hanging shelf on concrete block wall.....

[phatj]

Wall made of concrete blocks grouted together. hanging shelf for big textbooks.... will screwing shelf into grout be stable?

 

[meltdown75]

I wouldn't. Get one of those concrete tapping drill bits and make a hole for your screw right in the block.

edit: choice handle :thumbsup:

Hear hear. I wouldn't trust screws into grout holding up a heavy shelf.

Hammerdrill + anchors + tapcons right into block = win.

What they said.

Use the proper anchor and it will work just fine in the grout.

You don't need a hammerdrill for concrete blocks, they are soft enough to drill with a masonary bit and a regular drill.

 

[hanoverphist]

but the hammer drill is much, much more fun!

 

[FoBoT]

use that thing that shoots them in, like a gun

Yeah, but that's not nearly as fun as a hammerdrill.

gonna need special concrete anchors and drillbits like above.
textbooks are heavy, grout is weak

if its a cinder block wall as u indicated, then there should be parts of the wall where it is filled with concrete every 4 feet (i.e. there will be a thin column of concrete inside the hollow part of the cinder block every 4'). find that strip of concrete and use that

 

[hiromizu]

just tape it to the wall. should be fine.

thanks. just bought some masonry bits. i'm renting the place so I wasn't too keen on putting a whole in the cinder blocks (refilling holes w/ grout would be easy, otoh), but oh well!! who needs a security deposit, right?

Bollocks, Just fill out the hole with some concrete / stucco patch. Do it all the time w/ the commercial units we service.
