The general concensus from most of the people (who mostly claimed to
be brickies, etc). Was don't soak the blocks (as it can lead to
cracking when they dry out), but use a wet mix and get them down
quick (one or two did say they had been on site and seen them being
soaked). But then, they may be more interested in how quick they can
get paid and move onto the next job, rather than the longevity or
otherwise of the structures they build.

What does the team think?

The concrete foam type of light weight block is unlikely to benefit from
soaking. You may need a bit of dampening depending on how hot it is when
laying them, but I can't see it being an issue this time of year.

(all the load is in compression anyway, and the light weight blocks have
little strength in bending, torsion, or tension - so the strength of the
bond is relatively unimportant as long as the mortar was hydrated enough
to allow proper curing)

You can check various technical guides he
