Used Calcium Chloride on Ground

Would it be alright to spray calcium chloride on the driveways and around things that you don"t want grass and weeds growing. I small grand- children playing on the driveway. I have barrels of the stuff.

Barrels of the stuff's a bit much. But calcium choride on the ground sure does kill vegetation, that's for sure. Is poisonous if ingested to humans and animals. Can't sell it or give it to your local tire guy? Maybe a local farmer that wants to ballast that way?

Here in MN they have adapted the major bridges to sparay a liquid solution of CaCl onto the roadbeds for deicing purposes. Most of it drains off directly onto the river below. It can't be too harmful to people and grandkids or they wouldn't spray it.
They had it on the 35W bridge before it fell but only in the last 5 years of it's 40 year life.
I doubt it was much of a contributing cause in the collapse.

Enjoy your rights of ownership of private property! If it's your chemical and your land it shouldn't matter what anyone else thinks or wants you to do. Too much interference by gummit in the first place without encouraging them by seeking approval.

If it's illegal or something make them catch you! I enjoy letting on to some of the local green fanatics that I still change my oil into the storm sewer like we did 20 years ago. I really don't but it sure is fun to see them get all balled up thinking I do.

It is sometimes LEGALLY used for dust control on gravel roads, as it seems to draw moisture out of the air and clumping the dust. And at the price of road oiling, I expect to see more of it done in my area.

I wouldn't put it on concrete, but it should be fine on gravel. Depending on how concentrated it is and how much precipitation you get, it should keep most anything from growing there for a year or 2, maybe more. I wish I had it! Good luck.

I have started doing that on a small scale to get rid of weeds. Nice thing is its a salt and for the most part does not hurt mother nature. I have 2 or 3 tires full of the stuff that I'm about ready to do that with to kill off weeds and I hope ticks also

I had a tractor that leaked most of the calcium chloride out onto the ground one week. Killed two healthy 30 year old pine trees about 40 feet tall.

Who knows what it did to my water table area. That was 6 years ago - nothing grows near that spot still.

If you have a bunch, you have an asset. The stuff costs over a dollar a gallon to put into tires for the weight.

Someone told me recently that the stuff they use on the roads is Potassium chloride not calcium chloride. Dunno.

It's done all over the place here in New York. It is the standard "treatment" for summer dust control on dirt roads. Some towns spread it dry right out of the bag, and some have tanker trucks that spray it in liquid form.

Why you would want to do it, I don't know. It just leads to rotting out the underside of your car or truck and kills plant-life.

Here in New York, it's bad enough they spread it all winter. I take my best cars and truck off the road just to preserve them - and would like to keep summer as a "rot free" time of year.

Any of the three (calcium, potassium & magnesium chloride) are concentrated salt solutions so the effects are pretty much the same.
Here in Colo. they use magnesium chloride for de-icing and dust control. Like [i:ed8d2ef11d]RobMD[/i:ed8d2ef11d] said it's killing everything on the sides of the roads including pine, spruce, juniper trees and bushes. It also eats brake parts, frames, fenders, wire insulation, etc. The road guys are supposed to be in full haz-mat regalia when they are filling the truck tanks. Back when I was driving 18s we went to PVC gloves since the repeated exposure caused by getting your 'chain-up' leather gloves soaked in the stuff would cause your hands to blister. If it's that bad for the outside of humans it's anybody's guess as to what it does to the insides of anything drinking the runoff from the roads. The trout here have been diagnosed with 'whirling' disease in the past 10-15 years .... about the same timeframe that they have been using the mag-chloride ..... ??? They have actually forced the county, state and city from using it in and around Aspen ..... too hard on the all of the Mercedes Benz grocery getters over there I reckon.
