By the way, if you're ever put steel in concrete, make sure there's either waterproofing on the steel, a sacrificial electrode, or at the very least zinc nearby (i.e. a zinc coating). You can go on a wild ride into looking into zinc repairs on existing pillars submerged in water for bridges. The zinc gets electrolytically sacrificed to protect the steel. I think the civil engineer youtuber recently had a video on it too.

That'll help keep the rain out for a few years at least. I wonder what the hole looks like after the rain. At least you could hear your pump running so it shouldn't be full. Hope you feel better too.

Slab looks tidy. Like the drainage channel . good place to plant some bamboo. I was told a healthy glob of exterior pva glue in concrete makes it waterproof. And a sheet of plastic on the earth to keep the surface dry. I was looking at the depth of the slab , but if I had recently dealt with a back and shoulder issue , then its a that will do situation. Camera faceplant double ! Ace ! Hope nothing broken. That pallet step area, rekon that's your culprit. You sending water next door? How about outdoor sump pipe the water further down the hill to a water butt, dunno if your shed has plumbing , but for small concrete batches or hand rinse . Was there a gap under your shed slab when you first cut through. Tends to happen in water traffic areas. Always a pleasure, see you next week.

Thanks mate :-) I admit the slab was a rush job but I needed it down asap to save the bunker getting another deluge and yeah it was a slog with my back still a bit tender. Camera survived LOL. The water is draining onto the property next door which is actually all part of my property so no problems there.

BTW there was a cavity under the workshop floor and a lot of ground water.

Hello Lex, that “reo” pinned to the ground will do nothing, it needs to be 30-50mm up from the bottom or down from the top

I put spacers under it but only about 15mm thick so maybe they needed to be thicker. I only weigh 70kg and it's only me that will be walking on it so hopefully it will hold up. Guess time will tell.

Honestly, it looks like the mix is so fine, that it will definitely do something.

Not to put you down or anything- you *are* doing this the way you are happy with it, but concreting everything and even adding steel reinforcement is not very "budget", if anything it's the correct and best way of doing it. The name of your channel suggests more MacGyver solutions, anything to keep costs down :p

That's a valid point - to be honest I was going to try and do it more budget than I am but it does slow it down a lot and also I do want the end product to be a useful space. Hoping the overall cost will be significantly less than a commercial bunker whilst uniquely fitting my needs.

@@LexsBudgetBunkerBuild honestly, doing the labor yourself will 100% make it significantly cheaper than commercial, because for some reason a lot of tradesmen OVERPRICE like MAD. We're talking entire month's salary in a single day.

@@LexsBudgetBunkerBuild and that's all that matters.

Mate don't put steel in a slab and then pin it penetrating into the ground. Electrolysis will attack the steel reinforcement. When the steel corrodes inside the concrete it will expand and ecplode holes through your slabs. Big no no.

How long will it take to explode? The slab next to it was done the same way 30 years ago and seems to be ok.

@@LexsBudgetBunkerBuild It's not been studied very well, but if the steel is directly exposed to electrolytic solutions (i.e. dirt with high metal content and salt) it will corrode crazy fast, even weeks under the right circumstances. It's true that all metalwork needs to be waterproofed prior to installing inside of concrete, or at the very least, the concrete is made waterproofed. All concrete is POROUS - water slowly seeps through it, taking anything with it that's in the soil (osmosis).

Lol not like a bomb but it will blow holes in it. With how low it is in the concrete it will blow out the bottom. It will take path of least resistance.
