I'm building a patio with unilock tumbled pavers. Its 12x14 and the top end will be curved. When it comes to cutting the curve, what is best? 1) use a tile saw and cut before laid down 2) lay the curve long, cut the curve with a cutoff saw, then add the border. If i choose this option, do I compact the pavers and then cut so they're held in place, or cut prior to compacting?
