- The Process of Soil Stabilisation
During initial surveys for the construction of a new supermarket distribution centre in Newbridge, Ireland it was found that the ground was insufficient to bear the weight of the building or associated hard surfaces around the building.
There was a layer of peat under the surface that needed to be removed and the rest of the clay-like material wasn't suitable for building on either. The expensive option would have been to remove all the material off-site and then to bring in aggregate to take it's place. Option two involved removing the layer of peat and stabilising the rest the material with cement, which was strong enough to bear the buildings foundations
Newton Ground Engineering which is part of the CAB Group undertook the soil stabilisation contract. The stabilisation was done in sections and layers 380mm deep which compacted to 300mm.
Excavators load the pre-treated soil on to ADT's which transport it over to the working area. Bulldozers then level the soil to 380mm deep using Trimble GPS systems. Spreaders distribute a precise amount of cement on the layer of soil, with Wirtgen WR250 soil stabilisers following after to mix the soil and cement. Bulldozers then level the treated material allowing rollers to compact the layer to 300mm. In the end a sample is taken to be tested.

Excellent VIDEO 👌👍
You've really outdone yourself with this one.
Awesome video! Looked like lime rather than cement? Great job and I wouldn't have minded if was 10- 20 mins long! Haven't done this since 2005 and it is impressive! We did an industrial park with warehouses 250,000 to 1,000,000 SF. All of the pads were done with lime. Semi trailer parking lots and docks were done, with both lime and cement. One we did in the middle of winter in Ohio and the lime made it lime dirt inthe summer! That site was so bad with fall rains and putting in storm and sanitary, that we were just about storm grade! Just like in this video we made controlled lifts of ... I think 28 inches. But we were spreading mud! The hydrated lime could suck up 10x it weight! Then we came back and did the top 2-3 feet with cement for sub base leaving it 2-4 low. The next spring we went in to finish grade the stone base and you could barely cut it with a graders or roller. We actually have the company come back and loosen the the top 4-6 inches. That made me a believer! The company was done the other pads and parking lots so no big deal.
We also did some roads that were jointly maintained by county and state. There were a bunch of raod that went through a flood plain and the lower part of the county. The State got federal money. What was different about this application was we mixed RAP (Recycled Asphalt Pavement) in a 1:! ratio of clay and RAP. Then hit it with lime. We allowed the lime to do its thing. Then came back and hit it again with cement up to asphalt grade. We did 2 to 3 lifts in most places with the top lift... 28" ... or the maximum depth of the reclaimer in cement. (maybe ir was 21"? I know it was right at 2 foot lifts. Regardless, that was done in 2006 and those roads are still rock solide today! It really made me a believer! We did a lot of county and country roads in surrounding countings after that until 2008 when the economy and the construction idustry tanked! Now I do consulting, inspection and test for civil projects!
I'rm really thank you, great work and presentation.
VIDEO WAS AN EPIC ADVENTURE.....I FELT LIKE I WAS THERE DOING THE WORK
Great video of the process. (and good cinematography!). Well done.
YOURE CHANNEL IS AMASSING..I LOVE IT..THANKS
Awesome video! You had some great shots in there. Loved the transitions!

Awesome to see some Wirtgen machines on RUclips since John Deere bought them a couple years back they have all but disappeared from RUclips. Currently waiting on trucks sitting on my Wirtgen W-120 milling machine.
amazing video and camera work
Liked subscribed , really good work , 👏👏
Worderfull camera work!!!
Masterpiece of video editing and drone/camera work 😮 what is mixed through the soil. Portland? Is soil clay content a factor here? Doos it have to meet a certain threshold? How froat hardy is the final surface?
Great stuff, be interested to know what CBR/NDT results were got before and after.
Well done on the video work and editing.
Those wirtgen mixers are pretty fun to run lol used to run it 7 days a week 12 hours a day.
Have you driven one of these? I’m thinking about buying one and wanted to get some feedback from operators?
Brilliant video mate ! - Kieran
WarwickWard Thanks Kieran!
Great video. Machines working well, though the young lad taking the ground sample needs a lesson in using a sledgehammer.
The young lad was stretched out trying to hold a metal sheet of in place with his foot. That was the prblem not bhow hi was using the sledge.the guy standing watching and doing nothing was the problem not the lad.
WITCH DRONE YOU USE? FANTASTIC
Good Afternoon, Thank you for another excellent video!! It looks very time consuming and weather permitting job?? Take care 👍😎🇬🇧.
Wayne Compton There isn’t much in the earthmoving business that weather isn’t a factor in, except maybe rock/quarry work. Thanks for watching a commenting.
Good video. Just a doubt, what these machine in the thumbnail does ?
Gustavo F. Moreira They mix the soil and cement.
And how much percentage Adding hydred lime???
The white powder is calcium carbonate?
Fantastic camera work!!! 😍Best construction video I’ve seen in a while..... hard to believe liming the ground can make it so strong😃 is this job in Ireland...... if so where
Jason Collins The location is Newbridge, Ireland. The material is so strong after stabilisation that the foundation piers of the warehouse can go directly on to it rather than having to pile through it. It’s far harder than any natural ground excluding something like granite rock.
Awesome Earthmovers ya looks pretty tough Harte after the rollers and the fellas doing the test there but do they have to do many levels of it especially if the need to get to a certain level/height? going to be some size of a storage unit....... Factory?
Jason Collins It’s actually far from its final hardness after the rollers have been over it. It takes days or weeks to fully harden, and when it does it’s like digging rock. They have to do it in layers of 300mm until it’s at the desired level.
These are the machines spoken of the prophets thousands of years ago.
I need to do this to my yard cause of all the moles.
U musta been runnin ro7nd there like blue arse fly lol ! , when’s do we see the official C.A.B advert !? 😉
allistairc123 Been waiting since April for them to come back to me with ten captions to describe the work process.
😮
Please define who much cbr coming.
the white truck is a strange one
Ducking top soil damn
Good video. Could do without the music
nice machines, and nice video, but where the fuck is the water.... its way way to dry, this way its nearly useless work
и для чего они это делают?
Whos this contractor think i know some of the drivers 🤔🤣
50% lime 50% cement @ say 14kgs square meter or 30 lbs per square yard in your guys language?
So this mix of lime and cement assists stabilisation? How long has this technique been around?
@@kneewall49 Wirtgen intoduced the first WR2500 in 1995
Looks like this is what has to be done when all the earth worms and natural bacteria have been killed off in a soil, what is the end use for this, genetically modified foods?
i'm quite sure this project has nothing to do with any of that.
the ground was made up of stuff that wouldn't make a good foundation, this project seems to be using as much of what was already on site by digging it up and mixing it with other stuff to make a good foundation.
all of this is guess work on my part mostly form reading the description.
Ребят, чё происходит здесь??
Готовят фундамент для здания наверно, кидают известь и цемент на землю, а эти машины все это смешивают ну и прикатка напоследок
A bit too much " EPIC " .
Not the best hoe operator loading trucks. I dont care if the top of a truck had a go pro on it. The first truck was missing 1or 2 buckets close to cab where it counts
Luther Blankenship They are deliberately not filling the trucks up. The area that they are taking it to is being stabilized and cannot be damaged or chewed up too much by the trucks.
@@AwesomeEarthmovers ok. Well. As much iron as you got there you have to maintain a haul road. Less dirt is less money. People make profit off the scoops left out like on your video. That's the purpose of on site Rock trucks. I do dirt work every day. The name of the game is move as much as dirt as fast as possible time is money. money is time
Luther Blankenship You need to understand that the focus of this project is soil stabilisation. They have to treat a certain sized area in a day 1 foot deep. They can’t do any more or less. It makes no difference if they load those trucks as full as they can. The same amount of work gets done in a day. One layer has to harden before another one can go on.
@@LUTHERJ304 pick up your broom and get back to moving dirt you know nothing laborer.
@@asherdie is that what your boss tells you
