Supporting cast iron down pipes in EWI

[Rigsby]

Got a job to do with 90mm polystyrene. The customer is going to fit cast iron down pipe and intend to fit threaded bar into the wall prior and then bolt the down pipes on tight up to the thin coat acrylic finish.

His concern is as he will have to tighten the nuts up tight he will puncture the acrylic?

Any solutions anyone?

Could he not sleeve the threaded bar ,or silicone when fixed?

patresses and rubber washers at the back of the fixings to prevent water ingress

As paul says, gasket washers in addition to what he suggests should be rigto

They are good suggestions. I will pass them on to the client.

Thanks!

Tell him to get some 5 mm x 50 mm flat galvanised steel bar then, cut to appropriate length and drill the holes to the correct centers then fit nuts to the stud and set the flat bar over the top of the threaded bar. bobs your uncle fanny's your mothers sister you have a nice solid base to fix to oh and tell him to get stainless steel threaded bar if he wants to belt and brace it

Dbp sell rigifix anchors that have been invented for exactly what your doing...check em out. Transfers weight to substrate with no compression of insulation or cold bridging etc.

I have a sample of one of those. I don,t think they make them long enough for 100mm. i will ring them tomorrow.

I have been asking for fixings like this for over a fekin decade i seen fixings on the market this year but seriously how far back are we.

on the other hand clients will have a fit when you start pricing in specialist fix for enabling works hahah

John , as John said threaded bar fixed into the wall with resin bond extending beyond the ewi and allowing for a back nut then through the bracket and fastend back to the other nut that is sat just above the surface ove the finished render so there is no crush effect on the render , if you get my drift, but then i suppose a sleeve over the bar as Johnasif suggested would do the same thing maybe just a little more expensive

There's a lot of Johns on here :RpS_thumbup:

[johniosaif]

Going to the mattresses was an old mafia saying,,maybe thes spreads are "connected" wise guys ?

There are other products on the market, if you don't want to use timber grounds or
threaded rod, there is rigid polystyrene and rigid polyurethane blocks, these do not crush when objects are being screwed to them, plus no cold bridging.
