Yeah, this topic has been done to death, but I have a specific question that hasn't been discussed much. I'm hoping the "experts" here with experience can offer some help.
Over the Summer, I built a storage bunker from concrete blocks. I filled it with a fine stone mix that a local quarry sells for anti skid. I covered it with a heavy duty vinyl tarp and secured it tightly with bungees so no rain or snow could blow in. The material was completely dry when I placed it in the bunker but it still froze over to a depth of almost a foot under the tarp. I had to break it up with the backhoe to load the spreader. After I finished spreading, I reloaded the spreader with dry material from under the frozen layer. The spreader has a cover and it was parked inside an unheated barn, but it froze up again inside the hopper. I have no idea where the moisture is coming from.
It looks like I'm going to have to add ice melt but how do I mix it? Can I just spread it on top of the frozen pile and hope it penetrates down far enough to prevent freeze ups? What ice melt is best for this? I'm not overly worried about corrosion, since the spreader hopper is heavily galvanized and all the moving parts are stainless steel. Cost is always a factor as well as possible vegetation damage, but the road is gravel with no concrete or asphalt to worry about.
Next season, I'll mix ice melt into the material as I load the bunker, but what do I do with the existing frozen 23 ton pile?
Thanks in advance for any ideas or solutions!
