BMcN Posted October 21, 2019 Share Posted October 21, 2019 https://www.bcprofiles.co.uk/thunderbolt-concrete-fixings-122mm/ I use these for most concrete fixings I do, 5 (or was it 5.5mm) SDS bit down through and then screw them in. Recommend a nice long 300mm SDS bit. Link to comment Share on other sites More sharing options...

Drew1000 Posted October 21, 2019 Author Share Posted October 21, 2019 Hi Thanks for info on concrete fixings. This is for a self build. I was wanting to fix the soleplate down before the kit arrives to save some time on the delivery day. Link to comment Share on other sites More sharing options...
Drew1000 Posted October 21, 2019 Author Share Posted October 21, 2019 Forgot to ask what the recommended distance between fixes was, assume 600mm Link to comment Share on other sites More sharing options...
Bitpipe Posted October 21, 2019 Share Posted October 21, 2019 MBC used something like these https://www.orbitalfasteners.co.uk/products/8mm-x-110-express-anchor-steel-zinc-plated as you just need to hold the timber against the concrete, drill through both and hammer this home - there is no additional fixing and the timber goes where it is supposed to - quite quick way of working. They're pretty sturdy as I saw when one needed to be removed - did not come out of the concrete. 2 Link to comment Share on other sites More sharing options...

Just have someone at the end looking down the length. Link to comment Share on other sites More sharing options...
Nethermoor Posted October 21, 2019 Share Posted October 21, 2019 +1 for the concrete screws, these are the best option you have. Full details here if you need http://www.timco.co.uk/fasteners-fixings/multi-fix/mf-range-screw Express nails are ok, but more light duty, more suited for battening etc. and aren't as easy to remove should you need to reposition. 1 Link to comment Share on other sites More sharing options...
jamieled Posted October 21, 2019 Share Posted October 21, 2019 We had Hilti impact anchors at 600mm (offset) centres. Link to comment Share on other sites More sharing options...
dpmiller Posted October 21, 2019 Share Posted October 21, 2019 our TF Co. used a combination of Express anchors and Hilti nails. Link to comment Share on other sites More sharing options...
Gone West Posted October 22, 2019 Share Posted October 22, 2019 Our TF company used threaded rod fixed into the concrete with resin. Link to comment Share on other sites More sharing options...
Oz07 Posted October 22, 2019 Share Posted October 22, 2019 Surely those thundrrbolts in the link above aren't up to the job of anchoring a sole plate? Link to comment Share on other sites More sharing options...
markc Posted August 14, 2020 Share Posted August 14, 2020 Expanding sleeve anchors as long as you are not getting close to the edge of the blocks, otherwise chemical anchors (threaded rod set into resin) as these bond tightly to the concrete without causing spalling or cracking etc. Link to comment Share on other sites More sharing options...
