Running Cable Inside to Outside Under Damp Proof Membrane Layer

I don't do double posting normally of course but I have also posted this in building as I'm not sure where it sits.

Can I drill through the wall to the outside underneath the damp proof membrane to run a cable ?

It will be about 6 inches below the actual membrane layer so not damaging the membrane itself. It will also be about 6 inches off the patio surface as well. I have quite a high black brick as you can see before the membrane layer. Not sure if this location for the hole is allowed or will compromise the integrity of the damp proofing. It will be a vey small hole, around 10mm

 

This is double posting - perhaps stick with your post in the Building forum.

 

Yes, I wasn't sure as its a cable that a sparks would be more likely to see this

 

Before I even read this I thought "that's a building question". That it's a cable is irrelevant - it could just as well be a water, gas or oil supply pipe, a waste pipe, a ventilation duct....

 

That it's a cable is irrelevant to the specific question, provided that the cable you intend to run through the hole is suitable for that purpose.

 

Indeed. In fact, even if the cable were not suitable for the purpose, it would still be irrelevant to the question asked!

Kind Regards, John

 

Well... I stand corrected

 

OK - let the builders deal with the DPM issue.

topgazza - what sort of cable is it? What's it for? What size is it? How long is it? What size is the load? What is the protective device? Where will it run once it gets outside? If it's a new circuit have you applied for Building Regulations approval, and what are you going to do about the testing which should be done before and after energising it before it's put into service?

 

Network cable.... so none of the above.

All I was worried about was affecting the DP side of things which I gather I'm not. So many thanks guys.All sorted

 

Drill through into the house with an upward slope, seal the cable in with silicone. If e cable it to run up the wall loop it down into a u bend shape first to stop water tracking down it and into the hole

 

Like the tip with the loop, thank you.
