[@SHOE53]

Those jobs like that one can eat the man hour up it look pretty simple but once you get in to it there more work then one would think but bye the look you guys did a very nice job.

[@tucobenedicto109]

Sean love the work and the cheap method with the PVC. At 24:45 there is sunlight but the catch basin. Maybe when it's full it flows from there causing the damage. It needs to be regrouted or brick work. Not sure if that's you or a sewer contractor. The camera in the catch basin manhole would do the trick.

[@GCFD]

That's a great observation. The basin is like 8' deep and 24" pipe so I don't think it's overflowing. Also, there is much more water flowing down the curb of the parking lot and I'm convinced this is the cause/provided the energy to do the damage. The drainage basin was the exit point and the place where all that soil left the area (as muddy water). What do you think?

[@tucobenedicto109]

@@GCFD you got the point. Where did all the dirt go? Right to the basin then down a pipe. Good thing on thinning out the mix and shooting it that way. It might have sealed it. On that side. Concrete seals everything. I've seen a pin hole in a roof dripping into a store. They put a bucket. The next day the rain blew out that section and took down some drop ceiling tiles. Sometime it's just a small hole that can do that!

[@somethingelsehere8089]

Holes through brick into catch basin at about 25:39. Considering the final fill with concrete it is likely moot.

[@GCFD]

I forgot to mention the basin is like 8' deep. You're thinking the basin backs up and flows into those holes? I don't think that's the case as the basin has a 24" pipe leaving it and it never backs up into the parking lot.

24:00 sinkhole footage is unsettling. You all are heroes

Ronald can outwork most young people today

[@GCFD]

[@mr2miach]

24:07 "ish" if you pause around that time frame give or take a few seconds, you can see light coming in through the brick wall that surrounds the drain inlet. That's where your water is coming from for that one section in the parking lot where you were able to climb into the hole. Willing to bet that's going to keep eroding the soil around and under the gravel you put in there.

[@GCFD]

I disagree. I think the water was coming in at the parking lot and flowing into the basin through those holes in the brick. The basin is like 8' deep and represents the exit point of the water (muddy water) and where the soil left the area. What do you think?

[@mr2miach]

@@GCFD That's basically what I was stating. The water from the parking lot is going into the drainage inlet and worked its way through those bricks. That's what washed out the soil to create the hole you all were able to climb into. My point is, those bricks are still going to allow water to flow through, which then will seep through your gravel and concrete that was poured on top of the gravel. Not to mention, I have high doubts the concrete made it all the way back filling the entire space. Probably filled the majority but any gaps or space left behind is just another entry point for the water through the bricks to wash out your repair, or at minimum, damage it deeper down. Not saying you all didn't do a good job, saying, that repair needed to be fixed starting at the parking lot drainage inlet and seal the other side of those bricks.

I know property managers have budget constraints, either because the property or properties aren't overly lucrative, or the owner is frugal, but some things you need to drop coin on to avoid spending even more later. Especially if it could cause damage or injury.

[@donaldmendes184]

What we do with situations like your showing we use slury , it's conbentaion of sand and concrete, It get into voids and cracks , plus don't need to compact it. It hardens up but yet you need to dig thru it it stays solid, but also easy to dig thru . Get thru your concrete supply company.

[@Stratos53100]

Another Feature Film...That hole was a doozy and kept going, luckily it didnt collapse for any bystanders etc.. Initially thought you were back at the complex ( with the other flooding & basin work ) though after you said that its another place. That upper part may have gone farther next to the edge of the parking lot though packing the concrete on the edge was good. Could be never ending...At least for this part should be handled. The grading there was the only way. Pizza Qty + 1

[@GCFD]

Thank you! This was an interesting one for sure. I forgot to mention with the hole next to the basin....we could have filled it with concrete but I didn't want a 3' thick chunk of concrete that someone in the future might have to deal with. That's why I decided to pack washed stone in before the concrete.

@@GCFD - Reffering to the gap on that asphault edge under the existing farthest slab when you got it with the drill...

[@randallweaver7034]

Another great project! 24:35 there is sunlight showing between brick and concrete. This can allow water into the ground creating a sink hole. Perhaps parging/plastering the interior of brick will prevent future sinkhole.

Seriously that is a nice apartment complex, they have these people I'm sure paying top dollar to rent there, they can afford to spend the money they just choose not too... They made your job so much harder because they wanted to be cheap. Seriously I would have never done what you did. I'd have opened it all up so you could get the stone it, tamp it down and do it right from the bottom up. I get they were getting tired of having their concrete undermined bit being cheap,is what got them in this mess in the 1st place... time to spend the big bucks and do it right.

oh man, Sean... that all needed to be torn out..... that drainage basin is likely overflowing and causing all that issue.

[@GCFD]

[@Chestnut0923]

I thought the idea was to get flowable concrete into the washout under the sidewalk? Not putting the flowable concrete left the giant void under there. So the new concrete just covered the issue without fixing it.

[@GCFD]

The side was still very solid with how thick the concrete was so the property managers were happy to leave it. We fixed the cause of the erosion, which was the main issue. 👍

[@Chestnut0923]

@@GCFD I saw the fix but under the slab you didn’t remove there is going to still be a huge void which will make that concrete weak. I’d be worried about that

[@vjf9052]

I absolutely love watching your work and how you explain everything. I've been a fan probably since the beginning. I'd give just about anything if you were in my area after a truly terrible experience with a "professional" company that created more problems than I already had. Although they came back three times to try to figure out why their system collapsed, they refused to do anything to fix it. The good news is that I've learned so much from watching your videos, when a friend referred a contractor who came out to look everything over and give me an estimate recently, I was able to ask him intelligent questions and figured out pretty quickly he had no idea what he was talking about. Next! Thank you, Shawn!

[@philh8829]

You can tell by the asphalt patch that the sinkhole was fixed once before and the fix failed. The brick lined drain is like swiss cheese, and washing that area out. Drain needs to be repaired.

Leaking pipes cause sinkholes. Putting a CCTV down to the street from the base of the downpipe could've located a problem, of say broken pipe, or draining into dirt. New pipe, or construction of a French drain would be an effective permanent solution.

[@calebrusso3773]

Great investigative work. It’s always interesting to see you getting to the root cause of an issue trying to rectify that, instead of just repairing the issue / disregarding what caused the erosion / drainage issue to begin with.

I like my solutions to last and so we need to fix the original cause. 👍

[@rjbiker66]

It's formed like a miniature cave system. Probably find the carpark sinkhole is from mains/hydrant water leak. Have to ask what the existing patch in the carpark asphalt was for.

The foundation for all of that was very bad. Seeing the image underneath…i question the fact they even had a foundation. Also a foam solution would probably be easier… but not sure what would be the cost for that. That will involve just some holes… that are already there.

[@GCFD]

I don't like filling with foam because that introduces another material into the mix. I like soil and new concrete because they fuse and form waterproof layers that don't lend well to water flowing along them.

[@TorMelkson]

Looks great. Bummer they blew all the seed and straw away. Did the management ever find the cause of the water leak running onto the road? And what the fix was?

[@GCFD]

Yes there was a cracked potable water line under the parking lot. I think it was a Tee fitting that cracked.

Good investigative work but that sidewalk came out so uneven and out of whack. It was bulging out from the form and too high in the middle. It's going to puddle like crazy. I'm assuming the home owners association didn't want to pay for a full crew to come in, but at the same time it's going to result in more issues in the future.

Evening Shawn, those wee sink holes are the start of something bigger. They start that size and grow and grow. Its been raining really heavily in Scotland and we're at the bottom of a row of house on a hill next to a forest, so the water flows down the drive into the drainage channel in front of the garage. Since I started watching your vlogs Ive been watching the water flows, and cleaning gutter and channels and checking the concrete to make sure everything good. The water passes us and travels further down the hill. I check the whole drive and paths in the garden to see what is happening with it. Great work!!

I know you mentioned cost as a limitation by the customer. However, since you were taking out a concrete section, I first guessed your were gonna put in a french drain along the steps and building side of the sidewalk to then run through a pipe through the new section of side walk. Why? It would collect the water without it having to go over the sidewalk. Any thoughts?

@@GCFDCorrect, I agree in general. However, given there was a sidewalk, I thought it would be annoying to have the water flow over the sidewalk and any other debris, especially if temps get to below freezing. Thus, a FD would collect both the surface and sub-surface water to then route through a pipe in the sidewalk to the asphalt. As Always, your workforce is amazing!
