We are sealing the pipe passage. 4 cases, 4 possible situations: ⏱️ 0:00 Water is pouring ???? ⏱️ 0:27 Planning / formwork of an opening for a future pipe ????️ ⏱️ 3:32 The structure will be poured, and the pipe is already there ⏱️ 4:33 There is no opening in the structure yet (don't hammer!, drill! ????) ⏱️ 5:58 The pipe is already in the hole and it's leaking ⏱️ 7:47 Sealing a sewer pipe (mortar facet) ???? Case description 1️⃣ The structure will be poured, formwork with the planned leaving an opening for the pipe - round formwork, rectangular formwork ????. The size of the hole in relation to the actually installed pipe and the shape of the hole left are important. 2️⃣ The structure will be poured and the pipe is already seated around the reinforcement. Installing the Pentaflex sealant on the pipe so that it is concreted and sealed. This applies to concrete, not lean concrete. H-BAU Pentaflex tape 38 mm, 10 m roll. 3️⃣ The pipe is not in the structure (e.g. wall, slab) (but the wall is already there). In such a situation, we drill with a drill and a diamond crown ???? a hole of such a diameter that we can install on the pipe (of known diameter at the time of drilling) a rubber clamping tight transition suitable for the diameter of the pipe and the hole in the wall. We do not punch the hole ❌ because the punched hole does not allow for system sealing. Apart from that, let's respect our health. The hole punched? And now the questions about how to seal it? Such an ugly saying "poverty has shit itself and is leaking" comes to mind... 4️⃣ The pipe is already in the hole in the structure (e.g. wall) and is leaking. With an installed pipe it is different in that you have to be careful not to damage it. Although this is not the only problem, because: ❓ It is also not known what the space is between the pipe and the hole in the wall. ❓ It is not known whether the hole was left (boarded), drilled or chiseled. ❓ It is not known whether the pipe is mounted in the middle of the hole (centrically), although this is important for round holes, because for rectangular ones it is bad anyway. ❓ It is not known whether some type of insulation was used on the outside. ❓ And sometimes it is not known whether someone has already tried to seal it, but failed, because it was supposed to be quick and cheap, so there was not enough time and money to seal it. ????️ And sometimes you know that "it was fixed", because there are packers, foam, and a leak. And it's only surprising that the manager or owner, instead of filing a complaint, again looks for a contractor who will fix it, and in addition just as cheaply as before because the money has already been spent on it, so now there is not much of it. 5️⃣ Sealing the sewage pipe (mortar cove), we do not use mounting foam, clean the space in the hole, make a cove, sand the pipe with paper, degrease it before applying 2 layers of insulating mass to make vertical insulation. What kind? On this object ???? we used: ➡️ 2-component mineral slurry, i.e. elastic (KÖSTER NB Elastik szare) ➡️ you can also use a reactive mass (KÖSTER 2K NB4000) ➡️ or even KMB 2K masses (KÖSTER Deuxan 2K) All available in the Inblock store :) https://inblock.com.pl/sklep/ Links to products from the film: Article about insulation of tight passages: ???? https://inblock.com.pl/uszczelnianie-...
