Quoting: Incursus
For a time capsule I think a common car like the Ford Mondeo....
That would be no good, they need something that hasn't already started to rust...................
I love this sort of news item but its nearly always the same story - they learn very little new about the way we used to live (as its pretty much documented anyway) but it always but always highlights the changes in modern building practises and our knowledge of corrosion.
50 years ago they probably believed that simply wrapping something in canvas and plastic and applying liberal amounts of grease would be enough to protect it inside a concrete sarcophagus; what they didn't know back then was that water will seep through concrete within days of it being covered unless its protected by a waterproof membrane. Concrete foundations were only protected from water ingress from the mid sixties onwards.
Its why swimming pools are always painted or tiled.
Oddly enough, and this is worthy of one of FB's news items
, the Romans created a stronger, more durable and waterprooof concrete 2000 years ago by hand than we are able to produce now with all the technology we have at our disposal.
