How do you overcome frost heave?
Install so the bearing fins are blow the frost line
Where to buy in Canada?
Rona has them.
Hello, I've just installed a sample 1.2m in garden. Is there some way of knowing what load it can take once installed. How easy is too easy to turn?
Yes, the load can be calculated from the final installation torque by multiplying the torque with pile´s kt-value which is defined by the diameter of the pile tube (with 60.3mm pile kt-value is 33,5). The result you get is in (N), so to convert that to kN you need to divide the result with / 1000. For example: if you rotate the pile with 1,5m lever and 20kg force you will get 294 Nm torque x kt-value (33,5) = 9 849 N = approx. 10kN = approx. 1 000 kg per pile (without safety factor). ´Too easy to turn´ is if you have for example 1,5m lever and you only need to use approx. 10kg or less force to rotate the pile. In that case using the extension pile is recommended.
Is there any place in the USA to buy these?
These will be available soon in Canada and also in Amazon US
@@PAALUPISTESCREWPILES This comment is a bit old... any update? I'd love to order a bunch for fencing and a deck!!!
Are these available in New Zealand?
When will they be available in the USA?
Apparently never. If they pat off politicians here in thr states it might happen.
@@wadebrewer7212 something similar is available from Home Depot and these have a 100+ year history behind them. in all sorts of construction I can't believe I just found out about them yesterday.
Hmm. How do you ensure that you install the screw pile so that it’s level?
On some you can drive a piece of rebar in first to ensure the pile is straight otherwise you got to use a torpedo level at lease for the first few feet I imagine
can these extended 3 to 5 feet above ground? I live near the ocean
No. Sorry.
How much weight can these hold? I am looking for a way to add onto my garage without killing the tree (roots) that sits right outside on where the addition would end.
See 1:53 but I think you'll need to know your approx. soil shear strength.. Apparently, one way to test it is to measure the torque required to drive in the pile but presumable that only works if your using a power head. You could try the UK agent.. UK Helix (other companies are available..!)
We have helical piles up to 800 kN loads, but these DIY-piles presented in video are commonly used in cases where individual pile loads are max. 30kN (approx. 3 000 kg) per pile. There are certain limitations like pile buckling that needs also be considered, but for example normal garage loads are not a problem for our DIY-screw piles.
CAREFUL BUYING THIS...You can NEVER assume soil bearing capacity. I've been installing helical piers for 10 years. The whole point of a proper installed helical pier is that the installation equipment has a pressure gauge that translates PSI -TORQUE- COMPRESSION in pounds. Essentially the machine is measuring the soil bearing capacity has its being installed. This way you KNOW that it will not sink, settle, move. Each pier is installed to meet the called out structure load in compression AND tension. If you are using helical piers use a company that has been tested extensively and can provide an engineering report to you after installation.
It is not that difficult to estimate screw pile capacity for DIYs.
Qu=Kt x T
Qu=ultimate pile capacity (lb)
Kt=empirical torque correlation factor(/ft)
T=final installation torque (ft-lb)
ICC-ES AC358 default Kt values
1.5 to 1.75 inch solid square shaft: Kt=10/ft
2.875 inch diameter round shaft: Kt=9/ft
3 inch diameter round shaft: Kt=8/ft
3.5 inch diameter round shaft: Kt=7/ft
T=FxA
A=length of lever arm(ft)
F=force applied at end of lever arm normal to the arm(lb). Measured with a large fish scale
Qa=Qu/2 (Allowable pile capacity with a safety factor of 2)
@@davidfranklin5270 Are you crazy, or a company employee? Most people don't have a clue as to what their push/pull is in newtons. I'm interesting in the company's products, however they need to have some sort of gauge each person attaches to the pole end and themselves to give some sort of measurement from which to compute. Otherwise this would be fine for a small garden shed, but I wouldn't put my family and friends well being to the test with something like a deck or garage as previously inquired.
I'm looking into it just for a shed. Anything else is nuts.,
@@boots7859I think the problems have been worked out sufficiently.
From Wikipedia: Screw piles were first described by the Irish civil engineer Alexander Mitchell in a paper in Civil Engineer and Architect's Journal in 1848; however, helical piles had been used for almost a decade by this point.[2] Screw foundations first appeared in the 1800s as pile foundations for lighthouses,[3] and were extensively used for piers in harbours. Between the 1850s through 1890s, more than 100 screw-pile lighthouses were erected on the east coast of the United States using screw piles. en.wikipedia.org/wiki/Screw_piles
Whats your plan when you hit rocks?
Thats a great question. Maybe you would drill into the rock and fix a different type of pile with concrete to the rock?
This is depends a lot of the structure and what is the frost level in the building area. There are few ways to overcome the stones: 1) If the structure allows you move the pile, you can always unscrew the pile and move it slightly different place 2) If the structure does not allow you to change the place, but the pile is already deep enough concerning lateral support and frost level, you can simply cut the pile in the level. 3) If the structure does not allow you to change the place, and the pile is not deep enough yet concerning lateral support and frost level, you need to remove the rock or cut the pile in the level + make the additional frost protection around the pile (styrofoam ect.) 4) By installing with machine the piles are easier to install coarse soils.
