Concrete garage

[mikel]

Got a small job to do, fixing electrical supply and points in a garage. The garage is made from pre-formed concrete panels. I've never worked on these before and am just wondering about the best way to fix the back boxes and the garage consumer unit to the walls. Is it best to try and drill the panels n use plugs and screws or fix some wooden panels to the walls (using something like no nails') and then the back boxes etc to them. Any ideas

5.5mm sds drill and red plugs would be fine.

I think the timber and no-nails might be the best. I've done a couple tike that , drilled the thicker part of the panels but the drill still burst through to the outside. Took a plug OK but not the best way . Also theres a danger of the pre-stressed panel splitting if you did a row of holes. Last one I did was to drill the uprights and fix timber between for PVC conduit.

how thick are the walls? i was thinking they were at least 100mm!

there usually something like 25-35mm

if possible, drill through and bolt the wood aswell as no nails. that way it wont go any where. Im sure 2 or 3 black bolts should effect how it looks on the outside either

ah! i dont think i would risk putting a 5.5 through! timber route sound good.

My Concrete garage at home has steel rods in the thickest part of the walls and they are usually right were you want to put a wall plug !!!! it is almost impossable to miss them...

I have done one of these before, drilled with the smallest of masonry drill then enlarged with m6 drill from both sides gently to stop the bursting of concrete. then used gutter bolts or roofing bolts (

Helps loads, the garage is brand new with that pebble dash on the outside. Was planning on using metal clad with plastic conduit. Think its important that the finished job looks as good as it works

I got through 4 masonry drill bits trying to put 2 shelves up in my mum's garage.

That's because you didn't use a SDS drill..

I wouldn't attempt to drill pre-stressed concrete with anything else!
