Before: Concrete Delamination
Upon completing a non-intrusive cover meter survey and a carbonation test; it was discovered that the second beam – which would endure heavy use – required strengthening to support the loads. The results showed noteworthy corrosion to the existing footbridge while the columns demonstrated steel corrosion and delamination of the concrete. To reinforce the steel a corrosion-inhibiting protective mortar was utilized before the concrete could be repaired.
This was followed by the installation of Mapeband – a high-strength carbon fibre fabric – to the 14LinM of beams and columns to strengthen and reinforce them. A 2mm coat of Mapelastic Guard was applied to all surfaces to provide effective anti-carbonation and anti-corrosive protection to the structural elements.
