Anybody have experience using expanding polyurethane foam to fill large voids below an in-ground pool?
I suspect there are some sizable voids in the earth below my 40 year old gunite pool which is perched above the edge of a steep slop where there was some grading during construction, There had clearly been some settling over the years by the time I bought the place; I have been thinking (hoping) it had finally stabilized, but apparently not. Two years ago a hairline crack started in the bottom and it has grown to several feet long. It has leaked and i've had it patched with pool putty a few times, which helps for a while.
Anybody know anyone in the east Tennessee area who could (1) advise whether injecting foam might help, and (2) do the injection?
thanks
