Hi. Not sure if anyone can help but I just have a few questions. We put a brick paver patio in about 2 summers ago. We live in Upstate NY which means a major spring flooding every year after all our snow melts. When this happens, our patio is flooded for about 2 weeks under water till the water disperses elsewhere. How much damage is this causing over the years and what can I do about it? Of course, money is always an issue...because I don't have much, so putting in a drainage system in the backyard is not going to happen. Will I have to add sand every year between the brick?
