Underground den

I think everyone needs to chill out a bit... he's 6... how far is he going to dig?

When I was about 8 or 9, I set out to dig a coal mine! That there was no coal in our area didn’t matter, I got all of about 18” down before I got fed up & moved onto something else. (Probably involved matches & flammable material)

Hence the desire/need for coal......

When I was about 8 ? Summer holiday in the South of france, Morris traveller, tents, campsite, near the sea.

Can I dig a hole with my spade ? Go for it.

Hours later, it was pretty big and deep, the owner turned up and demanded I fill it in, before there was an accident.

Near me there are caves that we used to camp in as kids, sadly a lad died a few years ago when he was in there and a big bit of roof fell on the poor youth, i think they are now closed off,

I remember that, I knew his dad through work

we used to dig a hole on the mud footpath in the woods and put twigs across it then cover with docking leaves and spread the soil; back supose it was luck no one seriously hurt themselves falling in it seemed the fun thing to do as a kid

The sharpened bamboo stakes went a bit too far. Still, the napalm and DDT put paid to your antics I bet!

when I was a child, I found a load of bottles of DDT, I used to fill a water pistol with it & shoot the wasps around the dustbin. It’s surprising I haven’t mutated, wife might say I have, or my nuts shrivelled & fallen off or something

Iirc it stopped sinking and they had to add a few hundred tons of weight to get it sinking again?

Correct, as a result of friction from the soil, so when they did the other end they made the bottom of the caisson slightly wider than the top and that solved the problem.

Did not yet

My job basically starts with drilling holes in the ground, trust me, water can appear at the most unexpected moments

Happens even to the professionals...

Hi, ISTR in Lake Peigneur in Louisiana they were test boring for oil into a lake bed and an abandoned mine was where it shouldn't have been and they ended up draining the lake into the mine.

I think it was a working salt mine, and the drilling co had to pay the salt co millions in compo, vids on youtube of everything getting sucked down.

Didn’t it get spat out again in the following days and the boats just re-floated?

I think the idea of a semi-underground hobbit house type arrangement sounds easiest / safest. The girl wants one too so maybe something with a tunnel between. Will start looking out for suitable containers, I won’t be buying anything new at the prices I’ve seen. IBCs look ideal but a bit small. Are they one size only?

 

[Onoff]

Was it on here that someone was experimenting with cement / concrete soaked towels draped over a framework and left to harden?

How about a geodesic dome(s)?

So much for this WON'T be happening...

Yeah well he won’t be getting a full on underground secret lair complete with fake volcano and 360 degree CCTV system, but the pair of them have been bugging me about this for ages so they might get a semi buried used diesel tank covered up with turf nicked from the school playing fields and a periscope made out of an old drainpipe.

Well, sort of. The place was wrecked though.

I think some of the barges did come back up again, the video description has all the info.

It was I'm sure discussed on here and a video of the company you refer to put up. It was in a thread on potential workshops.
