In the summer of 2011 we hired a contractor (very well researched) to build a retaining wall in our back yard. It extends from the foundation of our house to approx. 18 ft. in length and is no more than 4 ft high. It is not straight...kind of curves out a bit after about 4 or so feet from the foundation of the house. Our intention was to build a deck on the upper level of which the wall retains and have a hot tub as the main feature. After the wall was built we decided against the deck and went with a paver patio. Same contractor built this as well.
It came out beautiful...we absolutely loved it. First winter with a hot tub was great. Summer of 2012 with patio was awesome.
A few days ago, after our big blizzard of 2013, we noticed the wall has moved over an inch away from the patio floor near where the hot tub it's starting to lean out. Some of the patio pavers are tilting up...almost like frost heaving but it looks like the hot tub is sinking and pushing the pavers upward.
We called our contractor who tells us we may have to tear a good portion of the wall out and remove the patio to install geo-grid.
We are looking at a very costly repair and I just cannot accept that this is the solution to the problem yet. Has anyone ever experienced this? The height that this wall retains is less than 4 feet. The displacement of the weight of the hot tub should not be affecting the wall like this. I am baffled.
