Lots of suppliers around if you Google them. The machine itself is around 6k and we buy groundscrews in quantities of 100 so I would say best to get a company to install them.
So last 2 weve built have been close to boundaries. Right next to fence posts full of concrete also hepworth super sleeve drain and tree roots . ? Waste of money cheaper to dig concrete pads or small piles there too expensive .
Will go through tree roots but ground needs to be assessed prior to installing, same as any job. Sometimes concrete is best I do agree! Bloody hard work though.
@@woodbridgegardenrooms when you say assessed what do you mean ? We've looked at using them a few times but every time I just think cost is too much . Regular size room 4x3 what is there 12 screws ? That's about £1500 ,concrete yourself plus digging out £250 plus abit more time depending on ground . For garden rooms of reg size I just think there too expensive now bigger ones maybe we build extensions as well if they can get these through building control then there a winner
@@jharris7407I mean if the ground is assessed to be rocky or lots of tree roots I would look to get a base done. So we put 20 of these in today for a 5x4m garden room. We were done by 11am. It was a 40m walk to the driveway so doing a dig out and concrete pour would have been horrendous in 25degree heat. They will pass regs if you get a pull test done on them and submit. It costs about £500 for this report but if soil is clay then each ground screw is usually good for about a tonne.
@@woodbridgegardenrooms Hi, may i ask why is that pull test is done on these? Isn't carrying capacity more important? Only thing i can see pulling these things is wind force to the building. But weight of the building and snow would force them down not up.
where do you get these from? are these usable for a pro diy'er?

I rented one of the machines for the equivalent of ~160 USD for a day.
I had zero experience and it turned out very well.
@@MisterBlueSkycan’t say I’ve seen any for hire in the UK yet but I haven’t looked too hard.
Can this be used in very sandy soils? We've seen helical piles used here, but they go down 4 meters to get adequate torque spec.
Depends what’s going on them. Our garden rooms weigh between 2 and 8 tonne so just putting more in to spread the load is likely an option.
