Concrete breaking Dexpam

Concrete breaking Dexpan

Have to plug this stuff, Dexpan...Break concrete by expanding cement

Had a vertical wall 4 feet high, 21 long 14" thick, Did not want to pay someone or rent a large compressor and jack hammer. Tried this stuff, works great. What ever concrete, horizontal or vertical, you drill 1 1/2" holes every 1ft along the crete and fill with Dexpan, wait 24 hours and the concrete mass is broken. Might sound like a great ordeal to drill all the holes but it only took me about 4 hours to drill the holes. Upon first using Dexpan, I thought it was a scam, as after 12 hours there was no cement breakage, next morning the wall was cracked into manageable 1 foot chunks. Had some rebar, which I still was able to get at to cut, by using a crowbar.
To have someone break it it would have been $1500.00, to rent a compressor for a weekend, likely $1000.00.
Cost about $125.00 for the Dexpam delivered, I purchased a hammer drill with some of the cost savings; could have rented for about $80.00 but I wanted a new toy. Great product

ive heard nothing but good things about the stuff. I was going to use it to break up a slab, but ended up leaving it.

Cool. I might have to try it this spring. Thanks for the info.

Should have had that today, had to run a jack hammer for 45 minutes or so. It sucked

I use it often when in a delicate area when too much oppertunity for an oopus with the large equipment.
We call it Chinese dynamite, works well.

Used them for days on end, have permanent hearing loss for certain frequencies. Loads of fun on vertical walls.
