quick help - concrete bolts

Recommended Posts

Typical . I have left it to the last minute ! :shock:

The guys are coming tomorrow to lay my concrete slab [ they phoned this afternoon ].. and I just realised that I want to put down some kind of anchors so that I can hold my WIR in place

 

I have seen these:

Do you think they would work ?

 

Too late to order on the internet now ... :anxious:

they will do the job 10mm is a bit on the big side but they will work but I'm not sure if they will if they are set into wet concrete. better used after the concrete has set then drill the holes put the bolts in

this type is better for setting into wet concrete http://www.screwfix.com/prods/15409/Fixings/Thrubolts/Thrubolts-10-x-100mm-Drill-Size-10-Max-Fixture-35-Pack-of-10

but with both you've got to be bang on with your measurments personally I'd wait until the WIR is in place then drill the holes thru the timber/metal stud of the WIR it's a lot less hassle

Emchook - if you are stuck, send us a PM. As part of our business we fix stuff into concrete and brick.

 

We favour chemical resin fixings, as they are much stronger than shield anchors, which rely on having strong concrete that does not crack - often that is not the case, although as you are having new concrete laid, you should be alright. Also you will need to let the concrete cure for 10-14 days before putting anchors into it, unless you use the ones that are set in when you lay the concrete.

 

Give us a shout if you need any more help/advice.
