(Signal Mtn., Tennessee)
I have a 19 by 34 foot raised patio (about 2 foot tall back filled with a concrete slab on top) at the back of my house.
It had flagstone covering the slab but the roots of a very large oak tree within 2 feet of it has bowed the slab up visibly over the years and the flagstone had broken and come loose.
I removed the flagstone and when I did that I found that the concrete blocks holding the north wall had crumbled making the slab suspended on the back fill.
I'm now trying to decide whether to
(a) cut down the tree and have the slab leveled (pour a new one on top of the old one) and the wall rebuilt; or
(b) level concrete block supports across it, put posts in the ground on the north side (with the crumbled wall) and build a deck on top.
Budget is very tight since my teaching income is the only income in our family right now while my wife raises our children. Are any of these realistic ideas?
