Andy_B Posted July 6, 2008 Report Share Posted July 6, 2008 Has anybody mounted safe to a thermalite block wall ?? if so what fixings did you use...we have tried chemical anchors but think the porus block absorbed some of the resin and hence did not give an adequate fix...there must be a certain type of chemical on the market for this application...if anybody knows what it is...and if it can be purchase from screwfix...please enlighten me....before the wall ends out looking like swiss cheese !!! cheers Quote Link to comment Share on other sites More sharing options...
tinbum71 Posted July 6, 2008 Report Share Posted July 6, 2008 You're always gonna struggle to fix to aerated block as it has such a low nm crush rating. Your best bet would be screw-in anchors (sometimes called thunderbolts) or oversized hole with chemical injection anchor with perforated sleeve. Any expansion type mechanical anchor will just trash the surrounding block and result in v poor pull out results. That said, if it was me I'd drill through and bolt to a plate on the other side. Not all that daunting or complicated, just be aware if you try and pull the safe off the wall, the whole thing'll come down! Quote Link to comment Share on other sites More sharing options...
webber Posted July 6, 2008 Report Share Posted July 6, 2008 Chemical anchor bolts should do the job. webber Quote Link to comment Share on other sites More sharing options...

We ended up bolting the cabinet to the concrete floor in his stair cupboard while the FO waited there are some bolts that you push the housing through the drilled block and they open up like a star in the cavity,heating engineers use them for mounting combi boilers,but we couldnt find them and went for the floor option.

Andy_B Posted July 6, 2008 Author Report Share Posted July 6, 2008 thanks ...should have said ...we have been down the expansion route ...and realised...this aint working.....and also the multi mole with a pre drilled pilot hole...that failed too ....the plate on the other side of the wall will not happen... very new dream house....wife would go benny bongo !!!!

webber Posted July 6, 2008 Report Share Posted July 6, 2008 Drill the holes, follow the chemical anchor instructions, job done. The bond will be stronger than the block. webber Quote Link to comment Share on other sites More sharing options...
2shots Posted July 6, 2008 Report Share Posted July 6, 2008 Forgot to mention,one of the lads drilled into the brick behind the thermalite, and replaced the shorter bolts with longer threaded bar,it worked for him Quote Link to comment Share on other sites More sharing options...
Andy_B Posted July 6, 2008 Author Report Share Posted July 6, 2008 We did that....i use chemical anchors in work all the time (heavy chemical industry) and have never had one fail yet...that said we are always fixing into concrete floors and walls..so long as the hole is cleaned out well and of correct width and diameter...no probs...the ones we used seem to have possibly soaked into the porus block before setting. all four failed...is it possible that these may have gone off..!!...or were duds ....really cant understand Quote Link to comment Share on other sites More sharing options...
staglioni Posted July 6, 2008 Report Share Posted July 6, 2008 Iwould'nt fix any thing heavier than a coat hook to thermalites if i was you i would find a more solid site even the best fixings won't stop the block from fallin apart. Quote Link to comment Share on other sites More sharing options...
webber Posted July 6, 2008 Report Share Posted July 6, 2008 If the resin was quite old, or failed to mix correctly, oil on the bolt, incorrect hole size, debris in hole. Sounds like you did the job correctly, but something went wrong. webber Quote Link to comment Share on other sites More sharing options...
Andy_B Posted July 6, 2008 Author Report Share Posted July 6, 2008 Cheers for all your help peeps...thinking we will go get fresh chemical anchor cement in the caulking gun format....that way we can inject it, pre mixed, to the bottom of the hole, then set the screwed rods in place...also going to make up a thin pipe attachment for the hoover to ensure all debris from gyproc and thermalite has gone.....if this fails we will admit defeat ...and look for another mounting site Quote Link to comment Share on other sites More sharing options...

Bazooka Joe Posted July 6, 2008 Report Share Posted July 6, 2008 I will be surprised if your FLO passes the cabinet fitted to thermalite block, no matter what you fix it with, the block itself is not suitable, BJ. Quote Link to comment Share on other sites More sharing options...
Andy_B Posted July 6, 2008 Author Report Share Posted July 6, 2008 Do they have access to build materials of houses ?....if not he wont know ...and if he cant pull it off the wall...which by the time we are finished with it he def will not be able to do....cause we will try first 6ft 2" and 15 stone cant shift it doubt he will either....

mickeylove Posted July 6, 2008 Report Share Posted July 6, 2008 If your using chemical anchors do not drill all the way through the block, or when you push in the threaded rod you push all the chemical into the cavity. Quote Link to comment Share on other sites More sharing options...

The aggregate in the capsule is harder than the aerated block and wont allow the mix to form properly. Injection will work better, be sure to discard 1st 2cm of mix, but the wall will always be the weakest link. Oh, and Bosch have a new sds machine with built in dust extraction for just £149 + vat. Perfect fr small snagging and diy jobs. (GBH2-23REA) Can you tell I sell 'em? Can ya? Edited July 6, 2008 by tinbum71 Quote Link to comment Share on other sites More sharing options...

Andy_B Posted July 6, 2008 Author Report Share Posted July 6, 2008 it has to be on top floor....ground floor ideal (concrete slab)....but would be flat floor mounted...which personally i dont favour....second choice is loft...pain in the a$$ when trying to get out early morning shooting ...ladders etc etc...waking up family ...pi$$ing off wife....need i go on !!!...will post how we get on tomorrow....this is only the first cabinet...got another and a safe to mount yet ..... once we sus this then there will be no stopping us...

Mungler Posted July 7, 2008 Report Share Posted July 7, 2008 I used liquid polyester on mine (about a tenner from Wicks and applied in any normal skeleton gun) - set rock hard after 8 minutes and could have stuck an elephant to a ceiling with it. I inserted the polyester resin and then stuck in the bolts (rods) and then when set married up the cabinet, added an F-off washer and nut. The trick is to anchor to the floor as best as you can and then secondary anchor to the surrounding thermalite block walls. I will stick some photos up soon as I am in the process of removing my cabinet as I have a much much much bigger one Tell you what, before you stick your cabinet in make sure you have got the biggest one you can.

BJ. the problem is Bazooka is if you say thermalite isn't suitable then you are saying you can't fix them to 99% of new build homes. Despite your reservations FEO's do have an element of common sense and yes thermalite blocks aren't that strong but they do stop an opportunist thief removing a cabinet. With the likes of Brattonsound ones the average thief would need help to carry it off and its not exactly subtle. I'd advise against drilling through to the outer skin of brick as the bolts will them form a thermal bridge through the house insulation which will mean they are a lot colder than the inside of the house and it will cause condensdation on the bolts and cabinet near them which won't be good for your guns. as said just get the chemical anchor right and you'll be fine Quote Link to comment Share on other sites More sharing options...
stet Posted July 7, 2008 Report Share Posted July 7, 2008 Get m10 threaded bar cut 10" long x4 put 2 nuts at one end and lock. Cut 4 bits of flat bar inch wide x 3" long drill 3 11mm holes in the middle of flat bar use jigsaw to make them one big long hole slide on each bar mark holes and drill 25mm holes slide bar and flat in hole poke bar through with long driver till flat is in cavity and pull tight mount cabinet add flats springs and nuts that should hold it. Hope this helps Quote Link to comment Share on other sites More sharing options...
myzeneye Posted July 7, 2008 Report Share Posted July 7, 2008 (edited) mines in the loft, concrete block wall..... drilled the holes carfully and inserted the conrete anchor type studs ( no chemicals) they worked a treat...... i hear what your saying about the loft though.... i have ladders lights and boards down up there, but the hatch is small and akward.... i asked fao about having it in the garage(which is detached but on the house alarm..... he said he would consider it if i wanted to move it as the house is pretty out the way from the street........ i'll see how it goes, but i feel i may end up moving it in time..... once ive tidied the garage a bit that is !!!
