This is a garage tinker as opposed to a bike although this whole process (of new garage etc) was intended for the Kawa H1F the status of which is in limbo.
The new garage was letting in damp along its base so the installers returned to apply PVA which would waterproof the concrete (they said). I decided to apply a liquid DPM (damp proof membrane) myself on top of the PVA and then applied 2 coats of a two-part polyurethane paint. I was happy with the results but then I saw these 50cm sq tiles made from recycled plastic, about 12 mm thick, not solid but instead they have a webbed construction underneath. They seem durable but painful to kneel on (that might be an age thing), should be a bit warmer than the concrete.
I was determined not to have anything stored on the floor and it's working so far but the shed has suffered (I hope to deal with that next).
The SV is in an "oxygen tent" with a dehumidifier - my plan to dehumidify the entire garage was soon changed when I saw the power consumption of the unit (it's a dessicant type).
