Hi guys

I've been adding some extra network cables around my house (bundles of 3 cat6 + coax) and as they go under the house have been wondering what would be best to use to seal the holes in the floor i have fed them through?

I used a 22mm spade bit so the gap isn't huge, but i want to pack it with something to stop any possible rising damp issues


Is a product like Selleys Space Invader going to be safe to have in contact with the PVC plastic of these cables?
Or should I just pack some of that foam draught stop tape in the gaps?


What do you think?
