Which resin for improving rawlplug holes in stone wall?

[mattylad]

HI, I have a house built in 1855 during the great stone shortage when only small stones and horse poo were used instead (well, that's what it seems like lol).
Almost any hole I drill generally goes into really old cement, usually black powdery stuff.

As you can imagine, this makes anchoring anything to the walls very hard unless I'm lucky enough to find a large enough stone block upon which I'll be there for ages trying to drill a hole into it with my SDS drill (newish bit).

I have never used a resin before but ISTR that this squirted in would make the holes more secure.

Advise me please guys, which should I be using?
The ones at Screwfix get very bad reviews.

p.s. at the moment I'm only trying to screw wooden battens to the wall prior to plastering, this has required the use of 100mm screws with long plugs, not all worked and I have used lots of toothpicks lol.

I bought some Rawlplug RKEM in the event thermalite im having to screw into wouldn't work but never needed to use it.

Few reviews on Youtube for it.

Yep I use this one but not just for masonry holes, its also good for any stone or concrete repair. To save on buying the miser spouts I take the two part bag out of the tube and squeeze it out like toothpase and mix like araldite

Cheers but I have realized that I have a tube of sticks like poo now on the shelf behind me.
I'll use that when I find I need to.

Although for future use, what about Gripfill ?is that any good?
