putting cable through wall of timber frame house

fret_wimp2

I want to bring a cable through from the exterior to the inteorior of a modern timber frame house with brick exterior.

Due to membranes, watertightness etc, I dont want to just drill a hole without knowing what if there are any additional steps to follow.

Is there a particular process to doing this?

No special tasks other than making sure you're not going to hit any piping or cabling. Through drilling through brick is a bollocks.

Assuming you want to drill inside out you'll probably end up breaking off a chunk of brick on the outside wherever the drill emerges, it probably won't end up a nice clean hole like you'll have on the inside. It's hard to avoid this.

The hole should slope downward slightly from inside to out.

Probably want an SDS drill and you'll obviously need a long drill bit.

Get one of these yokes to cover the hole on the outside:

Well unless it's an airtight house then it's a whole other job of work

I made two with the ryobi one sds drill and these drill bits. One was 1" as far as I recall, which is greater than the max spec of the drill but worked fine.

One was from inside in v small attic space, one from outside. If inside then a mask is a good idea because there might be lots of dust. The facade was slightly damaged as mentioned above when doing it from inside but a light was going directly over it anyway.

Was planning to bung up the holes with silicone or similar, but changed my mind because it would be problematic to remove the cable later. The covers pictured in the previous post are a better idea if not installing something directly over it.

I would not do it.
TF brick façade is ventilated.
Drilling will perforate the membrane inside the cavity, which can't be fixed.

What's the alternative? I'm in the same boat as OP and would like to add an external socket. Can the membrane be sealed somehow?

I drilled one for an exterior socket, zero problem in 9 years. There was already one drilled to get a tv cable into the sitting room @ 14 years ago also with zero problems.

Forgot I also drilled 2 x4' vents,for the oven and drier with no problems

I would presume using circular contuit and blobbing a large amount of silicone around the circumference and pulling it through till it hits the membrane would seal it out. The brick can have a slightly larger hole to see the seal. Once dry then same with the brick.

These things aren't insurmountable.

Wall wiring grommets.

My holes were actually in the wall of a block-built garage with pebbledash on it, not a timber framed house.
