how to seal cables through concrete
how to seal cables through concrete
(OP)
Hi all
I detected that in some buildings we have power cables coming in through concrete walls, without any sealing.
Now I want to seal them. I am thinking in some kind of resin that we could pour through the opening, sealing after seting.
This resin should have the following properties:
- high penetration, so every space between cables and concrete will be sealed
- fast seting
- flame resistant
- UV resistant
- water resistant
- rats, mouses, insects resistant
Polyurethane is not good enough.
Do you know any product that can meet these (at least some of them) requrements?
Best Regards

Google up: 3M Fire Barrier IC 15WB+ Sealant.
There are others.

I think RTV [GE or Dow Corning or other] Silicon Rubber will be better in your case.
I agree with alehman, you have to check the wall [or floor] fire rating in order to build a suitable fire stops. If it is difficult to know the penetration wall rating- but if it is concrete or bricks made- you may take the maximum-3 or 4 hours. It could be more expensive but it would save the time.
Fire Stops materials shall be tested as per ASTM E 814 by Underwriters Laboratory, FM or other testing and inspecting agency acceptable to authorities having jurisdiction.

Thanks for all inputs.
I will analize the datasheets of each recommended product to make a decision.
I also found the product Sika Firesil, that I think it is equivalent to 3M Fire Barrier.
