"auger style" deck supports


can someone help me find this on line - saw this on a home reno show last week - steel posts with a kind of a "flat" auger blade on the end - the post itself looked like it might be 4 or 5" in diameter (guessing) - they drilled these things down about 5 or 6 feet like a normal auger - and then just left in place. Apparently the post can support something like 5 tons once it's anchored...? no concrete, or digging - drill 'em down and go....

sorry I just caught a few seconds of this in the middle of some other distractions and the details are sketchy - just curious to know a bit more about this system

thanks

Sounds like a helical pier or mini helical pier. They typically require a special hydraulic attachment on a skid steer or similar equipment to screw then into the ground. Many hardware stores cary smaller ones used to anchor structures down so wind won't blow them away.

That system is very dependant on the soil type and the moisture in the soil (especially with seasonal conditions)

The concept has been used for years by engineers, but it has to be used properly in the right soil.

gotcha - just digging around for info - this one seemed kinda cool - something you could screw down beside existing (crappy) piers without a lot of digging, etc.

appreciate the feedback
