Hi!
Conclusion on the "water damage" that happened in June 2018. The insurance paid although it took a rather long time.
Now the details. [big grin] [eek] [scared] [big grin] [big grin] [wink]
Overview. Floor, and pedestal.
This is where the water emerged, on the pedestal. L is for orientation in next picture.
This was one of pictures taken with my inspection camera of the hole where the water emerged. And please remember I had no idea what I saw inside the cavity, it looked odd, a mixture of "rotten away" and crystalline build up ...
Fast forward we (Pro and I) did the video inspection of the whole sewer system, pipes ... Result = all pipes A-OK.
But why the hole, and why the water?!
Careful chiseling around the drain/pipe.
Wait, what was that?
...
So what I saw inside the cavity was newspaper mixed with concrete. But why?
...
Actually, when the pedestal was poured the drain needed to be liftet/ extended. Whoever did this, thought it was a good idea to fit the new drain/pipe into the old one by "sealing" it with newspaper (probably to keep the concrete out). But of course this didn't really "merge" when the pedestal was simply poured over the joint.
Over the years, paper not fully encased with concrete rotted away, the paper wicked the water into the concrete and it "rotted" too.
With the heavy rain and a lot of pressure on the pipes, one little piece of concrete finally couldn't take the pressure anymore and bursted out.
I'm happy it wasn't the pipes or anything else, but I would have never thought of something like this.
Kind regards,
Oliver
