I would say rebuild it, using the original as a base and taking the advice of commenters. Maybe you could take the place that's blown out and expand there?

If it's ground water, you're fighting a losing battle, it will flood no matter what you do. If it's surface runoff, a lid will keep it out, but all the surrounding saturated ground will leak inside. You'd need to build a water tight box, but then it might just pop out the ground, floating on the water coming in.

It's hard to tell for sure, but I think the only reason the water didn't get even higher than it was is that it drained through the emergency exit. If you want to salvage it, I think it would be best to dig out the entire area, and build it like a cabin and fully waterproof it, and then backfill over it. My personal opinion is that you should take what you've learned, and start a new project that is just called a bunker since you've expanded pretty far from the scope of a spider hole anyway, and maybe see if you have a sport that is slightly higher elevation.

I think the idea and you following through with it was already successful and served it's purpose. Either fill the hole back up and abandon it or use the good, supported half of it for some type of tool or food storage. I think this is R.I.P. spider hole. I know your resolve is unbreakable and you COULD fix it... But I'm not sure if it's worth your time. Onwards to better and brighter projects!

Thats why these underground shelters are okay for their initial use, but give it a few months a year or sometimes more, with out a proper ventilation and gas removal set up then you got yourself an incredibly dangerous hole.

Sadly it seems your cool spider hole is turning into more of a traditional dugout. I don’t know how flat your land is but building the spider hole on a hill might have helped 😂 Keep up the good work!

Finaly you added the underground secret pool. Was about time.

Kevin if you have clay soil and the winter snow has extrem melt off with flooding rains and more melt off the wood will pull apart like it did the weight of water is adding 8 pounds per gallon and that multiply by thousands of gallons of storm water run off ! The run off storm water seeks the lowest level and if it’s heavy clay mixed slush it swells up making the wood push apart. That’s the problem you never poured the concrete to finished the bottom walls.

make a big hole nearby to get the watertable to fill, which will reduce the water table level everywhere else. (this is how Florida was made habitable) also make floors slightly elevated above the ground to allow water to not soak the floor

Dig out the blow out section from the surface. Whether you decide to rebuild the wall in the same place, or what I would suggest, is to expand out that living space to allow for more than one person to be able to stay there at any given time. The floor idea is a must. Maybe digging down a little deeper than you have it right now, extending your pillars much deeper and possibly add in even more pillars as added support, and putting a layer of gravel between the dirt and the walls/floor can help with the water going around your dwelling. Maybe, if your budget allows for it, you could consider adding cinder blocks around the outside of the walls, possibly even rebar and concreted to ensure undeniable strength for years to come.

It's entirely compromised... I can tell Kevin is no engineer. Danger Kevin Danger 😂😂😂

One of the other channels I watch usually wraps the entire cabin in a tarp. If you dig down on the outside of each wall and added a waterproof barrier to the walls and ceiling it would help, then maybe a sloped drainage pipe under the floor might be better than having to run a pump? Although it would mean a lot more digging 😂

@huliluliukuzelula

"not for people who are claustrophobic" i feel like that could be the tag line for this whole series.

soon as you went in and saw the wall blown out, it looked to me as if that was an invitation to expand the spider hole living quarters. lemons into lemonade.

I use to work in the Coal mines we use to have very loud noises that was created by pressure bumps that would be so strong that they would snap large posts into. Sounds like that is what your experienced on a minor level. I would use metal flashing and attach it to you wooden box to keep water from going into the entrance. And definitely, would fix all that from the Top of the ground not inside the underground shelter. If you can install a floor that will prevent that walls from crashing in on ya. Then install a huge sub pump below the floor surface that's what I have in my basement to prevent water intrusion and it works well.

I'm not an engineer or a carpenter so i don't have a solution on that. So glad to hear Kevin that you will improve and continue that project.

need a battery operated sump pump with solar panel. one like a solar pond pump might work as a base then add a battery and a water level switch...add the floor but maintain a french drain like groove around the perimeter that leads to a sump hole. this is just like a concrete basement has to deal with but you built with wood... it may stay wet for years on the other side of the boards and only dry out in the sump during periods of drought or deep winter cold...

SUGGESTION: Once corrected... pull back the forest duff and create a dome of soil above & beyond the entire outline of the underground structure to help divert surface rain away, then replace the duff. The surface roots will penetrate the new soil and claim the new mound as its own, providing permanence to the dome.

Wow a lot of rain at once. Can't wait to see how you fix it. I know you can rebuild her. Have a great day.

So, a wall caved in. On the bright side... nature just gave you a nudge to build-out an extension. Build a room in the direction of the cave-in. That is the only area affected by the cave-in. Everything else is still good. That would give you more room, would be less digging and would allow you to shore up your framing. Great video. Thank you for sharing.

One thing that would help ground water , would be a clay blanket on the surface , far surpassing the spider hole . This would stop saturation from rain in that area , making for alot more dirt that can absorb water before the area is saturated by surrounding ground water . Water follows the path of least resistance (whats already wet) in theory this might provide security for extreme rain like this.

Hello from Minnesota USA! Great episode.

Kevin, unless you have a way to continually drain the water out it may be best to salvage the items stored down there, and abandon this project until dry weather returns. The caved in wall may become a candidate for another exit. Your life and Don’s are too valuable to risk with the possibility of being trapped inside. A cubic foot of water is about 60 pounds; remember this when calculating the weight on the walls and their footings. The mold will be deadly unless you have a way to dry everything out. Perhaps you could convert this into a mushroom farm. For your own safety as well as Don and other visitors I suggest that you secure the entrances shut and focus on finishing other projects. PLEASE STAY SAFE OUT THERE.

Only 5 minutes in but my guess is that it is ground water, but ground water that is raised by your excess of rain. Maybe a lost cause but a bilge pump and a heater might save you in in future torrents. Or cut to the chase an install a bilge pump and dehumidifier.

Guess we know what that cracking sound was! Damn glad you weren't in there when it blew out. Stay safe man!

I am absolutely not an engineer, but I was a designer. I’m also fascinated by history. I know that in Tudor and medieval England, homes were built of wattle: manure, mud, and straw. What if you worked from the outside in, instead of inside out? Make the outside soul less dense first. The wattle mix is lightweight, but firms up with water. Do some research. You probably have tons of pine needles (straw substitute), and you must live near farms. Do a test on a small pit. Just thinking.

The old adage "just because you can, doesn't mean you should" is circling in my head. This was a fun project. I would consider what usefulness this hole might provide. A translucent lid would provide a nice freeze-proof greenhouse. Just remember to ventilate.

Instead of doing a flat wall. Why not try and angle the wall that has blown out into a triangle shape. That way there will be less pressure on one large wall because your smaller walls seemed to of held up good. Great video as always 👍

If your going to dig from the outside to reinstate the collapsed wall, you may as well make it bigger! Like the idea of a wooden floor which will also brace the structure, maybe dig the sump deeper with a false floor and have a solar pump with a float switch to activate it

one word, Concrete. I know it sucks and is expensive, but it's the only thing water won't destroy. The wall blew out when you drained was because you had heavy wet, loose soil on one side, and the water inside was pressing against it. once the water was gone, the pressure was all on one side and it gave.

Looks like the spider hole is gonna get an expansion

12:40 "Clearly, my shaft is falling apart.." lol

Dig an expansion through the broken wall, with a ceiling then put all the dirt on top.

Just so you know, pumping out the water like you did likely contributed to that wall busting open. The water inside the box helps to equalize the pressure that's acting on the outside of the box. By pumping out water you increase the pressure difference between the inside and outside, and put the walls under more strain. You should have braced first, then pumped.

Wait for it to dry out a little, and then....EXPAND!!! Make the room bigger :) Concrete the outer wall, wood on the inside...then put a sump pump and have it pump out of the emergency exit! Let me know if you want help, I might be available by the time things dry out :)

I think your on the right track. A new floor and a sump pump. Also maybe a deisel heater to dry the space out...

You may need some deadman posts to sturdy the wall before continuing with any kind of fix. Also, you may need to correct any water flow from rain to direct it away from this whole structure.

If you put concrete and reinforced steel rebars between your wooden ceiling and walls and the dirt/sand/clay/gravel/whatever behind them, then you won't get any more water in there than in a basement. Some basements have a slanted concrete floor under the floorboards with a bilge pump down there to keep it dry in the rainy/defrost seasons.

My idea is to start over and take out all the wood and dig the hole bigger from the top down and then put you beams back into the original holes and then place horizontal beams wedged between with tarps all around it and under above it and making sure that no wood is touching to the dirt except for the 4 corner beams. Then with the roof on with a tarp on top of that then back fill all the wall with dirt only touching the tarps and bury the top with dirt. Make sure you floor it also on a tarp.

Wow. You've got quite the task ahead of you. BUT! This is also an opportunity. The first thing you're going to need is a dedicated sump hole. This will need to be reinforced with wood to keep the dirt from filling it as the water flows in. So, wood sides, wood bottom. You're going to want it deep enough to sit the sump pump in there, so maybe only a foot or so. As far as the wall that is caved in, there is no saving it as it is... but that's not a bad thing. You're going to need to dig it out from the outside. And since you're already going to be digging it out, expand the room. Build another few wooden walls, make sure they're reinforced at the bottom, middle and top like you did with your new shaft, and build a floor for the whole area. It doesn't have to be wood, but it should be something porous yet hard. Something like stone tiles (like the steps they use for gardens) or river rock or brick or something. Wood will likely rot if left submerged and exposed to moist soil unless it's something like cedar. As you're putting in that floor, you'll need to install some bracing from wall to wall to keep the sides from bowing out again. This bracing can then be covered by your flooring. Ideally, something like steel that won't rust or wear away would be ideal for this. Wood is strong enough to hold back a lot of pressure, but it has to be properly braced. This is recoverable. It's just going to take some more work.

Should put french drains above the hole. You can even cover them up with pine straw and they'll continue to work to flow water away from the hole.

Savage Kevin if you are going to save it then yeah your going to need an automatic sump pump mate. 👍🏼

The water that was pumped out was providing hydrostatic pressure outward, when you pumped the water out which was providing an equalizing force to recent rain, the pressure on the outside overcame your bracing causing the inward collapse. Keep in mind 1 gallon of water weighs about 8 lbs.Wood is not a good material for what you are doing, reinforced concrete that is waterproofed and encapsulated may work better. Keep in mind, hydrostatic pressure can cause huge structures to float, as liquids are incompressible, so understanding water table level is critical. Also, youre better off excavation of a large area, building the structure, and then backfilling. Large area excavation will allow you the ability to lay down 2b stone as a base drain layer for the concrete to sit on top of. Building the way you are now, you are risking getting seriously hurt or killed. Consult a professional.

Maybe line the wall facing the dirt with tarp as well as digging the floor out a little deeper, putting gravel on it and building a wood floor. Create a low spot under all that and drop a sump in that has a floater valve (kind of like what you have in the toilet) that is designed to turn the switch on when it gets to a certain level in that low spot. The water will flow behind the tarp and into the gravel floor and going to the low spot.

The water probably shouldn’t have been drained to equalize the pressure from the outside. Bad situation bud. Good luck and be safe.

Your side post failed because it has more force on it than the corner posts. The corner posts have forces from just as much wall, but because the forces are 90 degrees away from each other the net force is less. Not only that, but as the corner posts shift, the ends of the horizontal boards push against each other. If you rebuild that wall probably your best bet is to brace the vertical timbers from side to side along the floor so the bottoms can't slide inwards. When the ground turns to mud like that you can have several tons of force pushing inwards, but you probably already know this. One thing that I think would be neat is do some mathy stuff and turn your shelter into an octagon with one board length (4 ft?) per side. Your cuts would be at funny angles but a similar situation with the mud would distribute the forces around the whole structure and be quite strong. Since you're digging one side out already you'd be partway there! Of course I'm not the one digging, but to quote Lord Farquad from Shrek, it's a price I'm willing to pay! :)

I think salvage what you can out of it. Fill the hole in having worked in civil construction for 20 years without a lot of external excavation and drainage points it will be very hard to contain it in future events.

Great video

concrete floor poured once the weather is dryer would be the best option, ideally with a plastic lining to keep the concrete separated from the ground itself

I would say your best bet is to add a thick layer of gravel under your floor that would at least run to a drain pipe out your "escape" tunnel. Otherwise the sump pump would do the job as long as the pump and electrical system doesn't break down.
