When I opened it up today, there were a sizable crack (I think at least 6mm wide. see photos) in the cement layer underneath. My questions are: Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ 1. Is this a major concern that require immediate action? I don't really mind the brick paving does not look flat and it is not too much of a tripping hazard but I am a concerned that it may cause instability in the foundation / slab of the house (see photo that the crack extend to the slab) though the slab on the inside have not cracked, I know this because I stripped the carpet 6 months ago. 2. There were tree roots in the cracks (see photo), could it be the reason behind the crack? The neighbour have a number of big trees just behind the white fence. I was thinking of pouring poison into the crack to kill off the root so it will stop causing havoc on my side but not sure if it is a good idea. What is your opinion 3. If you were to fix it, how would you go about doing it? poison the tree root then fill the gap or some other methods? Thanks in advance. Ed Re: Cracked cement layer under brick paving 2May 07, 2016 7:38 am This is just the result of movement, not tree damage. It will not affect the slab as the slab is separate and will have been constructed differently. Paths/patio much thinner and may not have had reo etc. Just chop the small root off, fill the gap with sand/cement and relay the bricks. If the edges of the crack are raised, then you could grind them back if it bothers you. Hope you weren't serious about poisoning the neighbour's trees.
