How to break a 2 inch thick concrete foundation.

Dear friends:

The previous owner of my house built a storage house (about 10' x 8') in the middle of my backyard. Since it looked ugly, I decided to remove it. I have been able to remove its top portion, but I could not break the concrete foundation that is about 2 inch thick.

I have thought of buying a big sledge hammer or renting a power hammer from HomeDepot in order to break it. Could someone tell me whether a sledge hammer will do? Do you have any better idea besides a C4 suggestion? Thanks a lot.

BTW, the squares in the picture are about 1' x 1' each.

Best regards,

Eric

Drill a hole through the concrete, and put a piece of decent-thickness sheet steel on the inside. Then, run as large of an eye bolt as you can through the hole, and secure it to the sheet steel (if the bolt goes through the steel, put a nut on the bolt so it won't pull back through). This should make for an anchor.

Then hook the eye to a piece of chain that's hooked to a pickup truck, and use the truck to start pulling away. Assuming the sheet steel, the eye bolt, the chain, and the anchor on the truck are strong enough and you have good traction and sufficient horsepower, the truck should eventually be able to pull the wall down in small enough pieces to be able to haul away.

Just a (semi-redneck ) thought Good luck!!

A sledge should do the job just fine. Swing high, swing low....

Only 2 inches? Boy, I must be tired...I honestly thought he had said two feet.

Okay, nevermind my suggestion...a BFH should do just fine.

Find a construction site of any kind near your home stop and give the operator a $50 with your address on it and tell him there is a case of beer included when he's done.

Get sledge hammer. It should work fine. If not, then at least you will have a sledge hammer.

Had someone uproot a 4" deep concrete path in our back yard. He used a long handled shovel as a pry bar. No bits and pieces flying around, and IMHO good size slabs are easier to load on a truck than a pile of rubble. Hopefully your pad will break apart rather than break whatever you use as a pry bar.

Don't forget to lift one side of the slab (shale bar, pry bar, shovel,etc.) and place a brick or stone under the slab before trying to break it. A slab on grade is much harder to break than one that is suspended above (experience teaches us much).
