Concrete repair – simple and reliable
Specifically, carrying out concrete repairs straightforwardly, quickly and reliably means using only one product. The material provides corrosion protection, good adhesion means that a bonding bridge is not required and the elevated fines content means that the surface can be smoothed in a similar way to a filler. Areas of application are conven- tional building construction and also light-weight concrete objects. KEIM Concretal- Universalmörtel-S – one product for every job.
