fixings

[matt.leung]

just putting an estimate together and trying to find a fixing solution so i can price the materials.

the garage shell is one of those concrete interlocking slab types which are quite thin.

what is the best way of fixing accessories to this type of wall/shell.

i was thinking of yellow plugs and screws, just wanted to see if there are any other options.

It is possible to carefully drill and plug the larger concrete sections. Its also possible to shatter and split some thinner concrete sections if drilling to heavy with your SDS. Depending upon the size and number of accessories to be installed fixing some wooden battens to the concrete then fix your accessories to wood battens or boards can make a neat job.

I've looked at and have done a few jobs in sectional garages,,, from my experience you will invalidate any warranty if you fix anything with plugs and screws.

The best option is to fix some wood between the coach bolts (replacing them with longer ones if necessary) or bond pieces of wood to the garage with "no nails" or something similar

as above. avoid drilling as much as possible

As above I made wooden boards liquid nailed to sections which has held well in my dads garage

If You do drill them you may hit rebar too

i drill through and screwed form outside into timber through the holes / concrete when i mounted a consumer unit and double socket in a concrete garage a few years back,

Try and find an adhesive called CT1 it really is the best adhesive/sealant that I have come across. Not cheap though.

As others have said if you drill into them the warranty may be void. The ones I have done in the past have gripfilled either chipboard or ply between the sections and then fixed accessories to this. I have not done any for a few years though because the company I did them for folded. When I did them I made it a two visit job because you need to allow adhesive to go off. I also wired them in SWA as it was a lot easier than using conduit and singles.

Its possible if you stick to the thick bits , to drill for rawlplugs but have to be careful , bit of a pain TBH . Otherwise as above .

I had one, very old. I found even the thick concrete "frames" had steel reinforcement in them, making at a complete pain. Panel between frame too thin for a decent fixing.

As others have said gripfill type adhesive and ply is the way too go.

I've had good results with "Sticks like sh*t" from screwfix, much better then no more nails in my opinion

 

[gselectrical]

I agree with most of the above. I wouldn't bother drilling into them as you won't get enough depth without coming out the other side, to plug the hole and use a screw. Bit of batten, sticks like sh*it or gripfill. Fix accessories, saddles etc to the batten. You will have to let the adhesive "go off" before you fix to the batten, so more than 1 visit required.
