How to fill holes to re-drill into - heavy item.

[foxhole]

Thanks everyone, I've found this thread really useful — I've created a similar problem for myself when trying to hang a c. 18 KG mirror and now have an oversized hole I need to fill (the wall is red brick with plasterboard in front).

I'm going to try filling the hole with the Anchorset Red 300 that was suggested on the previous page, then push in the rawl plug. Will this work with a plastic rawl plug, or will the Anchorset get inside the plug meaning I then can't get the screw in?

Not a similar problem , red brick is solid , just drill deeper and use long screw.
