how 2 sink pergola posts into DG patio without making a mess?

modern_missJuly 23, 2013

Hi, I'm about to create a decomposed granite patio and, in a month, I will be building a pergola to provide shade for the patio. The posts for the pergola need to go inside the patio. Should I dig the post holes for the pergola before I lay the decomposed granite and base rock? OR how do i create the holes after the fact? Thanks!

I would build the pergola first, or at least set all the posts, then put in the path.

By all means, posts before your patio.

For ours, I set concrete footings, built the patio and then the pergola. Bolts were inserted into the (wet) concrete so that stand-off brackets could be anchored and the posts set into them.

Here's a current photo. In the link below if you scroll to the very last photos, you can see the assembly of the pergola. Good luck.

OK - you've convinced me...Sink the posts first...but i'm going for a design where the post needs to be precision cut on top.. and my carpenter can't start the project for another 3 weeks. can I build an open top wooden box and sink that into the hole as a sleeve for the pergola? Then i would fill in the base rock and DG around it...not sure if that would work...here's a photo of the pergola design that i'm trying to replicate. I'm not even sure about the dimensions of the post...

Very attractive.

What is the rush? 3 weeks is nothing. There are several critical placements in your design aside from the height. Let the carpenter dig and build, then install the granite surface - excavate for the fill, no more as annz suggests.

That's my suggestion because if you miscalculate anything, the correction might take even more time and cost $$$'s. I'm a DIY'er and often learn on the project but I never have anyone to blame but myself when I error.
