Just a possible future project at the moment...

I'm considering both improving the flatness and increasing the floor
level of my garage by screeding it. It is a little uneven due to the
fact that I very slightly underestimated the quantity of concrete
needed, when I originally laid it many years ago - which left it a
little rough finished at one end.

It could also do with the original floor level to be increased by about
1/2", to improve its resistance to flooding. The later due to a clay
sub soil holding water in extremely heavy periods of rainfall. There
was just a slight ingress a few weeks ago, which I would like to
resolve.

The floor area is 24' x 12'. I have seen screeding laid on top of
concrete to produce a good smooth finish, but how thin could this be
laid? How do you make a screed mix? Once dry, would it be waterproof on
might it allow moisture to track through it?

Any other ideas what to use instead? The finish will have to be fairly
rugged, able to cope with the weight of cars and their
maintenance/repairs.

Thanks for any replies.
