Lime plaster conduit protection

[tvrulesme]

I've read many threads (some true, some not) about cement corroding copper, MDPE, cables sleeving etc.

Could anyone tell me if lime plaster reacts with anything or if it's safe to bury things directly? Trying to work out what can be put in the walls unprotected and what will need conduit etc.

Any experts, same question with limecrete (NHL 5) please.


Probably one for my go to expert @limeplastering

Hi mate we always advise cables to put in the upvc oval conduit ( the tube like one )
And fix with stainless steel banding and stainless steel screws.
Plastic and stainless steel is fine with lime so would try to avoid any thing else.
If you are going for ufh always suggest trying to fit the manifold on a internal facing wall if possible as less likely for corrosion

Sorry @limeplastering just checking MDPE (mains water pipe. Does that need to be protected as well?

Really informative.

That should be fine but you could go overboard and insulate with the foam lagging more so helps with condensation
