Split Pergola posts and Post protector wrap

[Blokky27]

I’ve put up my pergola posts and down one side they are in what will be the lawn, set in concrete (postcrete specifically). I’ve bought some post protector wraps to go round the part of the post that will be in soil to protect from rot, but some of the posts have split since I set them, one specifically with a big split down near the base.

I think I’m over the trauma of the actual split to the posts, which I guess is just one of those things, but this one I’m worried about wrapping the bottom of the post, rainwater getting into the crack and because of the wrap, the water having nowhere to go and making the potential for rot even worse.

What kind of timber is that dare we ask?

Pressure treated 100mm square

This should be the right timber to use? Or have I done something wrong?

I was thinking of filling the crack with clear silicone to stop it filling with rain water, or possibly a colour matched one as the clear one would go cloudy in time…?

its fine do not fill it and allow it to drain
if your not happy with the post find another without movement or rotate the split out off sight
timber like that has no loss off strength across the timber and perhaps 5% along the length well within the 20 to 40% redundancy with timber in general

if they are concreted in like i now think they are by reading again ----again do not fill --do nothing ---and enjoy and iff in about 7 years it needs attention then take it from there

I can’t do much about it now - the whole thing is built including all the top joists and its concreted in.

as my correction above says dont worry it will be fine just dont fill the cracks to allow the wood to breath
