Hi, we moved into our house 18 months ago and over this time we are getting increasing vibrations throughout the house when busses and HGV’s pass by. There are two 50ft pine trees in front of the property in our garden, roughly 6 metres from the house and 5 metres from the road. The driveway is lifting and dropping in places and we believe these trees are the cause of these increased vibrations from traffic as they are so big who knows what the root system is doing underground. All drains are fine and we have eliminated all other possible causes. Could two pine trees this size really cause changes in the way earth absorbs traffic vibrations? We are in Essex with clay soil. Any advice appreciated, thanks.
