I was installing new sewage pit in the basement.

Cut concrete, excavated 30" out of 31", all gry and OK.

At 31" hit water vein. Water fill's out 3 - 4" per hour.

Drainage tile is there, but at 6" from floor. Water never raises to
that point.

Sooo,

would 8" of pea gravel, fast setting concrete (+hardner) work?

Thanks.

turned out !
