Pocket Penetrometers are for use for cohesive soils (Clays or Silty Clay). They are not for use for granular soils (sand or rock). The tool for granular is a Housel Penetrometer. I use these everyday as a geotech. Love having clay as bearing soil as i dont have to lug a 50lb housel around with me.
What if the spot where you are pressing down happens to have a rock underneath? Wouldn't that distort the reading quite a bit? Would you have to have several spot checks to be sure?
Thanks for the video. It sheds light to the soil bearing capacity. I need a simple opinion to design a foundation against the weight of the house building materials.
If I'm planning to build a slab on grade, can I use the penetrometer on the surface of the ground or do I have to dig down past the sod layer to undisturbed soil? The house site is currently a grassy sloped area of the property and there are wetlands down hill of the site about 200'.
word-forthat amount , I could throw a foot of gravel under the entire footer to stabilize Qould spend it on compacted gravel under the footer Q-not that bad in metro DC, but NOT in insignificant cost at al.

I don't understand why people are taking these risks without performing geological survey first.

Thank you Michael!
Great video!
Hola tendrás trabajo para mi me dedico a eso
FYI a geotechnician in bay area charges 8-10 grands vs. 250 in the video

I wish I had hired geotechinical engineer before laying foundation
Does your city not require a geotechnical report for a foundation permit?
I don't want the authority to take care of my house
hope communism is out of the USA

That’s strange. Which town is that? Geotechnical reports are required by code I think.
@@sherifnabil9663 You would think the town would already know from previous reports.
Nice
Its all fine and dandy until houses are no longer affordable. Oh that’s right……they already are
You gotta spend a million dollars for pure bullshit - before you even stick a shovel in the ground. All money that could be used for materials.
