The stresses on the concrete are tremendous!
large changes in temperatures across the seasons and within just a few hours (sunshine following freezing nights) affect severe thermal changes in length; significant tensile forces through snow, wind and cables stress the statics; permeating moisture initiates the carbonisation. Fissures, spalling, torsion damages and corrosion are inevitable consequences.
If the refurbishing is meant to produce lasting success, the applied materials need to be optimally adapted to the physical properties of the concrete. This is where the products of VIASAN series come into play: epoxy resins and pure acrylates that were specifically developed by us and tested for their long-term use.
