I have an inspection pit just like yours and yes it fills with water. Following with interest 😁

Really enjoying this channel, looking forward to seeing more

Good video again 👍. Shame about the results be thats how we learn . It might be worth trying a dry mix of sand and cement 1/1 or postcrete when the water table starts to decrease. Ground moisture will activate the setting process resulting in hardening. Once hardened it will create a better surface for tanking application resulting in a better seal. Once sealed and dried, then apply another mixture of sand and cement 1/2 over the seal to protect the tanking. Or just fill it in 😄 , regardless I will tune in again .

That’s what it’s all about well done it’s good to show failures as well as success to me it shows the honesty of not only the channel but also the maker keep going your doing well

Thanks Phil. I’m sure there will be plenty more mistakes along the way, but it’s all one journey.

Amazing video - I was in this exact situation last autumn. I taped 2 DPM membranes together to line my pit and concreted they floor Little did I realise the tape had failed in places but I cracked on and ignored the fact the ground had little puddlea. Blocked up the walls and low and behold I was left with a swimming pool; especially bad after a stormy night I took the whole lot down Over the winter and just this week I am back on the project. I have done a single liner and some more concrete on that. The hope is it ranked with the liner but if I’m honest it’s tricky filling a hole 6 foot deep walking with wellies in concrete and feeling stones under your heel hoping your not piercing the liner We’ll see - Thursday I play to start blocking. I think slurry is supposed to work well, but does require a dry surface to start with I spent many a night last year staring into the hole at the water trickling in - I think they call it hydro static, it’s a huge amount of pressure based on the mass or something so only a drip will be constant; won’t be able to slurry it when wet. One option is you could line the hole and concrete and then block up bringing the sides in but you have a stronger chance of keeping it dry then

Props for showing your mistakes. I'm looking forward to seeing how you get on with finishing the pit.

I’m going to have another go in the summer and hopefully the intake is less.

another interesting video! keep them coming 👍

Saw your comment moment on woodworking Facebook channel . Im also an aspiring woodworker although will be a couple of years before I can get into it as have loads of house alterations to sort first . Looking forward to watching your journey though . Liked the video . Hope it gets sorted ....

Having underpinned my entire house and built a 50sqM basement alone let me tell you how to do this! Dry with towels as much you can, Quick set cement Mastercrete green stuff to make concrete min 150mm thick, put mesh 4/6mm raised 50mm tamp it flat. Next day or 6 hours later......... KA or other brand filllet seal (rapid rapair mortar) on all wall/floor junctions, ie around all edges, smooth off at 45 degrees with a pipe, then slurry 10 mm up above fillet and all over floor, two coatings.... job done.

Exactly!. Unless I missed it, it looked as though slurry has only been applied to the floor whereas ALL surfaces need to covered for tanking to be effective - with special attention to anything below ground level.

Are they thermalite blacks? If they are, they are porous and will always allow water through.

What did you end up doing with the pit?

The waterproofing should have been done at the time of construction but as they failed to do it you now suffer their error in construction. Even if you managed to stop the water ingress at this stage it wouldn't last for ever unless you're prepared to spend a lot of money but as you won't be using it then a total waste in my eye. My advice at this stage would be to dig a small sump hole where it is the lowest in your pit and most of the water will run too and drop your pump into it, this way you can run your hose out the garage and just turn on the pump when you need to drain it, you can hold those floats on the pump up for a while longer to get more water out before getting the vac out. Good honest video bud.

I’m glad I had a go and fairly early on I had my doubts it would work. You reckon it’s worth another go in the summer or would you just fill it?

What did you end up doing to fix this?

That's a shame.... 😟 Do you have a plan for what you're going to try next?

The company who I purchased the water plug from sent me a replacement for the damaged tub , so I am tempted to try again in the summer. Hopefully we have a dry summer. Worst case scenario I will just do exactly what you did. I am having my front garden re done and I will have several tons of rubble which would easily fill the pit. That would certainly be the easy choice.

I’m going to have another go in the summer. Hopefully we have a good dry spell and I will take a slightly different approach and fillet the corners to reduce the intake.

Use hydraulic cement onwalls and floor(sets fast but waterproof)

slurry looked to thin 3 parts slurry to 1 of water, not the other way round.

Damn! You got an inch of water overnight? How close are you to sea level?? Concrete block is porous like a sponge. Rubber roofing tar on the back side of the block should solve your issue, but this will require cutting back the opening and digging around the pit. Problem is you still have the pit floor to contend with. I am trying to open up my garage floor right now and not create the problem you have. You can bet whatever I build, it will be sitting in lots of thick plastic sheeting and covered with 5miles of tar! I'm on the fence pouring walls, laying block or using 1/4" sheet steel. There isn't much online on this except for basement stuff. Same idea, holding moist wet soil from penetrating a subterranean structure. I'm pretty high above the water table, but rainy weather will leech through soil and travel quite far. If you wanna see what I'm up, this is it. kzread.info/dash/bejne/n6mr2KVuedLAdM4.html It's going 8ft in the ground in my garage so yeah, I understand the importance of it being extremely dry! Fingers crossed you get this, SUBBED!
