Default How to prop up floor joists

Under the house the gap between the earth to underside of each joist
is about 50cm. This is too big for a car scissor jack - I had
imagined using a row of scissor jacks. It's too small for an ACROW
prop.


You want trench props. http://www.toptower.co.uk/builders_props.htm was
the first source thrown up by Google but there may be cheaper options.
As you only want to use them the once, a hire shop might sell some used
ones.
