First, thanks to all for the help identifying the Force 12 XR-5 and (probably) Ham IV rotor on that HDX-555 tower last week. Once the tower is gone, the widow really wants to have the concrete base g
I did it once- rented an electric jackhammer and took out an entire Rohn 25G base. It was a royal pain in the @$$, but was done in less than a day. Going down only 6" or so shouldn't be too bad. It w
Rob: When I worked at an electric utility as a substation engineer, I would specify removing of concrete pedestals from abandoned equipment by the jackhammer-and-topsoil method. Our company required
I had to get this done on two tower bases recently. Coincidentally, I ran into a guy busting up a concrete base in a parking lot, where a car accident had damaged a pole. In all three cases, the tech
If you have a big slab, you can rent Bobcats with a jack hammer attachment. They make quick work of busting rocks and concrete. 73s de Jim W5IFP . _______________________________________________ ____
Rich, I have personal experience with this. The older (stronger) the concrete, the more difficult this will be. I moved out of a QTH in Ohio that was previously owned by a ham who had been there sinc
Speaking of old...unless you are under 42 and do this once a week, consider what your body will think, about five hours into this project. Best done with one finger...on the telephone dial, to someon

Hi Rob, In the trades, the tool is referred to as a "demolition hammer". They are offered in various weights... 45#, 60#, 90#. Years ago, I had a 6'x9' concrete slab I needed to replace. It was aroun
Yes... same technique for removing old patio slabs and swimming pools. 20 year old concrete with rebar is a chore. An alternate solution is drilling holes and using the stuff that expands and cracks
Demo'ing a slab and a big block are VERY different. With a slab, once you get it cracking, it's easy to propagate the cracks and keep chunks coming off. But breaking up something like a 3 foot diamet
Dynamite is a whale of a lot more fun!<:-)) OTOH it's a bit more difficult to get the permit now days than it was when I was young. 1/4 sticks of 40% done a little at a time will turn the whole chunk
It is and it's very common. If done along the rebar the concrete will come right off. 73 Roger (K8RI) _______________________________________________ _______________________________________________ T
I previously busted up a concrete block (about 1/2 cu yd) also using a 60# demolition hammer. Doing so was no more difficult than breaking up the 8" thick slab. The slab wasn't a patio and wasn't hau
Have you thought about just digging a hole next to the base a bit bigger and a foot or two deeper than the anticipated height of the base. Push the base into it and then fill in the hole where the ba
