The Power of Rust !
You've probably heard about wall tie corrosion; this photograph
illustrates a more dramatic situation which I found on a Building
Survey for a retail tenant.
The steel lintels in the building have corroded after long
term exposure to seaside air. Expansion of the metal
as it corrodes is lifting the brickwork on the top half of
the building. Eventually, the lintels will weaken and collapse
bringing down all the loose brickwork above.
The £30,000 cost of repairs would fall on the new tenant who
promptly pulled out of the deal.
