been advised to post this in gardening - tree roots causing cracks in the floor.

[passionsrunhigh]

been told that if the tree stump gets larger (tree was taken down about 5-10yrs ago) there will be more cracks in the garage floor which can destroy the structure. One large crack made the foor uneven though useable. There are also shrubs around right next to garage so not sure if they are not causing same. Surveyor told me to do the work asap as i need garage for storage so don't want any damp appearing (or to lose the garage eventually!). To me it sounds almost impossible to dig out the roots of the stump, as he seemed to suggest. How much would this cost and who best to do the work? Is it even possible, or the surveyor sugar coating it? The floor is concrete and if needs relaying after the work - what's the cost of that? grateful for advice!

I'm don't know the answer but neighbour had similar issue with roots of a big cedar that cracked garage floor and burst his water pipes. It is all sorted now, but not sure who did it. Probably the tree surgeon who deals with the tree, try a couple of those. Also, I vaguely remember something about the insurance compant so might possibly be worth speaking to them.
