Perhaps the concrete is basically sound, but has a few hairline cracks. In that case you can lay porcelain or stone tiles over the top, to give an elegant finish to your patio. It's a good idea to use tiles with a textured finish, to reduce the risk of slipping when the tiles are wet. You can use other materials such as sandstone, limestone, granite or slate, as long as they are properly sealed. If you often have freezing conditions over winter, then ensure the tiles don't absorb high levels of water, or they might crack. Be aware, too, that existing cracks in the concrete may expand and cause the tiles on top to crack as well.
Finally, after laying out a 1 inch conduit pipe on both edges, fill the area with paver base and by means of the pipes as a guide begin the screeding (or leveling) process using a long board. The conduits will later be removed and the trenches left behind filled in with sand.
So, what is the solution? 1.The contractor can assume there will be waste on the job and only use the best shaped pieces, ordering extra. This should be figured into the costs. 2.The pieces of bluestone can be saw cut to make them perfectly straight, also an extra cost due to the time involved. 3.Let your contractor know you are aware of this problem and that you expect a good job regarding this situation.
