The kitchen outflow drain is cracked and damaged. The water from the kitchen, once it has exited the house and gone into the drain, is not all flowing through the u-bend. Where it pools it is soaking through into the ground, next to the wall of the house.
We recently had this unblocked and it became apparent after this.
The damage is about 30cm below the level of the ground and 15cm below the drain cover.
