Joist shims

Recommended Posts

I am about to fit joists into built in wall hangers.

 

If my brickies have got the levels out is there anything I can use at a shim to jack the joist up a bit to get it level?

 

 I am thinking something like these

You shouldn’t shim but it often happens. If these are not ground floor then packing puts the tops level but makes boarding the underside a real P.I.T.A.

I had to after we kicked Builders off site and took it on myself. I had to get tops level. Used plastic packers and nail through bottom hole to keep em in

I had your problem @Moonshine, in spades. maximum error, in places,  somewhat over 20mm laterally, and a few mm vertically.  I talked to the joist manufacturers , Cheshire Roof Trusses,  Cullens and our SE: sent them all the gory photographic detail. BH advice was also a great help. 

 

Cullens  sent me back detailed drawings of what I could do, talked to me on the phone  very reassuring indeed.  No charge.

Have a laugh about our joists on me  (FOC)

I know this is probably sorted but my bc rejected the brick and slate packers that had been put in as he said the can crumble and we needed to use metal or timber shims.

 

May just be his opinion but what they say goes!
