How level should a new wall be

[willismp]

Hi,

We are having an extension build, just got upto damp and I noticed the inner leaf is totally level, but the outer brickwork runs out and is 40mm higher at one end, over an 11 meter wall.

Obviously where we have no openings it would be noticable but we have some large sliding doors which will need leveling.

How much out is acceptable?

N.B Builder blamed the foundations, but he managed to get the inner leaf correct, and its 11 brick courses upto damp & 2 blocks.

10mm high on a corner is acceptable as you can grind that down easy enough before ground floor sill height.

You can not blame the foundation as being high. He should have cut the grunter out in the first two courses above founds.

Take it down to three course below ground level, then cut the pig out.

We are building an extension at the mo' and the existing house runs down 35mm from one side to the other. We have no choice (the brick courses have to line through) other than to lose the discrepancy over the whole of our footprint.

Either one, two or all three walls will be out of level at some point. Ho hum.

If it is avoidable however, then there should be no excuses.

Pig
Grunter

What are they in layman's terms?

Not sure if there is a laymans term for a grunter. Have seen a few on site over the years where the storey rod has 1.5 inches at the bottom and one of the trowels has bumped up instead of grinding down like the rest of them.

Nose, we're building one at the moment where we are matching back into an existing extension and there is actually a pig in the wall. 27 courses on one side of the doors and 28 the other!! Wow. I though 'pigs in the wall' were just made up. Blew our mids figuring it out, you just don't expect it.

40mm is not acceptable (neither is a pig), gauge is there for a reason.

A whole course o' pig is a killer! Only seen it once and I was the labourer at the time.

Proper head scratching time!

The first sign is usually when you notice the line is pulling slightly up or down when you are running in.
A mate of mine had 2 on opposite flanks going the opposite way on an extension at Currys. They just got left in and the chippys got over it with the flat roof.

You shouldn't be running at all. You might hurt yourself.

Especially at my time of life.
