dream on buddy

looks like a foo foo valve to me

some sort of infrared thermal camera should provide adequate info to generate at least an initial estimate

yeah ive had to do some of this but it was in an underground environment where humidity is typically quite high. We would spray the shotcrete with water as often as we'd feel it was beneficial, and MAYBE take some test cores after 7 or 30 days. Never had a problem but then me...

EP, could you please advise what are the three values that you use , so I can have an intelligent conversation withe HVAC technician when he is testing my house??. I am well aware that most houses leak more than the homeowner recognises. I have a strong background in mine...

Not wanting to hijack this thread , but how does one exaluate the results of a blower door test?? I will be having this test done next month prior to replacing windows in a 2000 sq foot home built 20 years ago. My energy costs arent atrocious but theres a govt rebate plan...

A friend of mine did exactly this a few years ago. I had zero involvement in the project but based on my visual observations these are my questions. How do you proposes that the contractor deals with the inevitable water and snow that will accumulate for the life...

[jiustice delayed is justice denied

I'm going to out on a limb here, and I could be 100% wrong, but your project sounds very much like a small localised marujana grow op. ARe you prepared for the complaints from your neighbours and the visits from the local police authorities.??? Your winter conditions will...

There is absolutely nothing ever built or designed by man that will not eventually fail . All these supposedly safety functions only generate short term "peace of mind" Chernobyl was what , 40 years ago and Fukushima about 20 years ago. We must be due for another nuclear...

Ah here we go again.!!! The underground mining industry was playing with air lift systems about 80 years ago , with rather mixed results I might add. To put this into context, imagine a column of clean water , 3000 feet in height. A column of water only 100 feet...

Littleinches last post make a lot of sense especially if you chose incorporate a pumping flange such that you are able to pump , at pressure behind the formwork. As concrete rises , it will displace the air volume and provide 100% filling of the void. Where you park the...

What is the lateral extent of the cavity , specifically in the X and Y directions ??? You kinda need this info if you plan to use flowable fill

Generally accepted concrete placement techniques do not allow for the airmailing of wet concrete much more than about 1 metre. Also how do you intend vibrating the wet concrete??

cant say I'm surprised that it failed inspection

Thanks for the vote of support guys. I have followed Piereick's advice and reached out to website's owner to see if the previous deletions can be reversed

I had two posts here, one of which had earned three/ stars. I guess at least three posters found my opinions relevant. I have NEVER had a post deleted previously. I can make a real good guess as to who flagged my posts , simply because he did not like my content. I am...

Well , in general we dont try to lift slurry , We attempt to dewater as much as we can which then gives relatively clean water to dispose of as well as a much smaller volume of high solids slurry , This can then be deliberately introduced into the run of mine ore or...

Maximum slope for underground workings is usually 15% and we park wherever we can.

With all due respect to PEinc's abilities and experiences, the wording of his post will likely lead you into trouble. I dont know much about shoring etc but I do have extensive experience with rock excavation. IMO , his post start with the word "If.", In my experience there...
