Hello everyone,
Attached is the current or planned floor structure.
Base slab - 30 cm
Insulation - 20 cm
Sand - 5 cm
RC gravel - 60 cm
Soil
We had to do a pile foundation and on three piles the pile cap is slightly in the way of the wastewater pipes.
My questions:
1. Do the wastewater pipes need to be relocated or can the obstacle be bypassed?
2. If it can be bypassed, how should this be done?
3. How are the protruding pipes actually fixed? I don’t want the pipe to lean slightly in one direction shortly before the floor slab is poured and then the walls no longer fit exactly.
4. It is said that the wastewater pipes should be frost-proof. They said 60-80 cm. Does this also apply to the area under the floor slab/insulation or only to the unbuilt area?
5. I was advised to connect the wastewater pipes to the floor slab with retaining loops, meaning the loops should be cast into the floor slab. Reason: The house will not settle due to the pile foundation. But if the ground settles, there would be no risk of damage because the pipes would then hang on the floor slab via the loops.
6. What happens if a wastewater pipe protruding from the floor slab does not fit 100% into the wall of the house (timber frame construction)? How flexible is that?
7. I want to lay a conduit under the floor slab to the garden area later to have electricity in the garden. How deep should it be buried? Use a standard KG pipe or flexible conduit? Is DN50 sufficient? Or should the conduit rather not be routed under the floor slab but alongside the house?
8. Grounding: The builder recommends a grounding tape that can only be laid a few centimeters into the ground. The earthworker says it should be laid in a ring around the entire house. The builder says a semicircle is sufficient. My problem is, I cannot go all the way around the house because a part of the house stands on supports. Am I allowed to lay it in one area also under the floor slab? If it doesn’t have to be laid in a ring, then the issue is resolved anyway.
Many topics should actually be clarified by the builder or earthworker, but I just can’t let it rest right now and I can’t reach anyone on the weekend. Of course I also need some knowledge to engage in conversations with both.
Regards
Tito
