Alpine Barkblowing & Hydroseeding

I have applied my own bark by hand for 13 years. When I asked Alpine to give me a quote, they quoted me significantly more than I had historically applied. I accepted the quote of 16 yards. I was there when the bark was delivered (18 yards). I watched the process and looked in the truck when they had completed (1/3 remaining). This means they actually applied 12 yards, not 16 yards. There is no way to know how much bark is loaded in the truck initially unless the product came with a loader receipt from the bark yard. I felt that the business over-estimated the amount of bark I needed and then under-applied the quantity that they promised. I believe they do this to all of their customers. How would anyone know if the bark looks nice after it has been applied? There is no accountability and the owners just say that they know "by looking at it" how much bark has been applied. They should have to load up the amount of bark in the quote, show proof of that amount, and then empty the truck in full. It is a racket - an industry that is not held accountable and run by people lacking integrity.
