Point foundations Pergolux: from when are they loadable?

Just a question, how did you solve the drainage? With the Pergolux, there is an opening at the bottom of the post.

It runs beneath the panels into the gravel.

Ok, does this also work in heavier rain?

So far, yes… let's see. With others, from whom I got the idea, too.

I wouldn't do that with our clay, you'll get a bathtub and with frost after rain or melting snow it can go wrong. If possible, I would lay a [KG pipe] to the cistern or rainwater drain. It doesn't cost much and can also be done easily by yourself.

Fortunately, we do not have clay soil.

Hi. Does anyone happen to have one with wall mounting and can tell me what diameter the screws for the mounting elements on the wall need to be? The diameters for the screws in the floor would also be interesting, so I can get mounting materials in advance. Unfortunately, the instructions say nothing about this.
