I'm a builder in Central Texas, and in this part of the country we have the same concerns with soil movement due to drought conditions as builders in Northern climates do with the freeze-thaw cycle. Building slab-on-grade foundations resting on piles eliminates the concerns of soil shrinkage due to drought conditions. It also eliminates the need to water your foundation during dry periods which is often problematic as during drought conditions water restrictions are also in place. I've experimented with building several foundations with steel piers and I suspect will begin to see a great deal more of it in the future. Thanks for your video it's a great explanation for how this process works and how it can be a substitution for digging shallow footings.
You dig additional piles next to it per the calculations ( bearing load) and create a larger pile cap to support it. On a commercial scale, this is done when the water table is close to the surface. Basically your building a bridge to support the load. 😊
My concern would be what happens to the steel after 50 years or 75 years I mean, obviously I noticed that it’s galvanized. What does that steel look like structurally after that time frame and how does that translate if there’s a failure with that much weight above it that’s no longer giving it the support that it needs essentially you put all the way onto these peers, so if there’s a failure in several peers in one area may because of water buildup, what’s the potential damage?
The piles are all loaded with a safety factor of 2. We work closely with the engineers to make sure the pile will be able to hold a minimum of 2 times the requirements. The galvanization on our piles conform to ASTMA123 which is rated for 72-73 years of life even in the most corrosive atmosphere.
It depends on uplift requirements. Often times the rock will become the bottom of the pile. Maybe it is the size of a house, that would definitely support the load.
There are a few options. If we have not hit our minimum depth, we often will get engineers approval and move the pile one side or the other. As with any project, having close communication with the engineer helps make the job go smoothly.
A wise person understands any answer given that is based on factual experience .... and I joyfully hope that you find great women in building in your remaining days.
Whoa, buddy! That's ugly. This woman owns and runs this business with several crews who respect her completely. She's put in the work. You don't know what you're talking about. I've built and remodeled multiple properties. Maybe you haven't seen enough of the expert women in construction.
@@alifilmz7316 thank you for the support. I love what I do and the industry. I RARELY see sexism. I love an industry that each person shines based on their skill. At the end of the day, we have no idea who built what, but we do know what kind of skills each of the contributors brought to the table.
It’s always inspiring to watch people who know what they’re doing, do it with passion! Very clever technology. Australia.
Lol, too bad you didn’t see anyone like that in this video.

Thanks. We have reps in Texas. You can see if one covers your area. www.goliathtechpiles.com/find-a-certified-installer

Good post👍
Do the helical piles sit inside the concrete wall like sonu tubes in a poured slab?
Superb! Do you provide consultancy service?
Yes we do
On a lakeside residence, with water table concerns
One benefit of helical piles is that we can drill through water table and anchor to dense soil below.

I imagine it would be fixed the same way they fix failed foundations today with underpinning with more piles.
are there piers in the middle, or just the perimiter?
For this specific house it is engineered for just the areas that require frost protection.
how do you know what torque is enough for load bearing if you only have a PSI/Bar gauge on your hydraulic line
Each hydraulic drill has a PSI/Torque calibration.
What do you do when the rock is to big to be moved?
Get a shovel

@@kirkandpam1749 - exactly.... or the bucket on the excavator works great if the location needs to be exact.
Why not just put the rebar heads on straight so you don't have to trim them? aren't you drilling the hole for it anyways?
Why cut the rebar when its close to the string line and not bend it. seems to me its better to keep as much rebar intact as possible
Great point. Bending is an option as well. We make sure we have the required lengths per engineering before ever cutting.
@@goliathtechutah771why not just turn a little further so the connection holes are aligned for no need to cut once the head is attached?
If a woman is explaining anything involving building im out.
Your loss

This lady obviously knows the details of what she's talking about, and her team seems solid. Don't be weird.
