Remember a few weeks ago I was enthralling everyone with my exposition on post-hole shovels? Well, one of the posts I put in has developed several cracks in the side.These are about 3mm wide and roughly 30cm long in one case. A couple of others are not as large. These cracks are on two sides only.
First, why is this happening? And second, do I need to start planning the post's replacement any time soon? Recall that it was put in with Postfix in the end, after trying a weak sand/gravel/cement mix.
Note that the other post (I put two in) shows no sign of cracking, but was from a different supplier. These posts are standard brown, treated
4 inch by 6 feet wooden fence posts.
Finally, would it help to dribble exterior grade wood glue into the cracks?
