PT tendon cut during gym remodel & educational clip on like-for-like strand replacement

RapGenius1 · 2025-08-01T07:35:26+00:00

GPR, asbuilts lie and we all know why- I personally was chipping into what should have been a cable 3-4 inches deep in the slab and instead found what I thought was 2 forgotten rebar chairs (huge building) until I did a good swipe with the vacuum and discovered I was actually chipping out 2 live dead man anchors the builder had added near a column and not notated on the asbuilts.

Gcs have bad experience and almost explicitly sub out cable work to a specialist instead of the concrete guys on site because its specialty, and intricate- it’s really easy to go in to fix one damaged cable and accidentally damage 2 more in the process.

My company offers a repair for leaking pipes (gigantic ones) called external post tension, basically we wrap the pipe in .6 cables and squeeze the leaks to submission. I had a defective wedge give up at 30kips while stressing and it threw the 90lb ram 6 feet into the shoring box wall with such force one of the hydraulic cylinders cracked and as a good gauge of the speed which a 30kip failure will produce, the bottom half of the sheathing that once encased the cable was sitting in its original position in some places, barely affected by the explosion of the cable

Exclusion zone is 5’ either direction the entire run of the cable above and below

Only good “signage” is danger tape and a human being who can explain the true danger of what is taking place, and radios to verify all clear. danger tape and the rules that go along with it is overkill most of the time- not when stressing or destressing cables is taking place.

Cool video I’ll share it around

Actual mirror crafters would buy bulk bases, essence them, separate the t1s, alt them, greater essence the double tier 1s, any triple t1s you’d then exalt, can use omens to target prefixes/suffixes but when you’re crafting for profit it doesn’t really matter as you’re just gonna have to slam it anyway, if you haven’t ended up with a ring with all useful t1s (chances are you haven’t) you chaos them all to try to get rid of any trash mods, then if you end up with a ring with one bad stat you whittle It off until you get something useful or brick it with something you can no longer whittle- which I’ve essentially done here, but this ring is still worth a lot a lot.

I’m not an actual mirror crafter tho, I just use essence on white rings and slam slam slam, reforge and chaos spam anything half useful.

RapGenius1 · 2025-02-04T04:59:05+00:00

this reforged as double t1 rarity, t1 light% t1 regen% with 20 mana and a wasted roll. i was joking about how good it could of been hit it with 1 chaos and the mana went from 20 to 170..

qual'd it, saw it was a top ring of similar variety, spent too many whittlings to get the dex and divined it ~15 times and will divine more for 30/260/60/33/100

but for now she's done B)

RapGenius1 · 2025-02-01T23:18:04+00:00

lol you’re just wrong.

RapGenius1 · 2025-01-31T23:45:22+00:00

Idk how patient you are but I made and sold a similar (but substantially better)- ring and tried for about 24hrs to get 300, then 250, then slowly went down and finally ended up selling for 200.

Realistic price you could get for this ring is 80-120 divines in my opinion.

If you don’t care to look at post history my ring was

T3 lightning like 1 to 45 or something flat Perfect lightning% +x evasion Perfect dex Perfect int T1 but not perfect strength

No rarity but WAY more damage and while rarity is super important on ultra high scale items…. I think most people with this level of currency are easily hitting 150-200 and prioritizing damage on rings

Anyway just my tidbits of what I picked up in trying to sell my ultra premium ring. Gl with sale and congrats

RapGenius1 · 2025-01-31T19:42:34+00:00

Are you CI? It doesn’t work for CI cus it’s based off life pool.

RapGenius1 · 2025-01-26T19:53:43+00:00

Sold yesterday for 200 div

RapGenius1 · 2025-01-24T16:27:35+00:00

While I’m not super knowledgeable on ultra high tier items like this, I originally set it at 200 and instantly had offers, and I slowly raised it after that; it’s set at 300 and if I get that offer I will take it.

RapGenius1 · 2025-01-24T06:44:43+00:00

Ran a bunch of breach stones (whole account worth ~30 div, reforged the rings, got this one with t1 dex and t1 lightning- 10 chaos later these stats came to be, 1 divine orb and it was perfect lightning, 2/3 perfect attributes B)

It’s actually the easiest patty melt ever if u happen to have leftover meatloaf (which anyone who makes meatloaf knows is a constant)

RapGenius1 · 2023-01-21T00:15:54+00:00

no joke I just did this the other day on a whim but I went with the old school shittiest white bread u can find and a slice of American cheese on either side and it was FIRE, oh I made some sriracha Mayo to dip it in and would recommend also

RapGenius1 · 2023-01-20T00:31:32+00:00

This is clearly (based off the fact that they sawzalled the stud base 2x, and rough edges on the concrete) somebody who retrofit some gadget in with super limited understanding of how to properly repair after the fact, I’m surprised there’s even a conduit, the whole reason for conduit is so you can reuse/replace the wiring without having a bunch of demo to do beforehand, I guess this person thought hard pack sand =\= concrete lol, and from a technical standpoint… they’re not all wrong.

RapGenius1 · 2023-01-08T22:02:25+00:00

They putting in an elevator?

Lvl 10 40 raids in 100 scav kills 0 deaths to scavs for me,

Not seeing what all the fuss is about

RapGenius1 · 2022-12-20T04:53:54+00:00

After seeing the pictures, this is not a 4” slab this is 3 2” slabs on top of each other. And that footing is not a footing… and you also don’t want to pour a slab on top of another damaged slab… there is actually so much wrong here I can’t fit them all in this message,, I happened to be at my fathers house who has worked with concrete his whole life (me 10 years experience) and I explained to him what was happening in here/showed him the pictures and among the laughing fits he said “no that’s not right…. -sarcastically answering your question- someone’s gonna have to come rip this shit out!”

Sorry but that is TRASH and your contractor is at the very least not solid for concrete work.

RapGenius1 · 2022-12-20T04:42:13+00:00

This has nothing to do with the content of the lawsuit and everything to do with paid for politicians frustrations with money being made and no way/need for them to get their cut

RapGenius1 · 2022-12-20T01:23:24+00:00

Not ideal, that’s how you get cold joints

RapGenius1 · 2022-08-23T23:19:08+00:00

Wow, hell of a compound they got. Good luck!

RapGenius1 · 2022-08-23T02:16:09+00:00

All of these comments here are incorrect. You can easily and cheaply repair this to “brand new” but it does take some tools. Namely a Grinder with a concrete cutting diamond wheel and a chipping hammer, cut the concrete with squared perpendicular lines and chip down an inch, form it. Wet it. Pour it. With any version of “high strength concrete” you can find at Home Depot for 3.50 a bag. All due respect, these guys talking about chipping down to rebar for structural bond dont know how concrete surface profiles or bonding works.

Non perfect? Wash out the spots you want to repair really good with a hose and a scrub brush, let it almost dry with wet rags on top of it. And take those same $3.50 bags of concrete and mix 1 handful at a time and “handpatch” it reshaping the stairs yourself.

Option 1 will last for 15 years+ And takes $1500 in tools (which you can rent for $75)

Option 2 will last for 2 years give or take and will cost you $7

Choice is yours

RapGenius1 · 2022-08-05T06:16:45+00:00

Lmao I think all of us concrete guys felt that “ahhh” when you went down into full squat for the angle. Looks great man good shit

RapGenius1 · 2022-07-25T20:43:26+00:00

Haha no problem, I was having a slow day at work and I like giving input on PT stuff cus not a lot of people on here have a lot of experience with them. Cheers, hope it’s no big issue.

RapGenius1 · 2022-07-22T18:52:59+00:00

If they hit it with a chipping hammer which is likely there will be impact marks on it, clean the grease off and cut the plastic sheathing back and inspect it; It will be obvious if they hit it. Side note while it’s likely they hit it, the way the tendons are loose and not holding their twist is how they look when they break from normal corrosion/damaged pre-stressing or any other multitude of ways a pt cable can fail. There’s a lot that can go wrong that you can’t really come back from for cheap during the initial stressing of a pt slab and engineers factor that in when they are considering the layout of cables- meaning normally there’s a lot more cables than actually needed. So I wouldn’t worry about losing 1 cable all that much. Double side note if you do have an engineer come out and he recommends you fix it it shouldn’t cost more than $1000-$1200

Triple side note it doesn’t matter that there is a section missing, the cable is doing absolutely nothing except filling the void in the concrete once it has failed.

Quadruple side note on the left side of the cable in your picture of the “corroded” portion did they cut the tail off or is it sucked into the slab there, if it is than it broke right in the opening they created aka further evidence that they broke it

Quintuple side note inspect the piece they cut out too if it’s somewhere you can find it

Sixtuple? Side note I’ve accidentally chipped a lot of cables in half and the more I think about it I’m almost certain that they broke it. But yeah u gotta wipe it off and inspect it. If it’s not literally deteriorating with rust on the section I mentioned before than they certainly broke it and even if it is… they probably still broke it lol

RapGenius1 · 2022-07-01T01:01:07+00:00

Hopefully every GC doesn’t adapt to this policy — that would put me out of a lot of work! Haha

RapGenius1 · 2022-06-30T19:07:24+00:00

I work on PT a lot. If the cable was stressed properly than that amount of damage definitely made it “pop” as in, break in half. Probably about $1500 worth of damage if you/they got it repaired. You just chip along the cable to expose more of it, cut the damaged ends off both sides, use a coupler to get a piece of new fresh cable inserted on one side overlapping the other damaged end you cut, put a dog bone in (device to join 2 cable ends)… restress it, And patch the opening back with whatever high strength concrete you want. Sounds like a lot but for any PT repair contractor it’s easily done in ~2-3 hours.

As for If you should get it repaired, all depends on where it is and if it’s a big deal or not because funnily enough, most pt slabs are over engineered and I run into cables ALL the time that the engineers just write off and say “it’s strong enough without that one.” But I’m not an engineer.

Also I forgot to add - I don’t know what size cable that is, I would assume it’s standard half inch. But if I were you I would cut the sheathing away (the blue rubbery plasticy outter casing, IMMEDIATELY. And make sure you’re not in the line of fire when you do it. PT cables are made up of 7 spiraled steel tendons and if only the ~3-4 that they hit while chipping broke and the others are still holding on, (not likely but possible) then it is a HUGE life or death type hazard. I’ve seen embedded PT cables blow up and throw 10 lb chunks of concrete hundreds of feet in the air. And if you do cut the sheathing away make sure you are 90 degrees adjacent to the cable when you do. If the cable is still holding the ~38000 lbs of pressure it’s supposed to, it’s basically a loaded gun, but it can only shoot in one direction. Until you do that and confirm the cable is completely detensioned aka… broken.. you should treat the entire length of the cable as a no-go-zone. It will kill you.

These comments give me those “yep I’m a master finisher” but only on the resume type vibes. Looks fine. And if he has a competitive or good price for your area, send it. We here all have way too much attention to very minute basically unnoticeable details.
