It's always worth putting an inspection point or two somewhere along the the drainage line. That way if the drainage line blocks up with debris one day (which they generally do eventually). You have easy access to put a jetter in the line to clean it out without having to dig or cut into the line.
As soon as I saw the pvc connector i knew it was the price factor! Novacoil connectores are 50 dollars (placemakers) so great way to keep the cost down. Tidy work from you guys too, true professionals
Hey Scott, I watch your videos a while now and few days ago decided to watch from beginning. It is so amazing how diverse you building skills are!!! I am sure that you spend much planning time, what is not seen on the videos. The accuracy is so impressing. I always wished I where a handcrafter like you or my brother, but I am more a desk worker and meeting hopper. In my field I also gathered many different skills in various industries and jobs. Like you said several videos before, don’t stay in your comfort zone, always challenge yourself. I am surprised how similar our mindset seems to be, even we do totally different things. I am only renovating my house privately and it is like an anchor of satisfaction to my work, since I am doing transformation projects for a big company, where results are seen in years later. But with my small kids now those renovation projects are less possible, so I enjoy watching you doing those things. Watching your videos and listening to unexcited and calm way of how to do things, talk and deal with stress is just calming and inspiring me.
I guess an advantage of this job already having a decaying retaining wall was it made it easier to sell the work needed on the new one to make to better this time. A lot of customers don't want to pay for things they can't see or don't understand the benefit of.
but why replace already rotted material with another one of the same composition? The problem with the original was that it was wood. The problem with this one is that it is also wood! If they did it right with concrete retaining wall block it would have been much simpler and last forever.
Holy crapoly. The amount of digging, trucking, pole depth, concrete pumping, dpm PLUS coreflute, geotech and drainage that must have been a 20grand retaining wall!
it is indeed overkill with polyethylene and "Protector". Also and the geotextile does not need to cover the timber side. it only need to separate the scoria from dirt and mud on the side and top
110 drain flo will slot into 100 PVC joiners with enough pushing. 65 drain flo slots into 65mm Marley pipe (not the joiners, the pipe itself!) also with some pushing. Add Marley cement and some tape for good measure and it’s good to go!
@@MrJFoster1984 So do you think you don't need to glue pipes either? There buried in dirt, they'll never move aye? I've seen plenty of pipes come apart underground.
@@cameronrolston6099 pvcs different tho bro cause I dosnt flex as easy as novaflow/coil/nexas I'm not saying it's gonna come apart but the nova fitttings don't come off very easy! they have little locking tabs! trying to trace nova coil in a diggers not the go!as I'm sure you would know bro haha not fun times!!
I really like a crafts-man that are as thorough as you are. I think that today it is far to many people that only go for price and not quality. Love your videos :-) All the best from Norway.
Nice tidy workmanship, on the edge of what's legal for a non- engineered landscaping wall. (As soon as you've got slopes above, below or a surcharge on the wall, or it's over 1.5m high, it needs to be engineered.) The dpm and polystyrene is a concrete wall detail, and really isn't good on a wall like this. With that much scoria, no water pressure will exist behind the wall unless the pipe blocks. With no dpm, the wall will let you know if the drainage fails, with dpm, water ends up trapped in the worst possible place. The filter sock you can put over novacoil adds another line of defence against the topsoil that will wash through the scoria once an avid gardener rips the geotextile. A thin layer of clay under the topsoil will keep the garden growing, in summer, this wall will require lots of irrigation, which will all just end up following out the bottom like South island dairy farms... Also a clay cap can divert storm flows over the wall, keeping water out of the backfill. These are just a few best practices that will make a better wall. However the best design with poor workmanship will fail in weeks, and you've got quality workmanship in spades. Finally I'm sure you used square posts to match the style of the other walks on site, but are you aware that round posts are heaps stronger than squares. (Due to the way fibres are positioned in a tree trunk)
That's a good point to make for non-NZ viewers which will be obvious to locals but perhaps not to folks from outside NZ, the reason for the double wall instead of a single higher one is that if you go over 1.5m, or if there's surcharge or extra load like parked cars, you need to go through a building consent process. So you end up with lots of stepped walls, two, three, or even four in a row sometimes.
Unfortunately, a lot of people don’t realise that a wall above actually surcharges the wall below, so there are a lot of illegal terraced walls out there.. another benefit of terracing walls is reducing the fall height, and avoiding the need for handrails
Lots of great points there about desirable water retention in the topsoil. But a wall won't add surcharge to a wall below if the distance between the walls is at least it's height (45deg angle). unfortunately the error many/most people make with load and the permit requirements is that they determine the height of the walls as the finished (visible) height, not the original or excavated height. Can undertstand the desire to do that tho' - permit and engineering could easily add $10G to an already expensive job like they did here. There was so much scoria in this wall there was almost zero need for the coil except at the exit point. And I don;t know many gardening tools that will easily puncture the double layer of geotech fabric!
There shouldn’t be not one 👎🏾 down . Who don’t like sbc his content is great he’s a very likable person , him and Paraeu are some cool ass dudes. He has made me wanna visit NZ!

Very nice work mates! A good guide for constructing my own retaining wall, which will be timber but using galvanised steel H column as posts, and I then slide lengths of hardwood in between. The polythene and XPS foam on the inside is a good tip, it keeps the timbers dry, the XPS does not only protect the polythene from the sharp corners of the stone, but actually should prevent condensation build up on the inside when ambient air temperature rises above soil temperature. I use Bankirai wood, which is a bit expensive but should withstand the wet climate in the Netherlands well, this wood is used for building shore walls in streams and canals. As I'm going to apply a tar coating on the inside of the wood the PE membrane shouldn't be necessary, but I still can put that XPS in as I have a couple of left over packs after insulating a floor. Also a good tip on using standard PVC fittings to connect to the spiral hose, so I must be sure to buy a size hose compatible with PVC size ie 75, 80 or 100mm. Btw, Auckland is a great city, visited NZ twice and would love to come again.
I like the way you guys use plastic + white foam + the plumbing drain system to protect the wooden wall, but if i was you, i would use the 6” diameter or bigger size plastic pipe , and then pour cement + metal bar inside the pipe, use them as a post, replace those wooden posts, so it won’t get rotten or eating by termites . Anyway, good job you guys
U should use blue metal steel for drainage as well helps water fall straight into your agg instead of sitting dirt that holds moisture sands soils are also good
This is sweet! But I am confused why they fill in behind the wall with soil, cover that with geotextile fabric, and then put more soil on top of that. Doesn't that reduce the depth of your planting bed by a lot?
You've built a wood lagging retaining wall with 2 or 3x8 lagging. The lagging therefore has spaces each plank which is about 8 inches. Won't the water be able to drain out of the wall at the space between the lagging? Are you concerned that the gaps between the lagging will get clogged and prevent drainage?
It's a good job no doubt but the cost would be huge. For a small, very basic retaining wall. For a little extra on top of this massive bill, could have build rock wall instead. Looks ten times better. If cost is not the issue, just about any body can do a great job. But do it on the budget, that's the skill.
You are first guy what is using geofabric on retaining wall. Here in au people don't even know what is that for and what the geofabrick is. Maaan. First wall build proper way like from the book.
there is a kind of dimpled plastic barrier that can go between the drainage material and the wall.There is also a school of thought that says the geotextile fabric itself will eventually get plugged.Does the drainage coil/drain have some form of "inspection point" to enable flushing the drain out/unblocking?.Love the way you describe what you are doing,and the real quality of your work
The only real risk of those points is the coil blocking. I forget the angle required for it to be self clearing but he had it only barely off level. But seriously, with the amount of scoria they had in there they really did not even need the drainage coil at all.
@@DiscoFang Tend to agree with you. I noticed also that the scoria backfill wrapped in geotech was almost to the top of the wall with about 200mm left for topsoil to grow some grass. So its not like there is much of a drainage impediment - no need for plastic imo
I'm seeing elsewhere that PVC is not recommended for the back of a retaining wall, wood in particular, as you're creating a dam that is an impediment to water drainage generally. Geotech fabric only, according to some. I'm no expert and in two minds as I had considered PVC to force any ingress down towards the drain pipe.
Wow the amount of work that went into that wall must of cost the customer a absolute fortune or you made nothing from it (looks like a job from hell) excellent job thought 👌
Hi Scotty, it looks like you've added some sort of tie backs @5:46. Any details? I'm revisiting some old videos as I've got a few retaining walls to construct.
As soon as I saw 6x6 timbers as posts for a retaining wall I knew it was outside North America. Very curious as to long term performance on these walls, rainfall amounts (average per year, median per event, etc.), soil properties, etc.
It seems is a bit cold over there isn't ? Here in Brazil is damn cold too that season of year ,i mean winter time ,some times get 4 degree below zero Great job, guy and hello from belohorizonte city Brazil.
How much weight would this method of retaining wall take? I need to build a retaining wall in my garden but want to build a brick BBQ on the top layer....
great video! A question: In a densely constructed residential area, if the lowest point in the retaining wall of your "elevated slab house" is at the fence you share with your back neighbour, what will you outlet of the drainage be?
Nice job! But I think you missed to protect the other side of the wood structure(underground)!!! I didn’t see your parts 1 and 2 of video and I hope the lumber you were using is treated with something, but it won’t last long... concrete would be much better choice imo...
For retaining walls timber is pressure treated to H5 hazard level meaning it will not rot when underground. Hopefully the nails used were stainless steel. The plastic was just there to reduce any resistance to water draining down to the pipe and avoid built up water pressure behind the wall which is the No 1 reason why most fail.

Insanity, no other work on..
Scotty and Master P. Job well done boys.
it is indeed overkill with polyethylene and "Protector". Also and the geotextile does not need to cover the timber side. it only need to separate the scoria from dirt and mud on the side and top
That little dog sat on the digger made my day! Thanks SB. Great video as always
Nice work mate! I don't think it's overkill. It's how it should be. Diverting the water is probably the most important thing in the wall.
110 drain flo will slot into 100 PVC joiners with enough pushing. 65 drain flo slots into 65mm Marley pipe (not the joiners, the pipe itself!) also with some pushing. Add Marley cement and some tape for good measure and it’s good to go!
Great job Scott Brown. This is the only tutorial I could find online, nice and detailed
When doing drainage I chuck a couple of tek screws in the pvc joints to hold shit together. I wouldn't trust just tape.
Tools & Stuff Hows it going to move with the stone on it?
@@MrJFoster1984 So do you think you don't need to glue pipes either? There buried in dirt, they'll never move aye? I've seen plenty of pipes come apart underground.

Well done lads, that was no easy task. Love the little Jack.
Another nice looking well thought out job. Nice work Scott
A lot of work for a retaining wall, would you not be quicker with a preformed concrete wall with the land drain and clean stone behind it?
A timber replaced with another timber. For how long will it last?
Would the topmost retaining wall be benefited by a deadman anchor? If so, what kind of a deadman anchor would you add in it?
I'll tell you what... this is a job well done! Above and beyond what's expected, I'd say! Nice work!
Hey SBC did u need a permit for that wall or because it's stepped does that takes away the permit issue?
I was wondering why the second/bottom wall was needed, since it appears the top one goes deep enough to take all the necessary load.
Great video, really enjoying your honest videos.
Just as a question, how much time does setting up shots and talking to the camera add to a job?
Wow the amount of work that went into that wall must of cost the customer a absolute fortune or you made nothing from it (looks like a job from hell) excellent job thought 👌
@Oxdard Oxdard You clearly know a big fat zero about timber treatment.

Tons of these in North America too...
always good to see Gaston, the tools Santa
Very high quality Scott nice
Where does the drainage eventually go and connect to, or just into the grass at a lower point?
What Guage or thickness is the black polyethelne that you use to protect the timber?

Or a layer on top also?

How many dogs did the driver go through until he figured out how to train them to stay on the digger?
Jack Russells take about 2 seconds of training for pretty much anything.

Whats the life expectancy? Would rot out in 10-12 years here in ireland I reckon unless you made it out of green oak at a cost of $$$$$

What’s the black paint or stain you used on the wall?
Did anyone notice the dog having the time of his life on the digger :)
Another awesome job done well! Congrats! Love your channel bro!
Hi Scott. How long do u think the drainage system will last for ??
