Did you ever use the poly?
it dries like concrete, if it washed out there was likely sand in those joints.
when done correctly it forms a solid surface with the pavers.
Doing so the underlying sand can't wash out.
A lot of guys that do this work are perhaps not that skilled.
If you know what your doing it works great, I've used it.
just my opinion?
