The site supervisor tried to explain a 'zipper effect' that would ensue if we insisted on evening up this difference, e.g. 225mm on one side and 230mm on the other side. Can anybody explain to me what this 'zipper effect' might be? Perhaps the problem is more to do with being unable to cut less than 15mm off the edge of a brick - does anybody know what the minimum amount you can cut off a brick might be? Thanks for any enlightenment on this one... Re: Bricks: minimum brick cut and zipper effect? 2Oct 20, 2010 6:18 am I do not think I understand your question fully. However bricks are placed in such way to prevent straight mortar lines so interlocking provides stronger joints the edge and how much is left or to the right is irrelevant unless of course bricks protrude from either side. Re: Bricks: minimum brick cut and zipper effect? 3Oct 21, 2010 1:10 pm Just to answer my previous post, I've spoken to the construction manager again and: 1) There is no minimum cut size on a brick, they can be cut to any size 2) The 'zipper' effect in this case refers to the perpendicular mortar joints in neighbouring courses moving closer to each other when bricks are less than the standard size. That is, bricks are set up so the long side of the brick is equal to the short side + a 10mm mortar joint. If you start using shorter bricks, you risk bringing the perp joints closer to each other in neighbouring courses, forming a 'zipper' in the worst case.
