Dot & Dab Shelf Fixing

[Ray1000]

I've only ever used normal rawl plugs for fastening any thing to walls but on this occasion at my son's more modern house it would entail identifying the gas pipe and cable locations then using maybe 2" screws into the breeze block which seems over the top for 4 shelves that will only have small light items on them.

I'm wondering what modern fixing versions might do it?

Mastic - Mastic and a pin or two - Double sided tape .....

Thanks

Thermalite blocks?
I never drilled them, I just pushed a screwdriver in the blocks easy to create a hole for red plug.
Less chance or even no chance of damaging something like pipes.

Could use polymer like stixall and 2 screw and plugs. Double sided tape glue dries out and will fall off.
Proper dot and dab screws are

Thank you I’ll study that later …

Corrafix only good for masonry, if you have thermalite requires correct fixings.

Corefix are rated to 73kg in Lightweight Thermalite cf 100 kg in Masonry blockwork according to the maker's website https://metexonline.com/news/diy-sos-how-the-versatility-of-corefix-can-come-to-your-rescue/

Corrafix seems to be a brand of cyanoacrylate adhesive.

It should be straightforward to identify pipe and cable routes.

If you drill into a dab then any suitable plug works. If you are only in the plasterboard it's choose a suitable plasterboard plug. Or go longer and into the blocks with 50mm plugs and suitably longer screws... The cost difference will be minimal and provide a far superior fixing.

I've used Fischer universal UX6 and UX8s to fit items to dot dab and stud partition walls... Their Duopower plugs also look interesting and do a similar thing.

My garage has plasterboard over timber battens on thermolite. I used Corefix for the shelving in my garage, in part because I didn't want a fitting that would pull the plasterboard in towards the thermolite. Of the 20 corefix fittings I used, only 1 or 2 did not make a secure fixing. They may have been at the edge of a block. The other 18 worked well. And, yes, I checked their suitability in thermolite blocks first.

Thank you for the replies I’ll study them and get back to you …

I looks as though I'll have to do the job properly then

I think I was hoping for something dead easy, rather than starting over again with the cable sensor and drilling thro into the blocks.

The TV cabinet and back board were made from scratch and there's only fours screws holding it back to the wall ... there'll be more drilling fitting four tiny shelves!

I didn't know about Corefix so thank you for that.

Presumably what I'm referring to as "breeze blocks" as in our 1964 bungalow will be called something different in a 1998 Beazer Homes house ?

Pity the white plastic plugs are not confined to the board thickness to save concern about pipes and cables
