Subsidence in Bristol

[Pocster]

I posted about this property a while ago. It has got worse. So really need recommendations. Not keen to google, click 'n' hope.

I see lots of "resin" fixes this viable?

TBH even with recent photo's it looks pretty much the same.

I notice on the landing ceiling some obvious damp so maybe render cracked on roof?

The main cracks are on a shared wall with neighbour i.e. terraced house.

So even with resin how do they fix that?

Going to have to get insurance involved for 1K excess ...

 

What I dont want really is subsidence fixed 1k poorer and then I still need a roofer/plasterer and decorator!

of note (maybe) there is a drain running under the property (front to back) but thats on the opposite wall

That is more than a resin fix .. crack appears wider at the top than bottom so too is falling away - probably being pulled by next door property. Have they had any major works done? Cellar dug out to make it deeper etc.?

It's buggered buddy. One of your rentals ? I don't know if there is still a stigma around houses that  have had subsidence. Patch it up and flog it ?

Feels like it's time for a professional? Find an SE to give an opinion?

Nope they've had zero work

Yeah I was thinking that. But wont an SE just say "yes subsidence" , cctv down drain to eliminate that as potential cause i.e. collapsed; and then tell me to get a professional subsidence company in?

 

The most likely reason is ground shrinkage - as the entire area is mainly on clay.

But how do you "get under" a shared wall that isn't directly accesible ?

@Pocster if on clay it could be subsidence or heave ( your part is lifting when the other side stays put, is your floor and window cill still level? If yes then it’s the side that is subsiding and as you point out, access is the problem for under pinning or jacking. I would put some movement monitors across the cracks (can be as simple as a couple of pieces of tape with marks to see the movement). If movement has stopped then you can look at stitching.

Thanks. Floor window cills all fine. So how do they access that party wall?. Neighbour isn't helpful as presumably they want me to sort and pay the excess whilst potentially benefitting. 

Lets assume the movement has stopped ; how can we be certain there wont be more?. I have monitored it for a year now doesn't appear worse. 

So what would/should a contractor do?

I'm going to push the insurer to supply a loss adjuster/subsidence specialist - I hope they see it's in their interest to establish cause and remedial work rather than me "try"

Well @Pocster , hair  won't grow round this one.... 

 

A quick  look for a cracked foul drain scouring out the pipe trench ? Cheap, quick, easy.

yeah but as I said drains on the opposite side of the plot . Managed to get hold of the neighbor (another LL) and his tenants have reported cracks in the same place their side - so I'm on insurers back now.
