Roots blocking a drain
On my side of the boundary line between my property and my neighbour's is a mature (maintained at 4 foot high) griselinia hedge. On the neighbour's side (tight up against the hedge) there is a row of conifer trees, about 10 feet tall and 6 inches diameter at the base. There is a drain line crossing under the boundary at a depth of about 12/18 inches to crown of pipe. The drain is blocked with roots which have penetrated the pipe joints at the boundary line. The neighbour maintains that it is just as likely to be hedge roots as tree roots causing the problem. Opinions please?
