As above, I need to build a wall out of breeze-blocks to separate two units . The door way is approx 15ft high and 20ft wide. The floor is concrete and is uneven . I have a few questions
1)do I need to tie it into the Walls at either side?
2) can I build directly ontop of the concrete? (5" deep)
3 what's best way to level it before first course of blocks?
Cheers in advance

1/. Yes, use wall starters
2/. depends on whether the floor is re-inforced and the height of the wall needed
3/. depends on how uneven it is
Ah mis read that, 15ft is still pretty high, you'll need to tie the top too I think

1) structural engineer would tell you to tie it into both walls otherwise it will tip.
2) whats below the 5" deep concrete?
Cheaper building a timber seperating wall?

I'd say 2-3 inch out . Would I lay a level cement base and build off that , below concrete is probably soil, the concrete base has reinforcing bars, the blocks I'd be using would be the ones with two gaps in them as I have a load already . Forgot to say I also need a door way in this wall too. What's best way to tie them to other Walls ? The wall I am building to at the top is steel rsj

As Jules said use a wall starter, a metal rail you fit to the existing walls and you slide wall ties into the rail.
Screwfix sell them

I'd fire a straight edge on it as 2-3" seems a bit vague....and miles away from todays tolerances
2" I'd say you'll be fine just using mortar to level it out
