I am looking for some advise.
After all the paving and renovation in back yard was done (and WE thought we could SIT AND enjoy) we were suddenly faced by a sink hole. Were there used to be a tree.
It was a huge tree, taken down 3 years ago. Stump was then grinded, we flattened the soil and it was paved over. Untill now! the pavers have caved in (thank god nobody got hurt). We now see what looks like tunnels. Also some old bricks that we did not put there, so now we're wondering how did this tree get caved in that bad after barely 3 years already and where are these tunnels coming from? there is no obvious tree rot going on.. Needless to say thta it does need to get filled in or removed in order for us to pave again and be safe. Removing we don't see as an option really because of all the paving and levels (small steps etc.) we have in the back and my DH back (hernia!) Soooooo.....................any ideas.......any body??????
