Sealing the base of a garden shed.
 

Always a mine of useful information, I thought I'd ask the group if anyone
has successfully sealed of a garden shed to a concrete base.

I have an 8'x12' heavy duty shed being delivered/erected this week. There
is no floor to the shed, which will stand on a large level, concrete base.
I have a roll of 10" wide damp-course vinyl and thought I would stand the
upright walls onto this, then find a way of sealing the vinyl to the shed
and concrete.

I first thought of folding the vinyl up against the shed wall,
stapling/sealing. But then one single leak would provide a well of water in
which my shed could happily rot. So instead I thought I would cut the
vinyl flush with the shed walls, making a neat waterproof seal directly
beneath the entire shed wall, then apply some kind of sealant to the join,
sealing the shed/vinyl and concrete in one go. Does anyone have any ideas
which product would be best for the job? Tar I suspect, would be great -
but I'm no specialist and whatever I use would need to come from B&Q or
Homebase (that defines me as UK-based, for non UK readers...).

Any views appreciated.

Ideally the concrete base should be about 1" smaller than the shed's
dimensions, so that the shed frame sits on the base but the wood
panelling very slightly overhangs it. Rain can't accumulate on the base
and you don't need any DPC or sealant.

You also need to bolt a floorless shed onto the concrete base.
