My garage is conventionally built of concrete blocks with an asbestos
roof. It suffers from a high amount of damp (not just in the winter!
I'd apppreciate advice on methods of reducing this problem. I can make
a winter project based upon your ideas . In advance, thank you!

The damp could be from below, through the mortar joints, through the
chrysotile roof, from air blowing through bringing moisture in which
condenses on unheated surfaces below the air's dew point - or all the
above.

Reducing damp is a continuum.
Sealing off the draughts (there are expensive foam pieces if the roof
is corrugated and open, plus door seals). Then rubbery-bitumen paint
coating the block walls on the inside to stop moisture tracking in.
Examining if moisture is coming up from below. Basic dessicant
dehumidifier to strip moisture out of the air at low temps, but these
cost money to run. Screwing 25mm polystyrene insulation to the walls,
or better 25mm celotex seconds (seconds meaning dented, off-size,
whatever going cheap) insulation boards.

Jonathon,

Presumably the garage is of single wall construction with no dpc built on a
concrete base with no dpm and the underside if the roof is exposed?

Just to kick off, you will have problems with heavy condensate on the
underside of the roof, rain penetration from through the walls and risind
damp.

Could you be more specific about where the damp is showing?

You can get moisture repellent chemicals to paint on the outside of
the walls or you could clean the exterior up and give it coat of
masonarybitumous paint.
The floor can be painted with the same chemical. It's called
Thompson's ware seal or some such name.
You can drill holes into the blockwork at low level and pour this
stuff in. DPC. Don't go all the way through and slope them so the
stuff doesn't run out.

Thompson's water seal that is. It's a stupid price.
The other thing you could do is screw vertical battens to the exterior
and clad with shiplap or feather edge boards. Fair degree of skill
needed sround doors, corners and windows etc.
