How best to rectify?

[Nozzle]

I discovered a hole in ma footings (probably a matching hole on other side of the opening too). I want to block it up just so the footings don't get water logged. I'm not concerned about the structure at this stage.

I have photos when the extension was built (to a budget) in 2012:

(the footings were flooded soon after being dug, he snagged a pipe with the digger, doh!! - dry now)

My current plan is to dig out to reveal the full extent, then shove some engineering bricks in there with mortar as required.

Anything else I should be doing?

The hole is irrelevant to structural stability.
Simply pack it with brick off-cuts and mortar, & then set a brick or two as a facing.
Do the same from inside if the hole is still open.

Although it seems shallow, the hole might previously have carried a drainage run?
Open the nearest manhole and investigate.

fwiw: After the accident, how come you didn't isolate using the external Shut-off?

It's not still open, the rest of the building has been there since 2012 so "established". For this reason, I know there's no drainage (I know the routes for the rest of this, including a French drain)

i was at work when the pipe was snagged. The builder "repaired" with the correct fitting... but it subsequently burst again after he went home. I had a text from my neighbour saying there was water coming through our adjoining fence and did I know about it.... shame I have to have my phone off when at work! By chance, I'd taken a meter reading a few days before. 18,000 litres had passed through it in the mean time



Hillarious!!

If i understand you - there's no sign of any other "hole" except for the one you are now bricking up?
Still dont know if you have an outside working shut-off?
Dont allow the repair to become permanent - replace the damaged pipe its full service length to the inside shut-off with a new length of MDPE.

There is a shut-off at the water meter which is unconventionally is in the back garden and loops around the neighbours garden all the way to the pavement. It's all history now though, I had the snagged pipe terminated instead at an outside tap with the only other connection being a Tee piece to a new pipe that enters the house in a new position.

I don't have any engineering bricks but I do have some concrete slabs (the kind with aggregate in them) which I'll slice up and insert into the hole - once uncovered again. It might not be clear from my initial post but the first 2 images are recent, the bottom one is 2012.
