Hello everyone,
on a house site I have the problem that a 100 mm KG2000 pipe (wastewater) and a 100 mm drainage pipe have to be laid in a narrow corridor of about 50 cm at approximately the same height to the wastewater shaft. Unfortunately, I can no longer vary the heights because with the slope of 1-2% it is already very tight.
How would one proceed with such a laying? The KG pipe is to be embedded in sand (e.g. red cable sand), the drainage pipe, on the other hand, in gravel (16-22). If you do this side by side, there is a high risk that the sand will be washed away. According to my construction contractor, you can also use gravel for the KG pipe, or integrate it into the filter layer as well. 5-12 mm crushed stone is even better (which I don't really understand).
Do you have a laying recommendation to lay the drainage and KG pipe close to each other? About 50-60 cm above that, there will be KG pipes again (e.g. for garage and rainwater). For this, the lower area must be well compacted again so that there are no settlements of the KG pipe nearby, or a further intermediate layer to prevent the washing away of the sand bed.
Best regards
