So, we started filling (1/2 way) last Monday, Tuesday, they finished plumbing and were started back filling dirt behind walls and we were supposed to finish filling w/ water as soon as they were done. Storm came up as they were finishing the backfill and had 2 in of rain in about hour. Dirt and water rushed in under the steps and deposited piles of dirt under liner. The water and dirt caused the vermicullite to crack. Pool builder looked at it the next day and said he saw the problems and would fix it but the ground needed to dry out first. PB is on vacation this week so he sent two of his guys. We had to drain what water we had put in, and when the pulled the liner back it was worse than thought. Water washed dirt around side and down to the slope going down to the deep end. They called PB and he said not to undo liner at stairs (where alot of the dirt is). PB said he would be here Monday morning to fix it.
My question is what will he need to do to fix it? Will the liner be ok b/c I'm pretty sure he is going to have to remove where it is attached at the stairs, and light? He'll probably have to redo the vermiculite too. Anything else? It looks like the rain helped settle the backfill.
