DRILLING INTO INTERNAL WALLS MADE OF CONCRETE BLOCKS

csouth40 · 21 Mar 2009

Hi

We're trying to put up a new wall mounted coat rack after the last one fell off the wall (leaving gaping holes).

The problem is the internal wall (party wall with neighbour) is made of concrete blocks and its crumbling everytime we drill and put in wall plugs -even using the expanding wall bolts is no use at all. The house is 1930's build we think.

Any tips as to either a) strengthen the wall enough to fix the coat rack? b)any other bright ideas????

Help appreciated as coats have all been living on the settee for a while

Cheers

buy a coat stand?

Have you tried the new (ish) wall screws? no plug needed just drill and screw. I believe they take some shifting.

Use a resin/chemical anchor
or
Fischer Wet n Fix (Screwfix 77888)
or
Use a hammerfix of similar frame fixing

And then apply some gripfill to the back of the rail - if the plaster is sound!

Or, if the holes are deep and wide, then you may be able to fill these with car body filler and then drill and plug this

Cheers for the advice! considering the coat stand idea as the fall back position! lol

How long screws are you using? I've had crumbly walls before and just used longer screws. Wack in a couple of brown plugs in and its sound.

A lot of 1930's properties had clinker type blocks at skirting, dado and picture rail heights for fixings.As you've found out a hammer drill destroys them, Woody's correct a chemical/resin anchor will do the job for plugging and fixing. If it's a party wall use 10" frame screws and charge your neighbours for supplying coat hangers

Thanks for that- tried the long screw/brown plugs- even longer screws and hinged plugs- no use at all- just even bigger holes!

Will try out the chemical/resin anchor this weekend...fingers crossed!

Cheers
