I've got a badly rotted out wood tiki.

On the bottom, half of the base is totally gone, and is removed about 4-6" up the back, and an additional 4-6 inches is gone boring down into the center of the tiki.

I've got him upside down in a storage room right now, drying out in air conditioning.

It's a really large chunk thats gone, and it can't stand on its bottom anymore.

Filling this thing with good wood filler would be really expensive.

I'm thinking of just pouring concrete in there and then kinda forming my own back/bottom out of concrete.

Has anyone ever tried filling a tiki with concrete before?

Does concrete expand as it dries? (will it cause an issue being poured down into the center)

Will the concrete just seperate from the wood?

I suppose I could also use adhesive expansion foam, but this is going to be the base, and it will need it to be stable and support the tiki's weight - as well as keep it from rotting out further.

I can post some pics later- just wondering what your suggestions would be with the back half of the base having totally rotted out 5-6" up
