Hi all. Quick question if I may. I'm looking to put down a shed slab (4 x 2.5) and the area where it has to go has 4 large palms of some description (approx 4-6m high each, and a load of golden canes. If I was to cut these down at ground level, what would happen in the future if I was to lay the slab on top? Would the stumps eventually turn to mush and cause the concrete to sink or crack? I really don't want to go down the road of digging up stumps obviously, but what are my options?
Thanks in advance.
