Retrofitting Old Buildings: Making Structures Safe Again

Retrofitting Old Buildings: Making Structures Safe Again

Retrofitting is the process of strengthening an existing building so it can safely carry current loads and resist earthquakes. It extends the life of a structure without full reconstruction.

Why retrofit?

Many older buildings were designed to outdated standards or have deteriorated over time. Retrofitting brings them up to modern safety levels.

Common retrofitting techniques

  • Concrete or steel jacketing of columns and beams
  • Adding shear walls or bracing
  • Foundation strengthening
  • Fibre-reinforced polymer (FRP) wrapping

The retrofitting process

Assessment first
