pinning cable until plastered

[bernardgreen]

I am having difficulty pinning cables into the chasings prior to the chases being filled and plastered over. Some experienced advice is needed.

Most of the chases are in very old bricks and some of which are very soft and crumbly and the pins simply fall out. One wall is hard stone and pins will not go in.

Had the same problem on a job recently.
I used the cable clips but took out the nails, replaced them with 25mm screws and used rawplugs.

As holmslaw said, conduit can be your friend. Unless you've used a twin-wheel chasing tool then you can pretty much guarantee that somewhere there'll be slight bends, little nibs of brick etc sticking out that all conspire to wedge the conduit in place.

Have you thought about using Pinkgrip or similar?

I had but had concerns about solvents affecting PVC but a call to Pinkgrip technical suggests it might be the answer. Thanks for the suggestion.

Most polyurethane foams and adhesives (but obviously not polystyrene ones) also claim to be PVC-cable-friendly. I've often used them to 'tack' cables into place. A bit of mechnaical assistance (often just masking tape) is needed to prevent the expanding foam from moving the cable from where one wants it.

Kind Regards, John.

Most grab adhesives should be safe with PVC. Solvent free ones certainly shouldn't be an issue.

Try a few solvent based ones on some spare bits of cable and see if it does any damage.
