It’s best not to run pipes in the workshop through the floor slabs. For pipes going from the second floor to the third floor, it’s probably better not to make holes in the floor slabs to pass them through, right? Because it’s difficult to ensure good waterproofing for floor slabs, there’s a chance of leaks occurring in the future no matter what method is used
No, a cofferdam can be built for the floor slab; then, a drainage layer can be welded in place above the cofferdam at the location of the piping and equipment. For wind and frost protection, insulating material can be added to the gaps around the openings.
Everyone wants to avoid going through floor slabs, but it’s simply too difficult to do that in chemical plants. However, given such phenomena, it is necessary to introduce additional control measures to prevent falling objects and secure pipes, etc
We made many holes in the floor slab; there is no welded flashing – instead, concrete is poured between the sleeves and the floor slab
I don’t know the diameter; if possible, using the current foam adhesive will give the best results. That is, it offers good sealing performance and can also reduce the gaps caused by stress changes in the pipes and floor slabs.
What to do if it’s not possible to use the floor slabs? The pipes have to be routed outside and then back in in order to reach the third floor, which is a waste of energy. To prevent leaks, embedded sleeves can be used, along with pre-made holes; the pipes passing through these should be fitted with waterproof caps
