Damp proof membrane

[sivoodoo]

Hi all,

whats the best way to first fix cables to damp proof membrane on walls?

obviously we cant use cable clips as it would let the moisture penetrate.

Any techniques greatly appreciated. m thinking sticky backed trunking, what does everyone else do?

The walls will be dot and dabbed so I will use dry liner boxs.

Thanks
Simon.

Will there be enough space behind the dot dab wall for dry lining boxes? Might need to be Metal KO boxes

Thanks for the reply, but how would you attach the metal back box to the wall without penetrating the damp proof membrane?

Thanks

Gripfill or no nails.

really?! just glue the box to the membrane, Ill give it a try, thanks.

Is it a plastic sheet type if so you could always use these drill the holes for the boxes then hammer these in to fix them up.

Wow! there not cheap!

you're right there, is it for a basement thats been tanked? I suppose even if you do use those, you would still have to put some sealant in between the box and the wall just to stop potential corrosion.

No its a kitchen, the guys who are doing it where not on site and Im trying to find out if they will "dot n dab" or use stud partitioning. Ill have to call them in the morning?
Im thinking of going with the Gripfill/no nails solution as i dont htink i can gaurantee a good seal with them expensive plugs!

 

[pennywise]

does it go all the way up the wall or just above skirting board height.

 

[sivoodoo]

All the way up, they want four double sockets, 2 at worktop height and two underneath for washing machine/dryer.
Pain in the ---!

ahhh just stick them, then when they dob and dab they can put a load of adhesive around them to stick them solidly

 

[sivoodoo]

Yeah Ill call em tomorrow and have a friendly word!
Cheers.

I've drilled and screwed them before now,the damp proofers just wanted the drilled holes injected with silicone before screwing
Probably text book no no,but real world, its ok to say it shouldn't be penetrated,but reality bites
