well it was hardly a high tech project;
There is a small lip where the two epoxy/sand pours joined, but it serves to trap water on the sump side, so I just pretend that it was part of the plan.
BTW the sand/epoxy mix is never coming out. I tried to grind a little to level off the sump and lets just say it took a while.
This is what I plan to install as a sump pump;
The Whale Supersub smart 650.
