I've lived in my house for 3 years and other than the noise from the traffic (my backyard butts up against an expressway with a sound barrier wall) there have been no problems. About two months ago I noticed a lot of vibrations in the house when a big semi would pass by and I recently noticed that when I have a glass of water sitting on my desk, there is constant movement in the water. Now I'm noticing that my wood floor boards are beginning to flex and creak. Also, I'm hearing my walls and floors pop and creak constantly. Needless to say, this is really depressing me as I just recently finished remodeling the entire house. I don't see how I will ever be able to sell this house because any prospective buyers will immediately notice the vibrations from all the trafic. This may or may not be connected but we've had a lot of rain (Chicago) and b4 that a lot of snow melt. My yard has a few low spots along with a downspout that puts a lot of water against the house. (I recently installed a dry well but it's insufficient; I'm think of running a trench the length of my yard and have it drain off my property). Could my property be so water logged that the vibrations from the traffic are causing my house to vibrate? thanks.
