The Brew Cabin

I'm laying an edging course to accommodate a pattern of Brett Alpha paving. The pattern is such that if I lay the edging accurately spaced (almost to the mm) I'll be able to fit the pattern without cutting very many blocks. Obviously if the edgings wander by more than a few mm over the 1.1m width of the pathway the pattern will no longer be tight - any tips would be appreciated as this is my first project.

Also, the Brett laying instructions recommend spacing the blocks with a 2-5mm gap. Is this over and above the spcing lugs that have been incorporated into the blocks?

Many thanks in anticipation.

If you establish a section of path that accommodates the edgings to both side, plus the body paving, that should give you a width to work to for the entire length which is more accurate than calculating the width mathematically. You will find that some sections are tighter to fit while others are looser, but that's the nature of block paving - overall, you should be able to maintain a constant width.

The recommendation for a 2-5mm joint is standard to all flexible pavement blocks, and most, if not all, manufacturrs now incorporate spacer lugs on the sides of their blocks, so the 2-5mm joint includes the spacer lugs and is not an additional spacing requirement.
