So I just laid a large-ish patio with pavers (with the joins filled with sand) and now we're wanting to build a 12'x12' pergola on the main area.
I know ideally I should have planned the pergola before hand and set the posts first or at least left a few of the pavers out, but alas foresight wasn't one of my strengths here.

So, the question now is how do we anchor the pergola to the patio? We don't want to anchor to the house...so it's just a freestanding, 4 post structure we're going for.

I've read about using steel rods drilled into the pavers/ground as a way to anchor, but wasn't sure if there were any better/easier ways of going about it.

Additional bits of info is that pavers are 3 inches thick plus 1" of sand and 4" of 3/4" crushed mountain granite below those pavers and then just good 'ole dirt below that.

So, any advice/tips on this would be great.

Nice Patio, I'm sure the Pergola will be magnificent. Before sinking big bucks in the Pergola I would consider sinking a DIY foundation.

A proper foundation is always important. In Denver you also have to consider

I would consider Sonotubes as there are ways to conceal the base to make it appear that the Pergola posts are just growing out of the ground.

You can't really put that size structure on a paver patio, too much weight. You need to remove the pavers under the pergola where you pour the sonotubes. The piers will carry the weight of the structure.

The pavers will not be any kind of support to attach the pergola posts to. I would do a proper footing.

It is much easier to pull up a few pavers now and do a proper footing and pave around it now then.....rebuilding your pergola after it falls down AND still having to redo some pavers becuase they pulled up with the post as the pergola fell over (hopefully not landing on anyone or anything).

Just me 2 cents...:whistling2:

what would happen if set on paver?

what would happen if set on paver?
would the weight of the pergola make the pavers sag in that area?

I have about 20" of stone under my patio due to the grading that was there? does that make a difference?

Shpigford,
I am in California and have the same issue. I know this post is some years old but how did the barrels filled with concrete work out for you? Or did you end up anchoring your pergola using another method? Thanks Mark
He hasn't been here for years so you may want to ask a question in a new thread. :wink2:
