Wall ties

[Eddie10]

hi, I'm going to build a small extension on the back of may house. The one thing bugging me is tying the 73mm outer to the 215mm inner block?? do you have to cut blocks?, do you use screw in ties? are there any ties specifically for the job. any help and tips would be gratefully received.

What's the 73mm outer?

If you're using the traditional s/s butterfly ties, just bend them a little if the courses don't line up (bend downwards to outer leaf, not upwards).

73 mm high brick! instead of the 65mm metric

they'll be out by 25mm or so. isn't that a lot to bend the wall tie??

That's not really too much because the forces across the wall are not usually that great.
Agree that it can be tricky arranging the courses so that you don't bend the ties too much, though a lot depends on the mortar thickness. The 73mm bricks are generally used when bonding into older walls, and they look better with thinner mortar joints. It should be possible to work out a suitable compromise with the mortar thickness.

It tends to work 6 courses - 5 courses - 6 courses - 5 courses and so on. You are constantly having to measure to get the optimum positioning of the ties. Always measure off the damp and never off the last set of ties.
