River Gabion Installation Part 2 - the main baskets
Вставка

- Installing the main gabion baskets on top of the gabion mattress from part 1 ( • River gabion installat... ). This video shows the preparation of the baskets, filling the baskets with granite gabion stone and back-filling behind the baskets with stone from the river. Finishing this job with fencing and path reinstatement has been delayed by other, more pressing jobs, so part 3 is also delayed.
NB. This is definitely not a 'how to' video, in fact it might be the opposite.
Actually very interesting vid on how to repair river erosion . I’d love a job like that , you’d be able to stand back after a phookload of hard work and actually see that you’d made a difference. Respect to you sir 👍🏴
Great Job.Thanks.
Wenn I See you carring the stones, my back hurt.

My back's still hurting now! Thanks for watching 👍
Pretty interesting. Has a very organic look and feel. Of course you realize many people commenting on your hard work know better than you despite not knowing what a gabion was before watching your vid.
What you said........so true it's funny. Had to smile and snicker!
I helped build gabion rock walls 25 years ago. The wire baskets eventually rusted out and the stone collapsed. It took several years for it to happen, but it did.
Lol exactly! Everyone drinking beer in their computer chair and "supervising"
This is mesmerizing man. What a crap ton of work.
Thanks, I was starting to dream about pushing wheelbarrow loads of stone towards the end of that job!
For that application, and as much work as you put into it, I would have recommended Beaver Dam Analogs as the cheaper and faster solution. Plus, you get the benefit of slowing the water when it comes down into the pond rather than speeding it up now that the channel's narrower. Sediment aggradation behind the beaver dam analog actually replaces what previous storms have removed, building the land back up. Plus, they're a huge boon to the local eco system and water table.
“It’s not a how to video. It might be the opposite” It says so in the description
@@noeraldinkabam Hence why I thought to add an alternate idea. The gabion will protect that side of the bank, but by narrowing the channel with an impervious barrier, it will force the flow to eat way at the other bank. The speed of the water won't be slowed down so erosion will be moved rather than lessened. The good news is that a BDA could still be installed and the gabion achoring that bank so that the storm pulses are smoothed out while soil aggradation helps rebuild what was lost.
Beavers can do great things for the environment.
@@johnbeckwith8313 Love those little guys!
When I'm walking the woods, I'll build little beaver dams along the small folds I find. They might be dry now, but you know they'll have water in them when the rain hits, and every little dam I make will help to slow the runoff a little. 😁
@@threeriversforge1997 beavers make beaver dams. You make man dams.
Spectacular.

I love gabion walls. I have built two decorative ones in my yard.
A suggestion from experience on heavy, rock loaded wheelbarrows: tip straight over the wheel. Otherwise you will torque the axle beyond replacement. Tougher to do after a long day, but necessary to avoid later aggravation. Reduce load if necessary. Great project. Have done a few myself, so I know the transition from bright idea to " need to finish the damn thing!" 💪👍
Thanks for the comment - I hadn't considered damage to the wheelbarrow, but it makes sense that using it that way wouldn't be good for it in the long term. That particular wheelbarrow is looking pretty knackered all round now so I'll have to make sure I take more care of its replacement!
Gabions are one of the best ways to fight erosion and stabilize banks. The sheer mass in a basket means it’s not moving once full and any hydronic pressure from water in the bank is allowed to pass through without pushing the wall. Concrete suffers from that pressure in most cases.
Lots of work!
I have done a smaller gabion project and it was like "endless". I did use some river rocks for the outside layer (just for the looks) and inside I used angular in situ rocks.
Yes, there is a point when you think the baskets will never fill up. Thanks for watching!
Hard working man.
Solid bradda this style of erosion control mahalo for sharing the knowledge and God bless you and your endeavors pau =E KU=
Wow! Great job!
Thanks 👍
Great job that man
Goood job
impressive
Hats off to you, I love doing this stuff. Question though why not a lime cement with high ash content (water setting) poured into the crates? The metal will be gone in 10 years. Also, seems like a prime opportunity for hydro power. Too far away from consumption?
To be honest, I hadn't thought of that. I don't know anything about water setting cement so it didn't cross my mind - it sounds like an interesting idea though and one that I'll consider if I'm ever called upon to do something similar in the future. Thanks for the suggestion.
As far as hydro power goes, my job was specifically to reinstate a path at the top of the river bank, so that would have been outside my scope.
Are the Gabion boxes stainless steel or galvanized?
They're galvanized - the budget wouldn't stretch to the stainless steel ones
Why is this legal or applied in municipal applications but not allowed for property owners?
A nice decorative stone wall but not practical for long term protection. The wire will corrode and fall apart and then there will be a lot of rock strewn everywhere. Some will argue the galvanized wire will last forever but it doesn't.
No matter what that's alot of work
Thanks👍
Should’ve used the same material to backfill the gabion wall, those river rocks gives the surroundings and riverbed character.
Fair point, I should have quoted for 40 tons of stone instead of 20. However, there was so much rock on the riverbed that even the amount I took didn't seem to have an impact (visually, at least).
@@footprintconservation8668 no the rock you used was perfect. The river rock is rounded and is much weaker when building gabions. The angular stone that you used will lock in place and provide strength to the structure to hold it together which is exactly what you need in this case.
You can't use river rock to build Gabion walls. Rock is not created equal. River rock could be used for a decorative Gabion but if your building it for structure you need to use angular rock so they lock together for strength. I work for a road dept and we use Gabion walls to support roads so for us strength is critical. It looked to me like this Gabion was being built to armor the slope and prevent the trail from washing out. If that is the case, you would use angular rocks as well so that they lock together and minimize the water seeping through them.
OMg that's an insane amount of physical labor . I had to take three ibuprofens after watching this video .
I have to agree! Thanks for watching 👍
nice
Thanks!
Bonjour Mr,puis je savoir comment faire ces cage en fil de fer? Merci
Problem with this method of filling (dumping stone in) if that you usually deform the face of the basket. If you don’t care how it looks it’s fine but most people want the baskets to stay square. I always suggest placing stone not dumping but to each their own I just make baskets.
🐜👍🏼
Thanks
I hope you don't want that to stay up permanently. The wire will eventually rust and the stones will collapse. It will last a number of years first, but it will eventually collapse. Nothing can take the place of good old fashioned dry stone walls.
True, a retaining wall built of stone would have been the best option, but very difficult to achieve because of the location and the cost would have exceeded the budget!
@@footprintconservation8668 , that's fair enough. I assumed there was a reason that you chose this over a drystone wall or a mortared stone wall. I hope it lasts many years before it needs any major restoration.
This is really bad for stream function and just moves the issue trying to be resolved (generally natural bank erosion) downstream. Bank erosion in this type of stream system is an inherent and critical part of stram function. What happens is this starts a cycle of "repairs" that end up hardening more and more of the stream, causing more and more loss of function and requiring more and more maintenance. Simple solution that maintains the actual conservation of stream functions is to move the trail.
There's nowhere else for the trail to go, the alternative was temporary/permanent closure.
What is the purpose!
At a guess - reduce potential for the erosion of that pathway on top of that river bank when that stream is in flood.
I wondered the same thing but there appears to be a path at the top with hazard cones. Reducing erosion and chance for path collapse/further damage I suspect is the reason. Kinda wish a couple local ish parks would do something like it instead of just close trails
Spot on - the local authority is responsible for maintenance of public paths so they had to make it safe. There was no room to take the path away from the river bank so the bank had to be built up.
It's gona take 10 years
I strongly think that gabion walls are meant for temporary fix. The netting will fail once rusting occurs and the rocks will collapse.
While you were at it why not just dam it up and make a small pond. 😂😂
Ummm little overkill? lol. Its a creek not the amazon river.
It's true the river doesn't look much most of the time, but it takes a fair volume of water when in spate and the bank needed to be built back up to 6' to reinstate the path.
Ugh, the most hideous streambank stabilization option ever, so many natural alternatives. However, for something like this situation, relatively high banks and shaded, most of the best options require heavy equipment to install, so a manual method like this is an option with no equipment.
Glad you approve
I don't approve, it's absolutely hideous and it extends way too far into the active channel and will end up accelerating streambank erosion on the opposite side.
Ugh, The most hideous keyboard troll ever, so many natural alternatives...
Covers up artifacts and it's ugly.
Your lower back should be studied by doctors around the world to see why, not being a young man, you can do that much of that kind of work.
Galvanized wire in a very wet environment… Yeah… That’s not going to last… You would have been better off with riprap and a planted top fill (which it what that will become, once your cages rust out).
Two things if you are a millionaire you can afford that much money but if you are a millionaire why doing it yourself!! But yeah its a awesome job!!!!!!,comgratulations!!!!!!!!!!,🔴🫢🤫
Ah no, not a millionaire unfortunately - this was a paid job for the local authority. Thanks for watching and commenting.👍
@@footprintconservation8668 hahah !!!yeah !!love your work great talent!!!!a great job !!!,🔴🫢🤫
