root barrier

Hi Folks, my neighbour has a Norfolk Island pine (I believe that's the name??) planted near the fence line (about 8 years old, 4 metres high) and the roots have made there way into my yard and are causing havoc. I know it's a little late but what could I use for a root barrier after I remove some of the roots. Is there a special root barrier product?

Local council here used thick black plastic sheeting dug in vertically to a few metres to prevent the fig trees wrecking the new paving and retaining walls. Seems to have worked so far - about 3 years of fast growing tropical figs which probably equals about ten years of NIP down south for root mass. Don't know what the product was but a good nursery ought to be able to steer you in the right direction.

We have used a similar product down near Point Cook, on a nature trip where the main Melb-Geelong oil pipeline was only about 10m away. We were planting Plane Trees as street trees and had to dig the root barrier down about 4 or 5 feet.

It was just a plastic membrane that came in a roll, was about 3-4mm thick
