16 Mr Wallace made the following observations (quoted from the report):
- Tree roots extend under the fence and continue around both sides of the dwelling
- Tree roots have caused damage to drainage pipes against the side of the dwelling
- Tree roots have caused damage to the concrete paving at the rear left hand side corner of the dwelling and to the cement rendered brick garden edges adjacent to the dwelling
- Tree roots have caused damage to the plumbing water pipes leading to the ground floor bathroom. As a result the connections to the pipes to the shower recess have leaked and had to be replaced. It was necessary to remove some of the wall tiles to carry out this work.
17 Mr Wallace goes on to recommend checking the drainage mains and pipes with a camera, terminating the tree roots close to the fence, excavation of a 1.5 m deep trench parallel to the rear fence to be filled with concrete to form a root barrier, replacement of broken pipes, removal and replacement of concrete paving and garden edges, and replacement of wall tiles.
