I screwed up. I'd planned to tunnel under about 3' of concrete to run a drain line to an existing drain hole. It would be for future hookup to a sump pump. The drain is covered by a grate. I knew the sides were concrete but planned to dig the it out some. I discovered last night it the bottom of the hole is concrete also. Also complicating things is I can't just bust up the concrete since my concrete block wall is in place. 15 minutes or so extra work with the jackhammer when I had it and I would not have this problem...
So here are my options:
1. Bust up concrete close to my wall and tunnel under the wall. Pull the drain line to the hole and repour.
2. Bust the side out of the hole and tunnel to the hole. Repour the side of the drain hole
3. (my dad's advice) Get a bigger sump pump than the one I have and if we ever get a rain severe enough, put the pump in the hole with a hose.
Is the convenience of a permanent drain line worth it? I MIGHT use this once a year. I'd still have to add a hose fitting so I could hook up the pump.
