Gördie21117 Feb 2025 16:24Hello,
we are about to assemble our freestanding pergola from Pergolux and are facing the following issue:
Four concrete footings were poured for the pergola, which are supposed to be hidden beneath the (yet to be laid) patio slabs.
Originally, we planned to screw the post base plates onto the patio slabs, using anchor bolts that would be anchored about 16cm (6 inches) deep in the footing through the slabs.
However, tightening the bolts would likely apply high pressure on the patio slabs (porcelain/stone composite slabs, 4cm (1.5 inches) thick), and they might crack or break.
My question: Has anyone had experience mounting aluminum posts on adjustable post bases that are anchored in the footing?
These are usually meant for wooden posts. How did you solve this?
Best regards, G.

- The posts have outlets for rainwater at the bottom. These would be covered by the panels or the drainage mortar underneath, preventing the rainwater from draining properly (the concrete foundation is 50cm x 50cm (20 inches x 20 inches) in size).
- On one side, we have a vertical sunshade blind. Its guide rail would have to be shortened, and the blind could not lock into the lowest position.

Hello @Gördie211!
I am facing the same challenge.
I’m afraid of damaging the terrace slabs. An alternative would be to try and, if one breaks, replace it and cut around the post.
How did you solve it?
I would be very grateful for a quick tip!
