I've removed the render on my house wall as it was frost damaged. I found some of the red bricks underneath were quite badly damaged also, up to half the brick crumbled away. The construction of my wall is a solid wall scottish bond with 9 inch bricks. I cant find a size match anywhere ( i need them by fri) so was thinking using a standard 65mm x 215mm brick with extra mortar to make up the difference. Can anyone advise me if this is okay or not?
