Driving T Posts through Sedimentary Rock Layers 

Six years later and you're still helping people with your advice. Thanks for the tip

Thank you , I learned a very good hint today . I faced a similar problem and had to put the project on hold . I may go back and finish my fencing project now . I admire the fact that your son is willing to offer help unlike many kids of his age. Salute from Sadi Arabia 🇸🇦

This is extremely helpful! We have 12 acres on hard bed rock to dig thru in northern Arkansas. Putting up a fence seemed like a daunting task until I saw your video. THANK YOU!

Thank you! I live on a 10 acre limestone quarry masquerading as a lawn. This will be a big help.

My soil is Glacial till, lots of big rock. I use a 1" bit on my roto-hammer. 1 inch gives a perfect size hole to drive a T post in.

THANK YOU! I cant even get a t post started around here on my ranch and I need to get something to make it through for at least t-posts.

Dang, that’s some hard ground to work. Get some earplugs. Hearing damage accumulates. Then it crosses the threshold where it’s a problem.

We just bought 10 acres of limestone (and cactus). This video helps tremendously. Thank you.

Helps tremendously!!! Thanks for posting! I’d use a hammer drill with a big masonry or concrete but though. I too have a whole bunch of posts to drive. Will definitely use this technique. 👍

I have been having such a hard time with our soil too. This drill idea im gonna have to try!

What type of drill bit are you using?

Several years ago was asked to help some friends fix their fence here in central Montana. If your not familiar with this area, we have similar shale and sandstone as well as many bluffs/cliffs of this rock on the edge of ravines and coulees. I am a contractor by trade, but also have a small ranch. I took my small portable gas powered generator and a Milwaukee hammer drill with a 3/4 inch masonry bit to drill holes not only in the layered dirt, but also straight into the solid rocks of the bluff right up to the edge. No more 'A' frame wood constructs or tree branch barricades!!! Once the hole was drilled, pounded those 'T' posts straight in!! (Might want to back fill those holes in the rock to keep the water out. Expanding spray foam works great.)

SDS Max rotary hammer as another recommended. It would be a lot faster on the T post install is my guess.

Hell ya. That's my problem on my ranch. Even my backhoe can't get a post in but a dill and bit worked for some holes. I got tied of digging 6 foot diameter holes to get a 2 in post in.

Thanks for the video, it was my smoking gun convincing a old timer that wanted to know if there were special tools made for getting tposts into rockbedded areas along a new fence line located in very remote rugged areas. Opportunity comes to the prepared mind.

This is a great suggestion. Thanks for taking the time to make the video and post it.

Thank you so much for making the effort to show us.

It sure helps me..... I am in Arizona and there is no soft pack here we have rock and a substance called Caliche which is actually the base to make Portland cement...... never thought about drilling and i think it will be a big help here..... thanks a bunch

Thank you for sharing. Very helpful as I have land with lots of rocks as well and will be installing some posts this spring.

Thank you for the tips we have tones of rocks here in Texas and its so dry the dirt is like concrete right now

Awesome, just starting my project in the Texas Hill County and after 6" of soil it's solid limestone. This will help!

Just had a professional fence installer tell me he couldn't put in all my posts due to rock. He would have to rent a heavy duty compressor to power a jack hammer. He didn't even put in half of the posts he was supposed to because of rock. Perhaps my rock is harder than your sedentary rock, don't know, but thanks for your video.

Dang, that's hard work! Pretty ingenious!

Hello there, As a suggestion add a counter weight to the T-Post to assist in getting it past the hard pan, and take some strain off your shoulders, Best wishes KPP nz

I use a 1 3/8 masonry bit - one hole ~ one pole

Rotohammer and the biggest drill bit does the job usually Home Depot has them for rent

Thank you for the tip. I may try with the drill. Helmet and safety goggles for the kid...​

Thank for sharing the info, we are facing the same issue with underground rocks.

Well done. I want to try with rotor hammer drill and a rock/cement bit

I used a 1” masonry bit with my hammer drill in sandstone.

I can't fu ck ing believe I never thought of using a masonry bit. I used them all the time running pec pipe and wires through brick n cement etc. Sheesh a light dawns on Marblehead

Facing some rock on my property. Will definitely do the drill bit, but im also going to check in on renting a power post driver.

Yeah. I used a hammer drill with a generator and a half inch long mason bit in limestone shale.

THANK YOU !!! I had the same thought but was told by all the men around here, me being a female, that it would not work. Since I have the hammer drill I will go get myself a nice long drillbit, perhaps a spade bit?

Thank you for posting this , huge help ! !!!

Thank you for this video. We just purchased land by Eufaula OK. Same soil conditions. Drove two posts 6” thought I was going to die. Will be using you method. What size and brand of bit were you using.

Good video but did you film it with a pager?

get a rotary hammer and an extended length bit

Thanks!

I've been using hole spray in the 40oz can.

Wow that is so helpful! Thanks for taking the time to share this video!!

I need to drive two posts in fast-moving creek with tons of rock

I use my Jack hammer. Needs power so not as portable as your drill. But same concept.

Awesome tip! Thank you!

A very nice tip. Thanks.

Great tip and also the tip, tip!

Very good idea. Thank you

Literally caught my cordless drill on fire drilling holes in soil

Thanks! Will you come up to Eastern Washington State and drill into this cast-iron volcanic basalt? I rented a Rhino driver and it's a godsend but I am defeated with what's under the soil. I know a fencing contractor who uses a skid steer mounted hydraulic spike and that got the corner posts in, so I'll need him to come back out

I can say that post is not coming out of the ground easy, its stuck there for life LOL. All some tip.

Good Idea , Thank You .

Dude thank you so much 🙂

Will try it next time!

If this is going to work my friend you will save/make me a lot of money... I had myself thought about drilling a hole, but it did not cross my mind to use steel for the posts... What a dumbass 🥵... Will post results in a few months (we have a lot of limestone on our pastures around here - maybe 5-10 cm of earth, below that mostly limestone)...

Genius !!

what kind of bit are you using?

Ppreciate it

Sure hope you had ear protection

you should have been an engineer or a dentist

Why is this listed under comedy? It wasn't funny, but it sure is helpful. THANKS!

hammer drill

240p we meet again

why in the world would you be using a non hammer drill with a WOOD boring bit for rock ? WTF ?

You should have rented a large electric hammer drill !

First off get a better ladder. Second and more importantly get the kid a helmet. First time off grid ? Safety First.

I have been building fences for years and placed t-posts in rock 75% of the time. This has to be the biggest joke I've ever seen. The drill is not a hammer drill, the drill is small, the bit is short, and HES NOT DRILLING THROUGH ROCK. Wake up people, us common sense.
