Concrete blocks for tent ballast. At least one block required at each tent pole.Current ASTM standard for tent ballast is 10 pounds per square foot of tent space. For example, a 20X20 tent is 400 sqft. This tent will require 4000 pounds of ballast. Calculations below are for 500 pounds blocks.
10X10 = 100sqft / 4 blocks
10X20 = 200sqft / 4 blocks
15X15 = 225sqft / 4+ blocks
15X30 = 450sqft / 6+ blocks
20X20 = 400sqft / 8 blocks
20X30 = 600sqft / 10+ blocks
20X40 = 800sqft / 16 blocks
30X30 = 900sqft / 18 blocks
30X45 / 1350sqft / 27 blocks
30X60 / 1800sqft / 36 blocks
