Altmark19808 Mar 2023 21:33Good evening,
House built in 1980.
Basement with driveway and parking space. Basement is below street level.
A camera inspection of the wastewater pipe (ceramic pipe running diagonally under the house) showed that it has settled. One pipe section was sloping slightly upwards in the direction of flow.
Today, I dug from the outside down to the strip foundation and saw that there is a large cavity between the pipe and the basement floor (15cm thick (6 inches), no foundation).
At some point, the pipes outside were replaced, but the connection to the pipe under the house was not done professionally. (The pipes were just laid end to end without a sealing ring.)
This leak has further contributed to the ground settling.
What do you suggest? Should the cavity be compacted and sealed?
If yes, how?
Have a nice evening

Good evening,
House built in 1980.
Basement with driveway and parking space. Basement is below street level.
A camera inspection was done on the wastewater pipe (stoneware pipe running diagonally under the house) and it was found to have settled. One section of the pipe was slightly inclined upward in the direction of flow.
Today, I dug from outside down to the strip foundation and noticed a large cavity between the pipe and the basement floor (15cm (6 inches) thick, no foundation).
At some point, the pipes outside were replaced, but the connection to the pipe under the house was not properly done. (The pipes were just placed end to end without a sealing ring.)
This leak has further contributed to the ground settling.
What do you recommend? Should the cavity be compacted and sealed?
If yes, how?
Have a nice evening Seriously: Please consult a professional civil engineering or groundwork company to address the issue.

I have no idea what exactly needs to be done, but I think it makes sense to closely monitor the situation and take appropriate action.

Waste pipes must be watertight.
In my opinion, everything needs to be removed and replaced.
These soakaway pipes are prohibited, and you’re lucky that the utility provider hasn’t required you to take action yet. Which soakaway pipes do you mean? I don’t quite follow you. The ones shown have no soakaway holes.
If you mean the stoneware pipes, then many homeowners would now have to start removing their front yards and floor slabs.
And if we didn’t care, we wouldn’t be paying attention to it.
