At the other place we had one side that stayed kinda wet and didnt have a way out with a tile, so I drilled some holes as deep as a power post hole digger would go. I only used the 4" auger on it, ---- didnt take long to do the area and did drain after that.
Told another guy on another forum way back in time about it and he said it worked for him too.----just an idea, no promise it would but if all else fails, might be worth a try!
