I was investigating some "anomalies" in my wallpaper, sort of like cracks but not. Long story short, started checking brick work outside and noticed some more cracks. Not big ones you can put an arm in but 1-2mm.

Not sure of my reasoning but lifted manhole in patio and discovered this.....





As you can imagine I'm slightly concerned, especially as when I poke a tape measure into the crack it just keeps going.

Basically this entire patio has no soil underneath it......



Weirdly the area under the deck is fine. What worries me the most, is no soil from house foundations out and as the house is built on a concrete slab, how much erosion is under there.

I've contacted the insurance and waiting to hear back bit in the meantime has anyone else had this and what can I expect happen.

Thanks.

Suspect it will be a leaking pipe (probably soil pipe) which will be washing away the soil around the pipe. Yes best to get insurance to check it out

My initial thoughts were leaky pipe but would that cause there to be a total gap under the whole of the patio?

Could be a leak from the water main. Seems like a lot of erosion just from a leaking waste pipe.

Do you have a water meter?

Sounds like a new patio on the home insurance at least, silver lining & all that... Until it also gets washed away! hehe

Ok. Pics of wallpaper anomalies..





Difficult to get photo because wallpapers so bland, but it looks like the wallpaper has been torn then restuck but over lapping slightly. Sorry best way to describe it. Definitely wierd because it's dot and dab plasterboard underneath.

These are linked across the ceiling by this crack..



Which is over where the stairs are in this pic..



Having gone round the house paying a bit more attention I've found another wallpaper issue in the corner by the French windows in the last pic about a foot long and the French windows seem to have become structural. As in we usually only open one door and now if I open the other it requires a lot of lifting and swearing to get it back. Also the bathroom is above to the right of the last pic. I assumed the was something caught under the door that was rubbing slightly but it's rubbing on the floor so somethings moved there as well.

Looking forward to the new patio though

Thanks

Yep. Pretty much convinced it's subsidence of some sort.

Question is how invasive is this likely to be. I've got a sneaking suspicion this is going to #@*! with my life for a considerable time.

Update. Garden wall 50mm out top to bottom over 5ft.

Keep us updated. Looks like quite a bit of movement so I suspect that there are issues which are probably related to some sort of leaking pipe.

The wallpaper an ceiling cracks are hairline at the worst. Could just be the plaster cracking and/or a little settlement but really noting to worry about. Just fill them in. If it cracks again in the same place in a few years then perhaps there maybe cause for concern but unless it greater than the thickness of a pound coin I wouldn't worry.

Also be careful getting insurance involved as if they record your house as having any sort of subsidence it will make it harder to sell in future and potentially devalue it. I'd get a independent inspection first e.g. friendly builder / surveyor / structural engineer and then if the decide it going to be mega bucks to put it right then get insurance involved.

Silver lining? Maybe not, if he ever intends to move...
