Built the pool/attached spa in 2009. As soon as we filled it with water for first time, water seeped through the grout of the spa. Pool builder has worked on it 3 times. I am waiting for yet another leak detection company to come out (this will be the 3rd time and they have never isolated the leak). I have pics of all phases of construction. One person told me that the reason my spa leaks is that there was no backer board on the front of the spa and when they shot the gunite, the weight from all that concrete caused a leak probably in one of the pipe connections.
Builder came out in 2010 and tore down front rock fascia of spa and raised bond beam rock wall behind pool. There was evidence of a water line throughout. This had to be done because we had 3 days of 20 degree weather and despite my pump running 24/7 the water behind the rock wall froze causing the rock to crumble and fall into the pool when it thawed.
Should there have been backer board in the front of the spa? See attached photos. Thanks! The 2nd pic shows the water seeping through the grout when we first filled the pool/spa.01_0162.jpg01_0506.jpg
