When we used the material (Geomelt®)Saturday night Sunday morning and I think it made a big improvement. So did my guys because we went out Saturday early around 4-5:00 in the afternoon/ evening..started snowing here till like 1:00 AM Sunday morning and we didn’t have to go out again till 5-6 p.m.Snow was coming down at a rate of 1 to 2 in./hr We pre-treated once and we treated again after the snow storm. While most towns were back out again Sunday night, we were okay even at freezing temps and did not have to go back out. Mike and I felt that it was an improvement as we used 200 tons of salt which like I said we’ve been using 450 tons per storm I am very happy and I and I’m glad we got in touch.
