De icer
 

can we use waste tank water as de icer dor driveway?

I wouldn't.
The salt will damage a concrete driveway and the runoff will kill the bordering plant life.

Hmmm, Good Question.

Now how is this different than dry salt that you use on driveways. If you can keep it off the grassy areas, then you may be good... But the problem, compared to dry driveway salt, is that it is liquid, so it would probably run everywhere and also run off the driveway before it can do any good.

So probably a waste of time, and probably will kill everything around as Mitch stated.

Sidewalk deicer is I think Magnesium chloride based.

The spots in my basement where I've had SW tanks the concrete is all damaged from spills etc. over the years.

I was in a pinch and used instant ocean as my sidewalk salt. Melted the ice in record speed but also melted the concrete :redface:

you guys are giving me ideas for my window dilemma. i'll seal a reservoir to the side of my house and fill it with sw. screw concrete cutting right?

Wow, I did not know salt eats away concrete!!
The problem is I have a big block of ice sitting right between the driveway and the road. I am trying to find a easier way to remove it. Maybe set a fire beside it?:idea:

For our office sidewalks I use an "environmentally friendly" melter that we get from W.E. Greer (near Blackfoot and Glenmore). I'll probably be in at the office on Sunday, so I can get the name of it then.

If you pour saltwater on your driveway you will only make more ice. Saltwater at 35ppt (approx 1.026) freezes at only -2 degrees Celsius.

I have the issue but with the concrete patio out front. THe heavy snow and ice in Ontario knocked my eavestrough clean off and iceicles and water (from the snow on the roof + daytime sun) collects on my patio then flash freezes at about 6-7pm. its usually around 1-3" thick and no ice blade will even make a dent in it. I took fistfulls of road salt (sold at RONA in 40kg bags for $10) and covered the ice so you couldnt even see the ice (i used ALOT) - it was probably -10 out the time. A couple hours later and salt had eaten through almost all of it - you can actually hear it melting the ice - makes a poping noise. The key is to have enough salt on top to melt the middle and bottom layers of ice after the top layers are melted. I repeated this today and had the same results.


Its just a matter of using ALOT of salt and at $10 for a 40KG bag you cant go wrong. I rather waste $50 on salt a year than have the mail person slip and sue me or worse get permanently hurt. Also concerned about my wife carrying our 1 year old out to and from the car. There is some eco-friendly stuff out there but its like $20 for a 5kg bag.
