Posted this to the plumbing group as well but wonder if more appropriate here ...
We have a very small guest toilet and decided to install a wall hung toilet. Have purchased a Grohe 1.13 SL frame. Have also removed ceramic tiles from the wall (and some of the plaster) revealing breeze/thermalite blocks. I dont know anything about the load bearing capabilities of breeze blocks (thermalite blocks?) but suffice to say i can push a screwdriver into the surface (though I haven't tried for more than a few mm). Two brackets are supplied to be fitted to the wall with a carriage bolt 65mm long of which 55mm will screw into a 10x50mm rawl plug also supplied. The frame is also fitted to the floor.
What is the most appropriate method of attaching the bolt to the wall.
1) Drill appropriate hole into the block, insert rawl plug and screw in the bolt - will it hold. Just worried the breeze block will crumble,
2) As above, but secure the rawl plug in with resin. If so do I drill a slightly bigger hole
3) Use some sort of metal anchor (and if so, what), with or without resin
3) Some other method
Many thanks
