Extra distance, post-pillar?

[Fredrik_Tjernberg]

Hi,

I am just about to set up the posts for our newly built carport on pre-ordered concrete piers. The base plates are embedded flush with the pier, see picture. Now the question is: I have seen other new constructions where the posts are not placed directly on such a pier, but a stainless steel spacer is placed in between to prevent the post from resting against the pier. I assume this is to prevent snow and water from being absorbed into the end grain. I have a 90x90 laminated beam that I plan to oil at the end before placing it on the pier.

Are spacers really necessary, or is it "overkill," what do you think? Where can I get such spacers, are they standard items at hardware stores?

Thanks for the help

Put some syllpapp at the bottom, that should be enough.

Exactly. Ordinary tar paper and maybe some cold asphalt will certainly suffice. If it rots after 50 years anyway, you can just cut out the affected part and knock in a new piece.

One good thing about not placing the post in the bottom is that there is an opportunity to adjust the attachment afterwards, if the plinth should rise from the ground or for some other reason.
