I would want the trench 10-12 inches deep, depending on frost depth the footing could be much lower.Hello All,
Question, as some of you already know from all my previous questions, I'm in the middle of installing an interior drain system in my basement... I broke up a small hold in the floor so I can get a feel for what I'm in for when digging the trench, and to determine the depth of the footers (Which I still haven't figured out.. lol)
My question though, I dug the hole down last night, just over a foot deep maybe.. I checked it this morning, and it's full of water (maybe 2 inch's from the top)... Should I be concerned? If you remember from my previous posts, I'm the one that recently found a square cement encased hole on the floor (Maybe 2 feet deep), that keeps itself full of water.. I've pumped it out a few times, but it keeps filling...

The deeper you put the trench down the more water you will have to pump.
Was there a gravel layer under the slab?
