We have these hideous pavers in a large section of our yard. Photo doesn't show it well but they are not flush to the ground at all and they almost go in a dome shape. What options are there for making this flatter? We want it so my son can practice basketball ...due to the angles the pavers are at it's impossible currently. Even having chairs out there is not possible as they are so unstable. We want to avoid having to get a whole concrete slab if possible. Could we do spray concrete or resurfacing if we were able to get a flat layer over the top? It's such a huge waste of space in its current form!
