Estimating Endura Safe Needs For Playground Projects
- Calculate your square footage – (Length x Width)
- Determine your required fall height rating:
• a 4″ installed depth protects up to a 9 foot fall height
• a 6″ installed depth protects over 7 feet up to a 15 foot fall height
• a 9″ installed depth protects over 15 foot fall height - Multiply Square Feet by:
• 9.3 for 4” of installed depth
• 14.0 for 6″ of installed depth
• 21.0 for 9″ of installed depth - Divide that number by 2000 to determine how many tons of material you will need.
Example: A 20’x20′ area that needs 4″ of material would be calculated as follows:
20′ x 20′ = 400 Square Feet
400 Square Feet x 9.3 = 3,720 lbs
3,720 lbs+ 2000 = 1.86 Tons of material needed, which is equivalent to 106 Retail Bags, or 2 Super Sacks
Example: A 20′ x 20′ area that needs 6″ of material would be calculated as follows:
20′ x 20′ = 400 square feet
400 Square Feet x 14 = 5,600 lbs.
5,600 lbs.+ 2000 = 2.8 tons, which is equivalent to 160 Retail Bags, or 3 Super Sacks
