Hi,

Just bought a new build house and noticed a hole in the grass right next to the house. When I step on the soil around it the soil collapses as you'll see in the video.

I've also put a picture of the hole.

Does anyone know anything about subsidence? Could this be part of natural settlement? The builders of the house are going to have a look at it but I wanted some other opinions from people who know about this.

Thanks

Everything else looks level so doesn't look like subsidence to me. Is there water draining into or through it when it rains?

Is there a water pipe (either in, or out) under there?

Hi,

Not sure about when it rains as we are not living there and only settled on the property at the weekend.

It is very close to where the water drains out. Maybe 2 metres away

Thanks

Thats extremely close to the house

You'd better get a 2nd opinion, from someone not involved in the actual build or sale .

Go to Council and get plan of all underground services on the property … as others have said, it looks like a water leak in that area. 

 

Being very localised (the rest of the ground seems solid enough) a drainage professional should be able to detect source (they both prod, listen and use ground radar for this stuff).

Agree with this. After recent works we've completed I have increased respect for drainlayers!

What happens when you poke it with a big stick :), it is dirt at the bottom, P-metal, or a pipe

 

Its likely that area was excavated for the house slab, its likely been backfilled at some stage, and someone may have done a pi$$ poor job,

 

Its looks like you have  storm or sewage around that side of the house, so its possible a pipe has broken

 

But I don't think your house is any major danger of being swallowed......

If it's anything like the new build next to us all the soil could be sucked down the drain and the house would still be sitting on the 40 driven piles under the concrete slab.

 

It could be as simple as the backfill around the drain pipes wasn't properly consolidated and surface water has done the job. It's a new build, let the builder do the sweating.
