Raw plugs in Old Walls

[olly_baker]

Hi everyone,

Sorry if this is in the wrong section but I didn't know where else to put it.

We have bought an old (1910) house, and am currently trying to fix a bathroom cabinet to the wall.

After drilling the holes to a depth of about 60mm, inserting both medium weight and heavy weight raw plugs and fixing the cabinet using masonry screws the wall simply disintegrates / crumbles, leaving a large hole.

I have filled this hole using Polyfilla, but now don't know what else to do. The wall has a thin layer of plaster, then a large thick layer of what seems to be old plaster / cement which isn't very solid. After drilling in 60mm I haven't reached the brick work.

Is there anything I can use to ensure the fixings remain? I have heard that there is a product available that you inject into the drilled hole which binds the wall surrounding the hole together with the raw plug, forming a firm solid base for the screw. Anyone used this?

Any help would be apprecitaed.

Thanks

Pollyfilla? Are you having a laugh? Try products like these:

Have you seen this ?

I have no idea what it's like, just seen it in the Screwfix catalogue page 41 called Wet'N'Fix

I've seen those things in Wickes about £1.80 for 20. Never tried them though.

You may have gone into a layer of mortar between the bricks. If you move it up or down a bit you may hit brick. Or try big blue rawlplugs.

1910 House.........1910 solution Whittle a piece of wood to the size of t`hole and bash it in with a club hammer, then make pilot hole for screw with a bradawl.that`s what was done before Rawlplugs

Too true Nige, but he's trying to mount a bathroom cabinet - not a 1910 problem

Drill deaper and use longer screws

There is a part mix (not really a mix 2 strips different colours)from rawplug I think. Rub them together pock in the hole sets like S**** holds my curtain pole up & my house is older than yours. B+Q Stock it, where all the plugs etc are

i go with nige on this one, fill hole with a bit of gripfill, then a piece of wood as he says, leave it to go off and jobs a gooden!

(just another thought, its not a lath and plaster wall is it?)

I'm out!

Right - Thermo, it's not a lath and plaster wall.

I've gone out and got some those Wet and Fix strips, and going to try and find some Polyester resin.

I've already drilled in 80mm, and surely do not need to go in any further than that. If all else fails I'll have to though I guess.

Would another option be to stick a baton of wood on the wall with No More Nails, and screw the cabinet on to this and into the wall?

Oh, and thanks for all your help so far.

Soon you will be able to put a plate in your neighbours house if you much deeper

Yeah I know. One of the reasons why I don't really fancy drilling too much further!!

Can you let us know how good they are
