Went on a little Ski Junket and in my absence we had a rain/sleet/snow event. My guys did everything right-except for completely missing the three biggest lots we plow for a customer that pays us around 70k per year!!!!! As the ice was about 3" thick, I salted the crap out of them on friday and attemted to scrape them yesterday. The slush moved ok but the thick ice is bonded to the asphalt. Any advice on what I might do ( other than pray for sun) to solve this problem. I already have 10 hours and $130 worth of salt that I, in good concience, cannot bill for.
