Re: ROOTS ruining my foundation
If you can't do anything to the trees or hold your neighbour responsible --- don't know what to say other than roots will migrate to where there is moisture.
That's why many times clay pipes are affected since they easily crack. When they do moisture is readily available underground and the roots will seek it. Once they get into the clay pipes the worse they become.
Unfortunately the only consolation I can offer ---- imagine the issues the neighbour must also have.
