here's the daily compliment on how wonderful and informative the vids are! and super great for all the viewers that never seen this method.

Great video Robin, and wonderful sentiment about wishing you could respond to all of your commenters. Looking forward to seeing this project progres😎

Great video Robin! Found it very interesting indeed. Cheers.

Excellent video mate 👍

Love how the car issue holding up the work was left in. Everything and anything happens on a site regardless of all your planning! Handled with class too

Always love a good “pull test”

Definitely need a detailed video this time on the ring beam attaching to the ground screws and the plastic ply :)

Love this channel keep it up

So interesting love the content

I hope we see you build this one from start to finish too!

Very interesting thanks Boss

More garden rooms. In my day we were lucky to have a shed and before that an Anderson shelter. Those little screw piles are brilliant for these type of buildings of limited weight. We get an even smaller version that you can use for ground level decks but haven't seen the sort you keep using. Got to be better than keep digging holes and concrete.

12 under our 3m x 4.3m studio, about £950 from memory. Took about 3 hours but, when we came to start the build (SIP) it was running out by 13mm. Had to get them back, quickly resolved. Not much forgiveness with a SIP build but massive difference in U value compared to stick built.

Interesting measurement techniques. Does (lateral) wind load play into your calculation? Thanks for the video.

I’ve been doing ‘pull tests’ for years!

Robin can you do a detailed in depth garden room build series?

Robin, I’ve been thinking about using these and I’ve seen they sell a hand screw attachment for manual screwing? Do you know if this is actually viable for an average garden or is it just for a garden with 6ft of topsoil

If you need more bearing surface area after the screw is driven, you could remove some soil around the surface level of the screw, add rock and compact it, and then pour a circle or square that would bond to the exposed screw threads.

If you're willing to pour concrete pads around the screws, the screws are redundant. The whole point of them is fast installation and low impact if you decide to remove them in the future.

Hi Robin, tell to your colleague that better to twist off an extension cord during the and use protection garniture)

Will you be the construction of this garden rooms in follow up videos to come Robin?

How much torque does the driver put out? I would’ve holding my breath every pile hoping not to hit a big rock 🪨

Nice job! What gearbox ratio do you guys use in this case?

How about to do a push test? Now we all know the wind wont pull it how about the weight of the garden house( large one i mean)?? After some time (winter or lot of rain) will it push it deeper or will it stay the same ??

Does that need planning permission or building regulation approval?

How does pulling the screw out under tension test how much weight the screw can support under compression? Two entirely different forces acting in different directions !

Can these ground screws be used on a house extension? One built using SIP panels like The Hup system.

Don’t forget wind loading on a structure!

👍

So the pull test, assume it sustained 1000kg would you assume that as your total max load so reduce that my by a safety factor?

How does a pull test tell you the downward force per screw.? I like the system, very good for poor access and uneven ground.?

@smitmachinale8281

3 жыл бұрын

Exactly, a pull test is not the same as a push test. A push test would be difficult off course, but it may be that the screws can handle more down force than the pull test reveals.

That couldn’t have been 2 n half tons pulling on that screw? Or was it 250kg? Great video anyway 👍🏼

Hi robin very interesting, but why not a traditional re-in-forced slab foundation, raft or even strip foundation? Surly after you have paid for these guys to come in with their rig and pull test it works out more cost effective?

Hi Jack there is no comparison to the price, I will do an alternative costing for one of the episodes of this build and compare, one thing here also is that the position of the room is about 200m from the road and it is land locked so other than a tiny excavator it would be a hand dig!!

Dont forget the live load like snow

That garden's the size of a football pitch!

Lot if faith to put in a "should be" okay when you're putting in the ground spikes.

After watching one of your earlier videos featuring ground screws I got Gil to come over and install screws (great work! all done in a morning) for a garden self build I started last month. 6x4m pitched roof timber building.. will be following these series closely as I build mine! Keep up the great work! Edit: If you are doing a warm roof on this build and can share any details that would be great! about to embark on that phase of the build now...

So your using this to calculate the weight each screw can take before sinking ? in this video circa 2.5 tonnes each ?

@vidpromjm

Its called a pull test because it measures the amount of force needed to pull the screws out of the ground, ie the uplift from wind specifically during a major storm

Just wondering what exactly a pull test proves ... the building is sitting "on" the screws so I would assume most of the risk is screws somehow sinking when load is added ? might be stupid question 😅

@tlangdon12

3 жыл бұрын

The Pull Test proves the amount of tensile strength in the ground and the screw. If you imagine quite a light building, like a garden shed, in a very high wind, the wind is trying to roll the building over, so there is upwards pull force on the screws on the side of the building closest to the wind. This force can be greater than you think in high winds with slab sided buildings in exposed location and with certain roof shapes.

Robin what is a ballpark cost for the installation of Ground Screws for a Garden Room of this size?

@ukconstruction

The pull test yeilds and means not much. But at least the yeild will be more than the load. On chalk or clay, your probably good. Gonna need a long one on sand and shale. Same shit realy, I like 'em. Piles are piles however you do them.

To do a push test you'd need either a lot of weight that could be concentrated on one pile, or something like an excavator and a really heavy duty set of scales. 😁 Forces should be about the same whether pushing or pulling, as haz said.
