I noticed you go back when it is raining to see your work at work and I think that is great!!!
👍 Thank you!
Love the rain videos at the end of all your videos to show the fruits of your labor!
Thank you! I like that part of the videos too.
Such a large site with long distances requires more depth at the outfall. Lot of work, but I like how your guys hang in there and how your concrete team can help with the grading.
Yes! This job was a major pain to get our fall correct. You can't fake the results! It better not be flooding anymore after we finish.
Nothing better than the feeling of satisfaction after you walk a completed job and you’re pleased with the work
Agreed! Especially when the water problem is solved. 👍
the place I rent had the same problem, no drainage.... had water plants growing in the flood areas, until I cut trenches to the storm water drains, now its nice and dry.
Nice! I'm glad you got things dry.
I’d love to see what your new installation looks like inside from a pipe camera, the type the jetters use. Just for us watching. Also to make sure nothing is crushed after machinery drives over it.
I have thought about buying a camera system but I haven't done it yet. I think the Ridgid seesnake is the one to get.
You guys should invest in some Rigid straplock strap wrenches for seating those larger diameter pvc lines when gluing! They make it so much easier 🙏🏼 great work as always
Awesome!! Great install. Thanks for the rain shots at the end.
Thank you! Thanks for watching, more videos coming!
Great work done Shawn. I'm sure your customer will be happy.
Thanks George! The customer was happy to have the issues resolved.
Why his is so satisfying to see water coming out of that pipe at the end. You guys do awesome work without cutting corners, great job!
Thank you! I think so too! I love seeing that water coming out.
The best part of your videos is showing the “fruits of your labor”!! That’s what us
“water-aholics” and civil engineers want to see!!!
Where was the concrete 12-14” culvert pipe coming from?
Looks like a small retirement facility…..I bet they were enjoying the entertainment for a few days…….
Thanks again Shawn and the boys!!!
I did residential construction, remoding, framing,roofing ,siding, windows, doors, cabinets, sunrooms, 12 yrs ago. Economy went bad again so I got my cdl. Enjoy what you do 👍
I'm taking my CDL knowledge test next week.
Haha, just pipe that fresh water to us out here in SoCal. 🤣 Nicely done, sir! 👍👍
I know! You guys need it. Same in Colorado.
Plenty of water in SoCal. Tell your govt officials to open up the canals
Every crew needs a Corey. 💪😎.
Yes for sure. I love working with Country Corey!
Well done. I would be very happy with that kind of work and work ethics...
Thank you! Thanks for watching - Shawn
Really enjoying your videos, like seeing contractors with proper well maintained equipment to perform the job in a professional timely manner. Your crew also seems to be switched on and work well together. I worked for a company about 20 years ago doing water mains and concrete storm drain pipe. The machines were in such disrepair it seemed like something broke every hour. Stay safe, cheers from your new subscriber in L.B.I. N.J.
Thank you! Thanks for watching - Shawn
Terrific video again Shawn. You know your stuff. Most drainage videos are bunk.
Thank you Alan! Thanks for watching!
Best drainage videos I’ve seen. PVC is the best! I converted all my old corrugated french drains and yard drains to SDR35 (PVC). It works much better! Also, I love seeing the drains in action at the end of your videos. Great work, sir!
Thank you Matthew! Thanks for watching! - Shawn
Nice one. Well done.
Thanks Mark! Thanks for watching!
Gotta love that slope!
👍
I might suggest that you scrape the outlets with a sharp blade so as not to leave a burred edge- a clean edge looks more finished and professional--JCB-just an idea, it’s nice to see a conscientious contractor overseeing his handiwork
Good suggestion!
Scrape or hit it with torch to smooth & de-burr it.
There's an interesting illusion towards the end. It looks like the one pipe that caught a handful of gutters is flowing a lot more water than the one that is catching the entire back side of the building.... But the one on the back is a 6" pipe, vs 4". It's interesting how the pipe looks the same on camera.
Good point!
It looks to be a fine job but did you manage to avoid covering the damp course on the back wall of the premises, where the soil was graded?
👍
Your work looks good few issues here and there .
Let me know. I may not have explained things well enough.
Shawn, I just found your channel and really like your vlogs. You’ve got a new subscriber for sure. I appreciate the filming and narrative. I also like when you revisit a job site when it’s raining to show that your fix is working. Would it be possible to catch the outflow and work out the flow rate (litres/min) please? Thank you.
Thanks for watching Dylan!
You got one tuff crew bro.....
I know, they are awesome!
awesome video!!
Thank you! I have a video coming out tonight where I revisit this site 251 days later.
It’s amazing that so many buildings are constructed with no consideration of water damage and where the water will go from guttering etc. Have builders and architects heard of a thing called precipitation?
Been watching a few of your videos and like you attention to deals and quality of work. One thing that I think would help with quality is investing in a Sod Cutter. I think if you cut and roll up the sod in the places you are going to drive over and spots that you are going to trench, then once the job is completed, unroll and replace the sod instead of setting new seed, you would have an much better final product.
Nice advice Rob! I did buy a sod cutter and added a 24" blade onto it. I offered it to lots of customers just like you said, but no one ever cared about the sod being replaced instead of seed. I sold the sod cutter since I never used it once.
@@GCFD definitely makes sense. I figured there was a reason behind it as I can see you attention to detail and taking the extra steps to make it right is on point.
Great advice. We have been wondering about getting a sod cutter. I think I will have to do lots of country club work before it would pay for itself. Most jobs folks just want the seed and straw and keep moving.
You could have stayed shallow the entire way "provided" your sealed pipes extended all the way to the gutter itself. The water would have flowed just fine thanks to gravity.
10/10, 6in smooth-wall only needs .49% slope to self-clean so your 1/4-bubble(~2% slope) is plenty. You probably didn't need the extra inch but on my DIY-setup I regret not using eccentric-reducers, as the deeper-discharge would have increased my CB's discharge-rate.
Thanks Bob! That 6" kicked our butts on both the straight sections and also on the angles. Had to re-trench and re-trench. Then we hit a rock.
Yeah 6” is a bear to work with but can self clean at less slope which is nice.
Watching these videos keeps me wondering if building constructors disobey rules for rainwater disposal or if there simply are none in the US - and also that the water is led to the street making it somebody else' problem.
Here in Denmark, if you make a construction with a roof you have to lead the water either to the rainwater sour system or to a fascine on your own ground - never out to the street.
Hi Jesper - Keep in mind you're seeing the worse problems on my channel. The streets are all part of the stormwater management system so we use them as such.
@@GCFD Thank you for replying. If the streets drains are already prepared for the water from all the houses, then in makes perfect sense what you are doing. Thanks for clearing that for me.
Riprap should go at the end of the pipe in the channel to slow water and disperse it over a wider area so it won’t wash out
👍
So many places where the gutters dump on the ground we don't do that anywhere in Australia.
Everyone does it here. The thing is 99% of those don't cause problems. You're seeing the worst cases on my channel because I specifically do drainage work.
You might fine using slow set gray glue makes it easier pushing six inch and larger pipe together
Good tip! Thanks for watching - Shawn
Great advice. I will look into this.
Cory cracks me up. Has he learned Spanish from the other workers??
Who knows! Lol
Great job!
So I've got a question, I've seen other guys pipe the gutters into a French drain, won't the gutter water just go through the holes in the French drain?
Seems like gutters shouldn't be tied into a French drain?
Great question! You never, ever, ever want to take water that's already contained in a pipe and send it into a french drain (pipe with holes in it). I see this all the time and a confusion that a french drain is a *place* to send water to. A FD is a collection system for non-point water. If I catch gutters and run then in a FD's trench, I always keep the gutter water in a solid pipe, separate from the FD perforated pipe.
You should use a laser level when digging long trenches works a treat
I've thought about it but I still prefer placing a level on every segment of pipe to make sure it's falling. 👍
You should get one of those jack hammer attachments for your excavator sometime when you run into something like that rock.
Ah! I've been looking and looking!
You know you hired good people when you have to tell them it’s quitting time 😂
Haha yep! They work hard and I try to make it worth their effort.
Imagine catching all that rainwater into a collection tank, for re-use
It would be a ton of water for sure.
you must be from a desert area. all that water goes to a collection tank, the ocean, then it gets recycled, in to clouds, and delivered, as rainwater. exactly how do you think we can improve on that system?
Shawn, much of what you're having to do should have been done when the building was built. However thankfully for you it wasn't because it gave you and your crew some money for groceries and fuel. Great Job You Guys 👍
This was a tough project. Long runs with little fall, and working with 6" pipe!
Curious why you didn't use corrugated pipe along the side of the building to pick up any water from the foundation as well as from the gutters?
There wasn’t an excess of surface water there since we established a grade away from the foundation so any pipe would not be needed.
Do you use solid pvc pipe or do you use the foam core pipe? The foam core pipe is two thirds the price but it is not as strong.
We use foam core non-pressure schedule 40.
Should of seen if you could put a french drain along that bottom part at the end of video help the water flow
We thought about it but by the bottom the water wasn't harming anything. Great comment!
What state is this in? We have water issues too, but our problem is that we don't get enough!
We're in NC!
Great job on catching and directing the water. Only problem I see is those piles of rocks at the end of the drains gonna make it a bitch for the lawn mower guys. Maybe in the future you can work on applying some type of popup end caps that the mowers can drive over instead of using a pile rocks. Just saying. :) Thanks for the Vids
Great point James. I like my pipes to end up in the air so any debris will easily flow out of them. I prioritize function and less maintenance of the drainage system over other things, though the rocks will be a hassle to mow around.
If you been watching some of Shawn's videos you will know why pop up caps are a bad idea .. they look great, but greatly restrict water flow and having water sitting in a pipe will cause failure down the road even in PVC I would imagine.
Do you drop a tracer wire in with your drainage lines?
I do if the customer wants me to. We use 14/2 outdoor rated romex or just a bare copper wire. We duct tape it along the pipe ad leave it sticking out at a cleanout.
you would save redigging with the purchase of a good dual slope laser.
I've been trying to figure out how to make that work for me. I need to find a mount that will attach to the trencher and stay vertical as the boom pivots down deeper. Still trying to make that work.
We call them downspouts not gutters. The gutters are on the roof.. DOWNSPOUTS!! LOL
We call them gutters or downspouts...short for gutter downspout.
all that high tech camera equipment and you dont have a laser for grade? or eve an old school transit?
First of all , love the vids.
With that said , I cannot believe it’s not a code to plumb downpipes to stormwater in the states , or at least your state
Seems like half your vids are about tackling this simple problem that could have been avoided at construction
That would create way too much surface water if they were all plumbed to the creeks. Keep in mind you're seeing the worst cases on my channel since I specialize in this type of work. 👍
@@GCFD we don’t seem to have the same problems in Australia where all our down pipes are plumbed in ,
It’s all very interesting to me 👍🏼
Keep it up
@@matts490 It's because everything is going backwards down there. Put another shrimp on the barbie, mate!
How has this site faired since completion? Has the low spot in back dryed out some? What about the soil near the building...How's the courtyard doing? They still ok with the discharge lines landing at those parking bumpers? just wondering as I watch this for the umpteenth time..
I am making a video where I revisit a bunch of my jobs and I will head over there and check things out.
@@GCFD I was hoping you’d do that one of these days. But I totally understood that you have to balance work with UA-cam filming.
You don’t have underground irrigation systems to worry about around there?
Occasionally we do run into sprinkler systems but not often. We get enough rain around here that irrigating is somewhat redundant.
Do you set the fall with the trencher or with stones
With the trencher or hand trenching.
What's feeding the cement culvert 31:23, do you know, that's a ton of water, looks like it might be going underneath the property ?
I think there is an inside courtyard as well.
@@GCFD Right that makes sense for a building that size.
I could be wrong... But isn't the rip rap generally supposed to go UNDER the outlet of the pipe..? Isn't it supposed to help hold the soil in place where the water hits it..? I mean obviously you can put some on top too to help hold the pipe down... But I thought the whole point of it was to give the water a place to land that isn't just soil. That way it can't just wash it all away...
Yes you often see rip rap under the outfall. Here we buried a paver under the pipe so any debris won't get caught in it. Great comment!
Kuntry "Corey" to the rescue. Ha Ha. That was funny as hell.
Yep! I love working with Corey.
Haha best part😂
I’ve watched a bunch of your videos by now, and haven’t seen you do any perimeter/footer drains. Any reason for not doing that?
Yes Kyle - I would never, ever, ever send surface water into the footer. Around here we have clay, so the water doesn't percolate down through the soil very quickly. In this case, we had surface water that was hanging against the foundation, so our solution kept the surface water as surface water and moved it away from the foundation. If you have sandy soils then a footer drain might work better, but not in our area.
@@GCFD Aha! thanks for getting back to me, I have clay soil here in NJ. Besides re-directing water I also wanted to re-waterproof my blocks so I figured I would install french drains while I had it dug out.
Sounds like, I re-waterproof, back fill, tamp it down and than dig a trench a couple feet away from foundation. Separate pipes for gutter vs perforated schedule 40. That is how you would do it? Thanks!
And If so, that would also make getting it daylight easier too.
I watch many of your videos and I have to ask one question; why do you always use the straw on top of the dirt? It doesn't look very nice but I am guessing it fills some important function but I don't understand why?
Hi Leif - The straw protects the bare soil from raindrop splash, it protects the grass seed from birds, it holds moisture, and releases nutrients as it decomposes for the grass seedlings. We cover all disturbed soil with seed and straw.
@@GCFD Thanks, that makes perfect sense.
11:47 I notice when you're gluing the 4" white PVC, you only use 1 chemical but when gluing the 6" grey pipe (PVC?), you use 2 different chemicals, what are they?
It should be primer+ glue for both.
@@GCFD So why do I see so many times your people only have the one can of glue with the 4" pipe?
You’re putting the slip joint piping in backwards FYI.
👍 It welds together so it doesn't matter in this case. If we were using non-welded joints we place the bell facing uphill.
Tha "Rock" at 9:50 look more like concreat it a straign 90 cornor and got the same color as concreat
👍
8:15 Wouldn't it have been faster to trench with the chainsaw trencher to dig the bulk of the trench and then widen it where needed with the mini-excavator?
It's possible. Either way should work! Great comment!
That looks expensive. The reality is, it should have been done that way from the time it was built.
I agree. A few foresighted changes could have negated these problems from the start.
That’s why all down pipes in uk are taken 5 metres away from the buildings and into soakaways.
Here 99% of gutters are not a problem. But if you are having problems taking that gutter water away can be a major help.
the bell is not supposed to always be up at high point and start at the run at the lowest point ???
I'm not quite following your question. In push together pipe the bell faces uphill, in Glue together it doesn't matter.
So many of your water disposal end points would be a bad idea in a Northern climate. (I have to stop a comment, frequently, and remember in the South water freezing is a non issue)
That’s an excellent point for consideration. Will that water freeze and become a hazard?
You need to get a better flashlight! Brush hog or bush hog?
Yea I had the wrong flashlight on that visit! It's called a brush hog. Mows down brush...
@@GCFD I have always heard it called a bush hog here in Kentucky. Regional differences in language is always interesting. Great job with the drainage fix as always!
Yea...it says bush hog on the side but it's called brush hog. At least in Upstate NY. (;
Thanks for watching Steve!
All those downspouts and not a single cleanout. Ouch
As long as the water goes away who cares if the building falls apart lol
around 5:00 you're concerned with fall but a sealed pipe that fills a little doesn't matter
I disagree. If the pipe has no fall, the water that holds represents back pressure that takes away from the flow. Flow is extremely important because the faster water moves the larger particle it can carry in suspension.
@@GCFD it may slow flow a little but think of the high spot like a dam wall. Once the dam is full it flows over the high spot. This principle is used to fill water tanks with rainwater when the pipes are underground here in Australia.
@@JyveKilla I hear ya. Dams also fill with sediment when the water slows and drops its load of suspended particles. Better to preserve flow.
@@GCFD if you're draining ground water I agree but off a roof it'll flush through being mostly clean. I would aim for fall but wouldn't be bothered with a slight hump.
Setup a test and see how much difference it doesn't matter
Shawn you’re right with the continuous fall. No humps or dips. Roof granules, dust, (several weeks of no rain builds up dust in the gutters then the first rain washes this dust into our pipe) and leaf debris add up fast in any low spot in a subterranean drainage system. Then this will clog. Then the property owner is wondering why he paid me to build a system that wouldn’t self clean. The humps and dips in flex pipe is part of why they clog.
Who would put a building together like that , they must have know there was going to be a drainage problem
Good question!
Your bell is backwards
That doesn't matter when things are primer+glued together.
Who did consult before degrading integrity of foundation, or are you structural engineer?
They hired an inspection by an engineer for this building. I am not an engineer; I'm a biologist.
Follow-up footage: ua-cam.com/video/kjAvepe0DS0/v-deo.html That's a lot of water!
9:59 looks more like a concrete dump to me...
Hahah Cory had a heck of a time with that rock.
Another builder fail and Gate City to the rescue
👍
Nice pipes, it would be a shame if someone emptied a polyurethane can inside of them.
Yes for sure. They would have to really try to get anything into a closed system like this.
The way to fix this is not a conduit to the parking lot - but to bring up to grade where the the land dips all around the foundation wall - which is apparent all the way around the building. It looks like when the foundation was back-filled it was not tamped down properly - so now it has sagged and sits under the level of the high point of the landscaping (which the sidewalk is sitting on). By simply adding soil all around the building the water from the drain pipes will sheet across the sidewalk and across the landscaping away from the building.
EDIT: Top the berm and push it against the foundation; seed and straw; done.
Hi Michael - we did top the berm and push it against the foundation. that was for rainfall. But there way way too much water coming off the roof that was discharging in the yard with nowhere to go. We gave that water a path out of there where it is no longer a problem. Thanks for watching!
@@GCFD Really appreciate your follow-ups in the rain - makes the job video feel complete!
Documenting yourself jackhammering a foundation footer on video could eventually come back to haunt you, just sayin. Unless you first got permission from the owner - in writing or filmed/recorded to prove it in court.
That footer is none the worse for being clearances a little. Especially given their is no weight bearing on the top of it there.
The foundation overall however is much better off without the erosion.
Like Caffine said above. That was extra concrete from the footer away from the foundation. The water was what was causing the foundation to deteriorate so the property manager chose to address the water.
@@GCFD Ahhh, my bad. I was thinking you were chipping away a piece of the footer itself. Now it all makes sense. ;)
Where's that guys safety glasses chipping that concrete?
Good question. I usually can get them to wear PPE saying, it's for the camera.
Worry about yourself. People like you are ruining UA-cam.
@@mitchjones2821 I was just pointing out the lack of his safety glasses which would help keep flying stuff out of his eyes which would not only cause blindes, it would most likely be painful.
@@matthewrogers94mr right, and YOUR KIND RUIN YOU TUBE.
Everybody knows you should wear safety glasses, ear plugs or muffs, chainsaw chaps, helmets and condoms! It’s a simple fact of life. People like yourself all over the internet think they’re are intellectually superior by pointing out this disregard it is getting old.
