Internal Reinforcement
• Vertical reinforcement
• Tying key elements
External Retrofits
PP-Band Technology
•Polypropylene (PP) strapping
•cheap and readily available
•Prevents brittle collapse and
loss of debris

Nepal
• No engineering input
Rural Kathmandu
> 95% masonry•
Nepal - Dissemination
Peru
• Major earthquakes
in 2001 & 2007.
• Rural areas, again,
have no engineering
input.
External Steel Mesh Reinforcement
• 360 new houses
• Several public
buildings
Arequipa Reconstruction Programme - 2001
8 years on…
• Many lessons lost
because not used
often.
Next Steps?
Thank you for listening.
Any Questions?
