, natural stone or brickwork façades.

Comprehensive information on each area of application can be found on the corresponding subject page. The advantages of modern construction techniques are summarised with comparisons.
