Joint/Seal between wood and Riven Pavers

[Crewood]

I recently built a small wooden bird hide for use on my back garden. I mounted the hide on top of a pation built from riven pavers.

As I didn't allow for the uneveness of the riven pavers, rainwater gets under the gaps between the wooden framework and the riven pavers.

Can anyone please advise what I could use the plug the gaps and stop the rainwater getting into the hide? The biggest gap is roughly 15mm.

Any help or advice would be most appreciated.

What sort of wood did you use?

Thanks for the reply.

The framework was made from treated softwood with treated cladding on the outside.

Any chance of a photo? It’s not too clear to me but I guess the hide has no floor, so when you’re spying on the neighbours, ahem the birds and its peeing it down you have rainwater washing across the floor where you’re sat on a chair presumably? Trying to seal around the perimeter sounds ambitious. Something like a neoprene foam seal might do it but that won’t be cheap for 15mm thick stuff and if the gap varies from 0-15mm I doubt you’ll find any effective seal that will give that much and provide any kind of seal especially just using gravity to seal it.

Probably easier to just add a little raised timber floor of either ply or sterling board inside sat on say 38m battens. At least it would be free of running water if not dry.

Thanks for the help.
