I am basically a landscape contractor (retired from road construction) but have built some brick and cobblestone walls, layed mortarless brick patios etc. I have taken on a job of installing a 1200 sq ft brick patio using old brick over a poured slab. The brick are ALL different sizes width, length and thickness. (I can give dimensions if wanted) My first question is what will be the best brick pattern to use to accomodate the varying sizes of brick. They want a basketweave. Second, how do I lay it out. I suppose I will need to make fat mortar joints to make up for the length and width of the brick? I plan on using a grout bag to fill in the joints. Is this advisable. What sand/mortar mix ratio is used in laying brick pavers. ANY help with this will be greatly appreciated.
