Fixing to Stramit overhead !

[Soulsurfer]

Hey all, I have a flat rewire for a regular and upon cutting ceiling we have found that old stramit straw covered in cement stuff quite deep before the concrete again, anyone got any advice / ideas on method to attach slip tube to run cables in before skim again ? I can't think of much inspiration at present ! cheers.

Unibond no more nails.....a blob sticks to most things.

did think of trying grip fill or similar but maybe drilling right into concrete and fixing a loop of perforated band / tub strap to hold it too.

It's all ancient black enamel conduit but no cpc's separate just using tube as earthing to old steel board and plug in mcbs just singles to each outlet.

Just beware that there is a straw-type substance with quite a high Asbestos content. Found lots of it in roofspaces in a school near here.

The only time that I have had to deal with stramit was used as internal wall partitions at regular intervals it had holes through for wiring never known it to be used on ceilings though.

some kind of epoxy resin.

Could you not use the existing conduit, or is it being removed for some reason?

why not re-use the existing conduit and add a cpc conductor if the conduit is not goo

one would think that, given the age of the installation, the old conduit would not serve enough points appropriate with today's needs.

Yep going to use the existing conduit and unfortunately can't get another singles cpc down the conduits so going to use conduit plus earth off back of the solid back boxes to accessories too and make sure well low enough.
