Does anyone know much about PTT ?

If you dig a hole, put in some hardcore/gravel and plonk in a PTT ... back
filling with more gravel and compacting ... how will it fair with the
elements?

Basically, is it really necessary to concrete the posts in as they will be
securely held in place by the (above ground structure).


Putting gravel around the post in a hole will help to let the water drain
away from the post and hopefully prolong the life of the post.

If Concrete is necessary the thought of using gravel is probably a moot
point. The concrete tends to hold moisture and can aid in the premature
failure of a post. Having proper drainage away from the post will benefit
and help to prolong the post life.
