What to seal SWA into brick with?

[skotl]

Hi all

figured this was best in the building section as it involves bricks, rather than electrical! As part of an extension, we had the builders / electricians run Steel Wire Armoured (SWA) electrical cable to the garage.
The SWA enters the house about 12" off the garden level but they just drilled a muckle great hole and stuck the cable through.

I'm perhaps exaggerating; the hole is roughly the diameter of the cable, but it's unfinished on the exterior brickwork.

We have a bunch of snagging to get through, though nothing serious and I was thinking that I would just seal this up myself rather than get them back to do it.

What do you think I should use? Some kind of external silicon seal?

Cheers
Scott

That's what you call DIY, even answer your own questions

You're a gent. And back to you, old chap!

We could keep this mutual appreciation thing going for quite some time, I think....

Indeed we could, but lets not take the urine!
I am sure there will be other occasions in the future, when appreciation can be shown to each other via the thanks button.

You can certainly get silicone fillers in different colours.

An alternative might be the non or slow setting mastics that window/door fitters used to use back in the days when a proper job was the norm.

Whenever my sparky has run SWA cable, he's always run it into a junction box before going down to standard cable internally. The junction boxes are all watertight etc for the connection to be safe.

It's just occurred to me today that these cables normally have some kind of shield over them as they enter the wall, don't they?

Had a quick google but I'm not getting the search term right.

Cheers - it's not a junction box I'm looking for it's "capping" or similar - found an old thread on here where someone else describes it perfectly as;

"like a sturdy plastic semi circle tube with with flat edges and is used to cover cables running up walls" (//www.diynot.com/forums/viewtopic.php?t=189466)


Unfortunately, the item linked to in that page is no longer available so I've got a better description but still don't know exactly what it's called.

Now i'm curious!!!

Do you mean electrical conduit?

Nope. Err yes. Err nope. I don't think so.

I wonder whether it's Sky installers that use what I have in my hazy mind... Imagine a piece of round conduit, cut lengthways so the cross section is an open semi-circle, with flat edges that can be screwed to the wall.

At the top, it's a full circle to cover the cable as it goes into the wall.

Sorry I couldn't be more help! !

Good luck mate.
