Flexible house connections

Hello everyone,

does anyone have information about flexible supply and disposal lines in house construction? If the building settles too much due to insufficient load-bearing capacity of the soil and the allowable settlements are greatly exceeded, the connections to and from the house would have to be designed so flexibly that they can accommodate the deformation, i.e., the settlement, without damage.

Does anyone have a tip?
Many thanks in advance!

Hello,
So, if the building were to settle so much that the allowable settlements were greatly exceeded, the house connections would be the least of the problems. The stability of the building would then be at risk.

The pipes are somewhat flexible; power cables especially, then come gas and water in hose-like plastic pipes. Plastic wastewater pipes can also accommodate slight movements.

Hello,

assuming uniform building settlement, structural damages such as cracks in the masonry do not play a role. These would occur in the case of uneven settlements or tilting.

There is a certain amount of leeway with the pipes. However, I am talking about settlements in the decimeter range. There must surely be systems for pipes that can accommodate such deformation?

Admittedly, my experience is still quite limited. Certainly, a soil can only rarely be attributed sufficient homogeneity so that the settlements are uniform.

The loop you mentioned is then located in the ground. What exactly surrounds it to accommodate the deformations? Or would there not be the possibility of a separate shaft independent of the house, in which the flexible pipes would then lie freely?

If the loop is placed in a gravel bed, the pipe or the loop will be able to deform. The support should be compacted, the gravel around the pipe must not be compacted.

A shaft would also be a good solution, but it might also be affected by settlement movements; I think a loop or a tight bend in a gravel bed is more suitable and also easier to manufacture.

Thank you very much, that already helps me a lot. I wish you a nice weekend.
